When to Harvest Garlic (and How to Cure It Properly)

Not sure when to harvest garlic? Learn the right timing, how to harvest properly, and how to cure garlic so it stores for months.
Harvesting garlic at the right time makes a big difference in bulb size, storage life, and overall quality. Pull it too early and the bulbs haven't fully developed. Wait too long and the protective wrappers begin to break down. Getting the timing right, and curing it properly afterward, is what allows garlic to store well for months instead of weeks.
When Is Garlic Ready to Harvest?
Garlic is typically ready to harvest in early to mid-summer, depending on your climate and when it was planted. The most reliable indicator is the leaves.
As garlic matures, the lower leaves turn brown while the upper leaves remain green. The ideal time to harvest is when about half the leaves are still green and half have dried down. Each green leaf corresponds to a wrapper layer around the bulb. If too many leaves die back before harvest, those protective layers are gone. Fewer wrappers means cloves are more exposed, which reduces storage life significantly.
Don't Wait Too Long
It's common to think that leaving garlic in the ground longer will produce bigger bulbs. In reality, waiting too long usually has the opposite effect. If garlic is left in the ground past its window, the outer wrappers begin to break down, cloves can start to separate, and bulbs become more vulnerable to moisture and soil. Once the bulb starts to open or lose its wrapper layers, it won't store well.
It's generally better to harvest slightly early than too late.
How to Harvest Garlic
Use a garden fork or shovel to loosen the soil around each plant before removing it. Gently lift the bulbs out rather than pulling hard on the stems. Shake off excess dirt but don't wash them.
Avoid pulling garlic straight out of the ground by the stem. Pulling can break the stem away from the bulb, which creates an entry point for disease and reduces storage life. Don't wash freshly harvested garlic either. Washing introduces moisture that leads to mold and slows down the curing process.
Move garlic to a shaded area as soon as it's harvested. The outer layers are still soft at this stage and direct sun can cause sunburn on the bulbs. Leave stems and roots intact for now. Trimming them before curing removes protection that helps the bulb resist microbes while it dries.
What Is Curing and Why It Matters
Curing is the process of drying garlic after harvest so it stores properly. Fresh garlic is still full of moisture. Without proper curing, it will mold or rot rather than store long-term. During curing, moisture leaves the bulb, the outer layers dry into protective papery wrappers, and flavor develops and stabilizes.
Curing is what turns freshly harvested garlic into a stable, shelf-ready product that lasts months.
How to Cure Garlic
Hang bulbs in bunches or lay them out on racks in a dry, well-ventilated space out of direct sunlight. Airflow is the most important factor. Good circulation removes moisture evenly and prevents the pockets of humidity that cause mold. Shade matters too. Direct sunlight can dry the outside too quickly while trapping moisture inside.
Curing typically takes 3 to 4 weeks. You'll know it's done when the skins are dry and papery, the roots are dry, and the stems have dried completely through.
A covered porch, barn, garage, or shed with open doors works well. If you're using a barn, leaving doors open improves ventilation. Air movement matters more than temperature in most cases.
After Curing
Once garlic is fully cured, trim the roots close to the base and cut the stem down to about an inch. Brush off any remaining dirt. Store in a cool, dry place with good airflow. Mesh bags, wire baskets, or open crates all work. Avoid sealed containers or plastic bags. Garlic needs to breathe, and trapped moisture shortens shelf life quickly.
Most hardnecks store 4 to 6 months properly cured. Softnecks and Donostia Red can go longer. If you're planning your next season, start with quality seed garlic and it'll take you from this step all the way back around.
