🌱 How to Care for African Violet to Prevent Damping Off?

💧 How to Water

Water from the bottom by placing the pot in a saucer of room temperature water for 15-30 minutes. Never let water sit on leaves as it causes permanent spotting. Avoid crown rot by keeping the center dry.

☀️ Lighting

Place in bright, indirect light near a north or east-facing window. Avoid direct sunlight which scorches leaves. Can thrive under fluorescent grow lights for 10-12 hours daily.
