• Add additional mulch regularly to maintain a layer no less than 2 inches (5 cm) deep at all times in shrub planters, tree wells,and beds where plants have not yet closed in over soil surface. For hillside native restoration area, maintain a layer of no less than 6 inches deep at all times, where plants have not yet closed in over soil surface. Decomposition of organic mulch is considered normal wear and tear, and replacement of decomposed mulch is required seasonally. Mulch is not required in areas where plant foliage completely covers the soil surface, such that the soil is not visible through the foliage. Any mulch found outside planter areas shall be returned to the planter on a weekly basis. • Mulch shall be uniform in color and appearance, and free of sticks or trash. Mulch may be compost, shredded fall leaves (with Owner's permission), or chipped or shredded wood, such as arborist chips, hog fuel,or play chips. Bark is undesirable, because it does not feed the soil as readily, may seal the surface preventing water entry, and may inhibit some plants' growth. When replacing existing mulch, use a mulch product that is similar in appearance to that already at the site. C.S. Turf care C.5.1. Mowing - Turf • Mowing schedule: Mow weekly during active growth periods (April-October) and at least once a month during winter. Keep mower blades sharp. • Clippings should always be left on lawn areas ("mulch-mowing" or "grasscycling"), except if this will create a large surface buildup, for instance if saturated soft soils have prevented mowing for several weeks in spring and the grass is very tall. Grasscycling returns about 2 lb. nitrogen per 1000 sq. ft. per year, and improves resistance to drought damage and weed invasion. • Modern "mulching" mowers are preferred because they chop clippings finely and blow the resulting mulch down to ground level, leaving a clean surface which is preferable, especially around building entrances where track-in can,be a problem. Effective mulching requires about 20% more engine power, and it may be necessary to slow down in heavy areas or wet weather to get the best mulching results. For these reasons, equipment that converts easily from mulching to side- throw (leaving clippings on surface) is the most adaptable to varying conditions and mowing schedules. • Mowing height: 2 to 2.5 inches high. • Mowing frequency: to causethe least stress on the grass plant, mow often enough to remove only one-third of the blade length (e.g., when the grass is 3" high mow it down to 2"). Also, mow un-irrigated summer-dormant turf regularly enough to remove weed seed heads before they mature. Start mowing in late winter as soon as grass begins to grow. On most lawn areas these rules will result in mowing
