Snake Plant Care: Light, Water, Pets and Yellow Leaves
Dracaena trifasciata, formerly Sansevieria
Snake plants forgive dim rooms and missed waterings. What they do not forgive is wet soil, and that is the one mistake behind most of the trouble.
How to care for a snake plant
Snake plants grow in almost any light a person can comfortably work in, from a dim hallway to a bright window. Growth is slow in low light and faster in bright, indirect light. Direct afternoon sun through glass can scorch the leaves, so pull the plant back from a hot west window.
Use a gritty, fast-draining mix and a pot with a drainage hole. A heavy potting soil that stays damp is harder on a snake plant than any light level. They also like to be snug in the pot, so repot only when roots are pushing the container apart.
Where a snake plant works
Dim corner
Grows slowly, stays healthy. Fine for hallways and rooms with little daylight.
Bright, indirect light
Faster growth. A few feet from a bright window works well.
Hot west glass
Direct afternoon sun can scorch the leaves. Pull the plant back.
How often to water a snake plant
Water when the soil is dry all the way down, then soak it and let the excess drain. Indoors that usually works out to every 2 to 3 weeks, and less in winter. Treat the schedule as a starting point and check the soil first.
If you are unsure, wait. A snake plant stores water in its leaves and rhizomes and handles a dry spell far better than a soggy one.
Why snake plant leaves turn yellow
Yellow, soft or collapsing leaves almost always mean too much water. Press the base of a leaf: if it is mushy or smells sour, the roots are rotting. Pull the plant out, cut away black or soft roots, and repot in dry, gritty mix.
Yellowing with dry, crispy leaves points the other way: a long stretch without water or a spot too close to a heater or vent. Wrinkled, curling leaves usually mean thirst.
Pots, drainage and water
Most trouble with snake plants starts below the soil line. This is the set-up that keeps the roots from sitting in water, and the questions that come up most often about it.
- Rocks on a pot collar hide the rim of the liner and the soil line.
- The plant stays in its liner, a nursery pot with drainage holes, so water can leave the soil.
- A filler under the liner sets the height so the rim sits just below the top of the decorative pot.
- The decorative pot has no hole. Water that drains from the liner collects here, and has to be emptied.
My pot has no drainage hole. How do I water?
Keep the plant in a plastic liner with holes and set it inside the decorative pot. Water it in a sink, let it drain fully, then put it back.
There is water in the tray or at the bottom of the pot.
Empty it after watering. A snake plant standing in water keeps its roots wet, and that is what leads to the soft, yellow leaves described above.
How big should the pot be?
Snake plants like a snug fit. Go up one size, an inch or two wider, only when roots are pushing the container apart.
Will a tall plant tip over?
Snake plant leaves are tall and top-heavy. Choose a heavy base, keep the liner snug in the decorative pot, and use a filler so it cannot rock.
Is a snake plant toxic to cats and dogs?
Snake plants are listed as toxic to both cats and dogs. Chewing can cause drooling, nausea and vomiting, usually mild. If a pet has eaten leaf, call your vet or an animal poison hotline. Pet-safety information here follows the ASPCA toxic and non-toxic plant list.
Snake plant in offices
Snake plants suit offices because they put up with low light, irregular watering and air-conditioned dryness. The common mistake is the opposite of neglect: someone waters on a fixed schedule and the pot never dries out.
In the plant list for a recent office install of about 120 planters, snake plants were the largest line item: about 80 of roughly 240 plants, mostly the pale silver-green 'Moonshine' type in 8 inch pots, with a few taller 10 inch ones.
