🌱 How to Care for Philodendron Gloriosum to Prevent Leaf Spot?

💧 How to Water

Water when the top 1 inch (2-3 cm) of the substrate is dry to the touch, approximately every 7 days in summer and less frequently in winter. Avoid waterlogging as it is very susceptible to root rot. Use chlorine-free water at room temperature.

☀️ Lighting

Place the plant about 3 feet from a south-facing window or directly in an east or west-facing window where it does not receive direct sun. It needs bright indirect light to maintain its characteristic colors and develop large leaves. Avoid full shade and direct sun exposure.

🪴 Ideal Soil

Use an airy aroid mix: combine orchid bark, perlite, and coconut coir or peat moss in equal parts. The substrate should drain quickly but retain some moisture. A pH between 5.0 and 7.0 is ideal. Avoid compact substrates that retain too much water.
