Plant Garlic This Fall for Summer Harvest

Why Plant Garlic in Fall?

Garlic planted in October develops strong root systems before winter, giving it a head start when spring arrives. Fall-planted garlic consistently produces bulbs 30 to 50 percent larger than spring-planted cloves. The cold period is essential for proper bulb formation in hardneck varieties.

Choosing the Right Garlic Variety

Hardneck Garlic

Best for cold climates. Produces a woody central stalk and large, easy-to-peel cloves. Popular varieties include Rocambole, Purple Stripe, and Porcelain. Superior flavor but shorter storage life of four to six months.

Softneck Garlic

Better for mild climates. More cloves per bulb, longer storage life of eight to twelve months, and braidable stalks. Popular varieties include Silverskin and Artichoke. Less cold-hardy but more productive.

Soil Preparation

Garlic thrives in well-drained, fertile soil with a pH of 6.0 to 7.0. Two weeks before planting:

• Work two to three inches of compost into the top six inches of soil
• Add balanced organic fertilizer at five lbs per 100 sq ft
• Ensure the bed is loose and free of clumps for easy root penetration

How to Plant Garlic

Timing

Plant four to six weeks before the ground freezes. In most US zones, this means mid-October to early November. The cloves should root but not send up green shoots before winter.

Planting Method

1. Break the bulb into individual cloves and keep the papery skin on
2. Plant pointy-end up, two inches deep
3. Space cloves four to six inches apart in rows twelve inches apart
4. Water well after planting

Mulching

After planting, apply four to six inches of straw or shredded leaves. This insulates the soil, prevents frost heaving, and suppresses winter weeds. Pull mulch aside slightly in spring when green shoots emerge.

Spring and Summer Care

In spring, remove excess mulch once shoots are two inches tall. Hardneck garlic produces scapes in early summer. Cut them off to redirect energy to bulb growth. Water consistently until bulbs begin to mature in late June, then stop watering to allow bulbs to cure.

Harvesting and Curing

Harvest when the bottom three to four leaves turn brown but the top five to six leaves are still green. Gently lift bulbs with a garden fork.

Cure in a warm, dry, shaded location with good airflow for two to four weeks. After curing, trim roots to a quarter inch and stalks to one inch. Store in a cool, dry, dark place.

One planted clove produces one entire bulb, a 10x to 20x return on your investment. A single pound of seed garlic yields five to eight pounds at harvest.
