Culley joined the monthly gardening show to discuss fall tree care and the latest scourge of backyard gardeners.
Culley said none of the three common species of boxwoods are native to the United States.
Culley said boxwood leaves can yellow and curl when they begin to fall prey to caterpillars. And gardeners might even see some of the wispy silk webbing from the caterpillars.
“When you apply pesticides, you only want to do it if you see an infestation,“ she said. “You don’t want to preemptively spray. It can do more damage than good, especially to the mites that are beneficial to the boxwoods.“
Culley was joined on the program by Jon Butcher from Madison Tree Care and Landscaping and Dominique Peebles, owner of Brick Gardens.
