Peony flowers grow best in direct, full sunlight. Grow them where they will receive bright, direct sunlight all day long.
Tree peony species grow well in dappled sunlight.
Too little sunlight results in fewer and smaller flowers. And, low light levels make the plant more susceptible to disease.
Peony plants are grown from roots. The roots develop “eyes” which in turn grow into a new Peony.
When transplanting roots from an existing plant, make sure there are at least a couple of eyes on the roots.
Peonies plants like rich, well-drained soil, and full sun. Add plenty of compost and well-rotted manure before planting, and again each fall.
Plant roots with eyes 1″-2″ deep. Space plants a minimum of 24″-36″ apart.
The plants grow fairly quickly to their full height. The flowers bloom in the spring to late fall. Make sure to provide water during periods of drought.
Add a general-purpose fertilizer a couple of times a year. Also, use fertilizer high in Phosphorus about two weeks before blooming.
Peonies produce a thick, lush plant. If the plant appears too bushy, trim, and thin to improve air circulation. This will help to avoid plant diseases that can harbor in the dark, humid areas of this dense plant.
Garden Tip: If the plants are too bushy, it could be a sign of too much nitrogen in the soil. Consequently, cut back on this fertilizer, and substitute with one higher in Phosphorous.
The profusion of leaves and flowers can cause the plants to fall over, spoiling the beauty of the bloom. Make sure to support the plants with garden stakes or hoops.
In the fall, trim the plant back. If it has experienced plant disease, you can trim it back to the ground. Remove and dispose of any diseased leaves and stems.
Add a covering of mulch in the fall in areas where there is little or no snow cover.
After a few years, the clumps of roots can get too thick and may require digging them up and removing some of the roots. A sure sign of the need for thinning the roots is smaller flower blooms. Chances are, your friends will appreciate your delivery of roots from your favorite plants.

Pruning helps to keep your plant healthy and attractive.
First, remove dead, damaged, or diseased leaves and stems.
You can trim the shrub at any time to keep it in a shapely form. However, be careful not to cut off emerging flower buds.
If the foliage is dense, thin the plant out a little. This improves air circulation and helps to prevent plant disease.
As soon as the flowers have died, remove them from the shrub. To deadhead the blooms, use a pruning shear. Remove the flower stem where it meets the stem of the plant. Deadheading spent blooms kept the shrub attractive, and the plant sends more energy to store in the roots for next year’s growth.
If you plan on harvesting seeds to grow new peonies, leave a couple of spent blooms on the plant.

Peonies shrubs usually have few insect problems. The presence of ants is common. They are attracted to the nectar in the sweet flower buds. Ants do not hurt the plant or the blooms.
