Growing directions
Sow seeds 1 inch deep in warm, compost-enriched hills, placing 3 seeds per hill and thinning to 1–2 plants. Give vines ample room to spread, or train onto a strong trellis and support heavy fruits with a sling. The rind turns from pale green to golden yellow when mature and will feel hard when pressed. Allow picked fruits to cure in a warm spot for 1–2 weeks before using or storing; they keep for several months in a cool, dry room.
