2) Container grown plants: root ball is to be loosened and any circling roots pruned <br />prior to planting. <br />3) Plant installation: Planting pits must be twice as wide as the root ball and only the <br />depth of the existing root ball or else the bottom of the planting pits must be <br />compacted prior to planting to insure there is no settling. Plants are to be installed so <br />that the top of the root ball is at the soil surface. <br />4) Mulching: Planted area must be mulched with arborist chips or bark after planting <br />to help control weeds, prevent erosion, and conserve moisture. 2 -3 inches of mulch <br />is to be applied around all plants, keeping mulch 2 -3 inches away from the crown of <br />plants or the trunks of trees and shrubs. <br />5) When arborist chips or coarse bark mulch is applied, it should be used sparingly in <br />areas where spreading /vining groundcover is planted to encourage additional rooting. <br />Provide mulching details in the plan. <br />6) For planting live stakes, 3/4 of the length of the live stake must be installed below <br />the ground (with at least two nodes above ground). Specify that pilot holes are to be <br />used if necessary. <br />iii) Site /Soil Preparation Details: <br />1) No backfilling of individual plant pits with amended soils is allowed. Instead, the <br />entire planting site must be prepared and receive soil amendments prior to planting. <br />2) Soil must be loosened to at least 18 inches in depth and organic material, such as <br />compost (for example Cedar Grove or equivalent), tilled into the entire planting site <br />prior to planting. Alternatively, topsoil with at least 10% organic matter must be <br />imported and incorporated into planting area. <br />3) Provide specifications for compost and /or topsoil. <br />Page 11 of 11 <br />15 <br />
