ADDITIONAL SERVICES The City reserves the right to request additional services associated landscape maintenance. Prior to performance of any work the City will negotiate scope/pricing and the contractor must provide a quotation for the requested work that is to be approved in writing by the City. City written approval may be in the form of an "Authorization for Extra Work" form. 3. ANNUAL COLOR PLANTING AND MAINTENANCE SPECIFICATION Before each annual planting the area should be tilled 8 to 16 inches deep. Organic matter in the form of nitrified redwood must be incorporated to a depth of 8" of the top soil. The contract administrator may adjust this if adequate organic matter is already present in the soil but the successful bidder must be prepared to incorporate this organic matter at every color rotation. Organic matter must comprise 25% of the soil volume where the roots will be. This requires 2" of nitrified redwood tilled to an 8" depth. Apply 1.5 pounds of nitrogen per t000 sq. ft. as a complete low nitrogen material with a ratio of 1:2:1, 1:1:1, 1:2:2 or similar. Do not use a higher rate of nitrogen as this may result in excessive vegetative growth and a suppression of flowering. After establishment, fertilize as necessary to maintain a robust appearance and maximum flowering. After incorporating organic material and other supplements, the beds must be raked smooth and slightly mounded. Sticks clods and other material mast be removed from the bed. During planting gently crush the root mass with the fingers to stimulate root growth in the surrounding soil. Begin planting in the center of the bed and keep traffic in the worked soil to a minimum. Make the hole slightly larger than the root ball and set the plant at the same depth or slightly higher than it was growing in the container. Smooth out the soil around the plants after planting, including footprints. Water plants to a depth of 5 inches immediately after planting for 4" plant material (deeper for larger pots). Plants are to be rotated four times a year and are to be kept disease free and healthy on a consistent basis. There must be no dead or missing plants at any time and the beds must be kept in a weed free condition. Plants will be in 4" pots and will be planted in an 8" triangular spacing pattern. Rows must be in a straight alignment at the time of planting. Plant species that may be planted at different times of the year may include, but not be limited, to the following annual bedding plants as approved by the Director: Spring/Summer—April through October 1 Alyssum, Lobelia, Salvia, Marigold, Gloriosa Daisy, Penstemon, Cosmos, Dahlia, Impatiens, Begonias, Double Impatiens, Petunia, Verbena, Vinca rosea (periwinkle) Zinnias • Fall/Winter Iceland poppies, Pansies, Viola, Stock, Snapdragons, Primroses, Ranunculus City of Santa Ana RFP 16-063 Page 50 25K-34
