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 />
