Elephant garlic, a large, mild member of the Allium family, is botanically a type of leek (Allium ampeloprasum) rather than true garlic (Allium sativum). This botanical difference accounts for its milder flavor profile, which is generally sweeter and less pungent than conventional garlic. Properly harvesting and curing this crop is important for maximizing the flavor concentration and ensuring the longest possible storage life for the bulbs.
Recognizing Peak Harvest Time
Determining the precise moment for harvesting elephant garlic relies on observing the plant’s foliage, signaling that the underground bulb has finished its growth cycle. The correct time is indicated when the lower leaves begin to noticeably yellow and brown, a sign that the plant is redirecting energy to the bulb. Growers should aim to lift the bulbs when approximately one-third of the foliage has died back, but before the entire top of the plant is completely brown and collapsed.
The presence of a scape, or flower stalk, is a secondary indicator that bulbing is underway. Removing it is beneficial for the bulb’s development. Clipping the scape when it emerges redirects the plant’s energy, which would otherwise be spent on flowering and seed production, back into enlarging the underground bulb. Waiting too long to harvest is detrimental because the protective outer wrapper layers can begin to disintegrate in the soil, which reduces the bulb’s ability to store well.
Techniques for Lifting the Bulbs
The physical process of removing the large bulbs from the soil must be handled carefully to avoid damaging the protective paper wrappers. It is important to resist the urge to simply pull the stalk, as this action can snap the neck of the bulb, creating an entry point for pathogens and significantly shortening its storage life. Instead, use a spading fork or a garden trowel, inserting the tool several inches away from the base of the plant to avoid stabbing the bulb.
Gently loosen the soil in a wide circle around the plant, working the tool underneath the bulb’s base to lift it slowly and carefully. Once the bulb is out of the ground, immediately brush off any large clumps of excess dirt clinging to the roots and wrappers. It is critical not to wash the bulbs with water at this stage, as introducing moisture will hinder the curing process and increase the risk of rot. Bulbs that are accidentally bruised or nicked during the lifting process should be set aside for immediate use, as they will not store long-term.
The Curing Process
Curing is a necessary intermediate step that dries the outer wrappers and the neck of the bulb, preparing the elephant garlic for extended storage. This process strengthens the wrappers, sealing the bulb and concentrating the flavor. The ideal curing environment is a warm location, generally between 75–85°F, with low humidity and continuous, robust airflow. Good ventilation is important to prevent moisture buildup, which can lead to mold or fungal issues.
The bulbs should be laid out in a single layer on wire racks or hung in small bundles, keeping them out of direct sunlight. This drying period typically lasts between two and four weeks, though it can extend up to eight weeks depending on the ambient humidity and temperature. The curing is complete when the outer wrappers feel papery and dry, and the stalk right above the bulb has shriveled and is completely dry to the touch. Once fully cured, the brittle roots can be trimmed close to the bulb, and the stalk can be cut down to about one inch above the bulb.
Storing Elephant Garlic
After the bulbs are cured, they must be moved to a permanent storage location to maximize their shelf life. The long-term preservation of elephant garlic requires cool temperatures, ideally ranging between 45–55°F, and moderate humidity levels, preferably around 50–70%. A basement, pantry, or cellar that maintains a relatively steady, cool temperature and dry air is often suitable.
To ensure good airflow and prevent moisture accumulation, the cured bulbs can be placed into mesh bags, which allow air to circulate freely around each bulb. If the stalks were kept long, the bulbs can also be braided and hung, creating an attractive and practical storage solution. Elephant garlic has a shorter natural storage life than true garlic, typically lasting about four to six months under perfect conditions. To maintain the bulb’s integrity and flavor, the cloves should be kept whole within their papery wrappers until they are needed for cooking.
