View Full Version : What's growing on my tree?

I have very strange broccoli looking things growing on my ash tree. (see photo)

What are they? Are they good or bad? They're really weighing down the branches.

This is our third year in the house and the first time they've appeared.

Thanks for the help.

If I'm seeing that picture right, I think it's from the ash flower gall mite, Eriophyes (=Aceria) fraxiniflora. Very common, and not harmful to the tree. See this link: http://www.forestpests.org/ash/ashflowergall.html
