Harvest and Storage
Butternuts should be ready to harvest after 75-150 days. They should mature on the plant. If you harvest too early, the quality will not be as good. The skin should be tough and not scratch easily.
Harvest the fruit with a part of the stem attached. Take care not to damage the fruit during harvest. It will store for longer.
Store butternuts in a cool dry place until the market price is good. Store for up to 4 months.
