Aluminum Plant

Aluminum Plant key facts

Growing Difficulty

Beginner-friendly

Lifespan

Perennial (evergreen)

Size

About 20-30 cm in pots; up to about 60 cm

Watering

Light houseplant feed in the growing season

Light & Placement

Bright indirect light; avoid full sun, which scorches the leaves.

Watering

Water moderately in the growing season and less from autumn through winter. Overwatering or poor drainage commonly causes root rot.

Temperature & Overwintering

A tender tropical plant. Keep it in a warm, humid room in winter.

Soil & Repotting

Use a peaty, soil-based mix. It likes humidity, so a humidified room or a tray of wet pebbles helps.

Propagation

Pinch stem tips to keep it compact. Young plants have the best foliage, so some growers replace plants each spring from cuttings.

Pests & Cautions

Watch for mealybugs, scale, aphids and spider mites. Powdery mildew can appear in high humidity with poor air flow. It is listed as non-toxic to dogs, cats and horses.

About Aluminum Plant

Pilea cadierei, the Aluminum Plant, is a compact, easy-care evergreen perennial with silver-marked dark green leaves, growing 20 to 30cm tall, and safe to keep around dogs and cats.

7 things to know before growing Aluminum Plant

1. 1Bright, Indirect Light

   Prolonged direct sun can scorch the leaves, so place your plant near a window with filtered light, such as behind a sheer curtain. Too little light, though, can cause the silvery markings to fade, so aim for a bright spot rather than deep shade.

2. 2Water When Soil Dries

   Water thoroughly, letting excess drain from the bottom of the pot, but only once the soil surface has dried out. Overwatering is the most common cause of root rot, so always empty any water left in the saucer.

3. 3Use Well-Draining Soil

   A standard houseplant potting mix amended with about 10-20% perlite or pumice provides the drainage this plant prefers. Avoid soil mixes that hold too much moisture, since Pilea cadierei is sensitive to constantly wet roots.

4. 4Repot Every 1-2 Years

   Because it grows fairly vigorously, repotting into a slightly larger pot every one to two years helps prevent the roots from becoming crowded. Spring through early summer, when temperatures are stable, is the best time to do this.

5. 5Keep Warm in Winter

   This plant is sensitive to cold, so move it to a warm spot indoors as temperatures drop. Growth naturally slows in winter, so cut back on watering frequency during the cooler months.

6. 6Pinch Back Leggy Stems

   Stems can stretch and become leggy over time, so pinching or trimming back overgrown growth helps the plant keep a fuller, bushier shape. Trimmed stem cuttings can also be rooted to propagate new plants.

7. 7Choosing a Healthy Plant

   Look for a plant with firm, plump leaves and clearly defined silver markings. Avoid plants with yellowing leaves or long, leggy stems, as these can be signs of stress or insufficient light.
