What did survive into spring, 2011 were rhododendrons, azaleas (Northern Lites Series), many funky (+20 varieties) ferns, 3 varieties of Smoke Bush, a Contorted Hazelnut, and many Japanese Tree Peonies. A new Pagoda dogwood did fine, as did many other things that technically have trouble wintering here. And who says
we can't have perennial "Exotics" in Winnipeg. This (left) is a Rogersia, one of 3 varieties, and with the right light,
it can become as big as many plants you'd see in Vancouver. Go shopping early, see what's out there, then go
home and GOOGLE it. Whatever didn't do well in dry shade, reconsider; there's as good a chance as any this
is the weather we can look forward to and if they couldn't take it this year, do you want to fuss over them next?
Some past favourite and frequently recommended plants have been dropped from a list due to their inability to
tolerate the heat and wind; what if this is what summer is from here on in (as if anyone can truly predict)? The
weather took its toll on a lot of plants, trees and shrubs and some of the more hardy, devil-may-car survivors
were almost inexplicable. That said, it's a new game out there, and the more information we have, the more
help we can give our gardens, without becoming slaves to them and the happier we will be with what these gardens
give back to us. Diseases are becoming more prevalent and we need to understand what we can do to help
recognize the early signs so that we are able to help the plants along, perhaps even save them. This fall, my
garden is under-going a much needed soil amendment as well as an edit as I have realize it is more work
now than pleasure and that's NOT what it, or my business is all about. Nature, as always, wins and I shall work
with her if I wish to remain a happy gardener! From Mike Allen, re spruce trees, water, water, water; you'll
extend their lives but ... reaction to climatic extremes is not the only factor involved with spruce needle
discolouration. Nearly all spruce trees in southern Manitoba 15 years and older have a slowly lethal fungal
canker disease called Cytospora. I refer to it as the white blister disease. It is an indigenous disease to Manitoba
white spruce. The other diseases also contribute to the needle browning situation. Cytospora disease displays
several forms on the tree as signs of infection. There is no known cure for this fungus canker disease which is
the most common and most widely spread disease of ornamental spruce trees in southern Manitoba; Google
for further information. We are being faced with several diseases that ultimately kill the host tree so it's
imperative we take the time, particularly at this time of year, to add slow release fertilizer to the roots of our
trees and shrubs, amend the soil with compost (Samborski) and to add iron chelate to any woody perennials
that had yellowing leaves during the summer.
We can't change what nature does but we can help to slow down the course of these diseases and recognized
that, at some point, in order to save others (Dutch Elm Disease, Black Knot disease, Fireblight) from infection,
we should remove our sick plants and bring in newer hybrids less prone to disease. Just remember many
diseases have come as a result of hybridization so there's no guarantee we aren't fighting a losing battle be we
also cannot leave the land barren; without trees and the oxygen they create, there is NO life for any of us.
