Soil & site
Rich hills with lots of running room — vines go 10 feet and more.
Seedling care
Direct sow when soil is thoroughly warm.
Growing notes
Plant at the garden's edge and let vines run outward. Butternut types resist vine borers — a smart pick in the South.
Harvest
When the rind resists a fingernail and the stem corks over. Cure 10 days somewhere warm; stores for months.
