“Shrubs in the garden, perennials from seed and garden surprises”

Final Thoughts:
“Shrubs in the garden, perennials from seed and garden surprises” by Mala Gunadasa-Rohling

A nice surprise greeted me one morning a couple of weeks ago - I looked out the window at the weeping willow that hangs over one corner of our garden from the neighbours (a very nice ‘borrowed’ plant) and saw that the lower branches were covered in beautiful pink blooms! During last summer, without anyone noticing, the clematis that grows along our fence had reached up and grown into the weeping willow, and was now in full bloom.

I have a beautiful forsythia bush in the garden, in direct view of the office window. It has lovely fresh green leaves and extremely graceful, tall arching branches. This bush wasn’t pruned last year, (unlike the chopped back one right next to it) and was left to grow into its natural shape and height - about 10 feet tall! This would be great if the weather cooperated: I expect annuals and some perennials to be affected by a heavy rainstorm and flop over, especially the topheavy ones like paeonies, delphiniums, and the delicate, wispy wildflowers I am so fond off. That is why there are always instructions to stake them…But shrubs? Shouldn’t woody shrubs stand up by themselves? I always thought so, but not in the case of this forsythia! On a rainy day, or even the damp, misty days of a Vancouver spring and summer, the days that seem like 200% humidity, the moisture collects on all the leaves and branches and folds them over. My lovely bush looks like a sad, overgrown mop turned upside down in the garden. Pathetic. Almost horizontal, it leans precariously over the other plants around it, threatening to knock over the lilies coming up beside it.

What happened to this bush? Why would it grow so tall? It was probably overfertilised, resulting in far too much fresh, lush growth last year that hasn’t developed any woody structure and so flops around badly. It would have better to grow half that height and have the strength to support itself properly. It is also growing in a rather shady spot - it probably needs more and stronger sunshine to prevent the lax habit, just like seedlings get leggy if they don’t get enough light.

The best thing to do for this plant is to give it a severe pruning right after flowering (oh, did I mention that these nice long stems barely had any flowers on them at all this spring? And I was so looking forward to a lovely show of bright yellow…it never materialised). Remember that forsythia roots from cuttings very easily, you could quickly have a whole hedge of it. It actually makes a very attractive informal flowering hedge - just keep it fairly low, no more than 4 feet tall.

The other shrubs in the garden are doing very well, except perhaps for the rhododendrons. These look a little sickly and sparse…seem to be losing a lot of the lower leaves, and the rest are a bit yellow. This is probably because of bad drainage, most of the garden is a bit of a bog, so much so that I can watch the corner of the patio sinking into the ground after a rainfall.

The ceonothus bushes are doing fine, as are the witch hazel, hebes, hydrangeas and skimmias. The Pacific dogwoods are not almost the size of small trees, very attractive in shape and form. They are a bit late in flowering this year, only now are the first pale, creamy blooms appearing.

Growing perennials from seed is particularly rewarding, as the results will last for many years. My Shasta daisies, lavender and lychnis will be blooming very shortly and I’m really looking forward to them! The daisy buds are numerous enough to risk cutting some and bringing them indoors, as they are supposed to last quite long in a vase. The lychnis, with its soft, hairy silver-green leaves should make a great contrast to the brilliant, magenta flowers. I love the bright colour of this flower, and there is a lovely white version also which I must get.

As for the lavender, who doesn’t like this plant? Easy care, will grow in poor soil, doesn’t need much water, and just a trim at the end of the season to tidy it up if you wish. The fragrance is unforgettable, as is the colour. Delicate yet hardy at the same time. As useful as you want to make it (you can make soap and cosmetics from it, use it for scent sachets or potpourri, even cook with it), it also looks lovely just sitting there in the border or in a pot on the patio. I have just finished reading a book where the author tells a story that takes place in the lavender fields that used to cover the hills of southwest London in the 1800’s. A particularly touching story of a young girl and her sick baby brother takes place in these fields…I will never be able to look at a lavender bush again without remembering Lucy and Horatio. It is truly amazing how your perception of plants changes with experiences like this - where a flower has a part in a good book or movie, or even more strongly, if it is part of a friend or relatives treasured garden…if you can possibly get a cutting or seeds from these plants, or resort to buying a similar plant from a nursery, even if it is the ordinary, everyday variety, it is guaranteed to produce more pleasure and memories for you than anything that doesn’t have this ‘background’ or ‘association’. Make sure your garden is filled with your own personal favourites to really get the most enjoyment from it.

Increase your vegetable production with Succession Planting

June In-Depth How-To:
Increase your vegetable production with Succession Planting

Many beginner gardeners plant their crops in the spring, harvest the vegetables, then clean up the garden and wait till next year to start all over again. It is very easy to get more enjoyment, not to mention more production out of your garden. Try succession planting for a constant supply of fresh produce all summer (and into autumn) long. No matter where you live, you can harvest at least two crops from the same area of the garden during the growing season.

