Rhododendron needs some help and advice!
I have had a few rhododendrons for a couple of years and they have generally done fairly well. I am afraid that the harsh winter that we had in Ontario this year might have done some pretty severe damage to them though. The leaves are pale, slightly wilted and have fairly significant brown spots on them. I do see the start of a few new blooms though, so I'm taking that as an encouraging sign. If anyone has some advise about how to treat them and encourage healthy growth and blooms, that would be much appreciated. I am a pretty 'beginner' gardener, but keen to learn. I have used bone meal, but am thinking maybe I need to fertilize and perhaps increase watering??
Thank you, Jessica
