How to Care for Pilea

The Pilea genus comes from southern China, growing wild in the Yunnan and Sichuan provinces at the foot of the Himalayas, where it lives in shaded, damp, rocky forest. It spread around the world almost entirely through cuttings passed between friends rather than through the nursery trade, which is part of its charm and also a good hint about how easily it propagates.

The wider Pilea genus is enormous, with hundreds of species worldwide including the aluminium plant and the trailing Pilea glauca, and they all appreciate broadly similar treatment.

How Much Light Does Pilea Need?

Pilea wants bright, indirect light. A spot near an east-facing window, or set back a little from a south or west facing one, is ideal.

Keep it out of strong direct sun, which scorches those flat leaves and leaves pale bleached patches. Too little light causes a different problem: the stem stretches, the leaf stalks grow long and floppy, and the plant leans heavily towards the window. Turning the pot a quarter turn every week is genuinely worth doing with a Pilea, because it chases light more obviously than most plants and will grow lopsided if you leave it.

How Often Should You Water Pilea?

Water when the top 2 to 3cm of compost feels dry. In spring and summer that usually means once a week, dropping to every ten to fourteen days over autumn and winter.

Pilea is quite good at telling you when it is thirsty, because the leaves droop and lose their firmness, then recover within hours of a drink. Try not to let it get that far every time, though. Water thoroughly until it runs from the drainage holes, then let the pot drain fully and never leave it sitting in a saucer of water. Soggy compost is the main cause of problems with this plant.

What Humidity Does Pilea Need?

Pilea is comfortable at 40% to 50% humidity, which most homes provide without any help.

Its native forest habitat in southwest China is damp but temperate rather than steamy tropical, so it has never needed the high humidity that rainforest plants do. The leaves are thick and slightly waxy, which helps them hold moisture in. There is no need for a humidifier or a pebble tray. If your home gets very dry in winter you may see the occasional brown leaf edge, and grouping plants together is enough to sort that out.

What Temperature Does Pilea Need?

Pilea grows best between 18°C and 24°C, and it is happier in a slightly cooler room than most tropical houseplants.

The lowest temperature it can withstand is around 10°C. Below that growth stops and the leaves can yellow and drop, and prolonged cold combined with damp compost will rot the stem at soil level. Keep it away from draughty doorways and freezing window glass in winter, which matters because a bright windowsill is exactly where most people put one.

How Do You Propagate Pilea?

This is the easiest plant on the list to propagate, and it does most of the work for you.

A healthy Pilea constantly produces pups, which are small baby plants. Some push up through the compost from the roots, and others sprout directly from the main stem. Once a pup is around 5 to 8 cm tall with a few leaves of its own, it is ready to separate.

For pups coming up from the compost, push your finger down beside the pup and follow its stem below the surface, then cut it away from the parent root with a clean sharp knife, taking any roots that come with it. Pot it straight into a small pot of free draining compost and keep it lightly moist.

For pups growing off the main stem, cut them off flush against the stem. These usually have no roots, so stand them in a small glass of water for two to three weeks until roots appear, then pot them up. Either way the success rate is very high, which is exactly why this plant has been passed around so widely.

Why Are My Pilea Leaves Turning Yellow?

Overwatering is the most common cause. Yellow lower leaves that feel soft, with compost that stays damp for days, mean the roots are waterlogged. Let the top few centimetres dry before watering again and check the pot drains freely. If the main stem is soft or dark at soil level, rot has set in, and your best move is to remove any healthy pups immediately and root them as replacements.

The other likely explanation is simply age. Pilea naturally sheds its oldest lower leaves as the stem lengthens, so a leaf or two yellowing at the bottom while new leaves keep unfurling at the top is completely normal. Over time this is how a Pilea develops its characteristic bare stem.

Rule out the rest quickly. Yellowing with dry, shrunken compost and drooping leaf stalks means underwatering, so soak it thoroughly. Pale, bleached yellow leaves mean too much direct sun. Slow general yellowing through the growing season means it needs feeding, so use a balanced liquid houseplant feed monthly in spring and summer. And curling or cupping leaves, which people often notice alongside yellowing, usually point to inconsistent watering or too much light rather than anything serious.

To keep a Pilea looking its best, rotate the pot regularly, remove yellowing leaves cleanly at the base of the stalk, repot every year or two in spring, and pot up the pups as they appear so the parent plant keeps its energy for its own growth.
