Overview

If you've ever let a plant go thirsty, the snake plant might just forgive you. Its firm, sword-like leaves shoot up straight out of the pot in bold bands of green, and it laughs off the sort of neglect that would do in a pickier plant. A while back, botanists shifted it out of Sansevieria and into the genus Dracaena, yet most folks happily go on calling it by the old name.

So why is it this easygoing? It comes down to the way the plant deals with water and light. Like a succulent, those chunky leaves bank moisture, which lets it coast through long stretches with nothing to drink, and it's just as content beside a sunny window as it is in a shadowy nook. Since it grows slowly, one plant holds its look for years and asks for hardly any attention.

There are a couple of things to sort out before one moves in, though. The leaves contain saponins that don't sit well with cats and dogs, which makes it a tricky pick if curious pets share your space. And even though it behaves itself in a pot inside, set it loose outdoors somewhere warm and it can run wild through underground rhizomes.

Care

The short version: give it bright indirect light, a gritty mix that drains fast, and a drink only once the soil's bone dry. Keep things above 55°F (13°C), and a light feed during the growing months is plenty.

Light

Bright indirect light keeps a snake plant happiest, but honestly, few houseplants put up with low light, partial shade, and partial sun as gracefully as this one does. The catch is pace: a darker corner means slower growth. Steer it clear of harsh, direct afternoon rays, which leave scorch marks on the leaves.

Water

More snake plants meet their end right here, so lean toward keeping things dry. Let the soil go completely dry before the next drink, which tends to mean a watering every 2 to 4 weeks while it's growing and just every 4 to 6 weeks once winter rolls in. Not sure? Hold off.

Soil

Pot it up in a well-drained sandy or cactus mix that sends water straight through instead of holding onto it. pH isn't a big deal to this plant, and it's happy anywhere from 6.0 to 8.0. Honestly, a pot with a drainage hole counts for more than nailing the exact recipe.

Temperature

Regular room temperature does the job nicely, somewhere between 55°F to 84°F (13°C to 29°C). At heart it's a tropical plant, so hold it above 55°F and tuck it away from chilly drafts and freezing windowpanes through winter.

Humidity

Everyday household air suits it just fine, and a dry room won't trouble it one bit. Skip the misting and forget the humidifier. Because the leaves keep their own moisture on hand, parched winter air rolls right off them.

Feeding

Feeding a snake plant is barely on the to-do list. Offer a balanced all-purpose feed at half strength, once a month through spring and summer, then put the bottle away the moment growth tapers off for winter. Overdoing the fertilizer hurts it more than skipping it altogether.

Pruning

Pruning? There's next to none. Simply trim off any damaged or dead leaves right at the soil line with a clean blade, and the plant smartens itself up. A leaf cut this way won't sprout again from the cut, so pull whole leaves rather than snipping their tips.

Repotting

A snug pot actually suits a snake plant, so only repot it every 3 to 5 years or whenever it's clearly outgrown its home. Watch for the tells: roots poking through the drainage holes, a pot that's cracked or bulging, or rhizomes and pups jostling at the top. Bump it up a single pot size in fresh gritty mix.

Size & spacing

Kept indoors, it climbs to 2 to 4 feet (60 to 120 cm) with a spread of roughly 12 to 24 inches (30 to 60 cm). Let a clump have a bit of elbow room to widen, since it gradually fills the pot with fresh upright leaves.

Troubleshooting

Here's the thing about snake plant troubles: nearly all of them come down to overwatering. Once you can read what the leaves and the base are telling you, you'll spot problems early. Find the match below, then sort out the root cause before it works its way down to the roots.

Severe

Squishy leaf bottoms that sat too long in wet dirt

Squishy bases like this mean root rot, and the cause is nearly always a heavy hand with the watering can. Sit a snake plant in damp mix and the roots can't breathe, so they go black, slimy, and smelly. Slide it out of the pot, snip off anything soft, settle it into a dry gritty blend, and go much easier on the water afterward.

