spread a minimum of 2" of compost (6.3 cub. yds./1000 sq. ft.) over all lawn
areas and plant beds. Large open mulch areas do not require compost.
E.
Rototill pH adjustment materials into the top 4" of soil.
F.
Fine grade rototilled areas to smooth, even surface with loose, uniformly fine
texture. Roll, rake and drag areas, remove ridges and fill depressions with soil
as required to meet finish grades. In areas to be sodded, allow for sod thickness,
providing a sod finish grade 1" below adjacent pavement or curbs.
G.
Moisten prepared areas before planting if soil is dry. Water thoroughly and allow
surface moisture to dry before planting lawns. Do not create a muddy soil
condition.
H.
Restore lawn areas to specified condition if eroded or otherwise disturbed after
fine grading and prior to planting.
LAYOUT:
A.
3.4
Two (2) weeks prior to planting operations, test existing soil for pH and submit
report from the University of Florida Extension (IFAS) Soil Testing Laboratory.
Collect soil samples in accordance with recommendations of the Laboratory. A
soil test kit may be obtained from the County Extension Service.
Lay out individual tree and shrub locations and areas for multiple plantings.
Stake locations and outline areas and secure approval before start of planting
work. Make minor adjustments as may be requested.
PLANTING TREES, SHRUBS AND GROUNDCOVERS:
A.
Perform all work in strict accordance with sound horticultural practice.
B.
Remove existing sod, roots, limerock, concrete, and other construction debris
from plant pits. Replace with topsoil.

C.
Place plants where shown and as detailed. After pits are excavated to
dimensions shown, remove containers and set plants plumb in center of pits. Set
the top of the root ball level with or slightly above the top of soil and orient plant
to present its best appearance. If the plant is balled and burlapped, remove
twine, loosen burlap at the top of the ball and roll back to expose the entire side
of the ball. Cut off and remove loose burlap. If the plant ball is wrapped with
plastic or other non-bio-degradable fabric, remove wrap totally from the ball.
Back fill with soil in 12 inch layers. Water in and compact each layer to eliminate
voids.
D.
Place temporary plant saucers around all trees and where directed. Immediately
apply at least 2" of water. After planting, remove excess soil and rake plant beds
to a smooth even surface conforming to required finish grades.
E.
Fertilization:
1.
2.
3.5
After shrubs and groundcovers are installed, apply 1/2 lb. of 16-4-8
fertilizer per 100 sq. ft. of shrub and ground cover bed areas.
After trees are installed, place fertilizer tablets on the soil surface evenly
around the outside edge of the rootballs. Place tablets at a rate of 1
tablet for each foot of tree height.
G.
Inspection of Fertilizer Application: Schedule with the Landscape Architect an
inspection after completion of the fertilizer application and obtain approval before
mulching. After approval, incorporate fertilizer into top 2 inches of soil.
H.
Pruning: Prune plants in accordance with standard horticulture practice. Prune
to remove suckers, dead, injured or diseased wood, and to achieve a uniform
shape natural to each species. Remove Lower branches of all trees to achieve a
minimum 5' clear trunk unless otherwise specified. Required plant sizes are after
pruning. Replace excessively pruned or misformed plants. Do not cut tree
leaders.
I.
Staking: Stake and guy trees as shown only when required to maintain them in a
vertical alignment. Set tree stakes vertical. Support trees with 2 strands of wire
encased in hose sections at contact points with tree trunk and twist securely. For
multi-trunked trees, use 2-3 guys securely attached to 2" x 4" x 24" stakes driven
to grade.
J.
Mulching: Apply 3 inches of mulch to all plant beds. Around each tree in lawn
areas, apply mulch 3" deep in a circle the diameter of the tree pit. Pull mulch at
least 4 inches from tree and shrub trunks. Rake to neat finished appearance.
Top of mulch to be 1" below adjacent lawn or pavement.
SODDING:
A.
Lay sod within 36 hours of stripping at farm.
B.
Lay sod in straight (not curved) parallel rows to form a solid mass with tightly
fitted joints, without overlap. Stagger strips to offset joints. Work topsoil into
minor cracks.
C.
On 4:1 slopes or greater, lay sod with long dimension of pads parallel to contours
and stake sod as necessary to stabilize sod. Avoid continuous seal along water
flow in swales. Drive stakes flush with top of sod.
D.
Roll entire sodded area with a 200 lb. roller.

Water sod immediately after rolling; thereafter water sufficiently to keep soil moist
to a depth of 4" until established.
F.
Where seeded areas meet sod, transition level of soil to cover sod root zone.
RECONDITIONING LAWN:
A.
Recondition existing lawn areas damaged by Contractor's operations, and where
minor grading is required within construction limits.
B.
Remove dead, and extensively damaged areas larger than 1 sq. foot. Remove
construction debris and topsoil containing foreign materials from construction
operations. Provide new soil to fill low spots and to meet new finished grades.
C.
Sod the prepared areas with the same grass species as the adjacent lawn.
D.
Where substantial lawn remains, but is thin (bare area greater than 2 inches
square), mow, rake, aerate compacted soil, remove extensive weeds, seed and
