How to Handle Snake Plant Root Rot in Winter

The snake plant (Sansevieria) has very high ornamental value and is also highly effective at purifying the air. However, you need to master the right techniques during care, because if you water too much or the temperature doesn't meet its requirements, the plant is quite prone to root rot.

Even in winter, many gardening friends often run into the problem of snake plant root rot. So how do you deal with snake plant root rot in winter? When you run into root rot, don't just throw the plant away. Let me teach you how to rescue it.

After a snake plant develops root rot, its leaves often show signs of yellowing, withering and wilting too. When the plant develops root rot, the first thing you need to do is take it out of its original pot. Potted snake plants are usually planted several to a pot, so after removing them from the pot, we should promptly separate the plants with root rot from those without and treat them differently.

For the intact plants, first lay them in the sun to dry for a while, about a few days, and replant them in a pot only after the excess moisture has evaporated. For snake plants whose roots are damaged or rotted, if the stems and leaves are still sturdy and have not shrivelled or died, you can cut them off for cuttings to propagate.

Snake plants root very easily from cuttings. Generally, cut a healthy 5-6 cm section from the stem and leaf as the cutting, that is, the middle part. Do not use the root end or the top end; use the middle part as the cutting to propagate new plants. Usually you just insert it into clean plain sand.

But note that before taking cuttings, the cuttings need to be laid in the sun to dry for a while. In winter, about 3 days of sunning is usually appropriate, and the wound should basically congeal and heal. If the wound has not congealed and you take the cutting directly, rot very easily occurs. Also, when taking cuttings, you must distinguish which end is the bottom and which end is the top, and insert the bottom end into the medium, without getting them the wrong way round.

If the roots have only slightly rotted, then we just need to cut off the rotted roots and replant, to prevent the rot from spreading further and infecting the other healthy roots. But before planting, you still need to lay it aside to dry for about 3 days, and likewise wait until the wound on the roots has congealed before potting, so as to avoid continued rotting.

Finally, let me say that when caring for snake plants in winter, on the one hand you should focus on temperature control, and on the other hand you should control watering sensibly, following the principle of "better dry than wet", so you can effectively prevent the plant from developing root rot. Because the snake plant itself is fairly drought-tolerant, even if you don't water it for 1 month in winter it generally won't dry out and die, while watering too much is more likely to cause root rot.
