🌱 How to Care for Round-Leaf Aglaonema to Prevent Anthracnose?

💧 How to Water

Water thoroughly when the top 2 inches (5 cm) of soil feel dry, letting excess drain freely. Aglaonema rotundum dislikes both bone-dry and soggy soil - overwatering is the most common cause of root rot.

☀️ Lighting

Bright, indirect light keeps the pink veining vibrant; avoid direct sun, which scorches the leaves. It tolerates lower light but growth slows and coloration fades.

🪴 Ideal Soil

Use a loose, well-draining mix of potting soil, perlite, and orchid bark or coco coir. A slightly acidic pH (5.6-6.5) supports healthy root growth.
