Grow Cucurbita moschata 'Honeynut' for rich, sweet, single-serve butternut-type squash on long, vigorous vines. You will get the best flavor when the plant has steady warmth, sun, and consistent moisture through summer, followed by time to finish ripening before frost.
Plant after danger of frost has passed and the soil is warm. Choose a sheltered spot in full sun with fertile, well-drained soil. Work in compost, then sow seeds or set sturdy transplants with ample spacing so vines can trail or climb. If you train the vine on a trellis, support developing fruit with slings.
Water deeply at the base to keep soil evenly moist, then mulch to reduce swings in soil moisture and temperature. Avoid wetting foliage when possible. As flowers open, pollinators usually handle the job, but in poor weather you can hand-pollinate by moving pollen from a male bloom to the center of a female bloom with the small swelling at its base.
Harvest when rinds are firm and color is fully developed. Cut fruit with a short stem attached, handle gently to prevent bruising, and cure in a warm, dry place to help the skin harden. Store in a cool, dry location and check occasionally for soft spots.