Divide the crops you will be growing into two different categories : cool weather and warm weather crops. Crops that do well in cool weather include: beets, broccoli, cabbage, carrots, celery, kohlrabi, lettuce, parsnips, peas, radish, spinach, mustard greens, kale, turnips and swiss chard. Plant these varieties as early in the growing season as possible for your area of the country. After you have harvested these varieties from the garden, follow up by planting your warm weather vegetables. 

Warm weather vegetables include: beans, corn, cucumbers, eggplant, melons, okra, peppers, pumpkins, squash, tomatoes and watermelons. In a few areas of the country, a third planting of the cool weather crops can be planted again in the fall. Below are some examples of succession planting.

 

 

In many areas of the southern US, the growing season can be over 230 days.

Start by planting lettuce, spinach or other cool weather crops that can be harvested in 60 to 75 days. Follow that with a planting of beans or cucumbers (these also mature in about 60 to 75 days). This will still leave you with about 70 days for a late planting of root crops, cole crops or greens. Or as a second crop, you can plant corn, tomatoes, melons etc. and still have these mature by the end of the season.

In the northern areas of the country, you also can get two crops out of the same section of the garden. With as little as 150 days in the season, you can plant an early maturing lettuce or radish and follow with a crop of beans. In northern states with a longer growing season, tomatoes, melons, corn, etc. can all be planted after you have harvested the earlier crops of lettuce, spinach and cole crops.

Just remember, in order to plan succession planting, you have to know how many days each variety takes to mature and how long your growing season is. Also, do not plant members of the same family in succession, as this could put a strain on your soil’s resources. More on this aspect of vegetable gardening, known as ‘Crop Rotation’ in a future issue of the Journal.

June Garden Action Items

It’s official - summer is here, although the rainy and cold weather that we’ve been having so far in Vancouver (and also in England if Chelsea coverage is anything to go by) wouldn’t let on to that fact…still, there is lots to do in the garden now, so out you go!

  1. Start to sow quick maturing vegetable seeds such as lettuce and radish on a regular two-week basis for the next couple of months. This will ensure a steady supply of fresh produce that is ready on a staggered time frame, and doesn’t mature all at the same time. Remember that these quick crops are a great starter plant for children, as their speedy germination and growth can be easily monitored and appreciated before they lose interest.
  2. Make sure that watering of newly emerging seedlings and freshly planted out flowers and vegetables is done very regularly! Don’t let them dry out too much at this delicate stage as they will not have the resources to recover, as will more established plants.
  3. Keep a close and vigilant eye out for garden pests. A small infection caught now will be much easier to control than a rampant infestation in a few weeks time. Aphids, blackfly, greenfly, slugs, etc can multiply at an alarming rate at this time of year. Try hand picking them, squashing them between your fingers (wear gloves if you are squeamish!). Some sources suggest a strong spray with a water jet to dislodge them - I don’t like this method personally as I’m sure they’ll be back within minutes? A mild soap solution seems a much better bet. Whichever method you choose, the trick is to catch the bad bugs early and regularly.
  4. By now almost all danger of severe frost has passed in even the coldest areas, and bedding plants can be safely put outside into the garden. Make sure they have been slowly acclimatised, though, or the sudden shock of moving them from a warm, sheltered indoor or greenhouse location straight outside can set them back quite a lot.
  5. It’s time to start the regular schedule of mowing the lawn, and if you haven’t done so already, the blades can now be lowered to their final desired position. If you cut regularly enough so that only a tiny bit is taken off each time, you won’t have to worry about the clippings, just let them fall back down. If you wait until you are removing an inch or two, it is often tidier to collect the clippings, either at the same time with the bag attached or raking up afterwards. Remember that these clippings are great for the compost heap, or used as a mulch (after they have been laid out to turn brown).
  6. All manner of vegetable crops can be sown outside throughout this month and will mature in time to produce a healthy harvest. Try beans, carrots, squash, peas, corn, lettuce, spinach and beets for a good assortment of fresh produce, guaranteed to taste better than anything you get from the supermarkets!
  7. With rows of vegetables planted earlier this year, it is now time to thin them to the correct spacing. This depends on the crop grown, and will be indicated on the seed packet. Firm the soil back around the row and water gently to settle the soil. A row of plants that is too close together will never reach its full potential, and the final produce load will be smaller than if you are brave and thin out now. This is a difficult job for some people (I definitely fall into this category!!) but remember that you can almost always use these little seedlings for fresh and trendy ‘baby vegetables’. Especially delicious are tiny carrots, beets and leeks which can be eaten whole, leaves and all in fresh salads or braised/grilled lightly in a pan.
  8. A little fertiliser sprinkled around rapidly growing shrubs and perennials will help them flower to their best. Scratch it in gently around the plants, not directly up against the stem but in a wide circle around the base. Water in if rain isn’t expected shortly.
  9. Now is a good time to divide those spring flowering perennials such as hellebores, primulas and pulmonarias. After the flowers have faded, dig up any old, established clumps and gently divide them into smaller pieces, each with its own section of leaves and roots. Replant these sections where desired or share them with friends.
  10. Early this month, cut back spring-flowering shrubs such as forsythia. This will keep the bush in shape as it tends to get a bit loose and straggly otherwise, as well as quickly outgrowing it’s allotted space! Cutting back at this time of year rather than in late autumn will ensure a good crop of flowers next spring as the plant has time to grow the shoots which will bear blossoms next season.

