Title: Foam on Salvia greggii in Austin
Answered by: Mike Tomme

QUESTION:

I have 7 Salvia greggii plants. I am seeing a white foam like substance on tip of all of them (where flowers use to be). Any suggestions on what is happening to the plants?

ANSWER:

Sounds like spitllebugs. A spittlebug is an insect that produces a white froth on plants that resembles spittle. Don't worry though, that foam is not actually spit. It comes from the other end of the bug.

The foam serves to hide the bug from predators (including gardeners), protect them from extreme temperatures and prevent them from drying out.

Although they do suck the sap from a plant, most experts agree spittlebugs do not do enough harm to warrant extreme control measures. If you want to get rid of them, a blast of water from the hose usually will do the trick.

Here's a web site with more details: Spittlebugs
