Water Needs increase in Heat Islands Landscape plants in heat
islands require up to 50% more water than the same species in park
settings Landscape plants in heat islands require up to 50% more
water than the same species in park settings

Sustainable Landscapes Conserve Water Through: 1. Hydrozoning
2. Scheduling irrigations based on plant needs 3. Making sure
sprinklers/drip systems work properly 3. Making sure
sprinklers/drip systems work properly 4. Using mulch and soil
amendments effectively 4. Using mulch and soil amendments

Slide 14
Hydrozone : Place plants with similar water needs together and
irrigate them accordingly
Slide 15
Star Jasmine Less Drought Resistant than Cotoneaster
Slide 16
Drip Irrigate Trees, Shrubs, and Gardens to Reduce Soil
Evaporation and to Apply Water Directly into Root Zones
Slide 17

Steps 3 and 4: Add Drip Tube and Stake
Slide 20
Warm-Season Lawns (bermudagrasss) Use Less Water than
Cool-season lawns (tall fescue)
Slide 21
To prevent water waste and brown spots in turf and
groundcovers, repair leaks, low heads, broken sprinklers, unmatched
sprinklers and pressure and spacing problems
Slide 22
Use UC ANRs Lawn Watering Guide Based on Warm Season Kc =.6 and
Cool Season Kc =.8 and a Distribution Uniformity of 80%

(warm vs cool season turf) Determine type of lawn (warm vs cool
season turf) Conduct a Can Test to determine sprinkler system
output and distribution uniformity Conduct a Can Test to determine
sprinkler system output and distribution uniformity Determine how
long to irrigate (minutes per week) based on climatic chart
provided Determine how long to irrigate (minutes per week) based on
climatic chart provided Determine maximum amount of time to water
per event until runoff just begins Determine maximum amount of time
to water per event until runoff just begins

Water cycling may be necessary to avoid run- off. Divide the
total amount of water required per day into 2-4 cycles. Apply water
as close to initial event as possible before soil dries out.
Slide 32
Irrigate Deeply and Infrequently and Monitor Soil Moisture Soil

Other Methods to Conserve Water in the Landscape
Slide 34
Minimize the use of water to clean sidewalks and driveways
Slide 35
Remove weeds that compete with landscape plants for water
Slide 36
Irrigate Established Plants Deeply and Infrequently Avoid
watering every day Avoid watering every day Water a few inches
below the current root system during each watering to encourage
deep rooting Water a few inches below the current root system
