Water your Monstera Dubia (Monstera dubia) every 1–2 weeks, letting the top 2–3 inches of soil dry out between waterings. That is the short answer: check the soil first, and water when the soil tells you to, not because a particular day of the week has arrived.
Monstera Dubia is the shingling monstera: as a juvenile its small, heart-shaped leaves press flat against a board or tree trunk, overlapping like roof tiles, and only when it climbs high does it produce large, fenestrated adult leaves. That shingling habit means it is almost always grown on a flat support, and the support and the pot dry at different rates.

How to check whether it needs water
Push your finger 2–3 inches into the potting mix: if the soil at that depth feels damp, wait; if it feels dry, water. Check in two or three spots, because soil dries unevenly — the side facing the window dries first and the centre of the root ball dries last. Never judge by the surface alone: the top can look bone dry while the roots below are still sitting in damp mix.
Check the top 2–3 inches of pot soil with your finger — the shingled leaves themselves tell you little, since they are pressed against their board. Lift the pot too: dubia is usually in a modest pot for its leaf size, and a light pot means the mix is dry even if the surface looks dark.
A moisture meter pushed halfway down the pot removes the guesswork in larger pots, and so does the weight of the pot — lift it just after watering, then again a few days later. A pot that feels surprisingly light needs water even if the surface still looks dark. Our watering calculator can give you a starting point for your pot size.
Watering through the seasons
Monstera Dubia grows in spring and summer and rests in autumn and winter, and its thirst follows that rhythm: in the growing season it uses water faster and you will water at the shorter end of the every 1–2 week range.
Dubia grows in spring and summer and needs water every 1–2 weeks then, sometimes weekly in a warm room if the pot is small. In winter it slows right down; stretch the interval, let the top dry fully, and keep it warm — cold, wet soil is the fastest route to the root rot in its problem list.
In winter, growth nearly stops and the same pot that dried in a week in July can take two weeks or more to dry in January. The danger in winter is cold, wet soil — water sitting in a cold pot is what rots roots. Keep the plant in its 65–85°F comfort range, away from cold windows and draughts.
What changes how often you water
Pot, light, humidity and temperature change the interval more than anything else. A small pot dries far faster than a large one, terracotta dries the mix faster than plastic or glazed ceramic, and a chunky, bark-heavy mix drains and dries faster than dense, peat-based soil. A plant in bright indirect light uses water steadily, while the same plant in a dim corner grows slowly and the soil stays wet far longer — and Monstera Dubia likes moderate to high humidity, which slows evaporation and stretches the interval.
The support changes everything. A board or plank does not hold water the way a moss pole does, so the plant relies entirely on the pot — but a small pot under a climbing plant dries fast in bright indirect light. A chunky aroid mix dries faster still. If your dubia is mounted high on a wall where warm air collects, check the soil twice as often as a plant at floor level.
Signs of overwatering
Overwatering is the most common way to kill a Monstera Dubia, and it is almost always a watering-too-often problem rather than a watering-too-much-at-once problem: the soil stays wet, air is pushed out of the mix, and the roots suffocate and rot. The data lists these problems for this plant: yellow leaves (overwatering or poor drainage); brown leaf edges (low humidity or salts in water); no fenestrations (not enough bright light or young plant).
Yellow leaves from overwatering or poor drainage and root rot from soggy soil are both listed problems for dubia. Because the leaves are pressed to a board, early yellowing can hide behind the foliage — check the leaves at the base of the plant and the stem where it meets the soil, where soft, dark tissue shows first.
A musty or sour smell from the soil, fungus gnats around the pot, and leaves that feel soft and limp on wet soil are further signs. If you catch it early, stop watering and let the pot dry out; if the roots are soft and dark, cut away the rotted roots and repot in fresh, dry, free-draining mix.
Signs of underwatering
Underwatering is less dangerous than overwatering, because a thirsty plant usually recovers from a good soak. The first sign is drooping: leaves go limp and lose their gloss. Next come brown, crispy leaf edges and tips, older leaves yellowing and dropping, and soil shrinking away from the sides of the pot.
An underwatered dubia's shingled leaves lift away from the board, curl at the edges and crisp. Brown leaf edges — listed as a problem, from low humidity or salts in water — appear when the plant is left dry repeatedly, and growth stalls: no new shingles appear for weeks.
To revive it, water thoroughly until water runs from the drainage holes — or stand the pot in a basin of water for twenty minutes if the mix has shrunk and water is running around the edges. Then return to checking the soil and watering deeply when the top is dry, rather than watering little and often.
How to water it properly
When the soil check says it is time, water thoroughly: pour slowly and evenly until water runs freely from the drainage holes, then empty the saucer so the plant never sits in standing water. Bottom watering works too — stand the pot in a few centimetres of water for fifteen to twenty minutes, then let it drain — and it is useful when the mix has dried out or you want to keep water off delicate leaves. Either way, the pot must have drainage holes, and use room-temperature water, since very cold water can shock tropical roots and hard tap water leaves salts that brown the leaf edges. Our humidity and temperature checker can tell you whether your room suits this plant.
Frequently asked questions
Can I water my Monstera Dubia on a fixed weekly schedule?
No — use the soil, not the calendar. Every 1–2 weeks is the average, but a warm, bright room in July and a cool, dim room in January are different worlds. Check the top soil before every watering, and water when it is dry.
How do I know if I have overwatered my Monstera Dubia?
Check the soil first: if it is wet and the leaves are yellowing, soft or dropping, overwatering is the likely cause. The plant's listed problems are yellow leaves (overwatering or poor drainage); brown leaf edges (low humidity or salts in water); no fenestrations (not enough bright light or young plant). Let the pot dry out completely and check the roots for soft, dark, rotted sections if several leaves yellow at once.
Should I mist my Monstera Dubia instead of watering it?
No. Misting wets the leaves for a few minutes and does almost nothing for the roots, which is where the plant drinks. Monstera Dubia likes moderate to high humidity — a humidifier or a pebble tray helps far more than misting, and wet leaves can invite fungal problems.
Can I bottom-water my Monstera Dubia?
Yes. Stand the pot in a few centimetres of room-temperature water for fifteen to twenty minutes, then lift it out and let it drain fully. Do not leave it standing in water for hours, and still top-water occasionally to flush salts out of the mix.
How do I water a Monstera Dubia that is shingling up a board?
Water the pot, not the board. Every 1–2 weeks, when the top 2–3 inches of soil are dry, water the pot thoroughly until it drains. The shingled leaves get their moisture from the roots in the pot, not from the board, so soaking the board does nothing useful — and a constantly wet board can rot the stem pressed against it.
