🌱 How to Care for Peperomia Rosso to Prevent Fungus Gnats?

💧 How to Water

Water when the pot feels light and the top 2-3 cm of mix are dry; in practice about once a week in the growing season and every 2-3 weeks in winter. Water at the soil, not into the rosette, and empty the saucer. Overwatering is the main killer: limp stems, dropped lower leaves or small corky bumps under the leaves mean it is getting too much.

☀️ Lighting

Bright, indirect light brings out the strongest red. A spot near an east window or behind a sheer curtain is ideal; it also does well under grow lights or office lighting. Strong direct sun can bleach or scorch the leaves, and too little light makes the rosette stretch and lose color.

🪴 Ideal Soil

Use a light, airy potting mix that drains fast, such as houseplant mix with perlite, pumice or orchid bark. Its fine roots rot in dense, wet soil, so always use a pot with drainage holes.
