Garlic (Allium sativum) rewards minimal effort with maximum flavor—and health benefits. Success hinges on variety selection, timing, and soil preparation.

Types & Varieties

Type	Characteristics	Varieties	Best For
Hardneck	Stiff central scape; complex flavors; fewer, larger cloves; cold-hardy	'Music', 'German Extra Hardy', 'Chesnok Red', 'Purple Stripe'	Northern climates; scape harvest
Softneck	No scape; more cloves/head; braidable; longer storage; milder	'Inchelium Red', 'California Early', 'Silverskin', 'Artichoke'	Mild winters; long storage; braiding

Critical: Source Local Seed Garlic

• Supermarket garlic = treated against sprouting, wrong variety for your zone.
• Buy from local growers, farmers markets, or regional seed companies.
• Varieties adapt to specific day-length/temperature profiles.

Soil & Site Preparation

• Sun: Full (6+ hrs).
• Soil: Loose, fertile, well-drained, pH 6.0–7.0.
• Amend: 2–3″ compost + balanced fertilizer (5-10-10) 1 month before planting.
• Rotation: Avoid alliums (onions, leeks) for 3 years.

Planting Protocol

1. Timing: Fall (Sept–Nov north; Oct–Dec south). 4–6 weeks before ground freezes.
2. Clove prep: Separate heads day of planting. Use largest outer cloves.
3. Depth: 2″ (north) to 1″ (south) deep.
4. Spacing: 6″ apart, rows 12″ apart.
5. Orientation: Pointy end up, basal plate down.
6. Mulch: 4–6″ straw/leaves after freeze.

Growing & Harvest

• Spring: Remove mulch as shoots emerge. Fertilize (blood meal) at 6″ growth.
• Scapes (hardneck): Cut when curled—redirects energy to bulb. Eat scapes!
• Water: 1″/week until 2 weeks before harvest.
• Harvest signal: Bottom 3–4 leaves brown, top 50% green.
• Test: Dig one; cloves should fill skins tightly.
• Cure: 2–3 weeks shaded, airy. Trim roots/stems. Store 40–60°F, 60% humidity.

Storage Life

• Softneck: 8–12 months.
• Hardneck: 4–7 months.

Plant once, harvest for months. Garlic is the highest-ROI crop in any kitchen garden.
