Question From: L. Graham - NEW YORK
Q: I have had sweet woodruff growing for several years under an standard crab apple tree. They’ve always bloomed beautifully but late last after booming they started to look pale and die back. We spayed for insects but this year the plants are flowering but the size of the plants is much smaller. It doesn’t look powdery( like mildew) but they are pale in colour and very small. Any ideas what to try next to treat them? I live in the Toronto, Canada area so I have put in a Buffalo zip for the closest us city.
My guess is a fungal disease. I know that chemical fungicides and herbicides have been outlawed in Canada. I suggest you contact the Toronto Botanical Garden for help. Pictures are always helpful. Best And Happy Yardening, Nancy
