🌱 How to Care for Sweet Pitcher Plant to Prevent Grey Mould?

💧 How to Water

Keep the soil constantly damp to wet -- stand the pot in a shallow tray with about 2-3 cm of water and never let it dry out. Always use rainwater, distilled water, or reverse-osmosis water; tap or mineral water contains salts that can kill it. Reduce watering slightly in winter dormancy but never let the mix go bone dry.

☀️ Lighting

Provide full sun -- at least 6 hours of direct light daily. Indoors, it needs a very bright south-facing window or supplemental grow lights for 12-16 hours a day; too little light causes weak, floppy pitchers and poor red coloration.

🪴 Ideal Soil

Use a nutrient-free, acidic mix of 2 parts sphagnum peat moss to 1 part lime-free horticultural sand or perlite. Never use regular potting soil, compost, or fertilizer -- both will damage the roots and disrupt the plant's natural feeding process.
