Frost seeding is a practical technique for forage managers looking to repair pastures damaged by drought and hoof traffic. The best time for frost seeding is now through St. Patrick’s Day, as the natural freeze-thaw cycle of the soil helps embed seeds into the ground.
When water in the upper soil layer freezes, it expands and pushes soil upward. As it thaws, the soil settles, helping seeds make good soil contact for germination. This process allows seedlings to establish early without disturbing wet spring soils.
Livestock can also aid in frost seeding. Hoof traffic helps press the seeds into the soil, improving contact and germination rates. However, animals should be removed once seeds start germinating to prevent damage. In most cases, livestock can return 30-45 days after germination.
Frost seeding works well with both legumes and some grasses. Choosing high-quality seed and applying it at recommended rates ensures better establishment. Seeding can be done manually, using a hand crank, a seed broadcaster on an ATV, or even via aerial application with drones or planes.
While frost seeding is effective, it requires proper grazing management. Giving new seedlings enough time to establish through rest and recovery is crucial. Additionally, weed pressure may increase due to bare soil from drought conditions.
Some herbicides used for weed control may harm young legume seedlings, so delaying legume seeding until later in the season may be beneficial.
Every farm is unique, and forage management should be tailored to specific soil and pasture conditions. Farmers needing assistance with seed selection or pasture planning can consult their local Extension office for expert advice.