May Garden Action Items

May and June are really the best months for many perennials, before the real heat of the summer cuts them short. Work in the garden takes on the familiar rhythm of seasons past, with some staking, potting up seedlings, preparing beds for annuals, planting out, etc etc. A busy time, but filled with promise and good things ahead…

1. Pot on young plants and rooted cuttings regularly to ensure that they don’t get potbound and slowed down in their growth. At least every 10 days to two weeks, they should be checked by gently removing them from their pot (turn it over and tap out the rootball). If you can start to see roots around the edges, it is time to put it into the next size pot. If you have left it too late and the young roots are circling around the bottom and sides of the pot, don’t despair! Just rough up the root ball a little to loosen the tight roots and place gently in the next size pot. In drastic situations, remove a bit of the overgrown roots by cutting them away.

2. Continue sowing seeds of annuals directly into the ground until the end of this month. They will grow and bloom this season. Try easy and reliable favourites such as cosmos, lavatera, nigella, california poppies and marigolds.

3. Plant some marigolds (tagetes) around the vegetable plants such as tomatoes and carrots. The strong smell of the flowers can help in keeping insects such as whitefly and carrotfly away from the crops. Besides, their cheery and bright colours add interest to this area of the garden until the fruit ripes. Nasturtiums are great for this job also, and are very attractive to aphids, and may keep them off other plants. A few annuals also help in attracting pollinating insects to improve the crop yield in a vegetable area.

4. Feed your roses now as they are just starting to grow vigorously. If you are using a dry fertiliser, scatter around the base of the plant and scratch it in gently. Water if the soil is dry to start it working.

5. Also feed your flowering bulbs as the flowers fade. If you can deadhead them, that’s great, but leave all the foliage intact (don’t bend them over, tie them up, or cut them off). The leaves are the only source of food for the bulb underground, and if they are removed before they have done their job and replenished the bulb’s nutrients, there won’t be any flowers next year. If they are unsightly where they are, it is fine to remove them intact gently with as much soil around them as possible and move them into a nursery bed or quiet corner of the garden where they can finish the season’s growth unnoticed.

6. Don’t be in a hurry to plant out summer bedding or tender annuals - bad frosts can still occur at night until the end of May. Keep them in the greenhouse or coldframe until the end of this month, or be prepared to act quickly if necessary to cover them up with fleece or other material if a cold night is forecast.

7. Now is the time to put stakes in place for all perennials that may need them! Don’t wait until they’ve already toppled over since at that time, they will look terrible propped or tied back up. Plant supports come in many shapes and sizes, from fancy willow cages and small trellises, to shiny metal canes. A simple and effective way that also blends in unobtrusively is to use pea sticks - small branches cut from any shrub or plant stuck into the ground around the plant to be supported. The new branches will grow up around and through the pea sticks and be supported gently without having to be individually tied in.

8. Lawn care - you may need a slight trim at this time, but make it a gentle one with the mower settings as high as possible. They can be lowered later as growth gets more vigourous. Lawns benefit from a raking to remove winter debris such as old leaves and moss. If they are compacted, try aerating them by spiking or even pulling out cores (make sure these are raked up and composted as they look terrible otherwise, and probably plug up the holes they were meant to open!)

9. Prune back stems of hellebores and primulas that have finished flowering. If you want the plants to set seed, leave one or two stems to finish maturing. This will tidy the area, save the plant some energy and prevent too many unwanted seedlings spreading around.

10. Harvest rhubarb now by gripping stems firmly at the base and pulling away from the crown sharply. Try to remove any flowering stems completely.

Beneficial Insects - Part III

“Beneficial Insects - Part III” by Sharon Hanna.Lacewings are unmistakeable: pale green, with slender, elongated bodies, and two pairs of extremely delicate netted wings. Their larvae are similar to that of the ladybird beetle (ladybug), in that they resemble little dragons or alligators, except that they are beige with brown markings.


