Q.Lime Tree Insect Nests
I live in north central Mexico where it’s mostly sunny but gets chilly from November-January. At the first cold, these nests with black egg-looking things started up on the outside leaves of my lime tree. They seem to be spreading. It’s a mature tree, which just in Sept. -Oct. produced a bunch. Should I prune off these branches? Should I spray with something?
