🌱 How to Care for Golden Pothos to Prevent Pythium Root Rot?

💧 How to Water

Water when the top inch of soil is dry, approximately every 8-9 days. The plant will droop slightly when thirsty, giving you a visual cue. Reduce watering in winter. Avoid overwatering as it can cause root rot.

☀️ Lighting

Thrives in bright, indirect light but tolerates low light conditions well. Avoid direct sunlight which can burn leaves. Variegated varieties need more light to maintain their patterns. Works well under fluorescent lighting.

🪴 Ideal Soil

Use well-draining potting soil with a pH of 6.1-6.8. Add perlite or pumice to improve drainage. A mix of regular potting soil with perlite works well.
