Watermelon peperomia care

Peperomia argyreia

Thirsty’s starting schedule for Watermelon peperomia: about every 7 days. Check the soil and adjust it to your home.

Watering

Let the top of the soil dry to the touch before watering, and water less in winter. It has low water needs: overwatering causes root rot, though letting it get too dry makes it wilt. [1][2][3]

Light

Bright, indirect light; strong direct summer sun can scorch the leaves. [1][3]

Humidity

Copes with normal home humidity but prefers humid air, and benefits from a humidifier in winter. [2][3]

Soil and potting

A well-drained potting mix, such as a houseplant or cactus mix, or houseplant compost with added perlite. [2][3]

Pets

Non-toxic to cats and dogs. [4][1]
