What is a Tree Peony (Paeonia suffruticosa)?
Tree peony, scientifically known as Paeonia suffruticosa, is a woody perennial shrub native to China, where it has been cultivated for more than a thousand years. Belonging to the family Paeoniaceae, it is revered for its stunning, large, and fragrant flowers, which come in a wide array of colors, ranging from whites and pinks to deep purples and reds.

Water
Tree peonies require regular watering, especially during dry spells and the active growing season. They thrive in well-drained soil and should be watered deeply once or twice a week, ensuring the soil stays evenly moist but not waterlogged. However, they are sensitive to overwatering, and so the soil should be allowed to dry slightly in between watering sessions.
Sunlight
Proper sunlight is essential for the healthy growth and abundant flowering of tree peonies. They thrive in full sun to partial shade, requiring at least 6 to 8 hours of sunlight per day. In warmer climates, providing some protection from the intense afternoon sun can be beneficial.
Fertilizer
Applying a balanced, slow-release fertilizer in spring can promote healthy growth and abundant flowering in tree peonies. Opt for a fertilizer with equal proportions of nitrogen, phosphorus, and potassium, which can be applied around the base of the plant and gently worked into the soil. Avoid high-nitrogen fertilizers that may encourage excessive foliage growth at the expense of flowers.
Soil
Tree peonies prefer slightly alkaline, well-drained soil with a pH ranging from 6.5 to 7.5. Amending the soil with organic matter, such as compost or well-aged manure, can improve its texture and fertility, ensuring optimal growing conditions for the plants.
Pruning
Pruning is essential for maintaining the shape, vigor, and flowering potential of tree peonies. It is best to prune them lightly after the blooming period, removing spent flowers and any damaged or diseased branches. Additionally, selective thinning of older stems can encourage new growth and promote better air circulation within the plant, reducing the risk of diseases.
Propagation
Tree peonies can be propagated through various methods, including division, cuttings, and grafting. Division is a common and effective method where the plant is divided into smaller sections, each containing roots and stems. Stem cuttings can also be rooted to produce new plants, while grafting allows the desired cultivar to be attached to a compatible rootstock.
Container Popularity
Tree peonies are also well-suited for container gardening, where they can be showcased on patios, balconies, or other confined spaces. Their attractive flowers and foliage make them an excellent choice for adding a splash of color and elegance to outdoor living areas.
Container Common Diseases
When growing tree peonies in containers, it is essential to be mindful of common diseases such as botrytis blight, powdery mildew, and root rot. Providing proper air circulation around the plant, using well-draining soil, and avoid overwatering can help prevent these diseases.
Disease Diagnosis
Detecting diseases early and accurately is crucial for effectively managing and treating them. Common signs of diseases in tree peonies include wilting, discoloration of leaves, abnormal growths, and presence of mold or mildew. Timely diagnosis can prevent further spread and damage to the plant.
Common Pests
Tree peonies may fall victim to various pests, including aphids, scale insects, and spider mites. Regular inspection of the plant for any signs of pest infestation, such as stippled or discolored leaves, sticky residue, or presence of pests themselves, is crucial for early intervention and pest control.
