Poorly Gloriosa Lily
I have two gloriosa lily tubers planted in a terracotta pot in the greenhouse. They started sprouting nicely but I've noticed that some of the leaves are turning brown very quickly. I had the same problem last year. According to the instructions I received when I bought them, they need to be in as sunny a spot as possible (which they are), and they should only be watered when the compost has dried out completely. However I have read now that they should be kept moist and fed weekly. Can anybody tell me where I'm going wrong please?
