🌱 How to Care for Roselle to Prevent Mealybugs?

💧 How to Water

Water deeply once a week, or when the top 2–3 cm of soil is dry. Roselle tolerates brief dry spells but performs best with consistent moisture. Avoid waterlogging — ensure the pot or bed drains well to prevent root rot.

☀️ Lighting

Roselle demands full sun — at least 6–8 hours of direct sunlight daily. In lower light conditions the plant becomes leggy, produces fewer flowers, and calyx yield decreases significantly. Plant in the sunniest spot available.

🪴 Ideal Soil

Use well-draining loamy soil enriched with compost or aged manure. A pH of 6.0–7.0 is ideal. Avoid heavy clay soils that retain excess moisture. Adding perlite or coarse sand to the mix improves drainage and aeration.
