Garlic scapes are the curly, tender flower stalks produced by hardneck garlic (Allium sativum) in late spring. By harvesting these, you not only gain a flavorful ingredient but also redirect the plant's energy toward bulb development. You will learn how to identify the right moment to harvest and how to best utilize this savory spring treat in your kitchen.
Identifying the Scape
As temperatures rise in late May or June, hardneck garlic varieties begin to send up a central stalk that eventually curls into a loop. This is the scape. It is important to harvest these stalks before the flower bud at the tip begins to swell or straighten out. If you wait too long, the plant begins to invest energy into seed production rather than enlarging the underground bulb.
Proper Harvesting Techniques
To harvest, simply snap or snip the scape off where it emerges from the top set of leaves. Use a clean pair of garden shears or your fingers to make a crisp cut. Snapping them is often easier as they naturally break at their most tender point. For gardeners in USDA zones 5 through 8, this task typically occurs a few weeks before the main garlic harvest.
Pro Tip: Don't compost your scapes! These vibrant green stalks have a mild, garlicky flavor that makes them perfect for pesto, stir-fries, or grilling with a light brush of olive oil.
Culinary Uses
Because scapes are younger and more tender than mature garlic cloves, they are incredibly versatile. You can chop them finely to use as a substitute for green onions or garlic in almost any dish. When sautéed in a pan at 350°F, they soften beautifully and lose much of their raw bite.
- Wash the scapes thoroughly under cool water.
- Trim off the pointed, woody tip if it feels tough.
- Chop the remaining stem into 1-inch pieces.
- Store them in a plastic bag in your refrigerator crisper for up to two weeks.
Benefits to the Bulb
By removing these stalks, you signal your garlic to stop reproduction efforts. Research shows that removing scapes consistently can result in significantly larger garlic bulbs by the time you harvest your main crop in mid-summer. It is a win-win situation for both your kitchen and your pantry.
