Mulching - Mulch on slopes steeper than 3: 1, or where needed. Once the seed is planted, mulching <br />the area with' / to 1 ton per acre of certified weed free straw or grass hay can aid establishment. Apply <br />straw at a rate to get 80 -100% ground cover, enough to hold soil moisture, but not excessively thick <br />which will slow soil temperatures from warming in the spring. Using grass hay has the added benefit <br />of adding additional desirable seed from the grass in the hay. Hydro- mulching may also be used. <br />Erosion control blankets may be used following manufacturer's specifications. <br />Weed Control- Annual weeds can be controlled initially via mowing. A broad spectrum herbicide <br />can be used later in the summer once the grass is adequately established to prevent damage from the <br />herbicide. It is usually recommended to wait until the grass is in the 3 to 4 leaf stage before applying <br />any herbicide. Follow the manufacturer's label for more detailed instructions. <br />Maintenance - Two growing seasons will be needed to determine success or failure of the seeding. <br />Full grass establishment takes time. Managing weed competition will enhance establishment. Newly <br />planted grass needs time to develop a significant root system in order to compete against weeds. Defer <br />livestock grazing for a least two growing seasons or until plants are well established. <br />The above recommendations are all taken from the Colorado NRCS Field Office Technical Guide. <br />
