CRP seeding deadlines by state
CRP seeding deadlines are set by each state's NRCS office and written into your conservation plan. Most states allow dormant seeding from November 1 and require spring planting finished between May 1 and June 30 — the state table below shows the typical dates, and your county FSA office has the final word.

| North Dakota | Oct 15 | Jun 1 | CRP seed in North Dakota → |
| Kansas | Nov 15 (dormant) – Dec 1 | May 1 (west) – May 15 (east) | CRP seed in Kansas → |

| Texas | Dec 1 – Feb 15 (cool-season window) | Mar 15 (north) – Apr 1 (south) | CRP seed in Texas → |
| Colorado | Nov 1 – freeze-up | May 15 (plains) | CRP seed in Colorado → |
| Montana | Oct 15 – freeze-up | Jun 1 | CRP seed in Montana → |
| Oklahoma | Nov 15 – Feb 15 | Mar 31 (west) – Apr 15 (east) | CRP seed in Oklahoma → |
| Wyoming | Oct 15 – freeze-up | May 15 – Jun 1 | CRP seed in Wyoming → |
State notes
Iowa NRCS commonly requires spring seeding complete by early June; dormant seeding runs Nov 1 through freeze-up and resumes at spring thaw.
Reliable snow cover makes frost seeding viable Dec–Feb. Spring cutoff is earlier in northern counties.
Frost seeding works well statewide. Warm-season grass plantings should finish by early June.
Southern Illinois allows later spring dates; pollinator plantings are strongest as dormant seedings.
Missouri spans a wide climate band — Bootheel counties run weeks ahead of the Iowa border. Confirm dates by county.
Western Nebraska's drier climate pushes spring seeding earlier; dormant seeding is the default on most acres.
Frost seeding is reliable statewide. Western counties lean heavily on dormant seeding for moisture.
Short season: dormant seeding starts as soon as soils cool in mid-October, and spring windows close by early June.
Kansas final spring dates are earlier than Corn Belt states because summer heat arrives fast. Dormant seeding Dec–Feb is standard.
Upper Peninsula dormant seeding starts earlier. Frost seeding is reliable statewide Dec–Feb.
Spring seeding after mid-June enters summer drought risk; dormant is preferred for forb-rich mixes.
Filter strips and CP42 both perform best as dormant or very early spring seedings.
Texas CRP planting runs winter-early spring, not the Midwest pattern. Summer planting fails; fall planting is limited to specific practices.
Eastern plains CRP follows the dryland pattern: dormant seeding into frozen ground, or early spring before moisture runs out.
Very short effective season. Dormant seeding after soils cool is the standard; spring moisture is the limiting factor.
Winter dormant seeding is the primary window. Spring dates close earlier than northern plains states.
High-elevation and dryland sites depend on dormant seeding; confirm practice-specific dates with the state NRCS office.
How to plan backward from your deadline
- 6 months out: confirm your practice code and approved seeding period with your county NRCS office, then request mix quotes. High-diversity CP25 and CP42 forbs sell out by late summer.
- 60–90 days out: place your seed order and line up a drill or broadcaster. Custom blending and cleaning take 2–4 weeks in peak season.
- 2–4 weeks out: finish site prep — herbicide burndown, residue management, and a firm seedbed. Seed waits; weeds don't.
- Deadline week: if weather pushes you past the final date, call your county FSA office before it passes. Documented weather extensions are common; silent misses are not.

Frequently asked questions
Missing the final planting date in your conservation plan can trigger a compliance review, delay cost-share payment, or require you to reseed in the next approved window at your own expense. Contact your county FSA office immediately — extensions are sometimes granted for weather, but only if you ask before the deadline passes.
No. Each state NRCS office sets its own seeding dates by practice code, and counties within a state can differ by several weeks. Northern plains states start dormant seeding in mid-October, while Texas and Oklahoma run a winter December-to-February window. Always confirm against your written conservation plan.
Dormant seeding can only begin once soil temperature at 2 inches stays below 50°F — typically November 1 in the Corn Belt, mid-October in the Dakotas and Montana, and December in Texas and Oklahoma. Seeding into warmer soil risks fall germination and winterkill.
Final spring planting dates range from May 1 in western Kansas to June 30 in southern Missouri, with most Corn Belt states at June 1–15. Your conservation plan lists the exact date for your practice and county — it controls over any general guide.
Order 60–90 days ahead for standard mixes and 4–6 months ahead for high-diversity CP25 and CP42 mixes. Some forb species have limited harvests and sell out by late summer, so landowners targeting a November dormant seeding should have quotes in hand by August.
