Vegetable Crop Calendars (A–C)Garlic Planting Calendar: Fall vs. Spring
Garlic wants a cold stretch to size up, so the best calendar usually begins in fall, with spring planting as a fallback.
Key points
- Fall planting gives garlic the cold it needs.
- Plant when roots can form before the ground freezes.
- Spring planting is a fallback with smaller bulbs.
- Buy seed garlic, not grocery bulbs.
- Cure bulbs in a shaded, airy place.
Why is fall the usual time to plant garlic?
Garlic cloves planted in fall make roots before the ground freezes, spend winter in the cold and start growth in spring. That cold exposure helps cloves split into well-formed bulbs. Extension guides in many states recommend fall planting for this reason.
The usual guidance is to plant late enough that tops do not grow tall before winter, but early enough that roots form. Your state guide gives the timing for your area.
If you are new to garlic, try two or three varieties in small amounts. Over a few seasons you will learn which ones size up, store well and suit your taste. Where winters are mild, garlic planted in fall may sprout and grow green tops through the winter, which is normal. Where winters are severe, mulch and snow cover protect cloves, and sprouts that appear in spring grow quickly once the soil warms.
How do you time a fall planting?
Use soil temperature and frost as your guides. Plant when the soil has cooled after summer but weeks before the ground freezes solid, so roots establish. Many guides tie the timing to a window around the first fall frost, and the window differs by region.
For example, in an area where the ground freezes in early winter, you might plant a few weeks after the first frost. This is an example only. Check your state publication for your region's timing.
Mulch planted beds to protect against freeze and thaw cycles that push cloves up. Separate cloves from the bulb shortly before planting and keep the papery skin on. Plant the largest cloves, since they tend to produce larger bulbs.
- Find your average first fall frost date.
- Check your state guide for the planting window.
- Plant cloves root end down at the guide's depth.
- Mulch after planting.
Can you plant garlic in spring?
Yes, in some places, and it is a reasonable fallback. Spring-planted garlic goes in as early as the soil can be worked, because it needs cool weather to grow before summer heat. Bulbs from spring planting are often smaller than those planted in fall.
Some varieties perform better than others in spring plantings. Ask your extension office or local growers which ones work in your area.
Another approach is to chill cloves before spring planting, and some guides describe this. Check your state guide for details. Soil should be loose and well drained, since standing water over winter rots cloves. A raised bed helps where drainage is poor. If you only have a spring bed available, treat the crop as an experiment and expect smaller bulbs. Green garlic, which is harvested young as a spring crop, is another way to use spring plantings if bulbs do not size up.
Which type of garlic suits your climate?
Hardneck types tend to perform well in cold climates and send up a flower stalk called a scape. Softneck types often suit milder winters and store longer. Variety choice affects timing, storage and flavor.
Use planting stock sold for seed purposes, rather than grocery store bulbs, since those may carry disease or may not be adapted to your area.
Local garlic growers and farmers market vendors know which varieties thrive near you, and many sell seed garlic in late summer, so ask before they sell out.
How do you care for the crop?
Garlic likes fertile, well-drained soil and steady moisture in spring. A soil test shows what the bed needs, and your extension office can interpret it. Nutrient management rules vary by state, so follow local recommendations.
Keep beds weeded, because garlic competes poorly. Reduce watering as tops begin to yellow near harvest.
Scapes from hardneck types can be snipped off in late spring, and many guides suggest this to direct energy to the bulb. Scapes are also edible.
When is harvest and how do you cure it?
Harvest when lower leaves turn brown but several green leaves remain, which many guides use as a sign. Dig gently and cure bulbs in a shaded, airy place. Check your state guide for timing, since it depends on climate and variety.
For preserving garlic in oil, pickling or other methods, use only tested procedures from the National Center for Home Food Preservation. Garlic in oil carries food safety risks if handled wrongly.
Store cured bulbs in a cool, dry, airy place away from direct light, and save your best bulbs as seed stock for the next fall planting.
