Introduction

Pilea cadierei, otherwise known as the Aluminum Plant, is a tropical evergreen native to Southeast Asia. It is a popular houseplant loved for its bright green leaves with striking silver stripes and splashes that give it an almost metallic sheen.  The Aluminum Plant has basic requirements making it suitable for both beginner and experienced gardeners: ample light, much humidity, regular watering when the soil feels dry (but not soggy), and temperatures between 65-75°F (18-23°C). While this plant requires little effort or attention to thrive indoors, it still makes an excellent statement piece that brings life into any living space.

Aluminum Plant Care

The Aluminum Plant is an easy houseplant that requires moderate care to thrive. This plant prefers bright, indirect light, well-draining soil, and moderate watering. They enjoy a warm, humid environment, with temperatures between 60 to 75 degrees Fahrenheit. Regular feeding with a balanced houseplant fertilizer during the growing season will help promote robust growth, but feeding should be reduced during the dormant winter months.

Light

Aluminum Plants require bright, indirect light to keep their vibrant silver markings. However, they don't tolerate direct sunlight, which can burn and fade their leaves. If you notice the plant's silver color fading, it could be a sign that it's not getting enough light.

Soil

A well-draining, peat-based potting mix is ideal for Aluminum Plants. The soil should retain some moisture but not become waterlogged. You can create your own mix by combining two parts peat moss with one part perlite or sand.

Water

When it comes to watering, Aluminum Plants prefer evenly moist soil, but not waterlogged. Water the plant thoroughly and allow the top inch of soil to dry out before watering again. Overwatering can lead to root rot, a common issue with many houseplants. In the winter, the watering frequency should be reduced, allowing the soil to dry out a bit more between watering.

Temperature and Humidity

Aluminum Plants enjoy a warm, humid environment. They prefer temperatures between 60 to 75 degrees Fahrenheit and will not do well in temperatures below 60 degrees Fahrenheit. To increase humidity, you can mist the plant regularly, place it on a pebble tray filled with water, or keep it in a naturally humid room like a bathroom or kitchen.

Fertilizer

Feeding your Aluminum Plant with a balanced houseplant fertilizer will promote robust growth. Fertilize every two weeks during the growing season (spring to summer), following the instructions on the fertilizer package. It's advisable to reduce feeding during the dormant winter months to once a month or entirely stop it until spring.
