Zig Zag Sawfly adults have been trapped this week emerging in Central Ohio.

Box Tree Moth (BTM) (Cydalima perspectalis, family Crambidae) is in the news prompting home gardeners to ask questions about treatments. Infestations have only been found in S.W. Ohio and boxwoods should only be treated if infested. This Alert provides a list of insecticides.

The Lorain County Public Library system hosted four workshops for patrons on houseplants. The program just began to scratch the surface on Houseplants. This area of Horticulture is in a world of its own, mostly ‘Tropical’.

Box tree moth (BTM) caterpillars in southwest Ohio have awakened from their winter slumber meaning Ohio’s BTM hunting season is now open. There is no bag limit. This means it's time to take a close look at boxwoods to find, report, and manage BTM.

Springtime temperatures keep the biological calendar moving right along. While the progression of blooms and the activity of insects aren't tied to specific dates on the calendar, but rather, it is a sequence of activity that aligns in the same order year after year. 

In honor of the Biggest Week in American Birding, out next webinar is all about birds, the foods they eat, and the impacts of pesticides.

Boxwoods (Buxus spp.) in Ohio continue to be “in the news” this season as a result of the carry-over of several challenges experienced last season. Those challenges have caused some to question the continued reliance on a long-reliable plant. However, is rejecting boxwoods based on perception or reality?

Many of our BYGL readers, like yourself, are interested in the health of our forests, whether that be large expansive woodlands, or individual plants in urban areas. We were recently contacted by Anna Funk and Rachel Kappler with Holden Arboretum and the Great Lakes Basin Forest Health Collaborative. Below you will find information written by Anna and Rachel to introduce you, in a Q and A approach, to the collaborative and most importantly what you can do to help.
