How to Grow Elephant Garlic in Your Garden

Elephant garlic produces oversized bulbs with a milder flavor than true garlic. It is actually a type of leek, but its growing and harvesting routine is similar to garlic’s. Start with firm, healthy cloves and a spot that gets at least six hours of direct sun; in warm-winter regions, follow local planting guidance for the best season.

What You’ll Need

Firm elephant garlic bulbs or individual cloves for planting, preferably from a garden supplier rather than grocery-store bulbs, which may be treated or poorly suited to your climate.
A sunny garden bed or deep container with drainage holes.
Loose, fertile, well-drained soil, compost, and a trowel or hand fork.
Watering can or hose, mulch such as clean straw, and garden scissors for flower stalks.

Step-by-Step

Choose the site. Select a place with full sun and soil that drains after rain. Elephant garlic can grow in a large container, but bulbs need room: choose one at least 12 inches deep and provide drainage. Avoid low spots where water collects, since soggy soil can rot cloves.
Prepare the soil. Loosen the bed 8 to 10 inches deep and remove weeds and stones. Mix in finished compost to improve soil structure and fertility. If you know your soil is very acidic or alkaline, use a soil test and adjust according to its recommendations rather than adding amendments by guesswork.
Separate the cloves. Break the bulb into individual cloves shortly before planting. Keep the papery skin intact and discard cloves that are soft, moldy, or damaged. The largest sound cloves generally make the strongest plants. A small outer corm, if present, can also be planted, but it may take more than one season to form a full-size bulb.
Plant at the right depth. In fall, plant each clove with its pointed end up, about 4 to 6 inches deep. Space cloves 8 to 12 inches apart, with rows about 18 to 24 inches apart. Cover with soil and water gently to settle it. Plant early enough for roots to develop before the ground freezes, but not so early that warm weather encourages excessive top growth.
Mulch after planting. Spread 2 to 4 inches of loose straw or leaf mulch over the bed after the soil cools. Mulch moderates temperature, conserves moisture, and suppresses weeds. In a wet climate, use a lighter layer so the bed does not stay waterlogged; pull mulch back if it mats heavily against emerging shoots in spring.
Water and weed through spring. Keep the soil evenly moist while plants are actively growing, especially during dry spells and as bulbs begin to swell. Water deeply enough to reach the root zone, then allow excess water to drain. Reduce watering as foliage yellows near harvest. Remove weeds early by hand or with shallow cultivation; deep hoeing can damage shallow roots and developing bulbs.
Decide what to do with flower stalks. Some plants produce a tall, curling stalk called a scape. Cut it near the top leaves once it curls, if your priority is bulb growth. Leaving it will not ruin the plant, but removing it directs more energy toward the bulb. The tender stalk can be used in cooking.
Harvest when the leaves signal readiness. In many gardens, bulbs are ready in late spring or summer, but timing varies with climate and planting date. When several lower leaves have turned brown while the upper leaves remain green, loosen the soil with a fork a few inches away from the plant and lift the bulb gently. Do not pull hard on the stem, which can break it or bruise the bulb.
Cure and store the bulbs. Brush off loose soil without washing, then cure bulbs in a dry, shaded, airy place for about two to four weeks. Keep them out of direct sun and rain. When the outer skins are papery and the neck is dry, trim roots and stems or braid suitable tops. Store unpeeled bulbs in a cool, dry, well-ventilated place; check regularly and use any soft or damaged bulbs first.

Common Mistakes

Planting too shallowly can leave cloves exposed to frost or drying, while crowding limits bulb size and airflow. Use the stated depth and spacing rather than treating elephant garlic as miniature garlic. Heavy, persistently wet soil is another common problem; improve drainage or use a raised bed instead of watering on a fixed schedule.

Do not harvest as soon as one leaf yellows. Wait until several lower leaves have browned, but lift the bulbs before the whole plant collapses and the protective wrappers break down. Also avoid washing bulbs before curing: moisture trapped around the neck encourages spoilage.

Tips

Rotate the planting area and avoid following other alliums, such as onions, leeks, or garlic, in the same bed when possible. This reduces the chance of carrying over pests and diseases. Keep a simple note of planting and harvest dates so you can adjust timing to your local conditions next season.

For larger bulbs, prioritize sun, steady moisture during active growth, weed control, and adequate spacing. A balanced approach to soil fertility is better than applying lots of nitrogen late in the season, which can favor leafy growth over mature bulbs. Save only the healthiest, largest cloves for replanting, and do not rely on every harvested bulb to store equally well.

Troubleshooting

Cloves fail to sprout: They may have rotted in wet soil, dried out, or been planted too late. Check drainage and clove firmness before planting, and replant sound cloves in a better-drained spot during the appropriate local planting window.

Plants have yellow leaves early: Check whether the bed is waterlogged or very dry, and look for damaged roots or signs of pests. A few older leaves naturally yellow as bulbs mature; widespread early yellowing is not a harvest signal by itself.

Bulbs stay small: Common causes include shade, crowded planting, weeds, drought during bulb growth, or harvesting too soon. Improve sun and spacing, keep moisture even in spring, and wait for several lower leaves to brown before lifting.

Bulbs rot or develop mold in storage: The crop may have been harvested wet, bruised, or cured in a humid, poorly ventilated place. Remove affected bulbs, cure the rest in a drier airy location, and store only firm bulbs with intact skins.

Frequently Asked Questions

Is elephant garlic real garlic?

No. It is a large-growing relative of leek, not a true garlic species, though it forms garlic-like bulbs and is grown in a similar way.

When should I plant elephant garlic?

Fall is the usual choice in regions with cold winters: plant before the ground freezes so cloves can establish roots. In mild-winter areas, local growing guidance can help determine the best planting season.

Can I grow elephant garlic in a pot?

Yes, if the container is deep, has drainage holes, and is wide enough to maintain 8 to 12 inches between plants. Use loose potting mix and monitor moisture more often than you would in a garden bed.

How long does elephant garlic take to grow?

It usually grows from fall planting to a late-spring or summer harvest, depending on climate and conditions. Use leaf color, not a fixed number of days, to judge when bulbs are ready.

Can I eat the scapes?

Yes. Cut young, tender scapes when they curl and use them like a mild allium in cooking. Removing them can help the plant put more energy into its bulb.

How should I save cloves for next year?

Cure the bulbs fully, then keep firm, intact bulbs in a cool, dry, well-ventilated place. Replant the largest healthy cloves in fall; do not plant cloves that are soft or moldy.
