Water your monstera when the top one to two inches of soil are dry. In summer that usually lands somewhere around every seven to ten days. In winter it can stretch to two or three weeks. Those numbers are a description of what tends to happen, not an instruction — the instruction is the check. Put a finger in the soil. If it is dry down to the second knuckle, water. If it is not, wait.
The reason to write this down is that most monstera deaths are not neglect. They are diligence applied on the wrong day.
Why not just water on a schedule?
Because the plant is not on a schedule. It is on a rate of water loss, and that rate is set by things that move around: how much light the room gets, how warm it is, whether the heating is running, how big the pot is relative to the roots, and what the soil is made of.
A monstera in a bright west window in July and the same monstera in the same pot in a cool January room are two different plants as far as water is concerned. A weekly routine that suits one will drown the other. Not immediately, which is the trap — the plant looks fine for a month, then several lower leaves yellow at once and the damage is already several weeks old.
What a routine can usefully set is when you check. Checking costs nothing and cannot hurt the plant. So keep your Sunday, if Sunday is when you remember. Just make Sunday the day you put a finger in the pot, not the day you automatically pour.
How do I actually check?
Push a finger straight into the soil to the second knuckle, an inch or two down, somewhere between the stem and the rim.
Dry all the way down: water it.
Cool and faintly damp: leave it, check again in two or three days.
Wet: leave it, and if it is still wet at the next check, look at your drainage before you look at anything else.
Surface appearance lies. Potting mix goes pale and crumbly on top while still holding water two inches down, which is exactly where the roots are. The finger is more reliable than your eyes and more reliable than most moisture meters, which drift badly in chunky aroid mixes.
Two other signals worth knowing. A thirsty monstera droops from the petiole — the whole leaf stalk loses tension and the leaf sags, then recovers within a few hours of watering. Lifting the pot works too: dry soil is dramatically lighter, and once you have felt both you can often skip the finger entirely.
When you do water, water thoroughly. Run it through until it comes out the drainage hole, then empty the saucer. Small frequent splashes wet the top inch and leave the root ball dry, which produces a plant that is simultaneously overwatered at the surface and thirsty underneath.
If you want a starting interval for your particular pot size, light, and season, our houseplant watering calculator will give you one. Treat it as the day to check, not the day to pour.
How does summer change it?
Longer days, stronger light, warmer air. The plant is actively growing, moving more water through itself, and losing more from the soil surface. Intervals shorten.
For most indoor monsteras in a bright spot, summer tends to land around every seven to ten days. A large plant that has filled its pot with roots may want water more often than that; a young plant in a pot it has not grown into yet, less. Both are normal.
Three summer-specific things worth watching:
- Air conditioning cuts humidity sharply. A room that feels cooler can still be drying the plant faster than the same room in June with the windows open.
- A plant moved outdoors changes category entirely. Wind and open air can take a potted monstera from a ten-day interval to a two-day one. Check daily for the first week after any move outside.
- Growth season is feeding season. A balanced houseplant fertilizer at half the labeled strength, roughly monthly, is enough. Flush the pot with plain water every few months to clear accumulated salts.
How does winter change it?
Less light, shorter days, slower growth, and a plant using noticeably less water. Intervals stretch — two to three weeks is common, and a monstera in a dim room can go longer still.
The complication is that indoor heating dries the air while the soil stays wet longer. So the leaves look thirsty — crisping edges, a papery feel — at the same moment the roots are sitting in more moisture than they want. The instinct is to water. Usually that instinct is wrong, and the finger check is what saves you.
If the air genuinely is the problem, deal with the air. Move the plant away from a radiator or a heating vent, group it with other plants, or run a humidifier. Misting looks like a solution and is not one — the effect on ambient humidity lasts minutes, and water sitting on leaves overnight in a cold room invites fungal spotting.
Also worth knowing: cold water straight from the tap in winter can shock roots. Room temperature is fine. And a monstera against a single-glazed window in January is getting a cold draft you cannot feel from across the room.
Does pot and soil change the interval?
More than season does, in most homes.
Terracotta breathes and dries faster than glazed ceramic or plastic. A pot that is much too large holds a volume of wet soil the roots cannot reach, which is one of the more common routes to root rot. Go up roughly two inches in diameter when you repot, not six.
Soil matters just as much. Monstera is a climbing aroid with thick roots that want air as well as water. Straight bagged potting soil compacts and holds moisture too long. A chunkier mix — potting mix with perlite or pumice and orchid bark worked through it — drains faster, which means you water more often and the plant is far happier for it. Frequent watering is not the enemy. Soil that stays wet is.
Drainage hole, always. If the decorative pot has none, keep the plant in a nursery pot and set it inside.
Do deliciosa and adansonii want different watering?
The method is identical. The tendency differs a little.
Monstera deliciosa is the larger plant with thicker stems and a heavier root system, and in a mature pot it tends to drink accordingly. Monstera adansonii has thinner leaves and is generally grown in smaller pots, which dry out faster — so it often wants checking more frequently even though it uses less water overall. Mini monstera is not a monstera at all, botanically — it is Rhaphidophora tetrasperma — but it takes the same treatment. It is sold out at the moment.
In every case: same finger, same threshold, same thorough soak.
Am I overwatering or underwatering?
The symptoms overlap enough to be genuinely confusing, so use the soil as the tiebreaker rather than the leaf.
Likely overwatering: yellowing that starts on the oldest lower leaves, several at once, often with soft brown patches; soil damp for more than a few days after watering; a stem that gives when pinched; sometimes a sour smell from the pot.
Likely underwatering: drooping that recovers within hours of a drink; crisp brown edges and tips; soil pulling away from the sides of the pot; the pot feeling conspicuously light.
One old leaf yellowing slowly on a plant that is otherwise fine is age, not a problem. If you want to work through it properly, our yellow leaves diagnoser asks the same questions in order.
