Why Don’t My Iris Plants Flower?

Question

My irises have great green leaves but hardly any blooms! I did put some bone meal and lime on. How much or what else can I do? We live in Zone 7.

Answer 1

The most common reason for irises failing to bloom is overcrowding. Dividing and transplanting them usually helps. In addition, it can be attributed to poor pollination. Try to entice pollinators (bees, butterflies, etc.) to the area with brightly colored flowers.
