In Kentucky, the ideal time to frost seed is between February 10 and March 1, with mid-February preferred. These types of seeds are usually from temperate zones and have a very tough seed coat that will only crack after a hard frost. The frost seeding method allows seeds to be inter-seeded into undisturbed soils by scattering seed on top of the ground. Dormant seeding means planting in early winter, before ground has frozen, but … Frost seeding works best if pasture residue has been removed prior to broadcasting the seed to allow the seed to reach the soil surface. If not, you will not achieve good seed-to-soil contact essential to success during and after frost seeding. Legumes are properly inoculated with the correct strain of Rhizobium bacteria, for optimal nitrogen fixation. Otherwise in nature fresh seed that falls to the ground would germinate in the fall and the new seedlings would perish with the cold. Conventional grain drills will work as long as they penetrate the soil surface and adequately cover the seed. If it is borderline to late, better options are a drill , very light tillage, aggressive harrowing, or best and cheapest of all, mobbed livestock impact. Early morning frost seeding, before the soil surface begins to thaw, is recommended. Say you have a 30% coverage of a #thin #lawn , we slit seed destroying the existing lawn and have a 50% germination rate. How to frost seed: Frost seeding is best accomplished by spreading seed with broadcast spreaders at a time of the year when the soils are freezing and thawing on a daily basis. you only gained 20% at what cost. What is Frost Seeding? What works with this technique is the freeze-thaw process in late winter/early spring. Seed-to-soil contact is always critical to success. On the other hand, it is very difficult to establish most grasses and alfalfa by broadcasting or frost seeding. For years, we've recommended red clover, white clover, and perennial ryegrass as the products of choice for frost seeding. A general rule of thumb is that the better your cereal crop is, the worse your companion crop will be and vice versa. Before we dive too far into the strategy, lets cover the basics of why and how to frost seed a food plot. (See “ When to Plant ”) Fall planting in the Upper Midwest begins in mid-October. When it comes time to seed a new lawn or landscape, you have to take into account many factors, from the types of grass that grow best in your landscape to the appropriate planting techniques. Frost seeding is the easiest method to add new forage legumes or grasses to pastures, and is likely the least expensive method, as well. The broadcast seeder is correctly calibrated. To increase this method's success, spread seed on the thinnest pasture sod areas first and on areas where bare soil has been exposed due to heavy grazing or disturbance. Why do you need to select your seeds carefully? Sometimes this works and others times it does not. We recommend Jonathan Green Black Beauty grass seed. Fundamentals of Frost Seeding Food Plots. Germination normally occurs within 7 to 21 days under suitable moisture and soil temperatures conditions. Grass seed typically takes a few weeks to sprout and then several more weeks before it is strong enough to withstand frost. Clover typically works the best because the seed is heavier and can work into the ground with a little more ease. If the soil surface is "slimy", wait to seed until you get another morning when the soil has frozen again. Frost-seeding works best on loam or clay-based soils; sandy soils will not work as well because there is not enough soil movement during freeze-thaw cycles on sands. Once you have a site ready for frost seeding, the easy part begins. See Jason explain step by step the benefits and how to properly frost seed your perennial food plots. As the soil dries, the pockets collapse and cover the seed. Now, with the advent of Frosty Berseem Clover, we've got another tool in our frost seeding toolbox. The natural freeze and thaw cycle of freezing soils will create small cracks or pockets, perfect for catching and holding grass seed. An early spring sewing is the best planting method for these areas. Frost seeding is the same as any other type of seeding or planting- seed-to-soil contact is critical. The best candidate for frost seeding is areas with bare or exposed soil. Don’t frost seed an area that has a lot of competing vegetation! Most often, we recommend using frost seeding to introduce forage legumes into an established stand. Frost seeding cover crops generally involves incorporating clover species into a dormant cereal crop. Think of … The cycle of freezing and thawing in the coming weeks will help the seeds set and any snowfall will result in even soil compressing, which will aid in germination. Select a good mix of seeds for your lawns. Frost seeding works best with legume seeds typically, because it is easier for smaller seeds to drop to the soil surface than it is for the larger, but lighter grass seeds. From seeding new lawns to repairing rough spots and renewing existing turf, proper timing separates sweet success from something less. Obviously, only seeds that can handle a period of cold are going to self-seed in these gardens, and you will need to ensure that you have allowed the seed heads to mature before your first frost. Once seeding is complete, lightly rake the surface to cover seeds. Frost seeding is a form of dormant seeding, overseeding moist soil before freezing weather. (The seed is also too large for optimal frost seeding.) Frost seeding requires the soil to be thawing, freezing and heaving. A typical tall fescue seeding rate is 5 to 6 pounds of seed per 1000 square feet. Frost seeding, or sometimes called snow seeding, allows you to use the thaw, freeze, and thaw cycle that occurs during late winter and early spring. Residue removal is best done by grazing late the previous fall. This will typically be in February through early March for most areas in Illinois. If the ground is prepared properly, and the seed applied in a timely manner, frost seeding is a very viable option. If frost or dormant seeding is done into an existing stand, there has to be enough bare soil exposed that most of seed can reach the soil. For sandy soils, use a no-till or conventional grain drill to apply the seed into the pasture sod in April. Understanding your options and getting timing right helps you seize every opportunity for seeding success. We have seen great results with frost seeding as is non-invasive and will not tear up any existing turf as a slit seeder or aeration would. FROST SEEDING FOOD PLOTS. Native grass seed sown earlier may germinate in ten days in unseasonably warm weather. Seeds can be planted in the fall, spring or dead of winter. Frost seeding earlier than March will also result in seed loss to birds, rodents, etc. Frost seeding fits into the last category. Obviously, frost seeding is only possible in areas where the ground actually freezes, otherwise you are simply wasting seed. The seeds get caught in the cracks created by the heaving process, and this, is in essence how the seeds are “planted.” For best results and to make the most of your investment, select cultivars recommended on the Turffiles website. 6. Red clover should be spun on at 3-4 lbs/A if frost-seeded every year, and 6-8 lbs/A if every other year or a first-time seeding. The best time to seed is while the ground is still frozen but thawing on top during the day – usually February to April depending on location. One of the key considerations involves the effects of the temperature on the seed and the newly sprouted grass plants. Too much seed can be as detrimental as under-seeding. If you think about it, it makes sense. 5. When thickening grass-clover sods, it is best to plant the grass and clover seed with a no-till drill. Keep off the lawn and allow the weather to do your dirty work. Your best time for planting grass seed depends on the type of lawn grass you grow and where you live. If this occurs, seedlings may be winter-killed. Table 1 has a good overview of seeding rates and expected established plant populations when frost seeding. The process of frost seeding is fairly simple. The freezing and thawing action of the soil works the seeds into the soil where they can germinate. Paying attention to the recommended planting guide on your grass seed will help you determine the best time plant your grass seed and the best products to use. In some years, there is an extended cycle of freeze-thaw, but fortunately, early spring rains also helps with seed coverage on bare areas. Legumes have a much better success rate than grasses. As the days get above freezing and nights are below freezing, this action works the seeds down into the soil in preparation for germination. Frost-seeding is the broadcasting of forage seed on existing pasture in late winter, with the goal of freeze-thaw cycles shallowly covering the seed.
