Question From: T. Velasquez - California, United States
Q: We have a grown, large rosemary bush in our garden. I just noticed that there is a "wet, milky, frothy type substance" all over the bush, even under it. What could this be, and is this poisonous???
A: Your rosemary has spit bugs. The "spit" protects them from predators. Hose off the plants with a strong stream of water. If you want to harvest it within a few days, soak the branches in water. Not to worry, there is nothing poisonous. Best And Happy Yardening, Nancy
