ðą How to Care for Ventricosa Pitcher Plant to Prevent Cercospora Leaf Spot?
ð§ How to Water
Keep the sphagnum moss or peat-based substrate evenly moist at all times, but never waterlogged. Use only distilled, reverse-osmosis, or rainwater - tap water minerals build up in the pitchers and roots and can kill the plant over time.
âïļ Lighting
Provide bright, indirect light for 12-14 hours a day; an east- or south-facing window with a sheer curtain works well. Direct midday sun can scorch the leaves, while too little light produces pitcher-less vines.
ðŠī Ideal Soil
Pot in a low-nutrient, well-draining mix of long-fiber sphagnum moss and perlite (roughly 1:1). Never add potting soil, compost, or standard fertilizer - regular nutrients damage the roots.
