🌱 How to Care for Metallic Peperomia to Prevent Leaf Spot?

💧 How to Water

Let the top two to three centimetres of soil dry out, then water thoroughly and drain. Water less in winter, and keep water off the leaves, which shed it and can spot.

☀️ Lighting

Bright, indirect light keeps the leaves deeply coloured and metallic. Avoid direct sun, which scorches and fades them, and very low light, which dulls the plant and slows growth.

🪴 Ideal Soil

Use a light, very free-draining mix such as peat or coir with plenty of perlite and coarse sand. Heavy, water-retentive soil invites root rot.
