Examine areas with Installer present to receive exterior plants for compliance with requirements and conditions affecting installation and performance. 1. Locate above and below-grade utilities and perform Work in a manner to prevent damage, hand excavate as required. 2. Verify that required utilities are available and ready for use. 3. Test drainage of beds and pits by filling with water twice in succession. Notify Architect of water retention for longer than 24 hours. 4. If conditions detrimental to plan growth are encountered, such as rubble fill or adverse drainage conditions, notify Architect before proceeding. B. Proceed with installation only after unsatisfactory conditions have been corrected. 2. PREPARATION A. Protect structures, utilities, sidewalks, pavements, and other facilities, and lawns and existing exterior plants from damage caused by planting operations. 1. Protect grade stakes set by others until directed to remove them. B. Lay out individual tree and shrub locations and areas for multiple plantings. Stake locations with surveyor’s flags, outline planting bed areas, adjust locations when requested, and obtain Architect's acceptance of layout before planting. Make minor adjustments as required. 1. Notify Architect when staking and bed layout is complete and allow one week for adjustments. 2. Plant material installed prior to Architect’s approval of staking and bed outlines is subject to relocation at Contractor’s expense. C. Apply antidesiccant to trees and shrubs using power spray to provide an adequate film over trunks (before wrapping), branches, stems, twigs, and foliage to protect during digging, handling, and transportation. 1. If deciduous trees or shrubs are moved in full leaf, spray with antidesiccant at nursery before moving and again two weeks after planting. D. Wrap trees and shrubs with burlap fabric over trunks, branches, stems, twigs, and foliage to protect from wind and other damage during digging, handling, and transportation. EXCAVATION FOR TREES AND SHRUBS A. Before planting, restore planting beds if eroded or otherwise disturbed after finish grading. B. Pits and Trenches: Excavate circular pits with sides sloped inward per planting detail on the drawings. 2. If drain tile is shown or required under planted areas, excavate to top of porous backfill over tile. C. Subsoil removed from excavations is to be used as backfill. D. Obstructions: Notify Architect if unexpected rock or obstructions detrimental to trees or shrubs are encountered in excavations. 1. Hardpan Layer: Drill 6-inch- diameter holes, 24 inches apart, into free-draining strata or to a depth of 10 feet, whichever is less, and backfill with free-draining material. E. Drainage: Notify Architect if subsoil conditions evidence unexpected water seepage or retention in tree or shrub pits. F. Fill excavations with water and allow to percolate away before positioning trees and shrubs. TREE AND SHRUB PLANTING A. Before planting, verify that root flare is visible at top of root ball according to ANSI Z60.1. B. Set balled and burlapped and container grown stock plumb and in center of pit or trench with top of root ball 1 inch above with adjacent finish grades. 4. Remove burlap and wire baskets from tops of root balls and partially from sides, but do not remove from under root balls. Remove pallets, if any, before setting. Do not use planting stock if root ball is cracked or broken before or during planting operation. 5. Place fertilizer and mycorrhizal inoculants prior to backfilling. Provide one ounce of inoculants per inch of stem caliper. 6. Plumb before backfilling and maintain plumb while backfilling. 7. Place planting soil mix around root ball in layers, tamping to settle mix and eliminate voids and air pockets. When pit is approximately one-half backfilled, water thoroughly before placing remainder of backfill. Repeat watering until no more water is absorbed. Water again after placing and tamping final layer of planting soil mix. C. Set and support bare-root stock in center of pit or trench with trunk flare flush with adjacent finish grade. Place fertilizer prior to backfilling. Spread roots without tangling or turning toward surface, and carefully work backfill around roots by hand. Puddle with water until backfill layers are completely saturated. Plumb before backfilling, and maintain plumb while working backfill around roots and placing layers above roots. Tamp final layer of backfill. Remove injured roots by cutting cleanly; do not break. D. Form earth saucers around isolated plants of ample size to hold at least 5 gallons for trees and 2-1/2 gallons for shrubs. E. Mulching: Apply 3-inch average thickness of organic mulch extending 12 inches beyond edge of planting pit or trench. Do not place mulch within 3 inches of trunks or stems. F. Trunk Wrapping: Inspect tree trunks for injury, improper pruning, and insect infestation; take corrective measures required before wrapping. Wrap thin barked trees of 2-inch caliper and larger with trunk-wrap tape. Start at base of trunk and spiral cover trunk to height of first branches. Overlap wrap, exposing half the width, and securely attach without causing girdling. Do not wrap prior to October 1 and remove wrap by the following April 1. TREE AND SHRUB PRUNING A. Prune with clean cuts using sharp tools. Do not cut leaders. B. Remove only dead, dying, or broken branches unless directed otherwise by landscape architect. Do not prune for shape. C. When specifically directed by landscape architect, prune, thin, and shape trees and shrubs according to standard horticultural practice. Prune trees to retain required height and spread. Prune shrubs to retain natural character. The landscape contractor should anticipate the need to remove the lower limbs of canopy trees as directed by the landscape architect. D. Promptly treat accidental damage according to standard horticultural practice. TREE STABILIZATION A. Trunk Stabilization: Unless otherwise indicated, provide trunk stabilization as indicated on the Drawings and as follows: 5. Upright Staking and Tying: Stake trees as indicated on Drawings. Use length required to penetrate at least 18 inches below bottom of backfilled excavation and to extend one half of trunk height above grade. Set vertical stakes and space to avoid penetrating root balls or root masses. 6. Support trees with flexible ties. 7. PLANTING IN PLANTERS A. Place a layer of drainage gravel at least 4 inches thick in bottom of planters, cover with filter fabric, and fill with planter soil mix. Place soil in lightly compacted layers to an elevation of 1-1/2 inches below top of planter, allowing natural settlement. Water thoroughly and add soil to raise level to within one inch of top after settlement. GROUND COVER AND PERENNIAL PLANTING A. Set out and space ground cover and plants as indicated. Do not damage roots by separating individual plants. B. Dig holes large enough to allow spreading of roots and backfill with planting soil. C.
