Water Monstera deliciosa when the upper potting mix has dried and the container feels noticeably lighter than it did after a thorough watering. A fixed interval can tell you when to check, but the soil and root zone decide whether to water.
The useful question is not whether it has been a week since the last drink. It is whether the pot has released enough of its previous water for fresh water to move through an airy mix. This guide shows how to make that call, what changes when growth slows, and what to do when leaves droop or yellow.
The quick watering rule
For a medium indoor pot, start by feeling roughly 2–3 inches (5–7.5 cm) below the surface. If the upper mix is dry and the pot is much lighter than its freshly watered weight, water thoroughly and allow the excess to drain. In a small or shallow pot, check a smaller depth; in a large deep pot, also test lower down with a wooden stick, because dry topsoil can hide a wet root zone.
If the soil is still cool and damp, wait and check again. If it is bone dry all the way down and the leaves are losing firmness, water promptly rather than waiting for an arbitrary date. The Royal Horticultural Society advises letting Monstera compost become almost dry, then watering thoroughly and keeping the pot out of standing water.
“Almost dry” describes a drying cycle, not a demand to turn every particle of mix to dust. A root-filled pot can feel light while retaining slight moisture at the very bottom, and that is different from a heavy, soggy pot. If you have just brought home a plant or changed its container, spend a few cycles learning its new wet and dry weights before assuming the old routine still fits.
A seasonal Monstera watering schedule to check, not obey
Season names are imperfect shorthand for light and growth. A Monstera in a bright room may keep growing during a mild winter, while one moved farther from a window may use less water even in summer. Use the following reminders to inspect the plant; none is a guaranteed watering interval.
| Condition | When to start checking | Water when | If still damp |
|---|---|---|---|
| Active growth and brighter light | A few days after the last watering; check more often if the pot dries fast. | The upper mix is dry and the pot feels lighter; confirm the deeper zone is not soggy. | Wait and check again in a day or two. |
| Growth slowing or reduced light | Check less often than during active growth. | The same soil and weight clues agree. | Allow more time; look for a persistently wet lower pot. |
| Cooler, dimmer winter conditions | Inspect periodically rather than watering on a set day. | The mix is approaching dry through much of the root zone and the pot is lighter. | Hold water; check again after several days. |
Intervals such as seven days or three weeks are examples of what some rooms produce, not targets for your plant. Light, room temperature, pot size, root mass, ventilation, humidity and mix all change how quickly water disappears. In consistently warm, bright indoor climates, the plant may have no pronounced winter slowdown at all.
A practical diary can record the last watering date, the room’s light, how far down the soil felt dry and whether the pot was heavy or light. After several cycles, you may notice a useful checking rhythm. Keep it flexible: moving the pot, closing blinds, switching on heating or repotting can change the pattern immediately. If the plant has not used much water since the last check, the appropriate next action is simply to wait.
Use the finger test and pot weight together
Press a finger into the mix away from the thickest roots. Dry mix feels loose and does not leave cool, wet particles on your finger; damp mix feels cooler and clings. If roots or a deep pot make this difficult, insert a plain wooden stick toward the lower half, leave it briefly, then check whether it comes back moist. Avoid repeatedly stabbing the same root area.
Next, lift the nursery pot or carefully tilt a large planted container. Memorize its weight immediately after full drainage and compare it a few days later. This is a relative cue for that pot, not a weight in grams or a universal rule. If you cannot lift it safely, rely on a deeper stick check and drainage observations instead.
The top centimetre can dry while the root zone remains wet, especially under moving air or in a deep decorative planter. Our guide to why soil looks dry on top but wet underneath explains that mismatch. A moisture meter can add a clue, but readings vary by mix, probe position and contact; use it alongside touch and pot weight.
Conversely, water can run straight through a very dry, shrunken mix without soaking its centre. If the pot is still unusually light after runoff, check the middle rather than assuming that drainage alone proves it was watered well. Pour slowly in two passes or use brief bottom watering, then let it drain again. When repeated wetting leaves the centre dry, inspect whether the potting mix has become compacted or water-repellent and consider refreshing it at an appropriate repotting time.
How to water Monstera deliciosa properly
When the checks say the plant is ready, move a draining inner pot out of its decorative cover if practical. Pour room-temperature water slowly over the mix in several passes, aiming around the root area rather than one narrow channel. Stop once the mix is evenly wetted and excess begins to drain; if water immediately races down the sides of a very dry root ball, pause and repeat slowly so the middle can rewet.
- Check deeper soil and compare the pot with its known wet weight.
- Water the mix thoroughly in a sink or over a tray, allowing runoff.
- Let it finish draining and empty the saucer or decorative outer pot. Do not leave the nursery pot standing in water.
- Note the date and conditions so you learn how this pot dries; never turn the date into an automatic watering alarm.
Bottom watering can help rewet a mix that initially repels water. Stand a pot with drainage holes in shallow water until the upper mix begins to feel moist, then lift it out and drain completely. This is an occasional method, not a reason to leave the roots submerged; top watering also helps flush accumulated soluble salts. Neither method fixes a pot that has no drainage route.
There is no daily quota of water in millilitres that works for every Monstera. The volume required to wet a small root ball is different from that for a mature climbing plant; what matters is that the mix receives an even drink and the excess can escape. A small splash confined to one side may leave much of the root zone dry, while continuing to pour after the container is already saturated merely fills the saucer. Empty it after runoff has stopped, especially when a heavy outer pot makes trapped water easy to overlook.
