Utah growing guide: zones, planting dates and where to start
How Utah zones change planting dates, with spring dates for its main growing region.
Not yet expert-reviewed. Written by BAU Farm Intelligence from public extension and agency sources. Check dates and program details with your local extension office.
Zones across Utah
Utah covers USDA Zones 6b–9a on our calendar. A date that works in one part of the state can be weeks off in another, so plant by your zone, not the state.
- Zone 6b — Logan and Cache Valley. Average last frost 04/24, first frost 10/08 (about 167 frost-free days).
- Zone 7a — Salt Lake City and the Wasatch Front. Average last frost 04/15, first frost 10/15 (about 183 frost-free days).
- Zone 8a — Moab and the canyon country. Average last frost 03/28, first frost 11/05 (about 222 frost-free days).
- Zone 9a — St. George and the Virgin River valley. Average last frost 02/25, first frost 12/01 (about 279 frost-free days).

Where to sell in Utah
- State buy-local program: the Utah Department of Agriculture and Food runs Utah's Own. Members can be listed for grocery, restaurant and school buyers looking for in-state product — ask about joining and any marketing directories.
- Established market: Downtown Farmers Market (Salt Lake City). Visit on a market morning and talk to the produce dealers before you plant, not after harvest.
- Farmers markets, CSAs and on-farm stands: the USDA Local Food Directories list them by state, so you can see who already sells near you and which markets still need your crop.
- Schools and institutions: ask your state's farm-to-school contact (usually through the agriculture or education department) what they buy and when.
- Buyers on BAU: buyers post what they need on the marketplace, and you can list your crop window there for free.
Call before you count on any buyer: programs and market hours change, and a price talked through in winter is worth more than one found at harvest.
Farm taxes in Utah
- Income tax: Flat state income tax.
- Sales tax on inputs: Farm inputs and equipment are exempt; give the vendor Form TC-721 (Exemption Certificate).
- Farmland property tax: Farmland Assessment Act (Greenbelt): farmland is assessed on its productive value; apply through the county assessor.
Rates and forms change. Confirm with the state revenue department or a farm tax preparer before you file — this is a plain-language guide, not tax advice. Our farm tax estimator covers the federal deductions every state shares.
