Question From: C. Reid - HAWAII
Q: Something is causing a sort of blistering, malformation on several hibiscus plants in my garden. I treat with an organic insecticide, but it doesn't seem to help. Any advice?

They look like some sort of gall or scale. Take samples to a good independent garden center or nursery for a more accurate Id and method on control. I've never seen anything like that here in Michigan, so I can't recommend a control. Best And Happy Yardening, Nancy
