Sansevieria Trifasciata do well when you almost forget about them. Allow soil to dry between waterings and take extra special care not to over water in winter. Try to avoid getting leaves wet when you water. Place your snake plants in indirect light (although they are tolerant of a variety of light conditions) and fertilize during the growing season with an all-purpose plant food.
Warning: this plant is toxic to cats and dogs. Chewing or ingestion can result in vomiting and diarrhea.
