:) Hi everyone,
:) I'm a new member, and this is my first post, so excuse me if I break any
:) "rules". :)
:) My husband was out in the front yard earlier today and came in to tell me
:) that something was growing on one of our two Oak trees. They don't look

It's a type of gall. Usually they are made by tiny wasps that sting the
plant tissue or various flies that injects liquid into the plant tissue

made also from beetles , moths, aphids and thrips on different plants
along with bacteria, viruses , mites and fungi.
