how often should i water a snake plant?

every 3–4 weeks in summer, monthly or less in winter. when in doubt, wait another week — a snake plant stores water in its leaves and genuinely prefers being forgotten.

can a snake plant live in a dark room?

yes — it survives genuinely dark corners better than almost any houseplant. it grows slower there and drinks far less, so cut the watering in half. 'survives' is the honest word; it grows fastest in bright light.

why is my snake plant mushy at the base?

root rot from overwatering — the only common way a snake plant dies. cut away everything soft, and if healthy firm leaves remain, let them callus for a day and repot in dry cactus mix. water nothing for two weeks.

do snake plants really purify the air?

barely, at household scale — the famous NASA study used sealed chambers and you'd need a jungle per room for a measurable effect. buy it because it's sculptural and unkillable, not as an air filter.

snake plant: thrives on neglect

snake plant — Sansevieria trifasciata

the short answer

a snake plant is nearly impossible to kill except by overwatering: it tolerates everything from a dark corner to a bright window and only needs water every 3–4 weeks (monthly or less in winter). the single failure mode is root rot from soggy soil — a mushy base means you loved it too hard.

9/10

the only plant that prefers you forget it.

the experiment i didn't mean to run

mine lived in a hallway with one sad north window. i watered it when i remembered, which was roughly never. one year later: two new leaves and an attitude. this plant survived the victorian era on gas lamps — it will survive your apartment.

the only way to kill it

love. specifically: water. a snake plant in soggy soil rots from the bottom up, and by the time you notice, it's a salad. if you're an overwaterer, this is paradoxically the worst easy plant for you.
