mtegrated P ant Management : An assessment of each planting area ' s soil is recommended to periodically determine the nutrient levels needed to sustain healthy, vigorous plant growth . Palms , shrubs , trees and turf areas should be fertilized in such a manner and frequency to ensure that the plant material remains healthy and vigorously growing . Establishment of an integrated plant management program is encouraged to ensure healthy plants which are free of disease and pests . Mulching : Mulch planting beds in such a manner as to : prevent weed growth ; retain moisture to the plants ; protect against soil erosion and nutrient loss ; maintain a more uniform soil temperature ; and improve the appearance of the planting beds . Avoid mulch mounded up on the trunks of trees , palms , and the base of shrubs to encourage air movement in this area which aids in lowering disease susceptibility. Cypress mulch is prohibited on state right of way . Pruning : All pruning , and the associated safety criteria, shall be performed according to American National Standard Institute ANSI A300 standards and shall be supervised by an International Society of Arboriculture (ISA) Certified Arborist . Pruning shall be carried out with the health and natural growth of plant materials in mind, and to specific pruning heights maintaining clear visibility for motorists , and vertical clearance for pedestrian, bicyclist, and truck traffic where applicable . Visibility windows must be maintained free of view obstructions and all trees and palms (with particular attention to fronds and fruit) maintained to prevent potential roadway hazards . The specific pruning heights are determined by understanding the designer ' s intent when selecting and placing the plants . The intended mature maintained height and spread of plants should be noted on the planting plans . ( See Specific Requirements and Recommendations per Approved Landscape & Irrigation Design for these guidelines) . Staking and Guying_ All staking materials , except for replacements , are removed by the completion of FDOT warranty period or at one year (whichever comes first) . Any subsequent staking and guying activities by the Agency must adhere to FDOT Design Standards guidelines ( See Index 544) . The Agency shall closely monitor staking and guying attachment materials so that they are securely fastened to avoid potential roadway hazards . Turf Mowing : All grassed areas are to be mowed and trimmed with sufficient frequency to maintain a deep , healthy root system while providing a neat and clean appearance to the urban landscape . Litter Control : The project site shall remain as litter free as practicable . It is recommended to recycle this litter to avoid unnecessary waste by its reuse .
