To store garlic scapes, bundle them together with a rubber band and store in an airtight bag in the refrigerator for up to 3 weeks.
Garlic scapes can also be chopped, placed in a freezer-safe bag and stored frozen for up to one year.
Garlic scapes can also be pickled and fermented to keep long periods of time.
If you plan on eating them within 1-2 days, make a bouquet of garlic scapes in a vase of fresh water. Leave on your counter at room temperature and change water daily.
