🌱 How to Care for Alternanthera to Prevent Grey Mould?

💧 How to Water

Water when the top 2-3 cm of soil is dry, usually once or twice a week in hot weather and less in winter. Do not let it dry out completely, as it wilts fast, and empty the saucer after watering so the roots do not rot.

☀️ Lighting

Full sun or light shade outdoors; 6 hours of sun gives the strongest colors, though in very hot summers midday sun can bleach the leaves. Indoors, keep it by the brightest window. In low light it gets thin, leggy and greener.

🪴 Ideal Soil

Fertile, well-drained soil rich in organic matter, slightly acidic to neutral. In pots, use houseplant compost with some perlite or coarse grit.
