  8. 8. Functional Landscaped Beds <ul><li>Screen a view </li></ul><ul><li>Cover oddly-shaped areas difficult to mow or irrigate </li></ul><ul><li>Plant a shady area where turf won’t grow </li></ul><ul><li>Group plants for easy maintenance </li></ul><ul><li>Provide color, shade, or windbreak </li></ul>Periwinkle Annuals, perennials, ground covers, shrubs or trees in a mulched area, to:
  9. 9. Drought Tolerant Turf <ul><li>Select drought tolerant turf varieties </li></ul><ul><ul><li>When establishing a new lawn, sod requires less water than seeding </li></ul></ul><ul><li>Follow maintenance guidelines to promote drought tolerance </li></ul><ul><ul><li>During extreme drought, slower growth and browning are normal! Very little water is required to keep the turf alive and turf recovers quickly once irrigation is resumed. </li></ul></ul>
  10. 10. Selecting Drought Tolerant Turf <ul><li>Seashore Paspalum ‘SeaIsle </li></ul><ul><li>Excellent drought tolerance </li></ul><ul><li>Excellent salt tolerance </li></ul><ul><li>Disease and pest resistant </li></ul><ul><li>Tolerates flooding and some shade </li></ul><ul><li>Mow at 1.5 – 2 inches in height </li></ul><ul><li>Does require lot of mowing and fertilizing </li></ul>Seashore paspalum Paspalum vaginatum (Swartz)
  11. 11. Selecting Drought Tolerant Turf Bahiagrass Paspalum notatum <ul><li>Bahiagrass Argentine </li></ul><ul><ul><li>Good cold and drought tolerance </li></ul></ul><ul><ul><li>Coarse, dense growth </li></ul></ul><ul><ul><li>Wear tolerant </li></ul></ul><ul><ul><li>Dormant in winter </li></ul></ul><ul><ul><li>Poor salt and shade tolerance </li></ul></ul><ul><ul><li>Mow at 3-4 inches </li></ul></ul>
  12. 12. Maintenance Guidelines for Drought Tolerant Turfgrass <ul><li>Never mow grass that needs water </li></ul><ul><li>Never mow wet grass </li></ul><ul><li>Keep blade sharp </li></ul><ul><ul><li>Clean cuts heal quickly and reduce water loss </li></ul></ul><ul><li>Mow lawn at the </li></ul><ul><li>highest setting </li></ul><ul><ul><li>Taller grass has deeper, more extensive roots </li></ul></ul>
  13. 13. Turfgrass Maintenance <ul><li>Fertilize conservatively </li></ul><ul><ul><li>Rapid growth promotes thatch build-up </li></ul></ul><ul><ul><li>Refer to UF/IFAS guidelines </li></ul></ul><ul><li>Remove thatch </li></ul><ul><ul><li>Thatch restricts water movement </li></ul></ul><ul><ul><li>Use a stiff rake or coring tool to aerate the soil </li></ul></ul><ul><ul><li>Thatch </li></ul></ul>
  14. 14. Landscape Maintenance <ul><li>2-3 inches of mulch in plant beds </li></ul><ul><ul><li>Improves water infiltration </li></ul></ul><ul><ul><li>Reduces storm water runoff </li></ul></ul><ul><ul><li>Reduces evaporation </li></ul></ul><ul><ul><li>Prevents erosion </li></ul></ul><ul><ul><li>Controls weeds </li></ul></ul><ul><li>Minimize pruning </li></ul>
  15. 15. When Do I Water? <ul><li>Early morning or evening </li></ul><ul><ul><li>Temperature is cool and wind is calm </li></ul></ul><ul><ul><li>40% - 60% of water applied evaporates in the afternoon sun! </li></ul></ul><ul><li>SWFWMD mandates: </li></ul>No watering between 10 AM and 4 PM Year - round!
  16. 16. How Much? <ul><li>Apply ½ to ¾ inch water per application </li></ul><ul><li>Soak soil thoroughly to promote a deeper, more drought tolerant root system </li></ul>Efficient watering wets only the root zone.
  17. 17. Measure It <ul><li>Use a rain gauge, or… </li></ul><ul><li>Place cans of equal diameter in random places underneath the sprinkler’s spray pattern </li></ul><ul><li>Measure the depth of water in each can </li></ul><ul><li>Add depth measurements & divide by the number of cans </li></ul>Determine the length of time it takes for your sprinkler system to deliver ¾ inch water.
  18. 18. How Often? <ul><li>Water “as needed,” not routinely! </li></ul><ul><li>Less frequently in the fall and winter </li></ul><ul><li>Check with CCU or SWFWMD about water restrictions during drought </li></ul>Typically, Florida’s rainy season is June - September.
  19. 19. Watering Tips <ul><li>Learn to recognize when plants need water </li></ul><ul><li>In the heat of midday, some plants wilt. No amount of water will change this. If the plant is still wilted by evening, water it then. </li></ul>Wilting azalea
  20. 20. Water “As Needed” Folded leaflets, a blue color, and footprints that remain on the lawn are indications of a lawn that needs water.
  21. 21. Too much of a good thing? <ul><li>Over watering occurs when water is applied too frequently or in excessive amounts </li></ul><ul><ul><li>Encourages growth of fungi and bacteria </li></ul></ul><ul><ul><li>Promotes a shallow root system </li></ul></ul><ul><ul><li>Reduces oxygen to the roots, causing stress </li></ul></ul><ul><ul><li>Encourages weed growth </li></ul></ul>Pennywort is a good indication of an over watered lawn.
  22. 22. Irrigation Systems <ul><li>Calibrate the sprinkler system </li></ul><ul><li>Install a rain shut-off device** </li></ul><ul><li>Have your sprinkler system “tuned up” yearly </li></ul><ul><li>Replace worn hose and faucet washers </li></ul>Rain Shut-off Device
  23. 23. Efficient Irrigation <ul><li>Separate lawn zones from landscape zones </li></ul><ul><li>Convert landscape beds to drip or low volume irrigation </li></ul><ul><li>Divert sprinklers to avoid spraying water on sidewalks and streets </li></ul>
  24. 24. Low Volume Sprinklers Micro-jet sprinkler Drip emitters Micro-irrigation can improve watering efficiency.
  25. 25. Tips on Conserving Water <ul><li>Use recycled or gray water to irrigate </li></ul><ul><ul><li>From showers or washing machines, but not toilets </li></ul></ul><ul><li>Direct downspouts toward beds or lawn </li></ul><ul><li>Cover pools and hot tubs to prevent evaporation </li></ul>
  26. 26. Rain Barrels <ul><li>Collect and harvest rain water for irrigation purposes </li></ul><ul><li>Rainwater runs off roof into the barrel from the downspout </li></ul><ul><li>A screen fastened over the inlet prevents leaves or insects from entering </li></ul>
