Your Pilea peperomioides will thrive in bright, indirect light. Avoid harsh sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry, and allow excess water to drain completely to prevent root rot. Reduce watering in winter or lower-light conditions. Average room humidity is sufficient, but occasional misting can be beneficial. Choose a well-draining potting mix and fertilize monthly during the growing season (spring and summer) with a diluted balanced liquid fertilizer. With proper care, your Pilea peperomioides will reward you with its delightful coin-shaped foliage for years to come, and may even surprise you with the occasional "baby" plant sprouting up!