Adult lacewing

While adult lacewings require nectar for energy, pollen from flowers, and drink the honeydew from aphids, the larva eat anything, and lots of it. It is estimated that during the larval stages, one lacewing can eat up to 800 aphids. 

Known as “indescriminate” feeders, the larva behave like teenage boys, walking over 8 linear miles in one short larval season, consuming anything which lies in their path, including thrips, red mites, spider mites, leaf-hoppers, and also caterpillars. Unlike other beneficials, lacewings produce several generations each growing season, making them possibly the most effective predatory insect we know.


Lacewing larva

Have you been hankering for a “water feature”, for haven’t found a good enough excuse? Here is a great one, for lacewings love (and need) constant humidity to support their dainty physiological structure, and will stay around if you have a garden fountain which will create a constant mist! Or, increase humidity by close planting and using mulch. Lacewings are nocturnal and phototropic (attracted by light), so garden lighting will give them a real welcome. 

Adult lacewings feed on flower nectar, and their number one favourite is Cosmos, and especially the white variety. A good one is aptly-named “Purity”. Other useful plants for them are fennel, alyssum, achillea (tansy), all easily raised from seed, and fundamental to your bio-diverse garden.

  
Alyssum (left) and achillea (right) attract lacewings to your garden

While we are all the subject of beneficial insects, it’s useful to remember that today’s caterpillar is tomorrow’s butterfly. It is another of life’s ironies when one finds that in order to attract butterflies, you must be willing to tolerate damage to the “host” plant.

Years ago, I ripped out a patch of fall asters for that very reason - chewed leaves, caterpillar droppings, and what I felt were unsightly webs. Undoubtedly my backyard is less populated with certain types of butterflies! 

Mother Nature prefers a riot of Everything, including leaves with holes, and she likes it messy. Weevils, slow-moving snub-nosed creatures, might take a few bites of the rhododendron, but they are also food for the kind of birds that you want to attract. 

So, you are invited to play in your own biosphere! And, remember - if this sounds overly bizarre or time-consuming, and relaxing appeals to you, there is another way to help - neglect a part of your garden, and let it be. Leave a rotten stump, stones, and leaves. Mother Nature called them leaves for a reason. Tell your neighbours you have become a “zen” gardener. You are exonerated, for ‘lazy’ gardeners naturally generate biodiversity, a great justification to sit back and watch your garden grow.

How To Photograph Flowers

It’s spring in many parts of the world. For those of us who spent the winter trapped inside, spring means, among other things, an irresistible chance to grab the camera and start capturing the first blooms of the season. Yet, how do you turn those shots of your favorite blooms into something special? Here are some tips on how to take better flower pictures from the world’s largest photography school, New York Institute of Photography (NYI).

First, walk around the flower to see how it looks with light coming from different directions. Watch carefully when the light (usually, the sun) is behind the flower, coming toward the camera. Often, the petals will glow with beautiful iridescence. This is called “backlighting” because the light is coming from the back of the subject (in this case, the flower). Backlighting is often the best type of lighting for translucent subjects like petals.


Raindrops and dew on leaves and petals add highlights and sparkle to a picture. Shown here are lupine leaves. (MGR)

However, don’t despair if there is no sun. Gray and overcast days provide great opportunities for flower photography. The lighting is more even and there are no shadows. Rain turns colors more intense. You can even carry a spray bottle to create rain droplets on the sunniest of days. Even night photography is an option. You’ll be surprised at how attractive a flower photo can be when illuminated by flash.

Second, to make a flower picture come alive, wait until something adds life to the flower - for example, a bee alights, or a spider crawls into it, or a hummingbird pays a visit. It takes patience, but it pays off if, for example, after you wait a few minutes, a butterfly lands on your flower. Shoot! The picture you get will be great.

Three, try interesting angles and backgrounds. Consider getting down low on the ground or shooting with the wide angle setting on your lens. Don’t despair if the background behind the flower is unattractive. Try replacing it with a colored piece of paper or fabric. There are lots of different ways you can experiment when photographing flowers!

Spring in the Garden

With all the Millenium hype and the lack of holidays during the first part of this Canadian year, winter has been drearily dragging on and on and on.. But, I know spring is really here when the huge magnolia trees are ready to burst. 

Magnolia stellata (Zone 4-9) has already peaked, but M. kobus (Zone 4-8), and M. soulangiana (Zone 4-9) are just getting ready to do their thing. My favorite of all though, has to be M. grandiflora the Southern or Evergreen Magnolia (Zone 6,7-9). It’s a massive tree growing as tall as 60-80′ and 30-50′ wide. It’s flowers are described as perfect, creamy white, beautifully fragrant and better than the best perfume.

