Question From: L. Laxon - MAINE
Q: I have a four year old potted rosemary plant that is suddenly not doing very well. Some small spider web-like clumps are appearing, as if little critters are making a home for themselves by 'webbing in' three or four leaves. I found a tiny caterpillar in one of the clumps. I live in Maine and my rosemary spends summers outdoors, so lack of light or stagnant air do not seem to be a problem. In an effort to help the plant, I just repotted it and did some significant pruning, but I think the pests are the issue. Do you know what these pests might be and how to get rid of them?
A:
You probably have spider mites. Not sure about the caterpillar. Bonide's Captain Jack's Dead Bug Brew will take care of both. The active ingredient is Spinosad, a beneficial bacteria. It is safe for use on edibles. Reapply three times at 7 day intervals. I give my Rosemary a shower every couple weeks in winter-time. Best and Happy Yardening, Nancy
