If you’re growing elephant garlic, knowing when to harvest it is the key to getting those massive, flavorful bulbs. The optimal harvesting time for elephant garlic is not when the bulbs are biggest underground, but when the plant gives you clear signals from above.
Unlike regular garlic, elephant garlic is actually a type of leek, but it’s grown and harvested much like its smaller cousin. Picking it at the right moment ensures the bulbs store well and have developed their full, mild garlic flavor. Harvest too early, and the cloves won’t have formed their papery wrappers. Harvest too late, and the bulbs may have split open in the ground, making them vulnerable to rot and reducing their storage life.
When Do You Harvest Elephant Garlic – Optimal Harvesting Time For
So, how do you pinpoint that perfect harvest window? You need to become a detective and watch for visual clues on the plant itself. The calendar gives a rough estimate, but the plant’s appearance tells you the exact truth.
The Primary Signs of Readiness
Elephant garlic sends up a tall, solid flower stalk called a scape. While some gardeners remove these to direct energy to the bulb, leaving it on provides the best harvest signal.
- Leaf Condition: Watch the lower leaves. When about 40-50% of the leaves (starting from the bottom) have turned yellow or brown and died back, harvest is near. The top leaves should still be partially green.
- Stalk and Flower Head: The scape will begin to soften and lose its upright rigidity. The papery sheath covering the flower head will start to dry and split. Often, the ornamental flower head itself will begin to dry and fade in color.
The Seasonal Timeline
In most temperate climates, elephant garlic is planted in the fall. Given this schedule, here’s a general timeline:
- Late Spring to Early Summer: This is when scapes typically appear. You might cut them for eating if you wish.
- Mid to Late Summer: This is the prime harvest window. For many regions, this falls between late June and early August. The exact timing depends heavily on your local spring weather.
A warm, dry spring accelerates growth, while a cool, wet spring delays maturity. Always trust the plant’s signs over the calendar date.
What Happens If You Harvest Too Early?
Early-harvested bulbs are a disappointment. The cloves will be poorly defined and lack the protective papery skins. They’ll be more like a leek than garlic, and they won’t store for more than a few weeks. The flavor can also be sharper and less developed.
What Happens If You Harvest Too Late?
If you wait to long, the bulbs can split apart underground. Once split, soil and moisture get inside, leading to mold and rot. The cloves may also start to push out of the ground and sprout again, using up the stored energy meant for your kitchen.
The Test Dig Method
Unsure if your garlic is ready? Perform a test dig. Gently loosen the soil around one or two plants and feel the bulb without pulling it completely.
- Is the bulb a good size with clear clove definition bulging at the sides?
- Is the outer wrapper papery and intact?
If yes, you can proceed with the main harvest. If it still feels soft and small, cover it back up and wait another week.
Step-by-Step Harvesting Instructions
Once your plants show the signs, follow these steps for a successful harvest.
Step 1: Choose Your Day
Pick a dry day when the soil is not wet or muddy. Wet soil clings to the bulbs and can increase the chance of fungal issues during curing.
Step 2: Loosen the Soil
Use a garden fork or spade to gently loosen the soil about 6-8 inches away from the plant’s base. Insert the tool and lever it back to lift the soil, breaking the roots’ grip.
Step 3: Lift the Plants
Grab the plant near its base and gently pull it up. Avoid yanking by the stalk, as it can break off. If the plant is stubborn, loosen the soil more with the fork.
Step 4: Handle with Care
Elephant garlic bruises easily. Handle the bulbs gently to avoid cuts or dents, which create entry points for decay. Don’t wash them with water; just brush off the big clumps of soil.
Curing and Storing Your Harvest
Harvesting is only half the job. Proper curing is essential for long-term storage.
How to Cure Elephant Garlic
- Prepare: Keep the stalks and roots attached. Brush off excess soil.
- Find the Right Spot: Lay the bulbs in a single layer on a rack, screen, or hang them in small bunches. They need a warm, dry, dark, and well-ventilated place. A garage, covered porch, or shed is ideal.
- Let Them Dry: Allow the bulbs to cure for 3 to 6 weeks. The outer skins will become papery, the roots will shrivel, and the neck (above the bulb) will tighten up.
How to Store After Curing
Once fully cured, trim the roots to about 1/2 inch and cut the stalks down to 1-2 inches, unless your planning to braid them.
- Store the bulbs in a cool, dark, and dry place with good air circulation. A mesh bag, woven basket, or cardboard box with holes works well.
- Ideal storage temperature is between 50-60°F (10-15°C). Avoid refrigerating, as cold temperatures can trigger sprouting.
- Properly cured and stored elephant garlic can last 8 to 10 months.
Common Harvesting Mistakes to Avoid
- Harvesting after a rain: Wet bulbs are much harder to cure properly.
- Cutting off the tops immediately: This removes the plants ability to continue drawing energy down into the bulb during the early curing stage.
- Storing in plastic bags: This traps moisture and guarantees mold will form. Always use breathable containers.
- Ignoring the signs: Relying soley on a calendar date is the most common error. Your plants know best.
FAQ: Your Elephant Garlic Harvest Questions
Can you harvest elephant garlic early for green garlic?
Yes, you can pull plants in late spring for “green garlic.” The entire plant is edible and has a mild, fresh flavor, but you won’t get a cured bulb.
How long does elephant garlic take to grow?
From a fall planting, elephant garlic takes roughly 8 to 9 months to reach full maturity for a summer harvest.
The leaves on my elephant garlic are still mostly green. Is it ready?
Probably not. Wait until at least the bottom 40% have yellowed and died back. The bulbs still have some sizing up to do while those top leaves are green.
What if my elephant garlic flowered?
It’s normal for them to flower. The key signal is the flower stalk softening and the flower head drying out. This indicates the plant is finishing its cycle.
Can I leave elephant garlic in the ground over winter?
It’s planted in fall to overwinter. But after maturity the following summer, you must harvest it. Leaving mature bulbs in wet ground over a second winter will cause them to rot.
Why are my harvested bulbs so small?
Small bulbs can result from inadequate watering during bulb formation (in spring), poor soil fertility, or perhaps harvesting a bit to early. They also tend to produce larger bulbs when they experience a good chill period in winter.
Getting the harvest timing right for elephant garlic is simple once you know what to look for. Forget the exact date and focus on those yellowing leaves and softening flower stalks. With careful digging and proper curing, you’ll be rewarded with a bounty of massive, mild bulbs that will flavor your cooking for many months to come. A little patience at the end of the growing season makes all the difference.
