If spinach is slightly wilted when packed, it will be less subject to breakage. Usually, spinach is washed, repacked, and iced at a central packing shed if it is to be shipped. If this spinach is to be pre-packaged, the crowns are cut off during the packaging operation. Yields - Good yields of fresh market spinach are from 7,000 to 15,000 lb per acre or 280 to 600 bushel baskets or bushel crates per acre containing 20 to 25 lb each.
