Plant garlic in fall, straight into a garden bed.

1. Work back from your local winter

Fall garlic planting is a next-season crop, not a quick autumn harvest. Reserve the bed until the following late spring or summer, depending on your variety and climate. A date suitable for northern New York may be too early elsewhere.

• Cold winter: ask your local Extension office or seed supplier for the planting window before the ground freezes. Cornell's Warren County guidance uses about three to four weeks beforehand.
• Mild winter: choose a locally adapted variety and ask whether it needs prechilling.
• Frozen or saturated soil: do not force a planting date just because the calendar says October.

2. Start with sound planting cloves

Buy labeled garlic sold for planting. Supermarket bulbs may be a poor climate match and can introduce disease. Hardneck types are commonly used in cold regions, while suitable softneck varieties are useful in milder areas; the cultivar and local experience matter more than the label alone.

Separate the bulb shortly before planting. Keep the papery skin intact and reject soft, visibly moldy or damaged cloves. This plan is for common garlic, Allium sativum, rather than elephant garlic.

3. Prepare a bed that drains

Choose full sun, remove weeds and loosen the planting area. Improve poor soil with finished compost as appropriate; use a soil test to guide fertilizer and lime decisions. Do not pour a full season's nitrogen into the bed now. Minnesota Extension notes that much of garlic's nutrient demand comes with spring growth.

If winter water sits in the bed, resolve drainage or choose another site. A deeper planting hole does not fix waterlogged soil.

4. Set spacing, then check the depth advice

Plant with the flat base down and the pointed tip up. A practical layout is about 6 inches (15 cm) between cloves and 12 inches (30 cm) between rows.

Depth recommendations vary with soil and winter exposure. The RHS ground plan covers the tip with about 1 inch (2.5 cm) of soil; colder-region guidance may specify deeper planting. Follow the instructions for your region and clarify whether a measurement means cover above the tip or total hole depth. Do not count mulch as soil cover.

5. Mulch and label the rows

Water if the soil needs moisture to settle around the cloves. In cold climates, apply the locally recommended winter mulch; Iowa State advises 4–6 inches of clean straw for its fall crop. Check moisture beneath it rather than watering on a fixed schedule.

Label the variety and planting date. In spring, loosen or move matted mulch that blocks emerging shoots. Growing on a balcony instead? Use the separate garlic container plan.
