How to grow

Direct sow 1 inch deep in warm soil after all danger of frost, in hills with room for the vines to run. Grow in full sun in rich, well-drained soil and water deeply and consistently, reducing water as the fruit ripens to boost sweetness. Harvest when the ground spot turns creamy yellow and the curly tendril near the fruit dries.
