Galls on Quercus robur

Post  Ingvar Nilsson on Mon May 27, 2013 2:11 pm

Hi,
This spring I dug a Quercus robur oak from another location and now some 4-5 weeks later it has a big outbreak of galls on the leaves. There is a tiny larva inside each gall. The big oaks in the ground nearby my yard doesn't seem to have them (at least not this many). The tree seems healthy except for the galls, but being newly collected I know they are susceptible of catching everything unpleasant.

First: Is the galls (in general, not knowing exactly what insect this is) harmful to the tree?
Second: Would it be best to fight this with systemic poison or cutting off the galls? Or not at all?

Hi Ingvar

Remove the galls, and destroy them....no need to bring them to your garden.

Kind regards Yvonne

Hi Yvonne,
Mange tak! I took off as many as I could find and squished them. It was more than a hundred! I'll check again in a week to see if there is more.
