Healthy snake plants typically have green leaves with silver or yellow streaks. If you notice yellow or brown leaves, it may be due to several conditions, such as overwatering, pests, or root rot. It's important to manage the plant's water level appropriately to address these issues. Overwatering can cause root rot and stress the plant, making it more prone to pest infestations.

Snake plants are known for their upright growth and sturdy leaves, but a number of factors can cause them to droop or flop over. These include overwatering, inadequate lighting, and poor soil quality. If the soil is not well-draining, it can become waterlogged and negatively affect the plant's foliage. To remedy this, it's important to move the plant to a brighter location, reduce watering frequency, and consider repotting it in a well-draining soil mix if necessary. By taking these steps, you can help your snake plant regain its upright posture and maintain its overall health.

Thrips can cause curled leaves in plants and are a common pest infestation. To check if thrips are the cause, inspect your plant's leaves closely using a magnifying glass. These pests are tiny and black in color. If you identify thrips, cut away severely curled leaves and spray the plant with neem oil or vegetable soap to control the infestation. This will prevent the pests from damaging new leaves that will eventually grow.
