🌱 How to Care for Corn Plant to Prevent Fusarium Wilt?

💧 How to Water

Allow the top 75% of soil to dry between waterings. Use distilled or rainwater as this plant is sensitive to fluoride and chemicals in tap water. Reduce watering in winter when growth slows. Yellow leaves often indicate overwatering.

☀️ Lighting

Prefers medium to bright indirect light but tolerates low light. Avoid direct sunlight which can scorch leaves. Variegated varieties need more light to maintain their coloring. Brown spots indicate too much light; slow growth indicates too little.

🪴 Ideal Soil

Use well-draining, loamy potting soil with a pH of 6.0-6.5. A mix of peat moss, perlite, and standard potting soil works well. Good drainage is essential to prevent root rot.
