Fall can be a great time to plant forage species especially along waterways and riparian areas that may be prone to excess water in the spring. Advantages include optimal use of spring moisture, reduction of your spring workload, access to waterlogged areas, lower salinity levels during spring germination. The disadvantages include the need for a higher seeding rate to offset seed and seedling mortality, restriction in species available to plant and the need to return to fertilize in the spring.
Tips for dormant/frost seeding:
- Determine your seed species by considering your end use, soil (type, pH, alkalinity, salinity and texture), climate, average available moisture, winter hardiness, seeding method, and yield potential.
- Complete weed control programs well ahead of time to ensure the reduction of the weed seedbank.
- Increase the recommended seeding rate by 20-30%.
- Avoid conditions that lead to soil crusting such as fine seedbeds, low organic matter and certain soil types such as heavy clays.
- Seed when the soil temperature is below 2 degrees.
- Direct seed if possible for uniform coverage and accurate seed depth.
- Use certified seed mixes to ensure seed quality and reduce the introduction of weed species.
