How to deal with fungus on crabapples, lilies

by Carol Sitarski Master Gardener, Cornell Cooperative Extension of Allegany County It’s raining, it’s pouring, and the fungal spores may be growing. This spring’s rain seemed to be nonstop. Don’t get me wrong— we needed rain to replenish our water tables, but with the good comes the bad. The bad is all the fungus that may start growing on our susceptible trees and plants. Already I have seen this happening on crabapple trees and Asiatic lilies in my area and…...

Odds may be in our favor for impatiens this year; you can help researchers

by Connie Oswald Stofko What are the odds your impatiens will do well this year? Well, we had a drought last summer, so that’s good. The dry weather inhibited the spread of downy mildew, which is the blight that has been plaguing Impatiens walleriana, the plant that shade gardens had come to know and love for decades. Then again, our spring has been wet and cool, which are conditions that help the disease thrive, said Margery Daughtrey, senior extension associate…...

Stinging nettle: weed or crop?

by Paul Hetzler, Cornell Cooperative Extension of St. Lawrence County If you have a nettle patch, put away the weed killer and consider yourself lucky to have this tasty plant. Many gardeners don’t like stinging nettles (Urtica dioica) because they are painful to touch. The plants sprout little hypodermic needles on their stems, leaves and even flowers. These glass-like silica-based needles, called trichomes, inject a mixture of irritating chemicals upon contact. So why would you risk putting it in your…...

Don’t let your lawn get to this point, dig up lesser celandine now

by Connie Oswald Stofko I’ve been getting emails from people wanting to know what to do with lawns filled with lesser celandine. My best advice is to not let it get that far. Dig it up now. And do it this year when you have only a few patches! This is a serious weed, said Carol Ann Harlos, Master Gardener, garden writer and speaker. “You have two choices,” Harlos said. “You can either spend the time and dig it out…...

Don’t prune oak trees now

While you can prune many kinds of trees in spring and early summer, don’t prune oak trees now.

Oak wilt can kill trees in as little as four to six weeks and is one of the most destructive tree diseases. The video, ‘Winter Pruning For Oak Wilt Prevention’ (two minutes long) highlights why…...
