How Often To Water Your Pothos (The Honest Answer)

There is no number. Not every ten days, not once a week, not every time someone on the internet tells you to. The honest answer to how often you should water your Pothos is: when the soil is almost completely dry. That’s it. That’s the rule. Everything else — the environment your plant is in, the pot it’s sitting in, the soil mix it’s growing in — just changes how quickly you arrive at that point.

If you want a rough ballpark to start from: in average indoor conditions, most Pothos need watering somewhere between every one and two weeks in summer, and every two to four weeks in winter. But treat that as a starting point, not a schedule, and you’ll do better once you understand what’s actually driving it.

Why “Once A Week” Is Useless Advice

The number of times “water your Pothos once a week” appears on the internet is frankly embarrassing. It is advice that sounds helpful but tells you absolutely nothing, because it ignores every single variable that actually determines how thirsty your plant is.

Your Pothos in a south-facing window in July might need watering every five days. Your Pothos in a dim corner in January might go three weeks between waterings. Give them both the same “once a week” schedule and you’ll have one that’s parched and one that’s drowning, and you’ll wonder why Pothos care is so confusing.

The only schedule that works is the one you build by actually checking your plant. Here’s everything that affects how quickly the soil dries out.

What Actually Determines Watering Frequency

Light

This is the biggest one. Pothos that are in bright light are photosynthesising actively and using up water much faster than plants sitting in low light. More light, more growth, more water used, soil dries out faster.

This is also worth knowing: putting your Pothos in low light specifically to avoid watering it is a bad trade. Low-light plants still need watering, they’re just slower about everything, including recovering from problems. A plant that’s underlit and underwatered is much more vulnerable to pests and disease than a well-lit, well-watered one. [More on that below.]

Temperature

Warmer rooms mean faster evaporation and a more active plant. A Pothos on a windowsill in summer is in a completely different environment to the same plant in the same spot in January. If you’re in the UK and you turn the central heating off for summer, your watering frequency can shift noticeably within a few weeks.

Pot Material

Terracotta pots are porous. They wick moisture out of the soil, which means the soil dries out significantly faster than it would in a plastic or ceramic pot. If you’ve moved your Pothos from a plastic nursery pot into a terracotta pot and suddenly feel like you’re watering it constantly, that’s why. Neither material is wrong, but they require different watering habits.

Pot Size

More soil holds more water. A Pothos in a generously sized pot will dry out more slowly than the same plant crammed into a small one. On the flip side, a tiny plant in a huge pot can sit in soggy soil for so long that root rot sets in before the soil ever properly dries out. Pot size matters more than most people think.

Soil Mix

Dense, peat-heavy shop-bought compost retains water for a long time. Chunky, bark-heavy mixes drain quickly and dry out fast. If you’re using a homemade aroid mix or have added perlite to your potting soil, expect to water more often than someone using a standard potting compost straight from the bag.

Humidity

Dry air speeds up evaporation from the soil surface. If you’re in a centrally heated home in winter (and if you’re in the UK, that’s most of us for about six months of the year), the air is probably very dry, and your soil will dry out more quickly at the surface, even if the roots are still getting moisture. This is one reason misting does nothing useful: it doesn’t affect the soil at all, and the humidity boost to the air lasts about as long as it takes the water to evaporate off the leaves, which is minutes.

Root Bound Plants

A Pothos that’s very root bound has a lot of roots and relatively little soil, which means the soil dries out very fast and the plant can get thirsty quickly even if you feel like you’re watering it constantly. If you’re watering what feels like every few days and the plant still looks droopy, this might be worth checking. [More on drooping here.]

How To Actually Know When To Water

Forget the “top inch of soil” test. It’s one of the most repeated pieces of plant advice on the internet and it’s genuinely not that useful, because what matters is what’s happening at root level, not what’s happening at the surface. Whether an inch down feels dry or damp depends entirely on your soil mix, your pot size, and whether you’re watering from the top or bottom. It’s not a reliable signal.