Here in Zone 7 it can be successfully grown in a very sheltered microclimate that may be considered Zone 7 1/2 - 8. In the southern states like Georgia they thrive like our common firs and cedars. How lucky we are in our Zone 7 climate where many of these incredible trees share their beauty, although in a cold winter much damage can be done as we’ve seen in recent years at the botanical gardens. Shelter these babies. 

One thing I can never remember at this time of year is all the planting lore that correlates with the phases of the moon. I want to remember it - it makes so much sense and, hey if the farmers go by it, there must be something to it. Those people make their living from what comes out of the ground, they aren’t growing flowers for fun and decorating. So here it goes. 

The best time to plant annuals (flowers or vegetables) that produce their yield above the ground is during the light of the Moon; that is, between the day the Moon is new to the day it is full. This is also called the waxing of the moon.

An annual is a plant that completes its entire life cycle within one growing season, and has to be seeded each year.. A basic explanation being that at this time the sap of the plant is said to flow upward due to gravitational forces of the moon filling the plant with vitality. 

Plant biennials, perennials, bulb and root plants (potatoes, carrots and beets) during the dark of the Moon; that is, from the day after it is full to the day before it is new again. This is called the waning of the moon. Biennials include crops that are planted one season to winter over and produce crops the next. Perennials, bulb and root plants include all plants that grow from the same root year after year. It is explained in the Farmer’s Almanac that during this period, the plant is oriented toward the root and its sap is rushing downward (also a good time for transplanting).

Interestingly enough, it is believed that the Fourth Quarter (decreasing from half-full to New Moon) is the best time for cultivation, pulling weeds; and destroying pests of all kinds, turning sod, etc. Especially when the moon is one of the barren signs. Now as you read more and more on the topic, you will find all sorts of exceptions to the rule, but the above are the basics. 

Here’s a little ditty that will help you remember when to plant peas.

Sow peasen and beans in the wane of the moon
Who soweth them sooner he soweth too soone
That they with the planet may rest and arise,
And flourish with bearing most plentiful wise.

Thomas Tusser, Farmer & writer Elizabethan era 1558-1603

A very happy gardener am I - Just found a seed packet given to me last fall by gardener extraordinaire Joanne Baskerville who gardens in BC’s interior. In her garden, I spotted some very oddly colored Foxglove in a yummy yellow-apricot. Loving foxglove, but hating pink and purple which is what I’m used to seeing around, I hinted at some seed sharing. Turns out they are a hardy perennial (bonus) by the name of Digitalis lantana x tetra, ‘Johnson’s Tetra.’ A bit late, but better than never, I started these little gems indoors an await germination. I’ll keep you posted on the results.

Now, my neighbor is already on top of his weeding (he’s a rose gardener, can’t you tell!) He came by the other day to say hi (ya sure!) and started eyeing my lovely ‘bed ‘o Weeds.’ “Oh,” he says. “Here it comes,” I thought. “I see you have a lot of the exploding kind. They’re more troublesome than people think,” he says bending down to begin clearing a little area of the culprits. Once again he is correct. Wavy and Hairy Bittercress, also known as Jumping Cress are plants that produce seed whenever the weather is not too cold. We had an extremely mild winter here, so you can guess the population explosion - literally. The seed pods explode up to 80cm from the plant in all directions when touched or ripe enough, disperse potentially hundreds of new little plants. If that isn’t bad enough, when wet, the seeds become sticky and attach themselves to boots and tools spreading them around even further. Forget about Magnolias and Cherry blossoms, when the weeds show their nagging leaves, spring is really here! Indoor Design Tip: The Mini Moss Garden - Use instead of a flower arrangement on your dinner table.

1 Choose a Japanese tea bowl or similar vessel with an Asian feel.

2 Fill bowl with stones almost to the lip of the bowl and add enough water to just cover stones.

3 Cover stones with pieces of moss from shady areas of your garden or nearby park (look in the cracks of concrete that is shaded for most of the day) until you have a mini lawn.

4 From your garden cut one or two small flowers like crocus or vibrant periwinkle

5 Cut two small flowering branches like quince or cherry. Bamboo looks great too.

6 Insert your selected materials into the moss deep enough so that the materials stay in place.

Go as minimalist as you like - a little goes a long way!

February 5, 2000

February Garden Action Items:

There are already many signs of the approaching spring season - make sure you take the time to notice them now, while you are out in the garden - early spring bulbs such as aconites, snowdrops, crocus, iris reticulata will already be peeking through, the lovely scented winter jasmine and witch hazel, and later this month, magnolias and forsythia bloom in this area and the fat buds are almost ready to go!

