Aluminium plant (Pilea cadierei) care

Vines & trailers · easy to keep

Last updated 26 October 2026

Aluminium plant (Pilea cadierei) wants bright indirect light. Water it every 6 days. Keep the compost lightly damp and never let it dry out completely — it wilts quickly. Pot it in light and free-draining — compost with plenty of perlite, or an aroid mix. A weak balanced feed monthly in spring and summer, and repot once a year. Humidity: room humidity is fine for most; the trailing kinds prefer above 60%. The ASPCA lists it as non-toxic to cats and dogs.

The aluminium plant: quilted dark-green leaves with raised silver patches that look painted on. A fast, bushy grower that turns leggy within a year or two, so pinch it back often and root the tips to keep the pot full.

Watering an Aluminium plant

Water every 6 days. Keep the compost lightly damp and never let it dry out completely — it wilts quickly.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright indirect light, and turn the pot weekly — a pilea leans hard toward its light source and goes permanently lopsided otherwise.

Humidity and temperature

Room humidity is fine for most; the trailing kinds prefer above 60%. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Peperomias have small, shallow root systems and semi-succulent leaves. A light, airy mix in a small pot is the whole secret; a big pot of wet compost is the whole problem.

Feeding

A weak balanced feed monthly in spring and summer. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot once a year. Rarely, and into a pot barely bigger than the last. Peperomias are happiest tight.

Common problems

Leaning heavily to one side
It grows toward light faster than most.

Fix: Turn the pot a quarter turn every week.

Leggy, stretched growth: how to read it on any plant
Yellow lower leaves dropping
Overwatering, or simply age as the stem lengthens.

Fix: Let it dry out more between waterings; a bare lower stem on an older pilea is normal.

Yellow leaves: how to read it on any plant
Curling or cupping leaves
Usually too much light; sometimes too little water.

Fix: Move it out of direct sun and check the compost.

Propagation

Stem cuttings with a node root in water or damp compost within a few weeks.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Non-toxic to cats and dogs.

The ASPCA lists Aluminum Plant (Pilea cadieri) as non-toxic to cats and dogs (checked 26 October 2026).

If your pet has eaten a plant, call your vet, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661. Both are open around the clock and may charge a consultation fee. Take the plant or its label with you.

This is general information, not veterinary advice. We don't test plants: what we say about toxicity follows the ASPCA's published plant list as it stood on 26 October 2026, and that list can change. "Non-toxic" means not poisonous — a pet that eats enough of any plant can still vomit, and fertiliser, pesticide or leaf shine on a plant can harm it. It also only helps if the plant is what you think it is. It covers cats and dogs only; ask your vet about rabbits, birds, reptiles or anything else, and a doctor about children. Read our terms.
