🌱 How to Care for Pink Princess Philodendron to Prevent Bacterial Leaf Spot?

💧 How to Water

Water thoroughly when the top 2-5 cm (1-2 in) of soil feels dry, then let the pot drain completely. Overwatering is the leading cause of root rot in this species, so always use a pot with drainage holes.

☀️ Lighting

Bright, indirect light for at least 10-12 hours a day brings out the strongest pink variegation. Avoid direct sun, which can scorch the leaves, and avoid deep shade, which causes the plant to revert to solid green.

🪴 Ideal Soil

Use a light, well-draining, peat-based mix (peat or coco coir with perlite and orchid bark) that holds some moisture without staying soggy. Slightly acidic to neutral pH is ideal.