1. General Clean-up of Beds
February is probably the best time of year for a really thorough garden clean up. Carefully go through all your beds and borders and remove any unwanted plants (weeds or more desirables). Put the weeds on the compost heap, and either move the others to a better location, or share them with your friends. Remove all old vegetation that has died back before it starts to rot, this includes any remaining stems of perennials, piles of leaves, etc.

2. Prune and tidy perennials
Cut back all of last years growth on herbaceous perennials this month, before fresh new growth makes this job much harder and more time-consuming. In milder areas such as the West Coast of Canada and the south of England, this can be done immediately. In cooler areas, wait until the end of this month, so that the old growth can provide that last bit of extra protection from the elements.

3. Winter Mulching
Now that the borders are relatively clear, it is an excellent time to add a thick layer of mulch and/or compost material to them. Carefully sprinkle this material around the plants, taking care not to bury the crowns of perennials too deeply, only add a thin layer over the tops. Several inches spread evenly works best. If you are really careful, the material can be gently forked into the top few inches of the soil, or you can just leave it and it will work its way down during the next few months all by itself.

4.Wildlife in the Garden
Overwintering pests can be removed if you find them now - groups of snails will often hide together in sheltered corners of the garden. Choose your favourite disposal method (try to do better than throwing them over your fence into your neighbours garden - he’ll probably be doing the same thing to you anyway, so you’ll both just end up with a fresh set!). Do be careful not to disturb friendly animals hibernating in these quiet corners, such as hedgehogs in Europe, and racoons in North America. Keep the bird feeders clean and well-stocked, and don’t forget their water sources.

5. Prune deciduous hedges and shrubs
Late winter is an excellent time to rejuvenate deciduous shrubs and hedges with some careful pruning. Remove overly thick branches to let in light and air and encourage fresh, strong growth from the base in spring. Prune for shape as desired, since the outline of the bush is clearly visible.

6. Clean Greenhouses and Cold Frames
Thoroughly scrub out and wash greenhouses and cold frames to prepare them for the early seedlings and cutting soon to be filling them. By keeping them scrupulously clean, you cut down greatly on disease and pests of all manners. Sweep out the corners and wash the glass to let in as much light as possible.

7. Move Snowdrops “in the green”
Much ado is made about this mysterious practice of moving snowdrops in the green, but I think it really boils down to convenience - do it now while you can see them clearly and know where they are!! Lift blooming clumps carefully with a spade and relocate around the garden to spread. If you do not wish them to self-seed, remember to deadhead them once their flowers are over, though why anyone wouldn’t want more of these lovely flowers is beyond me! A real treat is to put a few into a nice container and bring indoors to enjoy - they have a delicate honey-like fragrance that isn’t usually noticeable outside but you can enjoy it on your dining room table or desk. If this takes too long, they also last a surprisingly long time as cut flowers, and make delightful tiny bouquets - put them in a shooter glass or other small container for best effect.

8. Plant bare-root shrubs
Fruit trees, roses and soft fruit can all be planted now. Soak them for a few hours in tepid water if they look really dried out. Plant to the correct level, just above the base of the canes, and add a thick mulch around to protect it from the last cold days and prevent drying out. They should be off to a good start shortly, and provide fruit and flowers in the first year.

9. Layer Rhodos
Some shrubs such as rhododendrons and azaleas respond well to layering and this is an inexpensive way to increase your stock of these expensive plants. Pull downwards a low-growing branch and peg it to the soil. A slight wound on the bottom will encourage rooting. Leave the peg and branch in place until next year, when it can be severed from the parent plant and moved on.

10. Order Seeds
Make sure to get the seed varieties you need for your garden soon - many new or really desirable ones will already be sold out for the season, but no matter, there are lots of lovely plants left. Beginner gardeners should try simple seeds first to gain experience and confidence in the process, and there is absolutely nothing wrong with these basic garden staples!! Almost completely failsafe are annuals such as cosmos, lavatera, baby’s breath, bachelor buttons, sweet alyssum and many more. No matter how good a gardener you are, and how long you’ve been at it, no garden is really complete without these simple comfortable old friends cheering you up.

 

That should be lots of work to keep everyone busy outside, especially since this is a short month. Why not take the “bonus” day of February 29 as a holiday with your family, and spend it in the garden? Either at home, or visit a local Botanical Garden or open estate, and enjoy what early spring has to offer.

Beneficial Insects - Think Before you Squish

by Sharon Hanna


Everyone’s favourite “BI” - the ladybird

For years, well-meaning gardeners routinely maimed, swatted, sprayed and squished every bug they could get their hands on. However careful observation of nature and the move to organic practices have shown that encouraging “good” bugs, or beneficial insects (the politically correct name) is one way to give Mother Nature a hand. She was doing a fine job, however the use of pesticides, combined with overzealous tidiness resulted in loss of normal bio-diversity in our gardens.

