🌱 How to Care for Bird of Paradise to Prevent Anthracnose?

💧 How to Water

Water every 4–7 days in spring and summer, allowing the top 2–3 cm of soil to dry slightly between waterings. Reduce to once weekly in autumn and winter. Strelitzia has fleshy roots prone to rot — when in doubt, water less.

☀️ Lighting

Place in the brightest spot available indoors, ideally directly in front of or close to a south- or west-facing window. It tolerates some direct sun but protect from harsh midday summer rays. Low light will prevent flowering and slow growth significantly.

🪴 Ideal Soil

Use a rich, well-draining mix: a blend of quality potting compost, perlite, and orchid bark works well. Ensure the pot has drainage holes. Avoid heavy clay soils that retain too much moisture.
