hmmm, I have a lot of sagebrush, Some will go into hugels, I will have to observe more closely to see how the sagebrush is communicating.

"In the lab version, as the animal's teeth ripped the sage leaves, scientists watched the sage plant send a chemical signal into the air, and watched as a nearby tobacco plant picked up the signal and then emitted an odor that was noxious to the animal — strong enough to repel the antelope — protecting itself, and, arguably, helping the sage."

This is very interesting! Perhaps with the right combination of plants we could build a chain reaction garden defense system!
