PRESIDENT'S MESSAGE

Spring is in the ….aisles!

With 80 mph winds and below zero temperatures, I crossed the parking lot into Costco recently.

There it was! SPRING! I had been hoping to find it sprouting in my garden, with the greening and firming of my lawn or with the warmer air around me, but here it was! The aisles were filled with outdoor furniture, gardening tools, pots, grass seed and décor! Does grass seed even work in March?! Should I hurry up and buy it now. At this rate it could soon be replaced with Christmas items! I know Spring is coming, I love living in a part of the world where I can watch, delight and savour the changes each new season brings.

The Gardening Community is brimming with activities and events to inspire and educate you, as we get closer to time in our gardens. Please peruse and consider attending one of the events we have listed in our Greenleaf and listen for a special announcement we will be making at our meeting on Monday!

See you at the meeting!  Robin

The Plant Sale is the Oshawa Garden Club’s major fund raiser and planning for 2017  is now underway. Funds from this sale, allow us to continue the Club’s activities. We are pleased to continue partnering with G.L. Roberts Collegiate, Peter Keeping (Clematis), Robert Young (Dahlias) and the Master Gardeners. 

Once again, we will be asking for plant donations in early May. Please keep us in mind as you open up your gardens. This year we would like to expand our plant selection to include vegetables. If you grow your own veggie plants (tomatoes, peppers, radishes, onions etc.) please consider donating some to the sale. Your support has made the Plant Sale a success in the past. Let’s work together to make this year’s sale the best ever.

MONARCHY BUTTERFLY UPDATE 

www.davidsuzuki.org
Since the 1990s, the eastern monarch population has declined by about 90 per cent. More than a billion monarchs once made the journey to Mexico. That number dropped to 35 million in the winter of 2013. Last March, an intense late-winter storm wiped out more than six million monarchs. Also last year, poor weather, during critical breeding periods, resulted in a 27 per cent reduction in population.

Canada's Minister of Environment and Climate Change, Catherine McKenna, visited the winter home of North America's butterflies in Mexico. Read her interesting story at this link www.thestar.com/opinion/commentary/2017/02/09/committed-to-protecting-the-magnificent-monarch-butterfly-mckenna.html


PLANT HARDINESS ZONES

















Last month our speaker gave a talk on information for gardeners, as we adapt to climate change. One area of change is plant hardiness zones. In Canada, most areas along the U.S. border are at least a half a zone higher now and changes in western Canada are more pronounced.
http://www.planthardiness.gc.ca/?m=22&lang=en.

TREES
Garden Club member John P sent a question: What can be done about the many insects and blights that are attacking Canadian trees?















Last month Mary Olaveson mentioned that climate change and invasive species are changing the gardening landscape. For example, the mountain pine beetle devastation in British Columbia is blamed on climate change, as the winters were not cold enough to keep the beetles in check. The emerald ash borer in Ontario is an invasive species brought here on wood shipped from Asia. Cedar leafminer damage (above) is an easy fix and can usually be halted by pruning the damaged branches early in the spring, but the solutions for these problems are not always easy. We now understand that there are health issues and environmental harms caused by pesticide use. Specialized knowledge is often required to understand the many rules, regulations and precautions that are necessary before using these products. The best practice may be to call a professional arborist. The Saugeen Valley Conservation Foundation has a webpage listing problems and solutions for some Ontario trees. 
Appendix C contains information about pesticide use.

THE BALANCE OF NATURE
A land without insects may sound like a gardener's dream, but because so many animals depend on insect protein for food, a land without insects is a land without most higher forms of life. 
Spiders make up half the diet that a mother wren feeds her babies. Birds that can fly but prefer life on the ground feed their young insects. Mr. Tallamy hopes that if we understand the role insects play, we won't feel compelled to squash them and hopefully we will stop spraying them.
Doug Tallamy studies insects and is the author of Bringing Nature Home.

Imagination Station Vida

March's Theme: Celebrate Spring!
Create a design that celebrates an image of Spring using plant material. Remember that vegetables and fruits are plant material. For example, you might create a shamrock using a leafy vegetable. You might create an Easter bunny using a piece of fruit for it's body. Accessories may be included sparingly. The majority of the design should be plant material. Spring flowers such as daffodils or tulips, red and white colours for National Commonwealth Day.

Ideas: Celebrate St. Patrick's Day, the first day of spring or even National Commonwealth Day (13th) You might consider floral/plant arrangements that include: a pot of gold, a rainbow of colours, a leprechaun's outfit - hat or boots or belt, a shamrock, a mug of beer.


April's Theme: Celebrating and commemorating...
Create a design commemorating one of these special days using plant material.
April Fool's Day (1st)
Easter (16th)
Passover
Bat Appreciation Day (17th )
National Garlic Day (19th)
Vimy Ridge Day (9th)

Participate!
Have fun with this. We are no longer voting for our favourite entry. Every participant will receive points for entries. Submit as many creations as you wish. Every meeting, one of the participants will receive a bonus point as a result of a random draw. Working with plant materials and feeling creative can be very rewarding. Start with small, simple arrangements until you find your comfort zone.

For inspiration, attend the District 17 meeting and watch Lizzie Matheson create large, stunning floral arrangements...all the while telling hilarious stories...mostly about hiding her garden purchases from her husband!