Here’s what actually works:

Start With A Moisture Meter

If you’re new to this, a moisture meter is worth every penny. Stick it into the middle of the pot and it’ll tell you what’s going on down near the roots where it actually matters. You’re aiming to water when the reading gets down to 2 or 3 out of 10, depending on the meter you’re using. Don’t water at 5. Don’t water at 7. Wait.

One caveat: moisture meters work well in standard shop-bought potting mixes. If your Pothos is in a chunky, bark-heavy, homemade mix, the meter can give unreliable readings because it’s making contact with air pockets rather than soil. In that case, switch to the method below.

Graduate To The Lift Test

Once you’ve watered your Pothos a few times and you know what the pot feels like when it’s freshly watered versus bone dry, you can ditch the meter and just pick the pot up. Dry soil is dramatically lighter than wet soil. The weight difference is obvious once you know what you’re feeling for, and the lift test is the fastest, most reliable method once you’ve got a feel for it.

This is genuinely how experienced plant keepers do it: you pick the pot up, you know immediately whether it needs water, you put it down. No tools required.

Slide It Out If You’re Not Sure

If you’re genuinely unsure, you can slide the root ball out of the pot and have a look. Dry roots are pale, almost white or light tan. Damp roots are darker. It sounds dramatic but it’s perfectly fine to do occasionally, and it gives you a completely accurate picture of what’s going on.

When To Water (The Actual Rule)

Water when the soil is almost completely dry, right through to the bottom of the pot. Not when the top inch is dry. Not on a schedule. Not when the plant looks a bit sad, because by the time it’s visibly drooping, you’ve left it a bit too long.

That last point is important.

⚠️ Don’t Wait For The Droop Letting your Pothos get so dry that the leaves start to droop before you water it isn’t just stressful for the plant, it’s actively inviting pests. Stressed plants release stress hormones, and those hormones act as a signal to pests like spider mites that a vulnerable host is available. You won’t see the pests arrive in real time, but consistently pushing your Pothos to the drooping point makes infestations significantly more likely. Water before it droops, not after.

How To Water Properly

When you do water, water thoroughly. This means adding water until it flows freely out of the drainage holes at the bottom, not just dampening the top layer of soil. You want the entire root zone to get moisture, not just the top third.

Then don’t water again until the soil has dried out properly.

This “drench and dry” approach is far more effective than giving your Pothos small amounts of water frequently. Small, regular top-ups encourage shallow roots to stay near the surface where they’re vulnerable to drying out quickly. A good thorough soak followed by a proper drying period encourages roots to grow deeper into the pot, where conditions are more stable.

If you find water is running straight through the pot and out the bottom very quickly without seeming to soak in, your soil may have become hydrophobic, which is what happens when soil gets very dry and starts to repel water rather than absorb it. The fix is to soak the whole pot in a basin of water for 15 to 30 minutes so it can rehydrate slowly. Full details in the underwatered Pothos guide.

Watering In Different Seasons

Your Pothos does not grow at the same rate all year, and its watering needs change accordingly.

In spring and summer, growth is active, light levels are higher (in most homes), and the plant is using more water. Watering every one to two weeks is typical, but check the soil rather than counting days.

In autumn and winter, growth slows right down, light levels drop, and your Pothos needs watering much less often. Overwatering is far more common in winter because people don’t adjust their habits when the seasons change. If you watered every ten days in summer, you might need every three weeks in winter. Check the soil. Don’t assume. [Full guide to watering in winter here.]

Common Watering Mistakes

Watering On A Schedule

Already covered this but it bears repeating: your plant doesn’t know what day it is. Check the soil, not the calendar.

Watering A Little And Often

Small, frequent waterings that never quite soak through are one of the most common ways to accidentally half-kill a Pothos. The top of the soil looks damp so you think you’ve watered, but the roots in the bottom half of the pot are bone dry. Water thoroughly every time, then wait until it’s almost dry before you do it again.

