Prof. Samuel Fitzgerald, Ph.D.Post-harvest handling is integral to squash quality and shelf life. Summer squash needs to be cooled right away, whereas winter squash needs to be cured. These crops are susceptible to rapid spoilage and loss of flavor when mishandled. I once ruined a harvest because I washed the winter squash before curing them.
Field Processing
- Gently wipe: Remove dirt with soft cloth without water
- Stem check: Ensure 1-inch stem on summer, 3-inch on winter
- Damage sort: Separate bruised squash for immediate use
Temperature Management
- Summer: Get to 45-50°F refrigerator within 2 hours
- Winter: Move to 80-85°F curing area immediately
- Monitoring: Use thermometer in storage areas
Long-Term Storage
- Summer: Store in perforated bags at 85-90% humidity
- Winter: After curing, keep at 50-55°F with 50-70% humidity
- Airflow: Use slatted shelves, never airtight containers
Curing winter squash enhances both its taste and texture consistency. It's simply a matter of placing the squash in a warm environment of 80-85°F with good air circulation for 10-14 days. During the curing process, starch is converted to sugars, and the skin hardens. Note that acorn squash should never be cured, as it will turn stringy and nasty.
Refrigeration practices on summer squash eliminate moisture loss. Use perforated plastic bags in the crisper drawer. Keep humidity at 85-90% to prevent shriveling. I always add a damp paper towel to bags to prevent drying out during dry winters.
Managing Ethylene is very important. Keep squash away from apples, tomatoes, and bananas, as these fruits and vegetables all emit gases that accelerate decay. Store summer squash separately from other types of produce. I even set aside dedicated drawers in my refrigerator just for squash.
Follow these methods for maximum freshness. Your summer squash will last 10 days, while winter varieties store for months. I now enjoy garden squash through winter thanks to proper handling.
