Swiss chard tends to have a very long harvest period.  When the outside leaves are at least 6" long, harvest as needed by picking (only) the outside leaves. Do not cut the stalks, but break or peel off in a downwards motion. 

Leave the younger stalks alone, so the plant continues to grow (it will produce this way for you all season).  Or, you can cut the whole plant to 2” tall, and let the enitire swiss chard plant grow again.

Canning Swiss Chard (and other greens) (back to top)
NOTE: This is only a guideline. If not canned properly very dangerous (life-threatening) bacteria can grow undetected in your jars. Be sure to follow standard sanitation and canning procedures, as outlined in your canning cookbook or by your local county extension office. Also, follow your specific canner's manufacturer's instructions.

Note: processing time given is for at sea level. If you're above sea level, the cooking time will be longer. Again, check with your local county extension office for conversion rates for your area, to ensure that you're producing a safe canned food product. Your local county extension office may also be able to test your pressure cooker's gauge for accuracy.

Wash swiss chard thoroughly several times. Trim away the tough stems. Steam the greens until wilted. (You can turn the greens over while steaming to prevent overcooking.) Chop the wilted swiss chard leaves coarsely.

Pack hot greens into hot jars. Leave 1" space at the top of the jar. Add 1/2 tsp salt per pint (1 tsp salt per quart jar). Cover with boling water and fill, but leave the 1" of space at the top. Use a rubber spatula to remove air bubbles. Wipe the top of the jar and the threads with a clean damp cloth. Add sterilized caps. Process at 10lbs pressure in pressure canner for 1 hour 10 min (pints) or 1 hour 30 min (quarts). Store jars in dark cabinets or pantries to prevent discoloration.

NOTE: Be sure to follow your pressure cooker's manufacturer supplied instructions for safety.

Follow your canning cookbook's instructions for removing, cooling and storing the jars.
