Snake plants are succulents, also known as Dracaena Trifasciata, Sansevieria, or the fun moniker ‘mother-in-law’s tongue’
Overwatering can cause all kinds of problems for Snake Plants, which is the most common cause of droopy leaves. When air spaces in the structure of the soil are filled with water for too long, the roots can’t “breathe,” and root rot will set in.
Soil structure is important for a plant’s well-being. Snake plants, being a type of succulent, need loose, very well-draining soil that affords the roots plenty of air space and drainage.
A severely rootbound plant won’t be able to get the nutrition or air it needs, so it can become stunted and droop with yellowing leaves. You can see if your plant is rootbound by turning the pot on its side and gently removing the root ball from the pot.
