Management (maintenance) plays a vital role in the eventual success of any native <br />landscape installation, especially during the establishment period. <br />2. During the first growing season the project area may need to be mowed to control <br />annual weed development. If a "closed" canopy of weed cover develops, it should be <br />mowed to aid in the growth of the prairie seedlings by reducing competition. Mowing <br />may also be necessary if the weeds are about to set seed. Optimum cutting height, <br />depending on the wildflower species present, is typically 4 to 6 inches. Mowings done <br />by PRI will be billed separately unless they are included as part of the installation <br />contract. <br />3. In years following the first growing season, management services could include site <br />monitoring, prescribed burning, mowing, spot spraying, spot mowing, herbicide <br />wicking or hand weeding. PRI provides estimates for management services on an <br />annual basis prior to the growing season. Most of these services are billed on a time <br />and materials basis and the annual estimates are not exceeded without client <br />approval. Some services such prescribed burning are provided as a lump sum cost. A <br />summary of billing rates and materials costs will be provided with the estimate. <br />L.
