tree peony

Tree peony (Paeonia suffruticosa 'Lilith') prefers moist soil, but be careful not to overwater. Water during the establishment phase (first year or 2) once every week or 2. Thereafter, water only when the soil feels dry, about once a week. In warmer climates, additional watering may be needed during summer months. Apply enough water to moisten the soil to a depth of at least 10–15cm (4–6 inches). Avoid wetting the foliage, since this can lead to disease problems and discolouration. Apply a thick layer of mulch around the plant to help maintain soil moisture.

Tree peony (Paeonia suffruticosa 'Lilith') should be grown in full sun for best flowering and foliage growth. This species prefers at least 6-8 hours of sunlight per day if possible. In cooler climates, partial shade is acceptable, but the plant should be given the most direct sun possible to ensure good flowering. It is best to provide sun exposure in the morning or in the early afternoon with some protection against the strong afternoon sun.

Tree peonies should be pruned in early spring before new growth begins. Pruning should be kept light since it can take many years for the plant to fully bloom. Remove any weak or damaged branches and deadwood. If the shrub appears to be overcrowded, lightly thin out branches on the inside so that the center of the plant is open. Any branches that cross over each other should also be removed. Additionally, cut any branches that stick out at odd angles. This will help maintain an attractive shape and promote healthy growth.
