🌱 How to Care for Weeping Fig to Prevent Powdery Mildew?

💧 How to Water

Water thoroughly when the top 2-3 inches of soil feel dry, typically every 7-14 days. Allow 75% of soil to dry between waterings. Reduce watering in winter. Very sensitive to overwatering - root rot and leaf drop occur quickly. Never let it sit in water.

☀️ Lighting

Thrives in bright, indirect light - ideal near east or west-facing windows. Can tolerate some direct morning sun but avoid harsh afternoon rays. Will not tolerate low light conditions. Grows toward light source, rotate regularly to maintain even shape.

🪴 Ideal Soil

Use well-draining, loam-based potting mix. A mix of regular potting soil with perlite and sand works well. Prefers slightly acidic pH (6.0-6.5). Good drainage is essential - never use heavy, compacted soil.
