Before planting, obtain Landscape Architect's acceptance of finish grading; restore planting areas if eroded or otherwise disturbed after finish grading. 3.2 EXCAVATION FOR TREES AND SHRUBS A. Planting Pits and Trenches: Excavate circular planting pits. 1. Excavate planting pits with sides sloping inward at a 45-degree angle. Excavations with vertical sides are unacceptable. Trim perimeter of bottom leaving center area of bottom raised slightly to support root ball and assist in drainage away from center. Do not further disturb base. Ensure that root ball will sit on undisturbed base soil to prevent settling. Scarify sides of planting pit smeared or smoothed during excavation. 2. Excavate approximately three times as wide as ball diameter. 3. Excavate at least 12 inches (300 mm) wider than root spread and deep enough to accommodate vertical roots for bare-root stock. 4. Do not excavate deeper than depth of the root ball, measured from the root flare to the bottom of the root ball. B. Backfill Soil: Subsoil and topsoil removed from excavations may be used as backfill soil unless otherwise indicated. 3.3 TREE, SHRUB, AND VINE PLANTING A. Inspection: At time of planting, verify that root flare is visible at top of root ball according to ANSI Z60.1. If root flare is not visible, remove soil in a level manner from the root ball to where the top-most root emerges from the trunk. After soil removal to expose the root flare, verify that root ball still meets size requirements. B. Roots: Remove stem girdling roots and kinked roots. Remove injured roots by cutting cleanly; do not break or tear. C. Set each plant plumb and in center of planting pit or trench with root flare 1 inch (25 mm) above adjacent finish grades. 1. Balled and Burlapped Stock: After placing some backfill around root ball to stabilize plant, carefully cut and remove burlap, rope, and wire baskets from tops of root balls and from sides, but do not remove from under root balls. Remove pallets, if any, before Received by DiMarco 02/23/2021 Park Grove – Cayuga Medical Center MEDICAL OFFICE BUILDING Cayuga Park, Ithaca, NY 14850 PLANTS 329300 - 6 setting.

Balled and Potted and Container-Grown Stock: Carefully remove root ball from container without damaging root ball or plant. 3. Fabric Bag-Grown Stock: Carefully remove root ball from fabric bag without damaging root ball or plant. Do not use planting stock if root ball is cracked or broken before or during planting operation. 4. Bare-Root Stock: Support stem of each plant and spread roots without tangling or turning toward surface. Plumb before backfilling and maintain plumb while working. Carefully work backfill around roots by hand. Bring roots into close contact with the soil. When planting pit is approximately one-half filled, water thoroughly before placing remainder of backfill. Repeat watering until no more water is absorbed. 5. Continue backfilling process. Water again after placing and tamping final layer of soil. D. Slopes: When planting on slopes, set the plant so the root flare on the uphill side is flush with the surrounding soil on the slope; the edge of the root ball on the downhill side will be above the surrounding soil. Apply enough soil to cover the downhill side of the root ball. 3.4 TREE, SHRUB, AND VINE PRUNING A. Prune, thin, and shape trees, shrubs, and vines according to standard professional horticultural and arboricultural practices. Unless otherwise indicated by Landscape Architect, do not cut tree leaders; remove only injured, dying, or dead branches from trees and shrubs; and prune to retain natural character. 3.5 GROUND COVER AND PLANT PLANTING A. Set out and space ground cover and plants other than trees, shrubs, and vines as indicated on Drawings in even rows with triangular spacing. B. Dig holes large enough to allow spreading of roots. C. Work soil around roots to eliminate air pockets and leave a slight saucer indentation around plants to hold water. D. Water thoroughly after planting, taking care not to cover plant crowns with wet soil. E. Protect plants from hot sun and wind; remove protection if plants show evidence of recovery from transplanting shock. 3.6 STREET TREE PLANTING A. Inspection: At time of planting, verify that root flare is visible at top of root ball according to ANSI Z60.1. If root flare is not visible, remove soil in a level manner from the root ball to where the top-most root emerges from the trunk. After soil removal to expose the root flare, verify that root ball still meets size requirements.

Remove injured roots by cutting cleanly; do not break. C. Balled and Burlapped Stock: Set each plant plumb and in center of planting pit or trench with root flare 2” below adjacent finish grades. 1. Backfill: Planting soil as indicated in soils plan. Following installation of structural soil, ensure that adequate depth is provided for installation of planting soil for street trees. 2. After placing some backfill around root ball to stabilize plant, carefully cut and remove burlap, rope, and wire baskets from tops of root balls and 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. 3. Backfill around root ball in 6” lifts, lightly compacting to settle soil and eliminate voids and air pockets. When planting pit is approximately one-half filled, water thoroughly and allow all water to percolate. Repeat watering until no more water is absorbed before placing remainder of backfill. 4. Continue backfilling process. Water again after placing and tamping final layer of soil. D. Post-planting inspection to be performed by Landscape Architect. 3.7 PLANTING AREA MULCHING A. Mulch backfilled surfaces of planting areas and other areas indicated. 1.
