southeast corner of the building). They shall be pruned to keep free from window <br /> recesses and shall climb no higher than the first story (12' above main floor). <br /> Groundcovers <br /> • Groundcover shall be maintained in a healthy, vigorous growing condition. <br /> • Any groundcover found to be dead or missing shall be replaced with plant material of <br /> identical species at the landscape maintenance contractor's expense, unless the loss <br /> was due to excluded damage. <br /> - Keep groundcover trimmed to edge of sidewalks, curbs, and paved areas on a <br /> monthly basis. Do not create vertical edges when pruning groundcover. Cut the edges <br /> at an angle /--\ for a more natural appearance and healthier plants. Prune so <br /> groundcover just overlaps adjoining paving; an open mulch strip here allows weeds <br /> to take hold and trash to accumulate. <br /> • If regular foot traffic through a planter is preventing the groundcover from <br /> reaching full coverage of the soil, contact the owner's authorized representative to <br /> discuss options for redirecting the foot traffic. Consider installing pavers, stepping <br /> stones, a concrete walk, a gravel path, and/or barriers to redirect pedestrians. <br /> C.3. Fertilizer - Trees, Shrubs, Vines and Groundcovers <br /> • Do not fertilize plantings in the swale (rain garden/bio-retention planters). <br /> • Fertilizers shall be either organically derived or slow-release synthetic products, to <br /> minimize water pollution and feed plants over a longer period of time. <br /> • Granular slow release or organic fertilizer shall be 5-5-5 formulation or similar, <br /> applied per label rate for plant type. Water immediately after applying to move the <br /> fertilizer into the soil and wash the fertilizer off of plant surfaces. <br /> • When applying granular fertilizers to drip-irrigated areas, the fertilizer must be <br /> washed in by hand or rainfall before turning on the drip system. Running the drip <br /> system immediately after application will push the fertilizer away from the <br /> emitters, resulting in a high concentration of fertilizer at the edge of the wetted <br /> zone. This highly-concentrated fertilizer can kill or damage plants. It is <br /> recommended that granular fertilizers be applied to drip-irrigated areas only in <br /> early spring, just prior to a moderate rainfall. <br /> C.4. Mulch layer - Trees, Shrubs, Vines and Groundcovers <br /> Maintaining a deep layer of mulch greatly reduces the labor and materials needed to <br /> control weeds, reduces water use, and helps the plants stay healthy. <br /> r <br />
