🌱 How to Care for Capirona to Prevent Leaf Spot?

💧 How to Water

In the first 2-3 years after planting, water regularly every 7 days, keeping the soil evenly moist but not waterlogged. Mature trees are moderately drought-tolerant and can thrive on seasonal rainfall alone, but benefit from supplemental watering during prolonged dry spells.

☀️ Lighting

Requires full sun for healthy development, with at least 6-8 hours of direct sunlight per day. In shaded locations, growth is significantly reduced and the tree loses its most distinctive characteristics.

🪴 Ideal Soil

Plant in fertile, deep, well-draining soil rich in organic matter. Ideal pH is between 6.0 and 7.5. Avoid compacted soils or areas with poor drainage, as waterlogged roots can compromise seedling development.
