What is Allspice?
Allspice comes from the dried berries of the Pimenta dioica tree. The evergreen tree can grow up to 10–18 meters tall under ideal conditions. The berries are harvested when green and then dried to produce the familiar brown spice used worldwide.

- Germination time: 4–6 weeks
2. Grafting or Cuttings
- Faster fruiting
- Uniform plant growth
Land Preparation
- Deep plough the field
- Remove weeds and stones
- Mix organic manure (10–15 kg per pit)
- Prepare pits of 50 cm × 50 cm × 50 cm
Spacing:
