a. Dormant seedings are made after soil temperatures are cool enough to <br />prevent germination. Procedures for applying needed lime and fertilizer, <br />seedbed preparation, seeding and mulching are the same as during other <br />seeding periods. <br />b. An alternate method of dormant seeding is to apply neede lime and <br />fertilizer, prepare a seedbed, and apply and anchor mulch. Sow seed as a <br />dormant seeding over the mulch during the time period shown in the <br />Optimum Seeding Period Table. Do not seed on ice, or snow deeper than <br />2 inches. Double seeding rates when using this method. <br />3.13 Optimum Seeding Period <br />urassluegume 5 ecies Spring Summer Dormant <br />Cool Season Grasses 4/1-5/50 8/1-9/15 11/1-4/1 <br />Warm Season Grasses 5/15-6/20 - 11/1-4/1 <br />Alfalfa; Red Clover 4/1-5/20 8/1-8/20 11/1-4/1 <br />Birdsfoot Trefoil; <br />Crownvetch 4/1-5/20 - 11/1-4/1 <br />3.14 Establishment Management: <br />a. Control undesirable broadleaf weeds, weedy grasses and woody plant <br />growth as needed. Clipping should be done before the weeds begin to <br />compete for moisture and prior to weed seeds maturing. <br />b. Herbicides may be used to control some species of weeds. Optimum <br />control will be obtained when weeds are in early growth stages. Herbicide <br />applications should be delayed until grasses reach the three -leaf stage. <br />Do not apply herbicides to seeding mixtures that include legume. <br />Herbicides shall be applied in accordance with authorized, registered uses <br />and directions on the label. The individual who applies herbicides is <br />responsible for complying with federal,state and local laws and regulations <br />governing the use of herbicides. <br />4.0 General Recommendations In The Establishment Of Grass: <br />Seedbed Preparation - Area to be seeded should be well worked: the same as for <br />a standaru lawn seeding. Harrow or pack the seedbed prior to seeding to break up <br />large c,cds and firm the seedbed. The prepared seedbed must be scft encugh to <br />permit covering the seed and anchoring mulch yet firm enough to prevent burying <br />seeds too deep. For example, the soil should be firm encugh to support the weight <br />of a person without sinking into the soil more than 1 /2 inch. The entire seedbed <br />should be uniform, friable and well packed. In some cases, heavy land roller or culti- <br />packer may be needed to get the desired compaction. <br />