Fix:

  • Unpot and inspect roots
  • Cut away rotted tissue
  • Repot in dry, gritty mix
  • Reduce watering
Setback

Leaves that flop sideways rather than standing tall

When the blades fan out flat, it's usually because the base has turned soft from too much water, or the plant has spent too long somewhere shadowy. Poke the soil and squeeze the base to tell which one you're dealing with. A firm base just wants more light, but a mushy one means you tackle the rot down at the roots first.

Fix:

  • Correct watering and check roots
  • Move to brighter indirect light
Setback

Little white fuzzballs tucked down in the crevices

See fuzzy white blobs wedged where the leaves meet the dirt? Those are mealybugs, little sap-drinkers that love a sheltered crevice. Touch each one with a swab dipped in alcohol, give the plant a round of insecticidal soap, and park it apart from your other greenery until you're sure it's spotless.

Fix:

  • Wipe with alcohol-dipped swab
  • Treat with insecticidal soap
  • Isolate plant
Setback

Dull, spotty leaves covered in wispy little webs

A dusty, speckled surface threaded with thin webs is the calling card of spider mites, and they tend to arrive when the air gets too dry. Hose down the foliage to knock the bulk of them loose, then go in with insecticidal soap or horticultural oil. Give the leaves a regular wipe and they'll be far less likely to come back.

Fix:

  • Rinse foliage
  • Apply insecticidal soap or horticultural oil
Setback

Soft, see-through spots after it catches a chill

This plant comes from the tropics and really hates the cold, so soft, glassy scarring tends to crop up after a dip below 55°F (13°C) or a night spent leaning on an icy pane. Carry it somewhere cozy, cut off the leaves that got hit, and through the winter keep it well away from any chilly draft.

Fix:

  • Move to warm spot above 13°C / 55°F
  • Remove damaged leaves
Cosmetic

Pale, faded blotches on whatever side faces the sun

Washed-out, dry blotches on the side that catches the window are sun scorch, plain and simple, from sitting in too much fierce light. Bright indirect light is a treat for this plant, but blazing afternoon sun is another story and it'll burn. Pull it back from the glass into gentler light, and the fresh leaves come up unmarked.

Fix:

  • Move out of hot direct sun to bright indirect light
Cosmetic

Almost no fresh leaves and a kind of stretched look

When nothing new shows up for ages, the plant is almost certainly short on light, though it also takes a winter breather. Shift it to a brighter indirect spot and you'll see it kick back into gear as the days get longer. Tucked in a gloomy nook it'll hang on just fine, but don't expect it to actually grow.

Fix:

  • Move to bright indirect light
Cosmetic

Flat leaves looking drab under a dusty coating

Those wide, flat blades are great at catching dust, and a coating of it mutes the color while shading the leaf a touch. No need to worry, since it's totally harmless. Run a damp cloth over each leaf now and then, and that rich green shine returns straight away.

Fix:

  • Wipe leaves with a damp cloth

Toxicity

Pets and snake plants aren't a great mix, plain and simple. The leaves hold natural compounds called saponins that leave cats and dogs drooling, throwing up, and dealing with diarrhea. People mostly shake them off, but since the leaves are bitter and were never meant as food, keep the pot somewhere animals and little kids can't get at it.

Toxic to

Cats · Dogs · Horses · Rabbits · Livestock · Birds

Safe for

People

Cats Moderate

Chew on a leaf and a cat tends to drool first, then bring it back up, with diarrhea not far behind. Saponins taste pretty awful though, so most cats quit after one bite.

Dogs Moderate

It plays out about the same for a dog: drooling, throwing up, and runny stools once they've had a mouthful. Things rarely get scary, but if yours really went to town on it, ring the vet.

Horses Caution

Those saponins will turn a horse's stomach too, but let's be honest, a pot on the windowsill is nowhere near a horse anyway.

