🌱 How to Care for Barbados cherry to Prevent Anthracnose?

💧 How to Water

Water when the top inch of soil feels dry. Established plants tolerate brief dry periods but produce more fruit with regular irrigation, especially in the dry season. Always ensure water drains freely to prevent root rot.

☀️ Lighting

Full sun is essential — at least 6 to 8 hours of direct sunlight daily. Partial shade drastically reduces flowering and fruit set. Outdoors, choose the sunniest spot available.

🪴 Ideal Soil

Prefers well-draining sandy or loamy soil with added organic matter. Target pH between 5.5 and 6.5 (slightly acidic). Avoid heavy clay. Mix in compost or pine bark at planting time to improve aeration and nutrient availability.
