EXHIBIT C
PLANTING AND MAINTENANCE GUIDELINES
A. Planting
Site factors which influence long-term survivability should be considered: overhead and
underground utilities, sidewalks, sign conflicts, traffic visibility, light poles, right-of-way or site
improvements, size of planting space/site, etc.
All planting stock or replacement stock must be Florida Grade #1 or better.
All synthetic or non -biodegradable material such as nylon rope, synthetic wrap, treated burlap, etc.
must be removed from the root ball before planting. All biodegradable material should be removed
from the upper 1/3 of the root ball. Precautions should be taken to eliminate any material from
extending above the soil surface where it can act as a wick and dry the surrounding soil.
If trees are planted with wire baskets around the root ball, it is recommended that the top two tiers
of wire be cut and removed after the root ball is set in the planting hole.
The planting hole should be at least 3-5 times the diameter of the root ball (where possible) and
the same depth as the root ball.
Position the tree or palm in the center of the planting hole with the top of the root ball even with the
surrounding soil surface.
Backfill with soil from the planting site, if it is not contaminated. All large rocks should be removed.
When the hole is half full, slowly water to saturate the soil and remove air pockets, then continue to
fill the hole with soil. It is not recommended that large amounts of organic matter be incorporated
into the backfill. Rake the soil evenly around the entire planting area.
Water thoroughly to remove air pockets, secure the soil around the roots, and provide
nourishment.
B. Mulching
Mulch an area at least three times the diameter of the root ball to a depth of 2-4" with wood chips,
bark mulch, shredded mulch, leaves or pine needles. Keep the mulch several inches away from
the tree or palm trunk.
Replenish mulch as it decomposes maintaining a 2-4" layer over the life of the project.
C. Staking
Stake only if necessary; for example, if the tree or palm will not stand on its own due to potential
vandalism or strong winds.
Use flexible materials such as strapping or commercially available ties that give as the tree
diameter increases and as the tree moves. Biodegradable material is recommended.
Do not use wire even if the wire is inside rubber hosing.

Stakes and ties should remain on the trees no longer that one year to avoid girdling.
D. Pruning
At the time of planting, only dead, damaged, rubbing or cross braches or fronds should be
removed.
Remove sucker sprouts from the base of the tree after planting.
Corrective/structural pruning can begin approximately one year after planting. Do not remove more
than 1/3 of the live crown during one growing season.
E. Watering
Establish a regular watering schedule and follow it. Slow deep watering is recommended.
Additional water may be needed during hot or dry periods.
As tree or palm growth progresses, be sure to water outward (away from the trunk) to the
surrounding soil area. This will promote the outward growth and spread of roots.
Various species of trees or palms and/or soil types may require varied degrees of watering. Soil
moisture and tree health should be monitored and irrigation adjusted accordingly. Non -irrigated
sites need to be monitored more closely.
F. Fertilizing
Begin a fertilization program within the first year of planting. Broadcast fertilizing or fertilizer
plugs/stakes are recommended.
Fertilize lightly after the first year using a balanced fertilizer (rates should be based on the size of
the tree or palm and any special nutrient requirements).
If micronutrient deficiencies are suspected, have a soil test completed and supplement the
fertilization program accordingly.
