How to remedy peony root rot

1. Reduce watering

Reason: Peony has fleshy roots and is afraid of waterlogging, so don't water it too much, let alone too much water. Once water accumulates in the potting soil, it will easily cause root rot.

Solution: Water reasonably, wait until the soil is dry before watering, do not water too much or too frequently. In addition, during the rainy season, pay attention to proper shelter from rain and take drainage measures in time.

2. Prevention and treatment of root rot

Reason: If pathogens or nematodes invade through the wounds of the peony, it will easily cause harm to the already injured roots. Root rot will cause the roots to turn black and rot, affecting its normal growth.

Solution: After discovery, the diseased roots should be cut off in time and disinfected. In addition, appropriate fertilizer should be applied to increase its disease resistance.

3. Reduce fertilization

Reason: Many flower lovers believe that applying more fertilizer to peony will make it grow faster. In fact, this is not the case. If the amount of fertilizer is too large, root rot will occur.

Solution: Apply fertilizer in moderation, but not too much. Apply appropriate phosphorus and potassium fertilizers during flower bud differentiation and bud formation. No topdressing is needed at other times. If the amount of fertilizer applied is large, increase the amount of watering to allow the fertilizer to be discharged as soon as possible.
