The Q&A Archives: worms on my gazanias

Question: About 3 weeks ago I planted some gazanias. They were doing great until about a week ago when I noticed some of the leaves had greyish areas on them. Today I notice they have worms on the flowers and some of the flowers are partially eaten. The worms are dark color with light color stripes and about a quarter of an inch (or less) long. I grew gazanias in S. C. and had no problems with them. How do I get rid of them? Prefer not to use chemicals.

Answer: Marge,

I suggest you spray them with a product containing B.t. which is a natural organism that kills caterpillars but doesn't harm other insects or people. B.t. is sold in many brand names including thuricide, dipel and bioworm killer.

Thanks for the question. Please stop in again soon!