GREEN LEAFY THOUGHTS!
Everything You Ever Wanted to Know About Hostas

Brother Stefan 2017
Hostas are considered an easy to grow plant. They are resilient, cold hardy, good for beginners and often recommended when a shade plant is needed.
  • There are more than 7000 named hostas
  • Clay soil that forms a bowl and then receives too much water will drown your plants  
  • Hostas prefer slightly acidic soil 
  • Leaf yellowing  might be caused by incorrect soil  PH
  • Herbicide sprayed on your lawn or your neighbour's lawn could damage your plants 
  • Consider wind protection when you are planting your hostas
  • Hostas like organic materials (compost, well-rotted manure) added to the soil. It is usually recommended to give them a balanced fertilizer such as 20-20-20, just as the growing season is starting and again   6-weeks later 
  • Do not fertilize after July 31
  • Water close to the roots, especially if the hosta leaves are large and form an umbrella preventing the rain from reaching the roots 
  • If your hostas are competing with tree roots for water, consider planting them in a paper pot with a drainage hole and bury it in the garden
  • Hostas are tough, but if we have a winter with a lack of snow cover, protect them with leaves or straw
  • Hostas like an average of 6 hours of shade per day 
  • Solid green and blue hostas will grow in full shade, but hostas prefer some sun 
  • Dappled sun, early morning or late afternoon sun is best 
  • Green-yellow, and yellow centred hostas look best with 2-hours of direct sun
  • Mid-day sun can be too much for some hostas 
  • Sun is required to produce outstanding blossoms. The flowers vary in colour from white to deep purple. They can be bell shaped or funnel shaped
  • Fragrant hostas use sun to develop fragrance 
  • Hostas receiving more sun than desired might be saved by keeping the plant well watered 
  • Faded spots on leaves, brown leaf tips and brown edges are signs of sunburn
  • It is natural to see hosta leaves change colour as part of their annual growth 
  • Grey and blue hostas have a gene that creates extra crystalline wax on the top and/or bottom of the leaf. This can melt off in direct sun or high winds. If a  thunderstorm removes this wax, the leaves will be green until the next season.
  • Hostas take 5-6 years to mature. The bluest blue hosta colour comes with the plant's maturity.
  • Some hostas have very corrugated/textured leaves. These are often sturdy plants that are able to withstand a harsh winter. Rugose is the scientific term for corrugated leaves and comes from the latin word for wrinkles.
  • Hostas grow well in containers. Use a container with a drainage hole and a good potting mix and a slow release fertilizer. Keep your containers watered. 
  • You can treat your container hostas like annuals or you can overwinter them by burying the plants in the ground or place the container in an unheated shed and water lightly throughout the winter. Freezing is not a problem, but the freeze thaw cycle is not good. 
  • Basic hosta colours are green, blue, yellow. There are no white hostas, although white can be found in the centre or margins of the leaf. Plants use green pigmentation to create chlorophyll. Chlorophyll is vital for photosynthesis. This means that all white hostas must either develop green tissue or die. There are some hostas that emerge entirely white, but will later develop green tissue as the season progresses. White hostas have thinner leaves that are susceptible to sunburn and melting out. They are also slower growing.
White Feather













  • growing hostas can be very addicting and many theme gardens are created with hosta names. For example, a sewing theme might include H. Crazy Quilt, H. Corduroy, H. Zipper and many many more. See www.hostalists.org for more ideas.
  • Removing hosta flowers seems to be a matter of personal preference. Some people prefer the foliage and trim the flowers. Others enjoy the flowers and keep them for the pollinators.
  • Diatomaceous Earth is a naturally occurring, non-toxic material that has been used to deter slugs when sprinkled on the soil around your hosta plant. Slugs prefer wet conditions and diatomaceous earth does not work well in wet conditions. This product will also harm beneficial insects and bees, therefore it cannot be recommended.
  • Experts say that egg shells are not effective
  • Best practice is to plant thick leaved / slug-proof hostas. Clean up your hosta garden in the fall to prevent overwintering of slug eggs. Count on your local birds and garter snakes...yes, garter snakes love to dine out on slugs!
  • Consider accepting less than perfect in your garden and be proud that you are promoting the balance of nature
  • There are pros and cons to using mulch, but avoid large bark pieces, as slugs love to hide here. Keep mulch away from the base of your hosta.
  • Hosta Virus X is one of seven viruses that hostas are susceptible to. Hosta Virusa X is spread by sap, so best practice is to wipe your pruning blades with a chlorox wipe, before moving to the next plant. The virus causes "bleeding along the veins" and is sometimes difficult to identify, but pictures can be found on the internet. 
  • Hosta Virus X test strips can be ordered from www.Agdia.com and are easy to use. Diseased plants must be dug up and placed in the garbage
  • True-to-name hostas and hostas grown to quality size can be an investment, therefore new introductions to your collection should be purchased from reputable dealers.
  • If your hosta out grows the space, you can move it or divide it, but best results are obtained by leaving your plant undisturbed and allowing it to grow
  • Hosta information is endless! 
GOLDENBROOK HOSTAS
14950 Reginal Road 57, Blackstock
After ten plus years, Cindy and Carl, specialized hosta growers, are downsizing and retiring from their business.
