Hello. I purchased a pot of blooming Calla Lilies 3 years ago which had short leaves and small light purple blooms. Since they initially stopped blooming I dried the soil over the winter and then in the spring
re-potted them all together. the next year they grew very long leaves but no blooms. Then last year it was the same, very very long leaves (like over 18 inches). So this year when I re-potted them in the spring
I broke up the colony of bulbs and re-potted them in several pots and they began growing
again initially with short leaves but now they are getting very long again and I really want them to bloom as they were so pretty before. Does anyone have any suggestions? They are in a large sunny window facing south and potted in Miracle Grow potting soil. Thanks.