Just as when you take antibiotics, and your doctor advises yogurt to normalize the flora within your body, the attraction of beneficials back to your garden can restore balance and harmony in your back yard.

Think before you squish - make this your mantra for the new Millennium. Remember that you may not always know why this creature is climbing the clematis, lurking on the lobelia, or sniffing your snapdragons. 


Everyone’s least favourite garden pest, aphids, seen here smothering rose buds.

It is generally agreed that aphids are “bad”. They spread disease, and cause problems throughout the garden. However, aphids need to be present on your rose bush for a week or two before the beneficial insects will show up. Recent studies show that injured plant tissue sends out distress signals (!) attracting appropriate predators. Be patient, and keep your spray trigger finger occupied with something else, like knitting. 

In general, beneficial insects are attracted to plants from families including compositae (daisy family); the mint family (all kinds of mints, lemon balm, and more); umbelliferae (carrot family, which includes anything which makes an umbel, or umbrella-like shape in the flower head: parsley, fennel, for instance); and the brassica family, a huge family which includes cabbages, cauliflower (all the “stinky when overcooked” vegetables) oriental greens, arugula, radish and more. These produce flowers containing the type of nectar which beneficial insects use as fuel for flight and movement, just as humans use carbohydrates, and “bad” bugs are the protein course.

   
Daisies, mints and cabbages/cauliflowers are among the plants that attract beneficial insects.

Now a look at three common beneficials, and how to attract them to your garden:

1. Beetles. 

You undoubtedly know these large, fast moving, shiny metallic-blue-black beetles! Their full title is predacious ground beetles. I am always dismayed to see one crushed on the sidewalk, the victim of a shoe whose owner may have had good, but misdirected, intentions. 

Beetles are attracted to deep, loose humusy mulch, like the bouncy kind found in the woods, where leaves, coniferous needles, etc., have formed a soft carpet on the ground. They snooze underneath pieces of rotten logs and stones and are nocturnal, dining ravenously after dark upon cutworms, root maggots, and slug eggs, miscellaneous larvae and pupae of undesirables, flea beetles, and leaf hoppers.

To attract more beetles, imitate nature. Along a shady edge, away from foot traffic, dig a ditch three to six inches deep, and a foot wide. Plant mint, or lemon balm, or even red or white clover, along the inside edges to prevent erosion and to provide low ground cover. Drop shovels of peat moss, leaf mulch, coniferous needles, whatever, here and there along the slopes, then place a couple of big, flat rocks in the ditch. The beetles will hide under the rocks in the daytime. Beetles are supposed to be attracted to the nectar of evening primrose.

2. Syrphid Flies AKA “hover flies”.


Hoverflies hover like hummingbirds and perform important pollination and predatory functions in the garden.

So named because they can hover in one place, resemble slender black and yellow bees. Syrphids are important pollinators, but there is another reason to attract them: their larvae prey on many ‘bad’ bugs, but aphids are their favourite. If you look closely you may see eggs on the undersides of leaves near aphid colonies, arranged symmetrically, laid by the female a hundred at a time.

Once hatched, the larvae decimate aphid families in a hurry. The 1/2 inch creature is often mistaken for a “bad” worm or slug, so if you come across a legless, see-through greenish-beige creature, slightly pointy at one end, do not kill him, but wish him ‘bon appetit’!

To attract syrphids, choose plants of the umbelliferae family: fennel, dill, caraway, parsley, coriander, yarrow, or allow carrots to winter over. All produce beautifully symmetrical seed-heads called umbels, attracting a host of beneficials. 

    
Typical umbrella heads of members of the Umbelliferaceae family - this large group includes many vegetables, herbs and ornamental flowers.

Buckwheat, usually planted as a cover crop, can be sporadically seeded anywhere in the garden, and not only does it enrich the soil when turned in, but according to a recent Oregon State University study, is extremely attractive to syrphids. Some people even consume buckwheat “greens” as food - check it out.

They also like cornflowers (bachelor buttons), marigolds, chamomile, coreopsis, and feverfew.

3. Lady Beetles 

Also known as “ladybugs”, they too feed heavily on aphids. If you think about purchasing them, remember… in most cases, the ladybugs go into dormancy or diapause when packaged, and when they are set free their natural instinct is to fly away. Don’t waste your money, instead attract ladybugs by your choices of plant materials. 

   
This unusual creature is a ladybird larvae!!

Become familiar with the ladybug in the larval stage. It looks a bit evil, like an elongated grey-black dragon with many little legs, and orange to red markings. The larvae fix themselves onto leaves, trees, or wood surfaces then pupate for about a week, emerging as the familiar round ladybug of our childhood. 


