How to Store Swiss Chard
Swiss chard is more sturdy than spinach but still wants cold, moist storage. Cool it quickly after harvest for best keeping quality.
Best storage conditions
Store at 32 to 36 F with high humidity, around 95 percent. Keep it dark in the refrigerator.
How long it keeps
Usually 7 to 14 days, depending on leaf maturity and handling.
Storage methods
Leave leaves unwashed until use, or wash and dry thoroughly before storing. Place in a perforated bag or lidded container with a dry towel to manage moisture. Do not let leaves sit crushed or wet.
Freezing & preserving
Freeze after washing and blanching. Chard can also be dried for soup or seasoning uses. For canning, use tested USDA or NCHFP recipes, and because it is low-acid it requires pressure canning.
Tips
Use damaged outer leaves first. Keep away from ethylene-producing apples, pears, and melons.
