Q.White Calla Lilies Did Not Bloom
I planted giant mail order white Calla lilies in containers outdoors this spring. Got great looking foliage but no blooms. Fertilized monthly and kept moist but no lilies. Plants look great and are still growing in an enclosed but unheated patio. I’m about to let them go dormant but how can I ensure blooms next year?

You may have given them too much fertilizer. Fertilizer with too much nitrogen will cause this to happen. This article will help:
