Why Garlic Belongs in Every Kitchen Garden
Garlic is planted in fall, overwintered without care, harvested in summer, and stores for 6-12 months. It requires no pest management, produces scapes (a bonus edible) in spring, and the flavor difference between homegrown and store-bought is dramatic. It is one of the highest value-to-effort crops in any kitchen garden.
When to Plant
Garlic goes in fall — 4-6 weeks before the ground freezes, after the first frost has cooled soil but before hard freeze. Timing by zone: zone 3-4: late September to mid-October; zone 5-6: October to early November; zone 7-8: November; zone 9-10: November through January (requires hardneck varieties that can handle mild winters).
Variety Selection
Hardneck Varieties
More flavorful, produce edible scapes in spring, store 4-6 months. Better for zones 3-7. Subtypes: Rocambole (richest flavor, stores shortest), Purple Stripe (strong flavor, good storage), Porcelain (large cloves, 6 months storage), Glazed Purple Stripe. Hardneck garlic is what you want for cooking quality.
Softneck Varieties
Milder flavor, no scapes, store 9-12 months. What grocery stores sell. Better for zones 7-10 where mild winters do not provide the cold hardneck varieties prefer. Artichoke and Silverskin are the most common subtypes.
Planting in Raised Beds
Break bulbs into individual cloves. Plant each clove 2 inches deep, 6 inches apart, pointed end up. Garlic spacing in raised beds: rows 6-8 inches apart, cloves 6 inches within rows. A 4x4 raised bed holds approximately 36 cloves. Mulch with 3-4 inches of straw after planting to protect from temperature swings.
Spring and Summer Care
Green shoots emerge in early spring. Remove scapes (the curling flower stalks) when they curl once — this directs energy to bulb development and the scapes are delicious sauteed or in pesto. Water consistently through spring; reduce water in June as bulbs mature. Do not fertilize after the scapes form.
Harvesting and Curing
Harvest when lower leaves have browned (typically 2-3 brown) but upper leaves are still green — usually June in zones 5-6, July in zones 3-4. Pull gently, brush off soil (do not wash), and cure in a warm, dry, ventilated location for 3-4 weeks. After curing, trim roots and stems and store in a cool, dry, dark location.
Frequently Asked Questions
Can I plant garlic from the grocery store?
Yes, but with caveats. Grocery store garlic may be treated with sprout inhibitors that reduce germination. Imported garlic may carry diseases not present in your region. Buying seed garlic from a local or regional grower is much more reliable and gives you variety options beyond generic white softneck.
How many garlic plants per person?
For a household that cooks with garlic regularly, plan 25-30 plants per person for year-round supply. This provides approximately 1-2 heads per week after curing loss. Scale down if garlic is occasional rather than daily. Growing 50 plants for two people produces enough for personal use plus gifting.
Why did my garlic produce small bulbs?
Most common causes: planted too close together (needs 6 inches minimum), harvested too early before bulb fully developed, insufficient fertility in the bed, or extremely dry spring. Garlic needs consistent moisture during spring growth and adequate nitrogen from composted soil to produce large bulbs.
Can I save my own seed garlic?
Yes — garlic is propagated vegetatively. Set aside the largest, healthiest heads from this year harvest as planting stock for next fall. Saving your own seed garlic year over year gradually selects for varieties adapted to your specific soil and climate. Do not save from diseased or small bulbs.
What pests affect garlic?
Garlic is remarkably pest-resistant — a significant part of its appeal. Occasional issues: onion thrips (silvery streaking on leaves), leek moth in some regions, and white rot (a soilborne fungal disease that causes rotting — do not plant in affected soil for 15-20 years). Garlic companion planting is popular because of its natural pest-repelling properties.
