Sansevierias, apart from being a great air purifier, thrive with minimal care and live for many years, making it the perfect houseplant!
Place sansevierias in moderately bright or filtered light. Good location would be a north-facing window or in front of a bright and sunny window. Although the plant is known to tolerate very low light levels, bright light brings out the colours in the leaves while also keeping it healthy. Keep them away from direct sun.
Allow the soil to go completely dry before watering. When you do water it, make sure to. Water it deeply enough for the water to come out of the drainage hole. Never allow water to stagnate on top of the soil or do not make the soil soggy as that will lead to root rot. You can water it once a week in summers and once in 2 weeks in winters if kept in bright filtered light. After watering the plant, make sure to keep it in a bright area.
Use a fast and well draining soil to keep your Sansevieria as root rot is one of the main reason that kills the plant. You can fertilise it once a month.
