4 E. Erosion Control: 1. An oat or wheat cover crop will be sown along with the native grasses. F. Management: 1. Management (maintenance) plays a vital role in the eventual success of any native landscape installation, especially during the establishment period. 2. During the first growing season the project area may need to be mowed to control annual weed development. If a “closed” canopy of weed cover develops, it should be mowed to aid in the growth of the prairie seedlings by reducing competition. Mowing may also be necessary if the weeds are about to set seed. Optimum cutting height, depending on the wildflower species present, is typically 4 to 6 inches. Mowings done by PRI will be billed separately unless they are included as part of the installation contract. 3. In years following the first growing season, management services could include site monitoring, prescribed burning, mowing, spot spraying, spot mowing, herbicide wicking or hand weeding. PRI provides estimates for management services on an annual basis prior to the growing season. Most of these services are billed on a time and materials basis and the annual estimates are not exceeded without client approval. Some services such prescribed burning are provided as a lump sum cost. A summary of billing rates and materials costs will be provided with the estimate. G.
