Water your snake plant only when the soil has dried out completely, which in warm months means about every two to six weeks. The single most important rule of snake plant watering is to wait for dry soil, never to follow a fixed calendar. A bone-dry pot is what this plant wants from you. So put your watering can away and check the dirt first.
My own snake plant pushed out firm, upright leaves within a month. The change came after I stopped watering it every Sunday. Now I soak it only once every three weeks. Before that switch the leaves had gone soft and folded over at the base. A few near the soil turned mushy and yellow. The pot stayed damp for days because I kept topping it up out of habit. I backed off the water, and the new growth came in stiff and green again.
Here is why the dry-soil rule works for you. Snake plants are succulents, so they store water inside their thick, fleshy leaves and draw on that supply between your waterings. When you let the soil stay soggy, water fills the air pockets around the roots and suffocates them. The roots cannot breathe, they start to rot, and root rot is the primary cause of death for this plant according to Penn State Extension. The damage starts underground long before your leaves show it.
So how often to water snake plant pots depends on the season more than anything else. During the spring and summer growing season, every two to six weeks is the normal range that NC State Extension points to. In winter the plant slows down and drinks far less, so you may water it only every one to two months. Always confirm the soil is dry first, no matter what time of year it is for you.
Push a finger a couple of inches into the soil; only water if it feels completely dry all the way down.
Pour water through the soil until it drains from the holes in the bottom of the pot.
Empty any saucer so the pot never sits in standing water, which is what causes root rot.
Let the soil dry out fully again before the next watering, every few weeks in summer and far less in winter.
The finger test takes all the guesswork out of timing. Push a finger about two inches into the soil before you reach for the watering can. If you feel any moisture down there, wait a few more days and check again. Only water once that depth feels dry and crumbly. This one check beats any schedule because it reads the plant's real needs.
Your pot matters as much as your timing. Use a container with drainage holes in the base so extra water can escape instead of pooling around the roots. A pot with no holes traps that water and undoes everything the dry-soil rule is meant to prevent. Pair the holes with a gritty, fast-draining mix and the soil will shed water the way this plant likes.
The best part of your snake plant watering schedule is how forgiving it is. This plant can sit for a month or more with no water at all and show no harm. That cushion means erring dry is far safer than erring wet. A thirsty snake plant recovers in days, while a waterlogged one may not recover at all. When you are not sure, skip the watering and wait. Dry is the safe side for you to land on.
