🌱 How to Care for Spotted Evergreen to Prevent Anthracnose?

💧 How to Water

Water when the top inch of soil feels dry — approximately every 7–10 days in summer, less in winter. Always use room-temperature water. Aglaonema costatum is sensitive to fluoride, so filtered or rainwater is preferred.

☀️ Lighting

Thrives in low to medium indirect light — ideal for north or east-facing windows. It tolerates shade better than most houseplants, but avoid deep shade as variegation may fade. Never expose to direct sunlight, which scorches the decorative leaves.

🪴 Ideal Soil

Use a well-draining mix of peat/coco coir, perlite, and regular potting soil in a 1:1:2 ratio. Ensure the pot has drainage holes. Slightly acidic pH of 5.6–6.5 is ideal. Repot every 2 years or when roots emerge from drainage holes.
