Diagnosing Browning in Drosera Capensis: Light, Water, Pests, and Soil

Drosera capensis is a full-sun plant—300W grow lights at 8 inches shouldn't cause burn unless heat buildup exceeds tolerance. If only older leaves brown while center shows green growth, this is normal rapid leaf turnover creating layered dead growth.

Potential Problems If All Leaves Brown

• Water: Use only distilled, RO, or rain water—never tap or drinking water. Maintain constant moisture via tray method without waterlogging.
• Pests: Invisible insects may damage leaves. Treat with pyrethrins, neem oil, or non-soap natural insecticides.
• Soil: Requires 50/50 sphagnum peat moss and perlite. Long-fiber sphagnum acceptable with perlite/silica sand drainage.
• Terrarium Risks: Enclosed environments promote mold and root rot. Grow as standard potted plants near windows or under lights.
