It’s always sad to watch a prized tree or shrub decay away because of insects or disease. But, if you know what to look for, you can often catch the disease or insect before populations are too high to properly control. Here are 3 tree and shrub culprits to be on the lookout for.
Spider mites – Think you have spider mites? Look for signs of brown, red or purple dots on the underside of leaves. You can also check for a spider-web looking webbing.While spider mites are tiny, if you look closely enough you can see them moving about. When you are sure you’ve identified the culprit, purchase an insecticide to get rid of the mites before they spread.
Bagworms – Bagworms form bags on their hindparts to hide in when disturbed. They target tree leaves, leaving holes in the foliage. The best time to spot bagworms is June through August. When detected early, it’s easier to control. But, when left to their own devices, populations will increase and killing with insecticides can be downright difficult.
Aphids – Neon green, aphids seem to run rampant no matter the garden. These tiny insects are 1/3 to 1/8th an inch making them nearly impossible to spot. While they will munch on just about any part of the plant they can get their hands on, the love new growth best of all. You can spot aphids by searching for stunted or yellowing leaves. Turn the leaves to the underside as this is an aphids favorite lair. To get rid of an aphid infestation, try using an insecticidal soap or wipe the plant with mild soap.
