What are the primary sources of water pollution?
• Point Sources
– When you can point at a specific source (industrial, power plants…)
• Atmospheric Deposition
– From sky (fumes=pollution goes rain brings it )
• Non-Point Sources
– When you can’t point at the source, pollution comes from diverse sources (illegal dumping, stormwater runoff, soils-sediments)
![Page 11: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/11.jpg)
Impervious Surfaces
An impervious
surface does not
allow water to pass
through it.
Roads, roofs,
sidewalks and
driveways are
examples
![Page 12: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/12.jpg)

Pinellas County’s Urban Growth
More development = More areas of
impervious surface = More pollution!!
![Page 13: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/13.jpg)
Impervious surfaces
lead to storm drains
Contents go to a
wastewater
treatment plant
Contents get dumped into a
body of water such as a
stream, river, lake, gulf or
ocean

Plastic isn’t the only problem a) Nutrients – fertilizers, animal waste, etc
b) Organic debris (grass clippings, lawn
debris, leaves)
c) Petroleum products, oil, grease, etc
d) Soil and sediment from erosion
e) Toxic chemicals, pesticides, etc

Here’s What
We’ve Learned
Most pollution…
plastic, oil, chemicals,
pesticides, nutrients,
fertilizer or organic debris
on an impervious
surface ends up in a
body of water
The result is:
Non-point source
pollution

Florida Friendly Landscaping
9 Principles:
![Page 24: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/24.jpg)
Choose The Right Plant for the
Site Conditions
Plants suited to the specific site conditions
– sun, shade,
– soil pH, drainage,
– salt tolerance
reduces the need for water, fertilizer, pesticides and
pruning
![Page 25: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/25.jpg)
Right Plant, Right Place…
Happens when you closely match
the site conditions to
the needs of the plant
As a result, the plant will be healthier and
happier. And you will have FAR fewer
problems and FAR less maintenance and
use FAR less pesticides.

Integrated Pest Management (IPM)
IPM is a set of
tactics and
techniques to
prevent and
suppress pests.
Pesticides are only
one of the tools.
![Page 30: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/30.jpg)
IPM Tools & Techniques
1) Reduce availability of food, water
and shelter
2) Use plants resistant to pests
3) Biological control – use both natural
enemies & biological products
4) Cultural control – what most of this
presentation is about
5) Mechanical control
6) Sanitation
7) Chemical control – the last option

Proper Planting Hole
The planting hole is at least 1.5 times the diameter of the root ball.
This provides loose soil for the expansion of new roots.

Step 2: Add a Berm
Not using a berm allows
water to run off.
Keep water where it is
needed by using a berm.

Improper Mulching
Mulching in a volcano-like manner can:
–Rot the trunk
–Cut off oxygen to roots
–Keep vital irrigation and rain water out
–Keep roots too wet in poorly drained soils
–Cause stem girdling roots on some trees

Reduction cut
shortens the length of
a stem by pruning
back to a smaller
limb.
Removal cut prunes a
branch back to the
trunk or parent
branch.

Bad Practice – Don’t Top Trees!!!
- It doesn’t work
- It’s expensive
- It’s UG-LY!
- It’s dangerous
- It’s bad for the tree
- It makes you look bad
Hire an arborist!
![Page 64: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/64.jpg)
Objective: Avoid trimming that may
cause tree failure or property damage
• Codominant stems: stems of equal size originating from the same point on the tree
Hire a certified arborist!
• Included bark: bark pinched between two stems, indicating a weak union
![Page 65: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/65.jpg)
Bad Practice – Lion-Tail
• Foliage concentrated
at branch tips; inner
branches removed.
• More risk of storm
damage
• Hard to restore
Hire an arborist!!

Bad Practice – Crape Murder
Stop Crape Murder!!
Research says crapes
pruned hard (topped):
• Blooms less
• Blooms later
•Ruins natural form
•Causes permanent
damage and leads to
death

Branch bark ridge
Collar: swollen area at the base of
the branch where it joins the trunk.
This tissue is rich in energy
reserves and chemicals that hinder
the spread of decay. Good pruning
cuts avoid cutting into the collar.

Yellow fronds on palms are a symptom of a nutrient
deficiency. Removing them usually makes the problem
worse and limits diagnosis.
Pruning Palms
Over pruned!
![Page 74: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/74.jpg)
Pencil necking, caused by over pruning, will increase the chance that it will break in a storm, and will eventually lead to death of the palm.
The “hurricane cut” may actually reduce the protection for the palm.
Over grooming can kill palm trees
![Page 75: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/75.jpg)
The fronds protect the
core of the tree. If the
core is damaged the
tree dies.
Hurricane cutting is
illegal in Broward
County because it is
so harmful to palm
trees.
Do not hurricane cut palms!

Pruning Palms
9 3
- Don’t prune
palms needlessly
-Never cut off
green fronds.
- Never trim palms
above 9 to 3.
- Pruning reduces
the palms ability
to produce food
for itself.

Types of Grass
Zoysia
Less nitrogen needed;
does well in heat, but very
slow growing; not shade
tolerant; can get brown
patch;
mow height 1.5”- 2.5”
Bahia Grass
Most water-thrifty, needs
less fertilizer, but difficult
to mow; can get weedy,
prone to mole crickets;
mow height 3”- 4”
St. Augustine
Most common lawn grass: Shade-tolerant
varieties; Needs extra water; prone to
pests (chinch bugs), thatch; mow height
3.5”- 4” standard and 2”- 2.5” dwarf
Bermuda Grass
Good in full sun; drought and
salt tolerant; prone to pests and
disease; mow height 0.5” – 1.5”

Mower Blade Maintenance
91
• Dull blades tear instead of cut
• Sharp blades cut clean
• Torn blades invite disease
• Torn blades lose more
moisture
• Keep mower blades sharp!

Remove only 1/3 of the leaf blade at each mowing
Tip: Clippings don’t
cause thatch, over
watering and over
fertilization causes thatch

EXAMPLE:
Let St. Augustine reach
6 inches before
mowing, then cut 2
inches off top

Pests in the Landscape
• Improper landscape practices or wrong site conditions for a particular species
• Cultural practices (improper fertilization, irrigation, mowing) can contribute
• Simply treating the pest will not cure (find cause of pest problem)
• Overwatering can promote disease
• Stressed plants have less resistance to pests

Watering Your Lawn
The average Floridian uses
about 124 gallons of water each
day
Outdoor water use accounts for
50% of water used by
households
Florida consumes more fresh
water than any other state east
of the Mississippi River

But it can have a big effect on water use!
Irrigation may not be your job
![Page 120: Pinellas County Landscape BMP Certification Class1) Reduce availability of food, water and shelter 2) Use plants resistant to pests 3) Biological control – use both natural enemies](https://reader035.vdocuments.net/reader035/viewer/2022062602/5ed91d766714ca7f47692d51/html5/thumbnails/120.jpg)
Be A Water Saver
• Inspect your sprinkler system
• Repair any problems, adjust spray
heads and nozzles so you’re not
watering hard surfaces
•Adjust your timer seasonally!
• Water just before, or just after sunrise
• Make sure you have a working rain
sensor: Florida law requires it!
Clue: If it’s raining and the sprinkler
system is running, your customer
doesn’t have a rain sensor or it’s not
working

Frequency
is how often
you irrigate
a zone
Duration
is how long
the zone runs
Duration determines how
deep the water goes.
