Mulching Practices Clause Samples

Mulching Practices. The practice of adding mulch as a landscaping material around commercial buildings increases the population of invertebrates in or beneath the mulch. Mulch has benefits (moisture retention, decreasing soil loss, etc) but must be used selectively on the SSF Campus. EP-Yxx Engineering Practice Title Revision Number: 0.0 • Do not deep-mulch, (> than 2 inches (2.5-cm) at installation, and 1 inch (1.25- cm) after 60 days). Deep mulching is often used in residential neighborhoods, but the deeper the mulch, the larger the number of invertebrates that will live within the mulch. After the first year following initial installation of landscaping, mulch should be kept to about a 1.0-cm (3/4”) thickness and replenished as needed to this depth (i.e., as compared to deep mulching and replenishing less often). Within the Near Building Zone and where landscapes have matured beyond the first year following initial installation, and when mulch has broken down into the topsoil, refrain from adding additional mulch. • Inorganic mulch materials (e.g., crushed rock materials) are preferred. • Little differences exist relative to pest issues between selecting pine mulches and hardwood chipped mulch materials. • Mulching around tree trunks should also be kept to a minimum. Heavy mulching not only increases the invertebrate’s pest load to the immediate areas of the trees; it may also contribute to the premature death of some tree species. • Extensive, deep wide scale mulching is not “healthy” for building landscapes that must be hyper sensitive to pest pressures.
