How often should you water a pothos?
A pothos is one of the few plants that tells you when it’s thirsty: the leaves visibly droop and perk up again after a drink. Even so, it’s kinder to water before it gets that far — and there’s a way to know when.
At an east-facing window, in a 16 cm plastic pot, a pothos (also called devil’s ivy) needs water every 4 days in summer and every 7 in winter. Before each watering, push a finger into the soil: if the top two or three centimetres are dry, water; if they’re still damp, wait.
Why doesn’t every pothos need water on the same day?
A pothos (Epipremnum aureum) comes from the island of Mo’orea, in French Polynesia, where it scrambles up trees in humid tropical forest. It wants soil that stays faintly damp, never soggy, and it forgives a missed watering far more readily than a soggy one: gardeners generally agree it is safer a little dry than too wet. How often yours needs a drink comes down to how fast the soil dries in your pot, and three things set that speed:
- Light. More light means more work for the leaves and more water used. Beside a bright window the soil dries far sooner than in a dim corner.
- The pot. A big pot stores more water. Terracotta breathes and dries quickly; plastic and glazed ceramic keep moisture in.
- The season. Long, warm summer days keep a pothos drinking steadily; in winter it nearly idles, and one watering lasts a good deal longer.
Here are the numbers for one pothos, in one pot, in four different places around a home:
| Where it lives | In July | In January |
|---|---|---|
| South- or west-facing window | 4 days | 7 days |
| East-facing window | 4 days | 7 days |
| North-facing window | 7 days | 12 days |
| Hallway or corner with no window | 10 days | 17 days |
Swapping the pot shifts things as much as swapping the window. In the same morning light, a 25 cm plastic pot lets a pothos wait 7 days in July, while a 16 cm terracotta pot can only wait 3.
Does watering change if a pothos is in low light?
A lot. A pothos copes with shade, which is exactly why it ends up in dim hallways, and that is where overwatering does its worst: in low light the plant drinks little, the soil stays wet for days and the roots go without air. If your home is dark, have a look at the plants that cope best with low light and set the watering by the shade, not the calendar.
How can you tell when a pothos needs water?
Press a finger into the soil to the first knuckle. If the top two or three centimetres are dry, it’s time to water. If they still feel cool, give it another day or two and check again. Some growers let the soil dry out almost completely, and a pothos copes; a dry top couple of centimetres is simply a safe starting point.
A few extra clues help:
- The weight of the pot. Lift it straight after watering and again a few days on: dry soil makes it noticeably lighter.
- Drooping leaves. A pothos explains itself better than most houseplants: the gloss fades, the leaves hang, and a proper drink usually lifts them again within hours. Treat it as the last warning, not the first. One caution: roots sitting in soggy, airless soil make leaves droop too. If the soil is wet, hold off the watering can and lift the plant out to look at the roots.
What’s the right way to water a pothos?
- Soak the soil until water runs from the drainage hole. That wets it evenly all the way down.
- Empty the drip tray once half an hour has passed. Roots left standing in water rot.
- Use room-temperature water, not ice-cold from the tap. If your tap water is very hard, rainwater or filtered water is kinder to the plant.
- Skip the daily splash. It wets the surface and leaves the bottom dry, or soggy without you ever seeing it.
How do you tell overwatering from underwatering?
Too much: yellow leaves, permanently damp soil, a musty smell, fungus gnats around the pot, soft dark stems at soil level. This is the commonest slip. If it sounds familiar, read why pothos leaves turn yellow.
Too little: leaves drooping and curling, dry brown tips, hard soil shrinking from the sides of the pot. In that case, read why pothos leaves turn brown.
And in winter?
With less light and warmth, a pothos barely grows and drinks less: at the east-facing window, the gap stretches from 4 to 7 days. Central heating dries the air without always drying the soil, so let your finger decide before the watering can does, and keep the plant away from radiators and cold draughts. Hold off on feeding until spring.
Quick questions
Can I water a pothos from below? Yes, especially if the soil has dried so hard that water runs straight through. Stand the pot in a basin of water until the soil is evenly damp, then let it drain well.
Can a pothos live in water alone? It can, in a jar or glass, as long as you change the water when it clouds. In a pot, water it as above. See how to propagate pothos.
When does a pothos need a bigger pot? Roughly every two or three years, moving up just one pot size. A new pot changes the rhythm of watering, and the app allows for that.
How often should I recheck the routine? Whenever you move the plant or the season turns: the light changes, and the rhythm with it.
Who remembers the right day?
Knowing a pothos is watered “when the soil dries” is easy. Remembering the exact day at the end of a crowded week is harder, and with several plants on different schedules it’s impossible to hold in your head. Verdejar does the sums for each plant, using your light, your pot and the month, and nudges you on the day. The rest of the care is in how to care for a pothos.
