Storage & Preservation
Fresh Grand Rapids lettuce keeps best when harvested in the morning and immediately placed in cold water to crisp up. Gently pat leaves dry and store in perforated plastic bags in your refrigerator's crisper drawer at 32-36°F with high humidity. Properly stored leaves stay fresh for 7-10 days.
For preservation, freezing isn't recommended as lettuce becomes mushy when thawed. Instead, dehydrate leaves at 95°F for 6-8 hours to create crispy lettuce chips for soups and seasoning. You can also preserve the harvest by succession planting – since Grand Rapids handles heat well, plant new crops every 2-3 weeks for fresh lettuce year-round. In mild winter areas, this variety overwinters well under row covers, providing fresh greens when other vegetables are dormant.
