I have two smallish potted Magnolias on my balcony and I pruned them both a few months ago. Only one has lost it's way - it's leaves are all dying and dropping off and the other is as strong as can be!! What should I do?
Plus I have a smallish potted Camillia on my balcony that used to be fine but I had to repot it recently and now all the leaves are brown and dropping off. Again what should I do?
