How to Harvest Collard Greens?

Harvesting collard greens is a simple process that can be done by hand. Before harvest:

The bag should remain closed until you are ready to prepare and eat the collard greens.

For longer storage times, your best option is to freeze them. Start by cutting the leaves off their stems, then blanching them in boiling water for 3 minutes before draining. This process helps preserve color, flavor, and nutrients. Place the blanched collard greens into a freezer-safe bag or container, and store them in the freezer for up to 6 months.

If you don’t have access to a freezer, you can also preserve collard greens by canning them. Start by cutting off the stems of the leaves and blanching as described above.
