failure to bloom (calla lily)

Question

I have several calla lilies but one set that I purchased two years ago just doesn’t bloom. I read your advice but nothing. They go dormant all winter and when I plant them (container), they grow beautiful foliage but no flowers. Any suggestions?

Answer 1

Try giving them a boost of phosphorous with bone meal or a "bloom booster" fertilizer. Some varieties of calla lilies (especially those sold as houseplants) are just to finicky be able to get to rebloom in a normal household environment. Keep this in mind and realize that you may just not be able to coax it into bloom.
