It seems it was rather windy here last night, and I woke up to find a large branch has broken off my beautiful deciduous magnolia. I would say it accounts for about 1/5 of the overall tree, and it looks like it has split quite far down the main trunk. It looks a bit lopsided now, but there is still plenty of tree left for it to look ok!
Anyway, I'm just worrying if this may cause the tree problems, particularly with a large wound now on the main trunk. It's there anything I can do to help it? I thought I could perhaps prune the rest to even it up, but I read that they don't respond well to pruning.
