How to care for a snake plant
It’s the plant that forgives almost everything. To look after it well, you only need to know two things: it likes light and it hates wet feet. The rest is detail, and it’s all here.
To care for a snake plant, give it indirect light, water only when the soil is dry all the way down and use cactus soil in a pot with a drainage hole. With an east-facing window and a 16 cm plastic pot, watering comes round every 12 days in July. The mistake that kills it most is watering too much.
How much light does a snake plant need?
A snake plant (Dracaena trifasciata) copes with anything from sun to shade, even a dim corridor, but grows best in bright spots near a window. It tolerates morning sun if it gets used to it gradually; hot afternoon sun through glass can scorch it. More in can a snake plant live in low light or sun?.
How do you water it without overdoing it?
It stores water in its thick leaves and forgives a missed watering far better than an extra one. In winter growth slows and it barely wants water, unless it sits somewhere very warm. One line sums it up: water only when the soil is dry all the way down. Check with a skewer pushed into the pot, and when you do water, soak everything and empty the saucer. The rhythm follows the light:
| Where it lives | In July | In January |
|---|---|---|
| South- or west-facing window | 11 days | 21 days |
| East-facing window | 12 days | 24 days |
| North-facing window | 19 days | 38 days |
| Hallway or corner with no window | 27 days | 54 days |
The spot-by-spot detail is in how often to water a snake plant.
What soil and pot should I choose?
- Free-draining cactus soil (peat-free, if you can), lightened with coarse sand or perlite if it’s multipurpose compost.
- A drainage hole, always.
- A heavy, stable pot, terracotta ideally: it lets water evaporate and doesn’t tip over with tall leaves.
What temperature does it like?
Ordinary room temperatures, roughly 15 to 24 °C, suit it, and it should never drop below 10 °C. Keep it away from radiators, cold windows and draughts in winter.
Does it need fertiliser?
Very little: once a month from spring to late summer, with a liquid houseplant or cactus fertiliser, well diluted (half strength, for a general one). Nothing in autumn or winter.
How do you clean it?
Run a damp cloth over the leaves from time to time. They lose the dust and the plant makes better use of the light. While you’re at it, glance at the base and the undersides: mealybugs and spider mites are the pests that turn up.
When do you repot it?
Rarely: it likes tight roots, and only needs a new pot once roots and leaves fill or deform the old one. Pick one only slightly bigger, during the growing season. Read when to repot a snake plant.
What should I do when it shows a problem?
| What you see | What it usually is | Where to read |
|---|---|---|
| Yellow leaves | Too much water | Yellow leaves |
| Soft or flopping leaves | Too much water or too little light | Drooping |
| Brown tips | Uneven watering, salts, sun | Brown tips |
Which snake plant do I have?
There is the classic, with tall, upright leaves, the yellow-edged one (‘Laurentii’) and the lower rosette types such as ‘Hahnii’. The care is the same; the size changes, and the yellow edges only survive if you propagate by division.
Which room suits it best?
Almost any with a bit of light: a bedroom, an office, a hall, a bright bathroom. Better light means better growth, but it won’t sulk in a dimmer spot. In winter, avoid draughts by doors.

Quick questions
Does a snake plant purify the air? It’s often said, but at home a single plant makes no measurable difference. Enjoy it for its looks and its toughness.
Is it good for beginners? Yes, it’s one of the most forgiving plants there is. The only thing to learn is to resist watering it too often.
Is a snake plant the same as mother-in-law’s tongue? Yes, that’s a common nickname, and Sansevieria is its old botanical name. The snake plant page shows the other names and the watering for each spot.
Caring with very little
It’s the ideal plant for anyone who forgets, as long as you really forget. The Verdejar app works out the rhythm for yours, from its light and pot, and reminds you only when it’s needed.