Rabbits Caution

Between the bitterness and the saponins, these leaves are a bad idea for a rabbit to nibble, so keep the plant somewhere those teeth can't reach.

Livestock Caution

If goats, sheep, or cattle grazed on the foliage they'd likely end up with a sore belly from the saponins, though a houseplant hardly ever lands in their path.

Birds Caution

A nosy pet bird might take a peck and wind up with the same queasy gut, so put the pot somewhere it can't land.

People Caution

Saponins don't really faze people, but the leaves taste bitter, aren't food, and the sap can leave touchy skin a bit itchy. Just don't let little kids gnaw on them.

Sap/saponins may irritate skin; keep leaves out of reach

Varieties

There's a wider mix of snake plant shapes and colors out there than you might guess, from tall striped swords to squat little rosettes. Here are the ones you're most likely to come across.

'Moonshine'

Known for wide, silvery pale-green blades that show next to no banding or markings.

'Laurentii'

The well-loved classic with bright yellow edges, though those gold margins drop away and turn back to plain green if you raise it from leaf cuttings.

'Hahnii' (Bird's Nest)

A compact type that bundles 6 to 12 leaves into a short, funnel-shaped rosette rather than sending up tall blades.

'Black Gold'

Sets very dark, almost-black green leaves against a sharp golden-yellow rim.

'Bantel's Sensation'

Has slim, very erect leaves marked with vertical streaks of white.

How to propagate

Making more snake plants is a breeze, and you've basically got two ways to go: pull a grown plant apart at the roots, or root pieces of a single leaf. One holds the leaf color steady, while the other lets it slip.

DivisionEasy

Anytime; best at spring repotting · A few weeks

Want more snake plants? The easiest path is to take one you've got and divide it. Any time of year works, though it lines up nicely with a spring repot. Tease the clump apart so every chunk of rhizome and pup hangs onto some roots, pot each one up, and they'll find their feet within a few weeks. Since you're splitting rather than rooting a leaf, the variegated ones stay true to their parent.

Leaf cuttingsModerate

Spring to summer · Roots in about 2-3 months

Another option is starting a fresh plant from just one leaf. Slice a healthy leaf into pieces, set them upright in damp mix over spring or summer, and they'll put down roots at a leisurely pace across about 2 to 3 months. Just know there's a trade-off with color: variegated picks like 'Laurentii' shed their stripes and return to plain green, so go the division route if the pattern matters to you.

Myths

Myth

A snake plant tidies up the air in your home.

Reality

The idea traces to an old NASA test done in a sealed box, which is nothing like the room you live in. Studies done properly since then find that a handful of pots barely touch the pollutants in your air. Cracking a window cleans things up way more than any plant ever could.

Myth

Snake plants are basically unkillable.

Reality

Sure, they're tough as nails, yet there's one chink in the armor. Soggy roots from overwatering will finish one off quicker than anything, and a sharp cold snap can wreck the leaves too. Keep the water sparse and they'll stick around for ages.

Myth

Snake plants can just coast for months with nothing to drink.

Reality

Few houseplants ride out a dry spell as well as this one, but it's no cactus, right? A month or so is fine, forever isn't, and sooner or later it really does want a proper soak to stay in good shape.

Myth

They thrive in a pitch-dark room.

Reality

Dim and dark aren't the same thing at all. Stick one in a shadowy corner and it'll cope, but light is still what fuels its growth, and parked in real darkness it just stalls out and slowly declines.

Myth

Take a cutting off a striped one and it stays striped.

Reality

In cultivars such as 'Laurentii', the coloring is down to a chimera that one leaf simply can't hand down. Root a cutting and what grows back is plain green. Want to keep those stripes? Split the plant at the roots instead.

Myth

They breathe out oxygen at night, so they'll freshen the bedroom and help you nod off.

Reality

That oxygen talk rests on the plant's CAM photosynthesis, except the quantities are next to nothing. One or two pots won't shift the air in your bedroom, and nothing shows it helps you sleep either.
