Cobweb like growth on Cherry Trees

Asked August 15, 2019, 9:30 AM EDT


We have a new Cherry Tree, planted this spring, that suddenly, and in a span of 2 days, seems to have become infected with something that has caused an extensive cobweb/cotton like coverin on two of its branches. some leaves also have holes and brown spots and a couple have their brown edges tightly curled. Please advise us on how to treat this. Thanks.

Hi - The webs you see on your new cherry tree are produced by fall webworms. There are two generations of these insects each year in Maryland and their populations fluctuate from year to year. This year, we're seeing them in high numbers. They are a native insect and have many natural predators. You can take a brush or broom or gloved hands and break open the webs and physically remove as much as possible. This will expose them to birds (predators). They will not sting you or harm you in any way. They are mainly a cosmetic nuisance. Here is more information about them.
