What to Do About Root Rot in Peonies? Cause Analysis and Solutions

1. Soil that is too wet

In most cases, its root rot is caused by soil that is too wet. Because once the soil is too wet, standing water is very likely to remain in the soil, and its roots are then easily soaked in the water and rot. In addition, overly wet soil is very suitable for the reproduction and spread of certain pathogens, and root rot disease and stem base rot are very likely to develop, which can also cause its roots to rot.

Solution: First we need to find a way to drain the excess water from the soil. If it is potted, we can place it in a ventilated, shady spot and wait for the moisture to evaporate. If it is planted in the ground, we can loosen the soil to let more air into it.

However, if the situation is more serious and it has already become diseased, then besides letting the soil dry out, we also need to use thiram or other chemicals to treat it. But if it is potted, it is relatively simple. We can directly take it out, disinfect it, and replant it in new soil.

2. Pest damage

If you do not usually take care of it carefully, it is also very likely to get pests. Besides some pests on the leaves, there are also some underground pests, and these pests will bite and rot its underground roots and stems, causing its roots to rot.

Solution: If this is the case, we need to drench its roots. Although it takes more time and is quite laborious, it is also quite effective. In addition, we can also use some medications to assist in dealing with this problem, such as thiamethoxam and pyrethroid-type products, which are quite good, not only very effective but also leaving no residue.
