I have potted gardenias that were left outside over a European winter. The leaves are now yellow/brown and very brittle. Is there something I can do to rescue the plants? Should I prune them to remove the dead leaves or should I leave them and just start fertilizing them? Any advice you can provide is much appreciated.
