Pothos Care: How to Keep Your Vine Full and Healthy

Golden pothos (Epipremnum aureum), also called devil's ivy, is an evergreen vine in the arum family (Araceae). It is native to the Society Islands of French Polynesia and climbs with aerial roots². In the tropics, vines climb trees 15 m (50 ft) tall and grow lobed leaves up to about 90 cm (3 ft) long³. Indoors it usually keeps its heart-shaped juvenile leaves, which seldom pass 15 cm (6 in)²³.

At a Glance

Light

Pothos prefers bright, indirect light². An east- or west-facing window works, or a south-facing one behind a sheer curtain. Direct sun, especially in summer, can scorch the leaves¹.

Pothos survives long periods in low light² and tolerates levels as low as about 540 lux (50 foot-candles). At that level, new leaves stay small and variegated (patterned) types lose color. About 1,600 lux (150 foot-candles) or more keeps both color and leaf size³. Solid green 'Jade' is a good choice for dim rooms².

Watering

Water thoroughly, then wait until the top 4–5 cm (1.5–2 in) of soil is dry⁴. Check with a finger, not a calendar¹. Water less often in fall and winter⁴. In most homes, pothos does better a little on the dry side³.

Soggy mix, from watering too often or from a pot left standing in water, can rot the roots¹. Overwatering can also blacken leaf edges².

Temperature and Humidity

For best results, keep pothos at 18–30°C (65–86°F), away from cold drafts and radiators¹. UF/IFAS recommends 21–27°C (70–80°F) indoors. Several hours at 1–4°C (33–40°F), or an abrupt temperature change, can leave scattered brown patches in the center of leaves³.

Unlike many tropical houseplants, pothos does not need high humidity, so normal room air is fine¹. If winter heating makes the air very dry, a humidifier helps².

Soil, Pots and Repotting

Use an open, slightly acidic mix that holds some moisture but drains well, in a pot with drainage holes. A peat-free houseplant mix works. For your own blend, the RHS suggests 3 parts acidic (ericaceous) peat-free mix, 1 part grit and 1 part medium orchid bark¹.

Repot in spring once roots crowd the pot or grow through the drainage holes, roughly every 2 to 3 years. Go up only one pot size; a much larger pot stays wet and risks root rot¹. Wait about 4 weeks before repotting or feeding a newly bought plant³.

Feeding

Feed once a month from April to October with a general houseplant fertilizer, at the label rate¹. NC State Extension suggests every other month; both sources skip winter¹². Built-up fertilizer salts can damage leaves and roots, and running plenty of plain water through the pot may help³.

Pruning and Training

Older leaves yellow and drop over time, leaving most leaves near the stem tips². To keep the plant bushy, cut long stems back to just above a leaf. New shoots grow from the leaf joints, and the cut pieces make good cuttings¹.

Let stems trail, or train them up a moss- or coir-covered pole kept damp so the aerial roots grip it¹. With support and enough light, pothos starts producing larger, mature leaves². Wear gloves when pruning, because the plant can irritate skin¹².

Common Problems

• Older leaves turn yellow. Likely cause: soil kept too wet or too dry³; an occasional old leaf yellowing is normal aging². Fix: if the soil is wet, let the top 4–5 cm (1.5–2 in) dry before watering; if bone dry, water thoroughly⁴. See yellow leaves.
• Black leaf edges and soil that stays wet. Likely cause: overwatering and root rot². Fix: water less, and root a few healthy stem pieces as backups¹.
• Small, plain new leaves. Likely cause: too little light; in commercial growing, low fertilizer or magnesium can do the same. Fix: give it 1,600 lux (150 fc) or more of indirect light³.
• Dry, brown patches on the pale parts of leaves. Likely cause: direct sun or heat. Fix: move it out of direct sun and away from heat; damaged leaves will not recover³.
• Scattered brown patches in leaf centers after a cold spell. Likely cause: chilling at 1–4°C (33–40°F) or an abrupt temperature drop³. Fix: keep it at 18–30°C (65–86°F), away from drafts¹.
• Crisp, brown leaf tips. Possible causes: fertilizer salt buildup³ or dry heat from a radiator¹. Fix: flush the pot with plain water and move the plant away from heat. See brown leaf tips.
• White, cottony clumps or shell-like bumps on stems and leaves. Likely cause: mealybugs or scale insects². Fix: check plants often, and ask a local nursery or plant clinic about treatment if they spread.

Propagation

Pothos roots easily from stem cuttings, even in a glass of water¹².

1. Cut a piece of healthy stem just below a leaf joint, or node¹. Commercial growers root pieces as short as 2.5–4 cm (1–1.5 in), with one node and one leaf³.
2. Stand it in a glass of water in a bright spot, with the node under water¹.
3. Roots often show within 2 to 4 weeks²³.
4. Once roots appear, pot the cutting up in potting mix¹.

To layer a stem instead, pin it onto a pot of free-draining mix, and roots should form at the leaf joint¹.

How Plantalk AI Helps

In Plantalk AI, add your pothos with photo identification to get its ideal light and temperature ranges and a care schedule. Send the Plantie Assistant a photo of yellow leaves or a spot for step-by-step answers. The Plantiemoji sensor, sold separately, adds live light, temperature, humidity and soil moisture readings to the plant's Environment view. The app's answers are guidance, so for serious pest or disease problems, also ask a local nursery or plant clinic.

Common Questions

Can Pothos Live in Low Light?

Yes. It survives long periods in low light and tolerates about 540 lux (50 foot-candles)²³. New leaves will be smaller and variegated types fade, so solid green 'Jade' suits dim spots better²³.

Why Is My Pothos Losing Its Variegation?

Too little light is the usual cause¹²³. Variegated pothos needs about 1,600 lux (150 foot-candles) or more to keep its color³. Move it nearer a bright window, out of direct sun, and watch the new leaves¹³.

Is Pothos Toxic to Cats and Dogs?

Yes. The ASPCA lists it as toxic to cats and dogs because it contains insoluble calcium oxalates⁵. Signs include burning and irritation of the mouth, tongue and lips, excessive drooling, vomiting and trouble swallowing⁵. If your pet eats some, call your vet; in the US, ASPCA Poison Control is (888) 426-4435, and a fee may apply⁵.

Does Pothos Clean Indoor Air?

Not in a meaningful way. The idea grew from a 1989 NASA study of plants in small, sealed chambers⁶. Homes constantly exchange air and gain new pollutants, so even about 11 plants per square meter (1 per square foot) cannot keep up⁶.
