The snake plant is the gold standard of low-maintenance houseplants. With architectural sword-shaped leaves and a near-supernatural ability to survive neglect, it thrives in conditions that would kill most plants — low light, dry air, infrequent watering. It is also one of NASA's best-rated air-purifying plants.

Snake Plant care guide
Light
Tolerates everything from low light to bright, indirect sun. Grows fastest in bright, indirect light. Direct sun is fine for a few hours but prolonged direct sun can bleach the leaves.
Water
Allow the soil to dry completely between waterings. In low light this can mean watering only every 3–4 weeks. Overwatering is the only reliable way to kill a snake plant — when in doubt, wait another week.
Humidity
Indifferent to humidity. Thrives in dry indoor air that would stress more tropical plants.
Temperature
Comfortable from 15–29 °C (60–85 °F). Avoid temperatures below 10 °C (50 °F) and never let it freeze.
Soil
A fast-draining cactus or succulent mix is ideal. If using standard potting soil, add 30–40% perlite or coarse sand to improve drainage.
Fertilizer
Feed sparingly — once or twice during spring and summer with a balanced fertilizer at half strength. Snake plants grow slowly and do not need much.
Pruning
Cut damaged or mushy leaves at the soil line using clean scissors. Snake plants rarely need cosmetic pruning.
Repotting
Repot every 2–3 years or when roots emerge from drainage holes. Snake plants like to be root-bound — choose a pot only one size larger.
Propagation
The easiest indoor plant to propagate. Cut a healthy leaf into 5–8 cm sections, let cut ends callus for 1–2 days, then push into moist sand or cactus mix. Roots form in 4–6 weeks.
Common Snake Plant problems
Mushy, yellow base
Cause: Root rot from overwatering.
Fix: Unpot immediately, trim all soft roots and leaves, let dry for 24 hours, and replant in dry cactus mix. Do not water for two weeks.
Brown leaf tips
Cause: Dry tap water salts or under-watering.
Fix: Use filtered water and water thoroughly when you do water — give the soil a real soak, then let it dry completely.
Drooping or splaying leaves
Cause: Insufficient light or being severely root-bound.
Fix: Move to brighter indirect light. If the pot is bulging, repot one size up.

Snake Plant FAQ
How often should I water a snake plant?
Roughly every 2–4 weeks in bright light, every 4–6 weeks in low light. Always check that the soil is completely dry to the bottom of the pot before watering. In winter, water even less often.
Do snake plants really purify air?
NASA's Clean Air Study identified snake plants as effective at removing formaldehyde, benzene and trichloroethylene from indoor air. The effect in a real home is modest compared to ventilation, but they are among the best-performing common houseplants.
Why is my snake plant falling over?
Almost always overwatering — the base rots and can no longer support the leaves. Check the lower stems for mushiness, cut away any rotten tissue, repot in dry cactus mix, and water far less frequently.
Can snake plants survive in a dark bathroom?
Snake plants tolerate low light better than almost any houseplant, but a windowless bathroom is still a stretch. They will survive a few months but slowly decline. Even an artificial daylight bulb on a timer makes a big difference.
