🌱 How to Care for Purple Sword to Prevent Grey Mould?
💧 How to Water
Water when the top 2-3 cm of soil has dried out, roughly every 7-10 days; reduce frequency in winter and never let the pot sit in standing water.
☀️ Lighting
Give it bright, indirect light near an east or filtered south/west window; direct midday sun will scorch the thin leaves, while deep shade causes leggy, weak growth.
🪴 Ideal Soil
Use a chunky, fast-draining aroid mix (potting soil, perlite or pumice, and orchid bark) so roots get air and excess water escapes quickly.
