Cashew Tree Overview
Site Selection

- Soil: Choose well-drained sandy loam or sandy soils with a pH between 5.5 and 7.0. Avoid heavy clay soils.
Planting Location
- Climate: Given your location in Chennai, India, the tropical climate is ideal for cashew trees.
- Soil: Ensure your planting area has well-drained sandy or loamy soil with a pH between 5 and 6.5. Avoid waterlogged areas.
- Sunlight: Choose a spot with full sunlight for at least 6-8 hours daily.
Watering
- Young Trees: Water deeply once a week, especially during dry spells.
- Mature Trees: Water less frequently, focusing on dry periods and flowering/fruiting stages. Avoid over watering.
Fertilization
- Organic Fertilizers: Apply compost or well-rotted manure annually in spring.
- NPK Fertilizer: Use a balanced NPK fertilizer (e.g., 10-10-10 or 15-15-15) every 6-8 weeks during the growing season.
- Micronutrients: Consider foliar sprays or soil amendments for magnesium, zinc, and boron.
Pruning
- Initial Pruning: Shape the young tree by removing weak or crossing branches.
- Annual Maintenance: Prune dead or damaged branches after fruiting to promote health and production.
Pest and Disease Control
- Monitor for Pests: Keep an eye out for aphids, mealybugs, and leaf miners.
- Use Organic Controls: Neem oil or insecticidal soap can help manage pests.
- Prevent Diseases: Watch for fungal infections like powdery mildew and anthracnose. Copper-based fungicides may be necessary.
- Weed Control: Regularly weed around the tree to reduce competition for nutrients and water.
Mulching
- Apply Mulch: Use organic mulch (e.g., straw, leaves) around the base of the tree, leaving space around the trunk.
