I’ve looked at dozens of photos online but I just can’t figure it out. Any idea if this is burl or gall? Thank you!
I don’t know, but I get them on my pear.
I get something similar on my espalier apples trained as Belgian fence. Occurs when branches intentionally cross or unintentionally rub on wire. Knobby spurs, no weeping.
Was trunk rubbing on a support?
Thanks for the idea. I don’t see any evidence of rubbing on this tree.
Looks like burr knot to me.
Thanks, everyone! I’ll go with burl/burr knot.
What variety of apple is that ?
It’s my friend’s and she isn’t sure. She was told 5 different varieties of apples were grafted to it.
