Harvest Tips
Pummelos mature 3-4 years after planting. Fruit ripens November-March in tropical regions. Harvest when skin fully yellows or pinks and fruit yields slightly to pressure. Use pruning shears to avoid damaging the tree. Fruits can hang on tree 2-3 weeks after ripening and store 2-3 months at room temperature.
Fun Facts
- 🌱 Pummelo is believed to be one of the original citrus species; all sweet oranges and grapefruits are hybrids descended partly from the pummelo.
- 🌱 The name 'pummelo' comes from Dutch traders in Southeast Asia; it's also called 'pomelo' or 'pommella' in different regions.
- 🌱 A single pummelo fruit can weigh 2-4 pounds and have a rind up to 1 inch thick—thicker than any other citrus—making it an excellent keeper that can last months without refrigeration.