The more familiar adult stage

All stages of ladybugs from larva to adult feed on aphids. Ladybugs are attracted to cosmos, especially white, and to goldenrod, coreopsis, fennel, yarrow and other umbelliferae. All are easily grown from seed. Lady beetles and other beneficials including the spider (yes, he is beneficial) like to lay their eggs amongst the long grass, so try to leave a strip un-mowed if you can. 

Also it is good manners to provide your insect guests with a drink, in this case water, to wash down the aphids. This can be achieved simply: placing a plastic tray or any kind of pan in your garden and fill it with water. Put rocks in the water for them to stand on.

January Garden Action Items

January Garden Action Items:

As long as you aren’t buried under three feet of snow, there is always a lot of work to do in the garden, so bundle up warmly, put on your wellies and out you go…

1. Hardwood Cuttings
Take hardwood cuttings of your favourite shrubs to increase your stock - just think, they will make great Christmas presents for your friends next year! Follow the detailed instructions on the page “Hardwood Cuttings”

2. Houseplant Care:
Water houseplants sparingly - they are not usually growing as vigorously as during the other seasons and will not require as much water. Do try to keep up the humidity around them though, as indoor winter air can be extremely dry. Stand shallow bowls of warm water around your pots, or stand them on a large plant tray full of pebbles, making sure to keep the water level just below the pot bottom so water isn’t wicked up into the pot and overwaters your plants. Give your houseplants as much strong bright light as possible, but keep them away from cold draughts, and radiators. Never leave a plant on a windowsill between the glass and closed curtains or blinds, it is much too cold. Move them away from the windows at night, and back in the morning.

3. Winter Pruning of Trees and Shrubs:
With the tree framework clearly visible during this time of year, it is much easier to see what pruning is necessary, if any. Remove any damaged or diseased branches first, no matter where they are on a plant, as it would be unhealthy to leave them. Then start to remove more selectively any crossing branches, or any that are badly placed, or going where you don’t want them. Try to have an open, clear centre on a tree, with the main branches growing in an attractive shape outwards. This lets in light and air into the centre of the tree and prevents stale, stagnant air which may harbour disease. Be sure to use the right tool for the job - pruners or a sharp knife for small branches only; loppers and saws where necessary to get a clean, sharp cut.

4. Snow Removal
In areas of significant snowfall (or the wet, heavy type of snow we get in milder areas), it is always a good idea to walk around the garden and where possible, remove any snow from vulnerable plants such as specimen trees and shrubs and the tops of hedges. This prevents branches being weighed down and possibly broken or damaged by the weight of the snow.

5. Clean up and Preparation
Thoroughly clean cold frames and cloches not in use so they will be ready for those early seeds and cuttings. Use hot, soapy water and a good scrub brush and wash both inside and outside of all surfaces to remove grime and any overwintering pests.

6. Soil and Bed Preparation
Put down a layer of compost and/or leaf mould over your borders. Lightly work it in with a fork, being extremely careful around the surface crowns of perennials, and emerging shoots of spring bulbs. You don’t have to dig around too much, the rain and worms will all help to mix the layers together through the year.

7. Moving Shrubs.
This is a good time to move any shrub or small tree that is growing in the wrong spot, or one that has outgrown it’s current position. Prepare the new planting hole well, digging some compost into a hole wider and deeper than the rootball of the plant to be moved. Carefully move the plant, taking care to disturb the soil around the roots as little as possible and place in the new spot at the same depth as before. Firm the soil and stake the tree if necessary. Water in well, and mulch with bark or more compost. If the shrub is very large, prune it back a little to help the roots support it.

8. Plant New Shrubs:
Bare root shrubs such as roses can be planted now, as long as the ground isn’t frozen solid. Follow the directions above for moving shrubs.

9. Bring the Garden Indoors:
Bring pots of spring flowering bulbs indoors now for early blooms. Start to water them a little more and enjoy early snowdrops, daffodils, hyacinths, and more. Another great thing to do is cut some branches from early spring flowering shrubs such as forsythia, cherry, witch hazel, etc to bring indoors. I enjoy doing this even with shrubs that don’t flower, as the fresh new leaves are so beautiful and delicate in themselves. Simply put them in a cool, bright area in a large heavy vase of water, and pretend it is already spring!

10. Order Your Seeds Early
It is time now to order your seed varieties for the upcoming season, especially the new or “hot” varieties for the year, as these sell out very quickly. You should have received a few seed catalogues already, more are probably on their way right now. Always make a point to try at least one or two new ones a year, maybe not the latest and greatest of anything, just something you haven’t got in your garden and always wanted. Check out eSeeds for all your favourite brands, all in one place for convenience and security - we will be adding new varieites non-stop for the next few months, so come back often.
