🌱 How to Care for Purple Sword to Prevent Aphids?

💧 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.
