🌱 How to Care for Jaboticaba to Prevent Grey Mould?

💧 How to Water

Keep soil consistently moist during spring and summer, but never waterlogged. Jaboticaba has poor drought tolerance; dry periods cause leaf tip burn and leaf drop. Use slightly acidic or neutral water. In winter, reduce watering and allow the soil surface to dry before watering again. Drip irrigation or bubbler systems are ideal for mature trees to maintain even moisture.

☀️ Lighting

Jaboticaba requires warmth and abundant sunlight for flowering and fruiting. Plant in full sun or mostly sunny locations. In very hot climates (above 95°F/35°C), provide partial shade during peak afternoon hours to prevent leaf scorch. Indoor specimens need bright light from a south-facing window or supplemental grow lights to thrive.

🪴 Ideal Soil

Soil must be well-draining, rich in organic matter, deep, and slightly acidic (pH 5.5–6.5, tolerating 4.5–8). Avoid heavy, compacted, or alkaline clay soils; in regions with alkaline soils, apply soil amendments to lower pH. A mixture similar to azalea soil (such as Kanuma) is ideal. Excellent drainage is essential to prevent root rot, as jaboticaba is sensitive to waterlogging.
