Storing Swiss Chard
Preserving Swiss chard’s freshness optimizes its nutritional quality. Here are some storage tips:
– Rinse under cool water after harvest. Gently shake off excess water.

– Place unwashed leaves in a plastic bag or container. Squeeze out excess air and seal.
– Refrigerate unwashed leaves for up to 3-5 days. Wash just before use.

– Wrapping stems in a damp paper towel and refrigerating in a container can extend storage life.
– Chopped, cooked chard can be frozen for later use in soups, casseroles and other dishes.
Proper post-harvest handling keeps Swiss chard fresh and nutritious. Storing leaves dry and refrigerated is ideal for preserving quality.
