Q. I live in the desert southwest and my rosemary plants have a white liquid substance on them. It looks like cotton, but it is liquid. What can I do?
A. It sounds like Spittlebug on your rosemary, but being from the Mid-West I was not sure what it’s cycle was in the desert area. I found the website below that shows pictures that you can compare. Check with your local garden center for control in your area.
