EXHIBIT A
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,
