Hello all, I have a Morus Nigra tree which is about 5 years old about 2m tall. It doesn't have a central leader but 4 main stems of similar size growing at just above ground height. I would like to grow it into a standard type low spreading tree but feel some apprehension about pruning it as it seems like drastic action....
a) is it safe to take off 3 main stems to turn it into a standard or will it weaken/kill the tree?
b) is it a good time of year to do this? I read that late winter can cause bleeding which can weaken the tree and introduce disease, is this correct?
c) if I leave it as is, will I just end up with a big untidy mulberry bush?
Thanks in advance for your advice!
