Plant Talk 8-7

In this week's plant talk, Kevin helps you out with those pesky problem bugs.
KEVIN: Today we're taking a looking at something called the forest tent caterpillar. Tent, you can see why. The eggs hatch and you get these little larva. The forest tent caterpillar just started feeding, but they protect themselves in this web. This is a little bit smaller one, it probably won't get much bigger than this, but you'll find them on different trees, two, three feet big. One of the best controls? You can just prune out that branch, get rid of it, dispose of it. Spraying chemicals not as effective because that web, it'll protect itself. It's kind of a barrier. You'll also notice there's quite a few ants, and what they're likely doing, they're harvesting the secretions from that webworm.
KEVIN: Now black knot is a fungal disease that attacks chokecherry in our area. It's a fungus (that) creates a canker. Eventually, it'll kill this branch if not pruned out. But you can see, very very gross-looking. We really notice it in the middle of winter, trees can just be infested with it. I don't prune it this time of year because you can spread the disease. Wait 'til winter, go back about a foot, and then prune them out with a sterilized pruner in-between each cut.
KEVIN: Now earlier this summer during the driest part, if you were still watering your lawn but you had dry zones, you probably had sod webworm or some leaf hoppers. They were feeding on your lawn.
KEVIN: It's usually not worth it treating sod webworm or the leaf hoppers. This year it was just amplified from the drought. I hope you enjoyed this week's Plant Talk, we'll see you again next time.