Why the same Monstera suddenly dries faster or slower
Brighter indirect light and active new leaves often raise water use. Warm, dry air, a porous terracotta pot and an open bark-based mix can also shorten the interval. A large pot of dense mix, little light, cooler conditions, or damaged roots may keep the lower root zone damp for much longer. Humidity affects leaf water loss, but it does not tell you by itself whether roots need water.
Pot size matters especially after repotting. The RHS advises moving to a pot only a few centimetres larger than the root ball, because excess compost can stay wet too long. Choose an open, well-drained mix and a container that can release runoff. If a nursery pot sits in a cachepot, remove standing water from the outer vessel; see why some pots never drain even with holes when the bottom stays wet despite an apparent drainage hole.
The pot and mix must be assessed together. A drainage hole lets free water leave, but fine particles packed tightly can still hold more moisture than the roots can use quickly. Bark and other coarse components can create more open spaces, while a pot many sizes larger than the root mass adds a reservoir of slow-drying mix. Do not repot a stable plant merely because a watering app says the container is the wrong size; change the setup when the actual drying pattern, root condition or growth shows a problem.
Yellow leaves or drooping: check the pot before choosing a fix
Leaves report stress but do not identify its cause alone. A drooping Monstera can be thirsty, yet roots damaged by persistent wetness may also fail to supply water to the leaves. The soil and recent history are more useful than the appearance of one leaf.
| What you see | What to verify | Next step |
|---|---|---|
| Droop; pot light; deeper mix dry | Stick check confirms the root zone has dried. | Water thoroughly, drain, and reassess after the plant has time to respond. |
| Droop or several yellow leaves; pot heavy | Mix is still damp deep down; check for a soft stem base, persistent odor or dark mushy roots if decline continues. | Do not add water. Empty standing water; investigate drainage and roots if decline persists. |
| One older lower leaf turns yellow | New growth, other leaves and moisture pattern remain normal. | Monitor; a single aging leaf does not establish overwatering. |
| Brown edges; soil neither very wet nor very dry | Check dry air, direct sun, salts, pests and recent changes. | Address the confirmed cause rather than adding water automatically. |
Wet soil plus worsening droop deserves attention, particularly if the base softens or the mix smells unpleasant. Gently inspect roots if the problem continues: healthy roots tend to be firm; decayed roots are often dark and mushy. Our early root-rot signs guide covers the inspection and recovery decisions. Do not soak a plant because its wet roots are already failing.
Suppose two plants droop on the same afternoon. The first has a light pot and dry mix well below the surface, so a thorough drink is a reasonable test. The second has a heavy pot, wet lower mix and several newly yellowing leaves, so more water is the wrong first move. Empty its cover pot, verify drainage, and watch whether the wetness persists. That comparison is why diagnosing by leaf shape alone so often leads owners in opposite directions.
Water quality, misting and common mistakes
Room-temperature water is a comfortable default. In hard-water areas, rainwater or suitable filtered water can reduce alkaline mineral buildup; the RHS especially recommends these for its slightly acidic Monstera compost. If salts visibly collect on the soil or rim, review fertilizer and water source, and occasionally water from above so runoff can carry soluble residues away.
Misting is not a substitute for watering the roots. It may briefly wet leaves without making the room consistently humid, so judge root moisture separately. Wiping dusty leaves and keeping the plant away from harsh direct sun, cold drafts and heat sources are often more helpful than repeatedly spraying foliage.
The recurring mistakes are watering because the surface looks dry, keeping runoff in a decorative pot, using a large dense container for a small root ball, giving frequent tiny sips, and treating every yellow leaf as proof of overwatering. Each has a different fix. The common first step is to inspect the whole pot before adding water.

Frequently asked questions
How often should I water Monstera deliciosa in winter?
Check it periodically, then water when the mix is approaching dry and the pot feels lighter. Dimmer, cooler conditions usually slow water use, so the interval may lengthen. A warm, bright room can behave differently; let the pot determine the timing.
Can I bottom water a Monstera?
Yes, if the pot has drainage holes. Let the mix wick up water, remove it when the upper mix starts to moisten, and drain it fully. Use top watering sometimes to flush dissolved salts; never leave the pot permanently in water.
Should I mist Monstera leaves?
Misting cannot replace watering the potting mix. It provides only a brief local change in moisture, so pay attention to the room and the root zone separately. If foliage stays wet or develops spots, avoid repeated wetting and improve airflow.
What kind of water is best for Monstera?
Room-temperature water is a sensible starting point. Rainwater or suitable filtered water is useful where tap water is very hard; avoid softened water with added sodium. Let each watering drain freely regardless of the water source.
My Monstera droops while the soil is wet. Should I water it?
No. Check deeper soil, empty any standing water, and inspect drainage. If the plant continues to decline, look for soft tissue and damaged roots; adding more water to a wet pot can worsen the underlying problem.
How long can a Monstera go without water?
There is no reliable number of days for every plant. A small pot in bright light may dry much faster than a large pot in a dim room. Check moisture before a trip and arrange someone to inspect it if you will be away longer than its usual drying cycle.
Your next watering decision
Feel below the surface, compare the pot with its drained wet weight, and make sure the lower root zone is not still soggy. If it is ready, wet the mix evenly and let the runoff escape. If it remains wet, wait and investigate the pot setup before changing the calendar.
