C. Measurements: Measure according to ANSI Z60.1. Do not prune to obtain required sizes.
1. Trees and Shrubs: Measure with branches and trunks or canes in their normal position.
Take height measurements from or near the top of the root flare for field-grown stock and
container-grown stock. Measure main body of tree or shrub for height and spread; do not
measure branches or roots tip to tip. Take caliper measurements 6 inches above the root

D. Product Data: For each type of product.
1. Plant Materials: Include quantities, sizes,quality, and sources for plant materials.
2. Plant Photographs: Include color photographs in digital format of each required species
and size of plant material as it will be furnished to Project. Take photographs from an
angle depicting true size and condition of the typical plant to be furnished. Include a scale
rod or other measuring device in each photograph. For species where more than 20 plants
are required, include a minimum of three photographs showing the average plant,the best
quality plant, and the worst quality plant to be furnished. Identify each photograph with
the full scientific name of the plant,plant size, and name of the growing nursery.
E. Plant Material Observation: Landscape Architect may observe plant material either at place of
growth or at site before planting for compliance with requirements for genus, species, variety,
cultivar, size and quality. Landscape Architect may also observe trees and shrubs further for
size and condition of balls and root systems, pests, disease symptoms, injuries, and latent
defects and may reject unsatisfactory or defective material at any time during progress of work.
Remove rejected trees or shrubs immediately from Project site.
1. Notify Landscape Architect of sources of planting materials seven days in advance of
delivery to site.

C. 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.
D. Trunk Stabilization by Upright Staking and Tying (Deciduous Trees): Install trunk stabilization
as follows unless otherwise indicated:
1. Upright Staking and Tying: Unless indicated otherwise by Landscape Architect, stake
trees of 2- through 5-inch caliper. Stake trees of less than 2-inch caliper only as required
to prevent wind tip out. Use a minimum of two stakes of length required to penetrate at
least 18 inches below bottom of backfilled excavation and to extend at least 72 inches
above grade. Set vertical stakes and space to avoid penetrating root balls or root masses.
2. Support trees with two strands of tie wire, connected to the brass grommets of tree-tie
webbing at contact points with tree trunk. Allow enough slack to avoid rigid restraint of
tree.
E. Trunk Stabilization by Staking and Guying (Coniferous Trees): Install trunk stabilization as
follows unless otherwise indicated on Drawings. Stake and guy trees more than 14 feet in height
and more than 3 inches in caliper unless otherwise indicated.
1. Site-Fabricated, Staking-and-Guying Method: Install no fewer than three guys spaced
equally around tree.
a. Securely attach guys to stakes 30 inches long, driven to grade. Adjust spacing to
avoid penetrating root balls or root masses. Provide turnbuckle for each guy wire
and tighten securely.
b. For trees more than 6 inches in caliper, anchor guys to wood deadmen buried at
least 36 inches below grade. Provide turnbuckle for each guy wire and tighten
securely.
c. Support trees with guy cable or multiple strands of tie wire, connected to the brass
grommets of tree-tie webbing at contact points with tree trunk and reaching to
turnbuckle.Allow enough slack to avoid rigid restraint of tree.
F. Steel Edging: Install steel edging where indicated according to manufacturer's written
instructions. Anchor with steel stakes spaced approximately 30 inches apart, driven below top
elevation of edging.
G. Install weed-control barriers before mulching according to manufacturer's written instructions.
Completely cover area to be mulched, overlapping edges a minimum of 6 inches and secure
seams with galvanized pins.
H. Mulching:
1. Trees in Turf Areas: Organic mulch ring of 3-inch thickness,with 24-inch radius.
2. Planting Areas: 3-inch thickness of organic mulch extending 12 inches beyond individual
planting pit or trench and over whole surface of planting area.
