If the cause can be determined, it should be eliminated before any reinstallation. Fertilization The objective of fertilizing at a BIMP is to secure optimum vegetative growth rather than yield (often the objective with other activities such as farming). Inferrhile soils should be amended before installation and then fertilized periodically thereafter. Fertilizer, can be composed of minerals, orgganic matter (manure), compost, green crops, or other materials. Irrigation/ Watering Watering of the vegetation can often be required during the germination and establishment of the vegetation, as well as occasionally to preserve the vegetation through drought conditions. This can typically be accomplished by pumping water retained in the BMP or from the stream, iimstalling a permanent irrigation system or frostproof hose bib, or using portable water trucks. Mulching Mulching should be used to maiinitain soil temperature and moisture, as Well as site aesthetics. A half inch layer is typically adequate. Ideally, mulch shouldl The removed before winter to prevent an infestation of rodents. Weeding Weeding is often necessary in tliie first growing season, particularly if herbaceous grasses are outcompeting the young woody vegetation growth. The need for:'�weeding may be largely eliminated by minimizing the amount of seed used for temporary erosion, control. Weeding may also be regquired if, over time, invasive or undesirable species are entering the site and outcompeting plants, that are specifically involved in tlhe treatment of the stormwater. Disease Control Based on monitoring observatiorms, either insecticides or (preferably) organic means of pest and fungal control should be used. Mowing Mowing of perennial herbaceous grasses and wildflowers, especially once seed heads have set, promotes redistribution of seed for this selfsustaining system. Moowing should be carefully controlled, however, especially when performed for aesthetics. As adjacent property owners and customers in general learn more about BMPs, their vision of what is aesthetically pleasing can change. Grasses, in healthy herbaceous stands, should never be mown more than once per year. BMP ELEMENT POTENTIAL PROE;'LEMS HOW TO REMEDIATE THE PROBLEM The entire BMP Trash/debris is present.
