Growing Notes
Direct sow after last frost, or start indoors 2–3 weeks early. Chirimen thrives in full sun with consistent moisture. As a Cucurbita moschata, it is highly resistant to squash vine borers and handles summer heat well. Harvest when skin hardens fully and stem begins to dry. Cure in a sunny spot for 10 days before storage.
