It’s not unusual to see strange bumps and growths on tree branches or leaves. Often, insects are to blame.
On this episode of Talk of Iowa, host Charity Nebbe is joined by entomologist Donald Lewis and horticulturist Richard Jauron to learn how galls impact plant health, and for a look at other common insect concerns in the garden. Lewis and Jauron also answer questions from callers.
