Only 1% of the earths water is fresh water available for drinking, bathing, and cooking. Only 1% of the earths water is fresh water available for drinking, bathing, and cooking.

6. Facts About Water We only need about 15 gallons of water per day per person for drinking, bathing, and cooking, yet per capita water consumption in the U.S. exceeds 100 gallons/day. We only need about 15 gallons of water per day per person for drinking, bathing, and cooking, yet per capita water consumption in the U.S. exceeds 100 gallons/day. If every household in the U.S. saved just If every household in the U.S. saved just 1 gallon of water a day, we would save 120 1 gallon of water a day, we would save 120 million gallons of water per day, enough million gallons of water per day, enough water for a city the size of Jacksonville, FL. water for a city the size of Jacksonville, FL.

7. Global Demand for fresh water will double every 20 years Worldwide

Challenge – Serving GAs Growing Urban Population GAs Population 2001 – 8.4 million 2005 – 9.1 million 2010 – 9.9 million 2015 – 10.8 million Over half of Georgias population resides in 12 counties. Two-thirds of Georgias population resides in 26 of its 159 counties. 21 counties have populations over 100,000.

9. Average residential water use increases 30% - 50% during the summer months when citizens turn on their outdoor irrigation systems

10. One portable lawn sprinkler operating for 1 hour uses 360 gallons of water This is equivalent to: This is equivalent to: 72 flushes of the toilet 9 full loads of laundry 14 five-minute showers 26 runs of the dishwasher

No one may water on Fridays.

13. Goal of Water Wise Landscapes To reduce and minimize the size of the area irrigated and the frequency of irrigation

19. Seven Steps of Xeriscape

22. Divide the Landscape into Three Water-use Zones High Water-use Zones (Oasis Zones) High Water-use Zones (Oasis Zones) Moderate Water-use Zones (Transition Zones) Moderate Water-use Zones (Transition Zones) Low Water-use Zones (Xeric Zones) Low Water-use Zones (Xeric Zones)

23. High Water-use Zone (Oasis Zone) Small high-impact or high visibility area of the landscape where plants are provided their optimum water requirement at all time Entrance to the home or business

24. Moderate Water-use Zone (Transition Zone) Plants are watered during establishment. Once established, they are watered only when they show signs of water stress. Azaleas, dogwoods, redbuds, herbaceous perennials

25. Low Water-use Zone (Xeric Zone) Low Water-use Zone (Xeric Zone) Once established, plants are provided no supplemental irrigation, except during periods of extreme drought Juniper Crape Myrtle Yaupon Holly Oaks Native Areas

26. 10% of the landscape is irrigated regularly 30% of the landscape is irrigated on demand 60% of the landscape is not irrigated

27. Shade helps reduce water loss in the landscape

35. Seven Steps of Xeriscape

36. Dont Guess…Soil Test!

38. Use only decomposed organic material (right) as a soil amendment

39. More plants are killed in Georgia from over-watering than from drought

40. Plant on raised beds Plant on raised beds Deep cultivation Deep cultivation Install sub-surface drainage Install sub-surface drainage Select appropriate plants Select appropriate plants Possible Solutions to Poorly-drained Soils

41. Seven Steps of Xeriscape

42. Select Plants Adapted to the Site and the Stresses of the Environment Drought tolerance is important, but also consider potential insect and disease problems, sunlight and soil requirements.

53. Seven Steps of Xeriscape

54. Use Turfgrass for a Purpose Aesthetic Value (Welcome Mat) Aesthetic Value (Welcome Mat) Recreational Surface Recreational Surface Erosion Control Erosion Control Minimize the amount of irrigated turfgrass

55. Avoid Using Irrigated Turfgrass Just to Fill Space

57. Seven Steps of Xeriscape

58. For most efficient use of water, irrigate at night to avoid evaporative loss of water. Avoid light, frequent irrigation because it encourages shallow rooting and increases water demand of the plant.

59. Target irrigation to plants that show signs of stress Gray/green Color Gray/green Color Wilting Wilting Dying Branches Dying Branches Use a hand-held hose with water nozzle or a sprinkler can to target irrigation to plants that need water.

60. Drip Irrigation Uses 30% to 50% less water than sprinkler irrigation Avoids spraying foliage so diseases are less likely to occur No spray drift Only need to water 25% of the root area

61. Seven Steps of Xeriscape

62. Benefits of Mulch Prevents evaporative water loss from the soil Prevents evaporative water loss from the soil Prevents soil-borne diseases Prevents soil-borne diseases Insulates the roots of plants from extreme heat and cold Insulates the roots of plants from extreme heat and cold Reduces weed competition Reduces weed competition

63. Best Mulch OrganicFine-texturedNon-matting

64. How Much Mulch To Apply? 3 to 5 inches deep is sufficient 1 bale of pine straw covers approximately 50 sq. ft.

66. Newspaper placed under mulch, 2- to 3-sheets thick, helps provide an added barrier to moisture loss.

67. Seven Steps of Xeriscape

68. Avoid Frequent Spurts of Vegetative Growth Brought on by: Fertilization Fertilization Pruning Pruning Irrigation Irrigation

69. Fertilization Target fertilization to plants that need it. Established trees and shrubs may not need to be fertilized annually. Target fertilization to plants that need it. Established trees and shrubs may not need to be fertilized annually. Use slow-release forms of nitrogen (Urea formaldehyde, IBDU, Sulfur-coated urea) Use slow-release forms of nitrogen (Urea formaldehyde, IBDU, Sulfur-coated urea) Use low rates of fertilizer. Use low rates of fertilizer. Limit fertilization during dry periods. Limit fertilization during dry periods.

70. Prune by selective thinning instead of shearing

75. Try these 5 to help them thrive! 1. Water only once a week, in the absence of rain. 2. Soak, don't sprinkle. 3. Don't water in the heat of the day. 4. Turn off sprinkler systems when it rains. 5. Mulch!

77. Make Every Drop Count !
