I live in a zone where the temperature is high 68-70, and low 48-50, every day. 365 days/year. What will the blooming pattern be for the white Calla Lily? Perhaps it will bloom, then take a few. O this, then bloom again?? Hoping to know as the property we just bought has dozens of them. Thanks!
Like many perennials, calla lily have their main bloom period in summer and then revert to being a nice foliage plant. Calla lilies will go dormant in hot, dry weather if not kept watered. To keep yours looking good and for a succession of blooms, fertilize monthly and dead-head blooms as soon as they are past their prime. Do not let them go to seed. This may give you sporadic blooms after the big flush in summer. Calla lilies should be dug up, separated and replanted 6 inches apart every few years. Over-crowding decreases their productiveness. Add compost and / or peat moss to the soil before replanting. On the market are calla lilies with interesting speckled leaves. These are dramatic even when not in bloom.
