Harvest entire kale plants at 60 to 80 days after germination when they are full size and no longer growing larger. Gather the leaves of one kale plant upward and hold them in this position. Cut across the bottom of the plant, horizontally about 1 inch above ground level to harvest the entire plant for side dishes, main dishes, soups or stews. Place the plants in a container to transport them indoors for storage or use.
The best time of day to harvest kale (and all greens for that matter) is early in the morning. Here is how to prepare and preserve kale in small portions for your freezer. Begin by boiling a large pot of water on the stove. Prepare an ice bath in a large bowl and set it on the counter next to the pot on the stove. Set up a drying station for your kale with kitchen towels or paper towel next to the ice bath. Place a few ice cube trays next to the drying station.
