- Harvest potatoes when the leaves start to turn yellow. This is a sign that the crop is ready for harvest.
- Before harvesting, make sure the skin of tubers has hardened. To harden skin, let plant tops dry naturally or cut the top of plants 2 weeks before harvest. When the potato tuber skin is hard, it is not easy to damage at harvest.
- Do not leave mature potato tubers for more than 2 weeks in the soil after removing the tops. This will avoid attack by soil insects and rotting.
- Harvest in dry weather as this is good time for quicker drying of tubers and healing of skin wounds. Wet soil makes harvesting difficult and may lead to tubers getting diseases.
