How to prevent and control peony root rot? Where should prevention and control begin? We ask fellow gardeners for guidanceCauses of peony root rot:
The peony has deep-growing fleshy roots and fears prolonged waterlogging. It should not be watered too much at ordinary times and should be kept suitably on the dry side.
Peonies prefer high, dry spots with well-drained soil. Fleshy taproots and lateral roots. The primary roots are initially white. The fleshy parts already store a large amount of nutrients and water for the plant's growth. Once water accumulates, it will cause root rot.
Prevention and control methods for peony root rot:
1. Watering and fertilizing should be timely and appropriate:
Since the peony has fleshy roots and fears waterlogging, it is not easy to water it much, and even less advisable to water it heavily; it especially fears water accumulation, otherwise it is prone to root rot and leaf drop. Reasonable watering should be "water when dry, stop when wet." Fertilizing should also not be excessive. In addition to applying base fertilizer, a dilute liquid fertilizer can be applied about once every 2 months; during the dog days, apply a dry fertilizer once; at the flowering stage, add one application of bone meal and phosphate fertilizer.
2. Use a loose, fertile, well-aerated potting soil. Prevent water from accumulating in the pot.
3. Prune in time. Peonies should undergo one shaping pruning after the flowers fade. Too many branches and too many flower buds consume a large amount of nutrients and affect flowering the following year; even if they can bloom, the buds are prone to dropping.
4. Do not move them outdoors too early. If potted peonies are moved outdoors too early in early spring and suddenly encounter cold air or a cold snap, the flower buds are prone to yellowing and dropping.
