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

💧 How to Water

Let the top 2-5cm (1-2 inches) of soil dry out between waterings, then water thoroughly until liquid drains from the pot. Never let the plant sit in standing water, as its roots are highly prone to rot.

☀️ Lighting

Place in bright, indirect light near an east- or west-facing window. The white sections of the leaves have no chlorophyll and can scorch in direct sun, but too little light causes new growth to revert to solid green.

🪴 Ideal Soil

Use a chunky, well-draining aroid mix -- a blend of standard potting soil, perlite, and orchid bark works well -- to keep oxygen at the roots and prevent rot.
