✅ 1. Description
Common Names: Cashew, Grafted Cashew Nut
Scientific Name: Anacardium occidentale
Overview:
Grafted cashew trees are propagated through grafting techniques to ensure early fruiting, uniform quality, and high yield. They are preferred over seed-grown trees due to their faster and more reliable production.
Fruit Description:
- Cashew nuts grow at the end of the cashew apple (a fleshy, juicy part)
- The apple is edible (used for juices), and the nut is processed after harvest
- Nut has a kidney shape and is enclosed in a hard shell with toxic resin (needs proper processing)

🌼 6. Caring Tips
☀️ Sunlight:
- Needs full sunlight (minimum 6–8 hours/day)
💧 Watering:
- Young plants: Regular watering during the first year
- Mature trees: Drought-resistant; water during flowering and fruiting season
🌱 Soil:
- Ensure well-drained soil
- Avoid heavy clay or waterlogged soils
🌿 Fertilizer:
- Apply organic compost during monsoon
- NPK 15:15:15 or cashew-specific mix can be applied twice a year
✂️ Pruning:
- Light pruning after harvest to shape tree and improve air circulation
- Remove dead/diseased branches regularly
🐛 Pest Control:
- Watch for tea mosquito bug, stem borers
- Use neem oil or mild pesticides
- Apply Bordeaux mixture as preventive spray
