What’s Bugging You
"Ugly" "disgusting" "gross" and "creepy" are just a few things gardeners say when they see tent caterpillars. Not only are they visually unattractive, but the hundreds of caterpillars within a tent can defoliate a shrub or tree in a matter of days. Fortunately, the attack is seldom fatal.
One of the most common and easy to recognize plant diseases, powdery mildew, is caused by fungus spores that overwinter in garden debris and are spread by wind the following season. In late spring and early summer, the warmer days and high humidity provide perfect conditions for spore germination.
