Strange growth from my blueberry bush
I bought several blueberry bushes earlier this year and one of them has a rather strange growth on the side of it. The stems are growing significantly bigger and faster than the blueberry bush itself, although the growth does appear to be coming from the blueberry plant. I have no idea whether the blueberry plant was grafted but I’m suspecting it was and that growth could be from the rootstock. Any advice on what’s going on and how to deal with it would be much appreciated. Thanks in advance for any help.
