Plant your peonies about 1 ½ to 2 inches beneath the surface for best results. One of the causes of peonies not flowering is that gardeners put them too far below ground level. Cover your peonies each fall with a topping of compost to enhance the health of your peonies.
Locate your peonies in medium-moisture soils. These are drought-tolerant perennials once they establish themselves. The soil should be well-draining. Peonies grow best when the pH levels of the soil in which you plant them are neutral.
Place peonies in partial shade. Peonies grow in full sunshine, but by situating them in partial shade, where they gain some protection from afternoon sun, you prolong the life of their delicate flowers. Too much shade however will cause peonies to produce no flowers.
Remove the spent flowers from your peonies to prevent the seedpods of the peony from forming. Cut your peonies to the ground after the first autumn frost occurs.
