🌱 How to Care for Heartleaf Philodendron to Prevent Sooty Mold?

💧 How to Water

Water thoroughly when the top 1-2 inches (2-3 cm) of soil feel dry to the touch, usually every 7 days in summer and every 10-14 days in winter. Allow excess water to drain freely. Never let the plant sit in standing water, as this leads to root rot. Use room-temperature water.

☀️ Lighting

Place in bright, indirect light near an east- or west-facing window for best growth. The heartleaf philodendron tolerates lower light conditions better than most houseplants, but growth will slow and leaves will be smaller. Avoid direct sun, which can scorch the leaves.

🪴 Ideal Soil

Use a well-draining, rich, organic potting mix. A blend of potting soil, perlite, and orchid bark (2:1:1) works excellently. Target a soil pH of 6.0-7.0. Repot every 2 years in spring when roots start emerging from drainage holes.
