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…...

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…...

Prune oak trees now to protect against spreading disease called oak wilt

Pruning oak trees in winter can help protect the oaks from becoming infected with oak wilt, a fungal disease that can be deadly for oaks, according to the New York State Department of Environmental Conservation. The disease was discovered in six new locations in New York State last year and can be spread by beetles that are attracted to freshly cut or injured trees. Benefits of winter pruning: Diseases are rarely spread during this time, since insects and fungi are inactive. A tree’s…...

by Connie Oswald Stofko I saw some beautiful gardens when I was in Atlanta a couple weeks ago to attend the conference of GWA: The Association of Garden Communicators. But since the climate is so different there, I wasn’t sure I would be able to bring back any tips that would help us here in Western New York. Then we went to the home of Lee Dunn and her husband Mike. There I saw something that should interest gardeners who…...

by Connie Oswald Stofko John Jankowski of Batavia sent me a photo that he wanted me to identify, then asked, “Is it a weed or a plant?” Now, usually I’m no help when people want a plant identified. I’m not a gardening expert, so I almost always have to tell people to contact the Cornell Cooperative Extension office in their county. However, I happened to know this one because I have it in my yard. It’s mullein (pronounced mull-en). Is…...
