🌱 How to Care for Compact Corn Plant to Prevent Bacterial Leaf Spot?

💧 How to Water

Water only once the top half of the soil feels dry, typically every 10-14 days in summer and every 3 weeks in winter. Use filtered or rested (24h) water since the plant is sensitive to fluoride and chlorine, which cause brown leaf-tip burn.

☀️ Lighting

Thrives in medium to bright indirect light and tolerates low light. Avoid direct sun, especially afternoon sun, which scorches and bleaches the leaves.

🪴 Ideal Soil

Use a light, well-draining potting mix of peat/coco coir, pine bark, and perlite. Avoid soggy soil, which encourages root rot.
