Broadcast seeding is not recommended unless there are <br />' small areas inaccessible to drills. In small areas, broadcast seeding may be <br />accomplished by hand or with manual operated seeders. The seed should be <br />covered 1/4 to 1/2 inch deep by raking or harrowing and the broadcast seeding <br />' rate must be doubled. <br />Seeding Dates: Fall seeding is recommended, after October 15th and prior to <br />April 15th. This will keep the seed from germinating before adequate moisture <br />' and warm temperatures are available. Mulching may be required to protect slopes <br />from erosion and protect seedlings during establishment. For the Bite conditions, <br />seeding should be accomplished first and then mulching material applied second, <br />' please refer to Mulching Standards and Specifications. <br /> <br />1 <br /> <br />~J <br />
