What to Do When a "Ten Thousand Layers Mountain" Cactus Has Root Rot? Here's the Correct Way to Handle It

Reasons for Root Rot

Ninety percent of the time, root rot in the "Ten Thousand Layers Mountain" cactus (a Cereus cactus) comes down to watering. First, think back to whether you watered it too much before, then check whether the soil in the pot is too moist. If so, you can basically confirm that the root rot is caused by overwatering.

Light

The "Ten Thousand Layers Mountain" cactus belongs to the Cactus genus, and plenty of sunlight and good ventilation are essential for its survival. If overwatering is ruled out as the cause of root rot, consider whether the potted plant has been kept for a long time in a shaded environment where it gets no sunlight. To grow this cactus, you first need to know that it is a sun-loving, drought-tolerant plant. Once it gets no light and too much water, problems that hinder its growth will naturally appear.

How to Handle Root Rot

Cut Off and Air-Dry

Once you find that the "Ten Thousand Layers Mountain" cactus has root rot, immediately take the plant out of the soil. First cut off the rotten roots, then place it in a well-ventilated spot with indirect light to air-dry, letting the excess water in the roots evaporate naturally.

Replace the Soil

After root rot, the "Ten Thousand Layers Mountain" cactus also needs its original potting soil completely replaced. The new soil must be sandy soil with good drainage. Remember not to water it again; only when the plant grows new roots can you resume your regular watering routine.

Replant

For replanting, you can either take the plant apart for cuttings or simply plant the treated plant back into the soil. Then observe it carefully for a period of time, and once new roots grow, you can relax.
