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

When it comes to why snake plants get root rot, the cause is mostly water. The reason for saying this is that many plant lovers overlook one characteristic of the snake plant: its root system is underdeveloped. Let's analyze the specific causes and rescue methods below.

Why snake plants get root rot:

Any plant lover who has dug up a snake plant will surely have noticed that its roots are especially few and shallow. This is a sign of the snake plant's underdeveloped root system. In this situation, watering too much or too often will lead to root rot. This is especially true for some plant lovers whose flower pots are very large, which makes root rot even more likely. So to avoid root rot, you must control watering. Snake plants are drought-tolerant, so plant lovers should water as little as possible.

Plant lovers who can see this article probably already have a snake plant with root rot. The cause is important, of course, but you probably want to know how to rescue it even more. The most effective way to rescue a snake plant with root rot is to re-propagate it by cuttings.

1. Original root cutting: Clean off the rotted parts thoroughly, then disinfect and sterilize, then let dry, and replant.

2. Leaf cutting: Insert a leaf that has root tissue as a cutting. This method has a drawback: growth is slow, and a snake plant that originally had golden edges will also turn into a grape snake plant without golden edges.

What to Do About Snake Plant Root Rot: Causes of Snake Plant Root Rot

The snake plant is a common indoor potted foliage plant, also known as tiger's tail orchid, thousand-year orchid, etc. It is a perennial evergreen herbaceous plant of the genus Sansevieria in the Liliaceae family. It is suitable for decorating and arranging studies, living rooms, bedrooms, and other places for long-term appreciation. Although it is easy to grow, some plant lovers still encounter root rot in snake plants. Let's take a look below at what to do about snake plant root rot!

Causes of snake plant root rot

1. Improper watering: Root rot in snake plants is mostly caused by overwatering. Because the root system is extremely underdeveloped, it is often planted shallowly, and some plant lovers water too much while the potting soil cannot evaporate it in time. Over time, this leads to root rot in the snake plant. The correct way to water a snake plant is to water as little as possible, and to judge the amount of water based on the drainage condition of the potting soil. Only this way can root rot be avoided to the greatest extent.

2. Pests and diseases: One situation that causes snake plant root rot is the appearance of disease. When newly planting a snake plant, the growing medium must be sterilized and disinfected with high temperature or chemicals. If the snake plant has root rot or stem base rot, promptly drench with 50% thiophanate-methyl, 700x sulfur suspension concentrate, or 500x 50% carbendazim wettable powder.

What to do about snake plant root rot?

1. For a snake plant that already has root rot, clean off the rotted part of the roots thoroughly. If conditions allow, sterilize with a fungicide such as carbendazim, then dry it in a cool place and replant it to grow new roots (it is recommended to root it in cutting media such as plain sand, vermiculite + peat). You can also knock the snake plant out of the pot, gently remove the soil, cut off the rotted roots with clean sharp scissors, and preferably soak the roots in a 0.02-0.05% potassium permanganate aqueous solution for about 1 minute, then take them out, dip in a little sulfur powder or plant ash, and let dry.

2. If the root rot is not severe, you can replace it with fresh growing soil and repot it, reduce the frequency of watering, and keep it in a semi-shaded place for care. Normally you can mist the leaf surface appropriately or gently wipe off dust with a damp cloth. After new roots sprout, return to normal watering, and you can apply 1-2 times of light fertilizer, waiting until new roots and new leaves grow.

3. If the snake plant's root rot is severe and the root ball has an off smell, you must wash off the old soil, cut off the rotted roots, and replant. Before planting, soak the roots in 800x potassium permanganate solution to prevent rot and promote rooting. The growing soil should be loose and well-draining. After planting, place it in a cool place for one week to recover, and frequently mist the leaf surface. During this period, do not fertilize at the roots. After new leaves extend, return to normal care.

How to grow snake plants

1. Soil: Snake plants are not strict about soil and can be managed fairly extensively. They like loose sandy soil and humus soil, and tolerate drought and poor soil. For potting, use 3 parts fertile garden soil, 1 part coal cinders, and add a small amount of soybean cake scraps or poultry manure as base fertilizer. They grow very robustly, and even when the pot is full, their growth is not suppressed. Generally repot once every two years, in spring.

2. Light: Snake plants grow well under conditions of ample light. Apart from avoiding direct blazing sun in midsummer, they should receive plenty of sunlight in the other seasons. If placed in a too-dark indoor spot for too long, the leaves will darken and lack vitality. However, indoor potted plants must not be suddenly moved into sunlight; they should first acclimatize in a dark spot to avoid scorching the leaves. If indoor conditions do not allow it, they can also be placed in a spot relatively close to sunlight.

3. Temperature: Snake plants are native to western Africa and southern Asia, and are distributed in tropical Africa and India. The suitable growing temperature is 20-30°C, and the overwintering temperature is 10°C. In winter, the temperature must not stay below 10°C for long, otherwise the base of the plant will rot and the whole plant will die.

4. Water: Snake plants should be watered in moderation, following the principle of preferring dry over wet. Normally wipe dust off the leaf surface with clean water to keep the leaves clean and glossy. In spring, when new plants sprout at the root crown, water appropriately more to keep the potting soil moist. In the high-temperature summer season, also keep the potting soil moist regularly. After late autumn, control the amount of watering and keep the potting soil relatively dry to enhance cold resistance. During the winter dormant period, control watering and keep the soil dry. When watering, avoid pouring water into the leaf clusters.

5. Fertilizing: Snake plants do not have high fertilizer requirements. If only nitrogen fertilizer is applied for a long time, the markings on the leaves will become dull, so compound fertilizer is generally used. Fertilizing should not be excessive. During the peak growing season, apply fertilizer 1-2 times per month, in small amounts. You can use standard compost when repotting, and apply 1-2 times of dilute liquid fertilizer per month during the growing season to ensure the leaves are verdant and thick. You can also evenly bury 3 holes of cooked soybeans in the soil at the edge of the pot, 7-10 beans per hole, taking care not to let them touch the roots. Stop fertilizing from November to March of the following year.

What to do about snake plant root rot in summer

Pull the snake plant out and let it dry in the shade for half a month to completely kill the rot bacteria. Water less, and place it in a spot with strong light, but do not expose it to the sun. If you do not replant it, the rot bacteria will still be in the flower pot. Also sterilize the potting soil by exposing it to the sun. After planting, place it in a spot with strong light, and water again after another half month. Snake plants are very drought-tolerant, similar to cacti. They will not die even without water for several months; adding water once a month is enough.
