That is my question.
I have a container lemon tree that barely survived the transition from my old house to the smallholding a couple of years ago, in fact most of the growth died back and had to be pretty savagely pruned last year just to give it a chance of survival.
I've recently read that lemons won't fruit from suckers and am concerned that the only growth I now have are from suckers but am struggling to identify exactly where the graft line is on the tree.
Can anyone tell me if the bulge identifiable in the attached pic are where the graft occurred? I can't tell as I can't see a clear graft line, just the bulbous growth that I associate from grafting with our apples trees etc.
Thanks for your consideration and hopefully help in advance!
