Q • My peony makes lush, green leaves, but why doesn’t it bloom?
A • There are many possible reasons why your peony isn’t blooming, but here are a few of the most commonly encountered issues.
First, your plant may not be receiving enough light. Peonies require at least six hours of direct sunlight to bloom well. Place them in an area that receives full sun in the morning and shade in the afternoon to protect the flowers from fading. Relocating peonies should be done in the fall.
Second, planting peonies too deep will hinder blooming. The crown of the plant should not be planted more than 2 inches below the soil line.
Lastly, if you divided or transplanted your peony within the last year or so, it may take 2 to 3 years before it blooms. The plant requires a lot of time to reestablish its root system and build up enough energy to flower.
