🌱 How to Care for Calabash Tree to Prevent Mealybugs?

💧 How to Water

Established calabash trees are drought-tolerant; water deeply every 10–14 days and allow the top layer of soil to dry out slightly between waterings. Container-grown specimens need more frequent checks — water when the top 2–3 cm of substrate feel dry. Avoid waterlogging, which promotes root rot. During fruiting (6-month cycle), maintain consistent soil moisture to support fruit development.

☀️ Lighting

Crescentia cujete requires full sun — a minimum of 6 hours of direct sunlight per day. It will tolerate partial shade but produces fewer flowers and fruits. In regions with extremely intense afternoon heat, light afternoon shade can prevent leaf scorch on young trees.

🪴 Ideal Soil

Plant in well-draining soil with good fertility. Sandy-loam or loam-based mixes enriched with organic matter work best. The tree tolerates a wide pH range from 6.0 to 8.5. Avoid heavy clay soils that stay waterlogged. For container growing, mix equal parts potting soil, coarse perlite, and aged compost.
