Mulch for Mycorrhizae

July 27, 2017

Mulches suppress weed growth while retaining moisture in the soil for tree roots and microbes, so they are excellent for minimizing soil disturbance and thus supporting the mycorrhizal fungi that associate with plant roots. Read about these fascinating connections in C.J. Walke's article "Building the Mycorrhizal Connection" in the summer issue of The Maine Organic Farmer & Gardener.


Watch for Apple Borers

June 29, 2017

Check young apple trees for signs of the round-headed apple borer now. Here's what C.J. Walke, MOFGA's organic orchard specialist, says about this pest: "The adult makes a small slit in the bark of the trunk at the soil surface and deposits an egg in the slit. As the larva develops, it eats the cambium layer just under the bark; you can see its moist, orange/brown, sawdust-like frass coming from the hole in the bark where the egg was laid. (Frass is the waste that larvae excrete after eating plant tissue.) The larva lives for two or three years in the tree, creating roughly a dime-sized cavity in the first year, but excavates around the tree, even into the roots, the following two years, severely weakening or killing the tree."
