This plant is perfect for those who are into neglecting plants. It is waaaay better to underwater this plant than overwatering it. Don't forget to repot this plant once the rhizome starts touching the side of the pot! People have reported hearing loud shot-gun type bangs in the middle of the night before due to their Sansevieria shattering their pot!
