regulations in accordance with the latest edition of the Florida Department of Agriculture ' s " Grades and Standards for Nursery Plants " . Except where a lesser grade might be specifically specified in the plans , ensure that the minimum grade for all trees and shrubs is Florida No . 1 . Ensure that all plants are the proper size and grade at the time of delivery to the site , throughout the project construction period and during any designated plant establishment period . Ensure that plant materials are true to type and species and that any plant materials not specifically covered in Florida Department of Agriculture ' s " Grades and Standards for Nursery Plants " conform in type and species with the standards and designations in general acceptance by Florida nurseries . Ensure that plant materials are shipped with tags stating the botanical and common name of the plant . 580 -2 . 1 . 3 Inspection and Transporting : Move nursery stock in accordance with all Federal and State regulations therefor , and accompany each shipment with the required inspection certificates for filing with the Engineer . 580 -2 . 2 Water : Water used in landscaping operations may be obtained from any approved source . Ensure that water is free of any substance which might be detrimental to plant growth . The use of effluent water is subject to approval and must meet all Federal , State and Local requirements . 580-3 Specific Requirements for the Various Plant Designations . 580 -3 . 1 Balled -and -Burlapped Plants ( B & B ) , and Wired Balled -and -Burlapped (WB & B ) : 580 -3 . 1 . 1 General : Properly protect the root ball of these plants until planting them . The Engineer may reject any plant which shows evidence of having been mishandled . Set the B & B and WB & B plants then remove the top 2/ 3 of all wire , rope , and binding surrounding the plant . Remove the burlap from the top 4 inches [ 100 mm] of the root ball . Do not disturb the root ball in any way . Bare root material is not allowed for substitution . At least 90 days before digging out B & B and WB & B plants , root- prune those 1 1 /2 inches [38 mm] or greater in diameter and certify such fact on accompanying invoices . 580 -3 . 1 . 2 Provisions for Wiring : For plants grown in soil of a loose texture , which does not readily adhere to the root system ( and especially in the case of large plants or trees ) , the Engineer may require WB & B plants . For WB & B plants , before removing the plant from the excavated hole , place sound hog wire around the burlapped ball , and loop and tension it until the tightened wire netting substantially packages the burlapped ball such as to prevent disturbing of the loose soil around the roots during handling . 580 -3 . 2 Container-Grown Plants ( CG ) : The Engineer will not accept any CG plants with roots which have become pot- bound or for which the top system is too large for the size of the container. Fully cut and open all containers in a manner that will not damage the root system . Do not remove CG plants from the container until immediately before planting to prevent damage to the root system . 580 -3 . 3 Collected Plants (Trees and Shrubs ) ( C ) : Use C plants which have a root ball according to " Florida Grades and Standards for Nursery Plants " . Do not plant any C plant before the Engineer' s inspection and acceptance at the planting site . 48 Technical Specifications F :\Public Works\ENGINEERING DIVISION PROJECTS\0744-8th St-US1 to 6th Ave\Admim\bid documents\0744 CONTRACT DOCUMENTS\Technical Specifications . doc
