How to Grow Garlic from a Bulb

Plant individual garlic cloves pointed end up in fall, about 6 weeks before your first hard frost. Space them 4-6 inches apart in well-draining soil with the tip just below the surface. Garlic needs a cold winter to form bulbs properly, so patience is key — you'll harvest next summer when the bottom leaves turn brown.

Total time: 8-9 months
Hands-on: 2 hr
Difficulty: Easy

Ingredients

4 inches straw or leaves
12-16 weeks cold period below 45°F

Step by step

Choose your garlic type and timing. Buy seed garlic from a garden center, not grocery store bulbs which are often treated to prevent sprouting. Hardneck varieties work best in cold climates, softneck in warmer areas. Plant in fall — aim for 6 weeks before your area's first hard frost.
Prepare the planting site. Pick a sunny spot with loose, well-draining soil. Work compost into the bed if your soil is heavy clay. Garlic hates wet feet, so avoid low spots where water collects. Raised beds work perfectly.
Separate and plant the cloves. Break apart bulbs just before planting — don't do this days ahead or cloves dry out. Plant each clove pointed end up, about 2 inches deep with the tip just under soil level. Space them 4-6 inches apart in rows 12 inches apart.
Mulch and wait through winter. Cover the bed with 4 inches of straw or leaves after planting. This keeps weeds down and protects cloves through freezing weather. The cold period is essential — garlic needs 12-16 weeks below 45°F to form proper bulbs.
Tend the spring growth. Green shoots emerge when soil warms. Pull back mulch so shoots can grow freely. Water regularly if spring is dry — garlic needs consistent moisture while growing but not soggy soil.
Remove flower stalks. Hardneck varieties send up curly flower stalks called scapes in late spring. Cut these off when they make one full curl — this directs energy into bulb growth instead of flowers. The scapes are edible and taste like mild garlic.
Harvest at the right time. Stop watering when bottom leaves start turning brown but top leaves stay green — usually mid to late summer. Dig carefully with a fork, brush off soil, and let bulbs cure in a dry, ventilated place for 2-3 weeks.

Tips & troubleshooting

Save your biggest, best bulbs for replanting next year — garlic adapts to your local conditions over time
Don't plant grocery store garlic unless you only want greens — it rarely forms good bulbs
Mark your planting spots because garlic takes months to emerge and you'll forget where you planted
Braiding softneck garlic right after harvest keeps it fresh longer than storing loose bulbs

Variations

Container Growing. Use containers at least 8 inches deep with drainage holes. Plant cloves 2 inches apart. Move containers to an unheated garage or shed in zones warmer than 7 to provide the cold period garlic needs.
Spring Planting. In mild climates where soil doesn't freeze, you can plant in early spring. Chill bulbs in the refrigerator for 12 weeks before planting to simulate winter. Results may be smaller bulbs but still usable.
Garlic Greens Only. Plant cloves closer together and harvest the green tops when 6-8 inches tall. Use like scallions. This works even with grocery store garlic and doesn't require the cold treatment.

Questions

Why didn't my garlic form bulbs?: Garlic needs 12-16 weeks of cold weather below 45°F to trigger bulb formation. If you planted too late, had a warm winter, or used grocery store garlic, the plants may only produce greens without dividing into cloves.
Can I plant garlic cloves that have already started sprouting?: Yes, sprouted cloves often grow better because they're already active. Plant them the same way with the green shoot pointing up. Just handle them gently so you don't break off the sprout.
How long does garlic take to grow?: About 8-9 months from fall planting to summer harvest. The cloves need to go through winter dormancy, then grow actively in spring and early summer before forming mature bulbs.
What's the difference between hardneck and softneck garlic?: Hardneck varieties grow a central stalk with a flower head and need cold winters. They work best in northern climates. Softneck types don't flower, store longer, and tolerate warmer weather better.
