Just arrived? Your first week at home

  1. Unbox it gently; the leaf stems are a bit brittle and can snap.
  2. Place it in bright, indirect light, away from direct afternoon sun, heat vents and cold drafts.
  3. Check the soil: water only if the top inch or two is dry; peperomias hold water in their leaves and are fine to wait a few days.
  4. A droopy or yellow leaf after shipping is normal; remove any that fall or turn fully yellow.
  5. Don't repot for at least 2 weeks.
  6. If a leaf snaps off in transit, save it; you can use it to grow a new plant.

Light

Bright, indirect light keeps the stripes crisp, such as a few feet from an east window or near a west window behind a sheer curtain. It tolerates medium light but may stretch and lose some contrast. Avoid strong direct sun, which can scorch the leaves. The variegated form needs a bit more light to keep its cream edges.

Water

Water when the top inch or two of soil is dry, roughly every 1 to 2 weeks. The thick leaves store water, so it prefers to dry out slightly between drinks. Soft, wrinkled or droopy leaves with dry soil mean thirst. Yellow, mushy leaves or black stems at the soil line mean overwatering, the most common problem.

Humidity

Average home humidity is fine, though it appreciates a bit more. Grouping it with other plants helps if leaves get crispy in winter.

Temperature

Keep it between about 65 and 80 degrees F. Keep it away from cold drafts and windows in winter, and don't let it drop below about 55 degrees F.

Soil & repotting

Use a light, chunky, well-draining mix, such as indoor potting soil with lots of perlite or orchid bark. Peperomias have small root systems and like snug pots, so repot only every 2 to 3 years, one size up, in a pot with drainage.

Feeding

Feed monthly in spring and summer with a balanced liquid fertilizer at half strength. Skip feeding in fall and winter.

Troubleshooting common problems

  • Drooping, mushy stemsoverwatering and root rot. Let the soil dry more, and repot in fresh, chunky mix if roots are brown and soft.
  • Wrinkled or curling leavesunderwatering. Give it a thorough drink when the soil is dry.
  • Faded stripes or leggy stemsnot enough light. Move it closer to a bright window.
  • Brown spots on leavessunburn or water sitting on leaves. Move out of direct sun and water at the soil.
  • Dropped leavescold drafts or sudden changes. Keep it warm and in a steady spot.

Tips to help it thrive

  • Propagate from a single leaf: cut a leaf in half across the stripes, set the cut edge in moist soil, and baby plants will sprout in a few weeks.
  • Bottom-watering helps keep water off the leaves and stems.
  • The variegated form grows a bit slower; give it your brightest filtered spot.

Pet safety

Watermelon Peperomia is listed as non-toxic to cats and dogs by the ASPCA. As with any houseplant, it's still best to discourage pets from chewing the leaves, which can cause a mild upset stomach.