Not Having Drainage

If your pot doesn’t have drainage holes, water has nowhere to go and just sits at the bottom, where it rots roots. Pothos need drainage. If you love a pot that doesn’t have holes, use it as a cachepot (a decorative outer pot) and keep your Pothos in its nursery pot or a plastic pot with drainage holes inside it.

Watering At The Wrong Time Of Year

Keeping a summer watering schedule through winter is a fast track to overwatered, unhappy Pothos. Slow down in autumn and don’t pick back up until you see active growth again in spring.

Using Cold Water

Not a disaster, but worth mentioning. Cold water can mildly shock roots, and if you’re in an area with very cold tap water, letting it sit for a bit before watering isn’t a bad habit to get into. Room temperature water is fine. Boiling is not. [More on water type here.]

Signs You’re Getting It Wrong

Signs of underwatering:

• Soil is bone dry and pulling away from the pot sides
• Leaves drooping, looking dull, or curling at the edges
• Pot feels very light
• Water runs straight through without soaking in
• Little to no new growth

[Full guide to fixing an underwatered Pothos here.]

Signs of overwatering:

• Soil is consistently damp and never seems to dry out
• Yellow leaves (especially lower ones)
• Leaves drooping even though the soil is wet
• Mushy stems at the base
• Soil smells unpleasant

[Full guide to fixing an overwatered Pothos here.]

Both under and overwatering can cause drooping and yellow leaves, which is why checking the soil is always the first step before you do anything else.

What About Self-Watering Pots?

If you know yourself and you know that keeping on top of watering is not your strong suit, self-watering pots are a brilliant option. They work via a reservoir that the plant draws from as needed, so the roots get water when they want it rather than when you remember. [More on whether self-watering pots are worth it for Pothos here.]

Watering FAQs

How often should I water my Pothos in summer?

In summer, most Pothos in average indoor conditions need watering every one to two weeks, but this varies hugely with light, pot size, and soil mix. Check the soil rather than counting days.

How often should I water my Pothos in winter?

Much less often. Expect to water every two to four weeks in winter, sometimes longer. Growth slows right down in low light and cool temperatures, and the soil stays moist for much longer. Keep checking rather than keeping a schedule.

Should I water my Pothos from the top or bottom?

Both work. Top watering is fine as long as you water thoroughly and let the excess drain away. Bottom watering (sitting the pot in water and letting it soak up from the drainage holes) is great for making sure the whole root zone gets moisture and is particularly useful if your soil has started to repel water. [Full bottom watering guide here.]

Can I use tap water on my Pothos?

Yes. Tap water is absolutely fine. If you can drink it, your Pothos can too. There’s a persistent idea that fluoride or chlorine in tap water damages plants, but Pothos are not sensitive enough for this to be a real concern in practice. [More on tap water vs filtered water here.]

Why is my Pothos drooping even though I just watered it?

If your Pothos is drooping shortly after watering, overwatering is the more likely culprit. When roots have been sitting in waterlogged soil and start to rot, they can’t function properly, so the plant can’t take up water even when there’s plenty of it. Check the roots for rot and, if necessary, [read the overwatered Pothos guide]. It could also be that your soil has become hydrophobic and water isn’t actually reaching the roots when you water — in which case, [soak the pot properly].

Will my Pothos die if I forget to water it?

Probably not, once. Pothos are very forgiving and can tolerate a period of drought much better than they tolerate consistent overwatering. Forget to water once and the worst you’ll likely deal with is some drooping that corrects itself within a day of watering. Forget repeatedly and you’ll get root damage, stalled growth, and an invitation to every pest in the postcode. Don’t make a habit of it.

Why are my Pothos leaves turning yellow?

Yellow leaves can be a sign of overwatering, underwatering, too little light, or natural leaf turnover if it’s just the oldest leaves. [Full guide to yellow Pothos leaves here.]
