Does anyone know whether it would be ok to prune a magnolia now ? It is one of the soulangeana type, and is very large (about 20ft). We need to prune it because it is interfering with the overhead telephone line that leads into the house, and thought now would be a good time - there are no leaves so we will be able to see what we are doing better. But thought I would check here before the pruning saws come out.
And if now is a bad time, when would be best?
