Garlic

Garlic runs on a different calendar than everything else in the vegetable garden. You plant it in fall — typically 4 to 6 weeks before your first fall frost, not your last spring frost — and it sits dormant through winter before pushing up green shoots in early spring. That reversed timeline is the thing most first-time garlic growers miss. The directSowWeeksBeforeLastFrost field for garlic is set to -24 to represent a fall planting; the actual timing to aim for is 4 to 6 weeks before your first expected fall frost, so roots can establish before the ground freezes.

The first decision you'll make is hardneck versus softneck. Hardneck varieties — Music, German Extra Hardy, Spanish Roja, Chesnok Red — produce a central woody stalk called a scape in early summer, which curls as it matures. Cut the scape before it straightens and the plant puts more energy into the bulb. Hardnecks tend to have more complex flavor and larger cloves but a shorter storage window, typically four to six months. Softneck types like Inchelium Red don't produce scapes, store up to a year, and are the variety you'll find braided in markets. If you're in a zone 7 or warmer climate, softneck varieties tend to do better — hardnecks need a genuine cold period to form well-separated cloves.

Plant individual cloves with the flat root end down and the pointed tip up, about 2 inches deep, 6 inches apart. Mulch the bed with 4 to 6 inches of straw after the ground has started to chill — this insulates roots through winter without preventing the cold exposure the bulbs need. In spring, the mulch can stay in place as the shoots emerge through it, suppressing weeds through the long growing season ahead.

The most common failure mode is basal rot, caused by Fusarium culmorum or related fungi. It shows up as yellowing leaves and a pink-brown discoloration at the base of the cloves, often after a wet, mild winter. Good drainage is the main prevention; planting disease-free seed garlic from a reputable supplier is the second. Don't save and replant cloves from a bed where you've seen rot — the pathogen persists in the soil. Another common mistake is harvesting too late. Once the lower third to half of the leaves have turned brown and died back, the bulbs are ready. Leave them longer and the wrapper sheaths begin to deteriorate, shortening storage life.

Harvest when half the leaves are still green and half have browned — roughly 24 weeks after fall planting, or whenever that window falls in your local calendar. Lift with a fork rather than pulling by the stem, which can bruise the neck and invite mold during curing. Cure in a dry, shaded spot with good airflow for three to four weeks before trimming and storing. Hardnecks can bruise and begin to dehydrate faster than softnecks, so use those first. The cloves from your best bulbs can go back in the ground next fall — garlic rewards the grower who pays attention to which plants performed best.
