- Cultivation is almost invariably restricted to Tropical areas.
2. Rainfall:
- Needs high rainfall and should be well distributed (100-200 cm)

3. Shade:
- Should be sheltered from direct sun light especially when young.
- Tall leguminous plants are sometimes used.
4. Uplands conditions:
- Well drained, cool conditions.
- Best quality comes from high elevation and slopes.
- 2000-6000 ft.
- Slopes which face sea benefit from sea mist
5. Soils:
- Yield dependent on soil nutrients, decline sharply when soil is exhausted.
- Well drained volcanic soil like Terra roxa of Brazil which contain much potash as well as organic material.
6. Labour:
- Handpicked therefore no machine.
- Every stage requires.
