I noticed the other day that my lemon tree, that is not even a year old, has some shoots/branches growing from down low on the trunk. I did a bit of a search online and found all sorts of negative talk about 'suckers' with very little good said. This is all new to me so I'm still trying to figure this out. It said that suckers are usually branches that come from the root-stock on grafted trees, i.e. below the graft line. My lemon tree is grafted but it seems the branches are sprouting above the graft. Most websites said to get rid of them ASAP as they will surely drain the energy from the main plant. So my query is, are they suckers even though they come from above the graft, and should I get rid of them? I'm keen to let nature do its thing but I'm sure things can be tweaked sometimes to help it out so I'm open to advice from those that know. Besides grafting is probably not found in the wild naturally so its been tweaked already. Any advice?
