Arum Lily Crowborough
I have several arum lily Crowborough plants in different parts of my garden. Some are in partial shade some full sun. I do mulch them over the winter to protect the crowns. All the plants are healthy and have sent massive leaves this year however I have not had many flowers. Most of the plants have not sent any flowers up at all and even the most established plant has only sent one or two. I have fed all the plants with a general purpose fertilizer or tomato fertilizer and have watered well. Is there anything I can do to encourage more flowers next year. Anybody else had this problem?
