How to deal with root rot in Christmas cactus? Teach you the correct rescue method

Root rot in Christmas cactus is caused by overwatering and too-concentrated fertilizer, so at this point you need to reduce watering and reduce the concentration of fertilizer used. The parts that have already rotted should be cut off promptly, soaked for disinfection, and repotted in loose, breathable soil. After repotting, no watering is needed for three to five days, and after ten days new roots will grow again from the base.

What to do when Christmas cactus roots rot

1. Reduce watering

The main cause of root rot in Christmas cactus is overwatering, watering before the soil in the pot has dried out completely. If the soil drains poorly, water will accumulate around the roots, causing the plant's root system to have difficulty breathing, preventing aerobic respiration and leading to root rot. At this point you need to reduce the amount of watering and replace the soil with loose, breathable soil.

2. Reduce fertilizing

Another cause of root rot in Christmas cactus is too much fertilizer, fertilizer that is too concentrated, burning the roots and causing fertilizer burn. Christmas cactus is not a fertilizer-loving plant, and its root system is not well developed either. If concentrated fertilizer is applied, the roots will find it hard to absorb, the soil concentration will be too low, and the plant will be unable to absorb water and nutrients, causing the roots to rot. You need to reduce the amount of fertilizer, apply more dilute fertilizer, and dilute the fertilizer by watering.

3. Prune the rotten roots

After root rot, take the Christmas cactus out of the pot, remove the parts of the roots that have already rotted, soak in potassium permanganate solution for disinfection, air-dry in a ventilated place for about one day, then replant it in loose, breathable, well-draining soil. You can choose yellow sand mixed with garden soil, and place it in a ventilated, breathable environment where it will not be exposed to rain.

4. Care after repotting

After repotting, no watering is needed for three to five days, and after ten days new roots will grow again from the base. If the plant is relatively large with many branches and leaves, you should also prune some of the branches and leaves to reduce water evaporation, which helps it re-root. After rooting, switch back to normal fertilizer and water management.
