🌱 How to Care for Philodendron to Prevent Thrips?

💧 How to Water

Water when the top 1–2 inches of soil feel dry, approximately once a week in spring/summer and every 10–14 days in fall/winter. Use room-temperature water and ensure thorough drainage to prevent root rot.

☀️ Lighting

Philodendrons prefer bright to medium indirect light — ideally near an east- or north-facing window. They tolerate lower light but will grow slower with smaller leaves. Avoid direct afternoon sun, which scorches foliage.

🪴 Ideal Soil

Use a well-draining aroid mix: combine a quality peat or coco coir-based potting mix with perlite and/or orchid bark. Good drainage is critical to prevent root rot. A slightly acidic to neutral pH of 5.5–7.0 is ideal.
