What to Do About Root Rot in Snake Plants? Detailed Explanation of Causes and Treatment Methods

The snake plant (Sansevieria) is a very common houseplant grown for its foliage. Its leaves have grayish-white and dark green banded patterns, just like the stripes of a tiger, and since the whole plant stands fairly upright, it looks very resolute and imposing. As a foliage plant with strong adaptability, many people have encountered root rot while growing it. What causes this? What should you do after a snake plant develops root rot? Below, Qinnong Web explains it for everyone.

I. Causes of Root Rot in Snake Plants

Before introducing the treatment methods after a snake plant develops root rot, let us first introduce the causes of root rot in snake plants. Qinnong Web has summarized four points here for everyone's reference. If the snake plant in your home shows signs of root rot, you can first check it against these four points.

1. Overwatering

The root system of the snake plant is not well developed and consists of fleshy roots, so it is often planted shallowly. Some flower enthusiasts water too much, and the water in the potting soil cannot evaporate in time, so over time this leads to root rot in the snake plant.

2. No Soil Change

Snake plants are usually repotted with fresh soil once every two years. If the soil is not changed for a long time, the nutrients in the soil are depleted, and air is scarce, which hinders root respiration and causes root rot. In addition, long-term fertilizing means the fertilizer effects cannot fully dissipate and accumulate in the potting soil, seriously affecting root growth.

3. Poor Ventilation

Snake plants do not have high light requirements, but the environment must be well ventilated. If kept in a stuffy, hot state for a long time, the leaves cannot absorb water, which likewise affects the growth of the root system.

4. Pests and Diseases

During the growth of the snake plant, it can be harmed by root rot disease and nematodes, causing root damage and even decay.

II. Treatment Methods for Root Rot in Snake Plants

A snake plant that has already developed root rot can be repotted. First clean off the rotted part of the roots. If conditions allow, you can sterilize with carbendazim fungicide, or soak it in a 1000-fold potassium permanganate solution for about an hour, then rinse it with clean water, let it dry in a cool, shady place, and replant it.

III. Prevention Methods for Root Rot in Snake Plants

Once we know the causes of root rot in snake plants, we have also found the ways to prevent it. There are mainly the following two points:

1. Repot Regularly

Snake plants need to be repotted once every two years. When repotting, replace half with new soil, and expose the soil to the sun or water it with a sterilizing agent for disinfection. Choose fertile, loose, well-draining soil rich in humus.

2. Water Less

The growth of snake plants does not require much water; just keep the potting soil moist. If you do not know how much water to give, you can use the soaking method to reduce water accumulation in the pot. Reduce watering in winter.

The above is the related introduction Qinnong Web has prepared for everyone on what to do about root rot in snake plants. I wonder if you have noticed that, apart from the effects of pests and diseases, most of the causes of root rot in snake plants are closely related to its growth habits. If we can fully understand the growth habits of snake plants before growing them, we can greatly reduce the probability of root rot occurring.
