First step towards repotting your snake plant is to remove it from its current pot. Then, take a look at her roots – make sure to cut dead or damaged ones. Once you do, transplant your snake plant into a bigger pot filled with well-draining soil. Gently care for your sansevieria first couple of days – she will need time to recover from stress so, she’ll need light amounts of water and indirect light.

Sansevieria Masoniana can get sick and of the signs of a disease can be found on her leaves. If you notice diseased leaves, make sure to cut them to keep your plant healthy and disease-free.

Propagating snake plants is a straightforward task than can be done using leaf cuttings. Cut a leaf and let it form a callus. Once it does, plant it in well-draining soil. Roots will develop after some time, but by then make sure to water sparingly. Another way of propagation is division – if your Sansevieria Masoniana has offsets, remove her from soil. Separate the offsets and plant each of them in a separate container.
