Soil, care & harvest

Prepare loose, well-draining soil with a pH between 6.0 and 7.0. As a warm-season crop, you must wait until after the last spring frost when the ground is fully warm before sowing directly outdoors. Do not start indoors; these seeds are best planted in the garden bed once frost danger has passed completely.

Space plants 48 to 72 inches apart to allow vines to spread freely, as trellising is generally unnecessary for this sprawling variety. Provide 1 to 2 inches of water weekly with deep soakings, and apply mulch around the base to retain moisture. Feed regularly if soil nutrients are low to support vigorous vine growth.

Watch for cucumber beetles, squash bugs, aphids, and spider mites; use row covers or insecticidal soap early in the season. Prevent fungal diseases like powdery mildew by ensuring good air circulation and avoiding overhead watering. Harvest fruit 90 to 100 days after sowing when the rind hardens and loses its sheen.
