Q.Calla Lillies
White Calla Lillies have been blooming for many, many years here in Lewiston, Idaho. Planted on north side of house. This year there was leaves but no blossoms. Could it be that they need to be divided or some kind of fertilizer used on them next Spring? Very tall, about 3-4 feet high, beautiful white lilies….but this year, only leaves. Would appreciate very much any helpful info. Eleanor
