All my lavender bushes are covered with something that looks like somebody spat on them.

Its cuckoo spit which is a little green insect that produces this froth to hide. rub it off or give a blast with water to remove. I have it on my lavender too, but it doesnt seem to cause too much problem

I think the little green bug inside is called a froghopper. From what I gather, they do no harm to the plant and the froth is to protect them from the birds and other beasties that like eating little insects.

I also have this on my wild rose, thought one of my kids had been spitting out the windows hehe

bless them good thing I never shouted at them

Thank you all so much. I've never had anything like this on my plants. I am glad to find it's nothing to worry about.

Just checked my lavenders and they're covered in it! Yuk! All sticky!
