This plant loves bright, indirect light and it’ll tolerate some medium light. It’s definitely not suited to intense, direct sunlight.
Water Pilea Moon Valley once or twice a week. You’ll want to keep it evenly moist, picking up that watering can as soon as the soil starts to dry out. It will tolerate average home humidity but prefers high humidity. So if you have a dry house and/or it’s wintertime, consider putting the plant on a pebble tray to keep the humidity up. Pilea plants should be repotted every couple years.
