What’s My Zone?
PLEASE NOTE: Much of southern Idaho is in USDA Hardiness Zone 6, so these instructions will mostly reflect Zone 6 recommendations. If you are reading from a different location, we really encourage you to adjust your planting window based on your local USDA Zone.

Let’s Get Into it!
In our area, we recommend planting garlic cloves from mid‑September to early October, about 6–8 weeks before the ground freezes.
Why does timing matter?
Too early, and you risk premature sprouting. Too late, and the roots will not develop enough before the winter freeze.
Preparing the Soil
Loosen the soil up to a depth of 18 inches.
Mix in some compost to amend the soil. You can supplement in some organic matter like leaves, peat moss, manure, and bark for any soil that has become heavy from clay.
Garlic likes full sun (6+ hrs), ample water, and an area free of weeds!
Planting Steps
- Separate cloves from bulbs; keep papery skin on.
- Plant depth: 3 inches deep, pointy end up!
- Spacing: Rows 12-16 inches apart for airflow. Cloves 6 inches apart.
- Mulch: Apply 2–6 inches of straw, hay, grass clippings or shredded leaves after planting to insulate roots and retain moisture. This is most important for cold areas, so if you live in a warmer pocket, you can safely reduce your mulch application.
- Water: Give a deep soak after planting; avoid overwatering in winter.
- Spring: Remove excess mulch if needed; keep soil moist.
- Harvest: Mid‑ to late summer (July–August) when lower leaves yellow
- Cure: Dry in a warm, well‑ventilated place for 2–3 weeks, then store in a cool, dark, dry spot
