    • Landscape irrigation Terms & Equipment Plant: Japanese Barberry Term: Irrigation
    • Japanese Barberry
      • Shrub, deciduous
      • Hardiness Zones: 4a to 8a
      • Height: 3’ to 6’ by Spread : 4’ to 6’
      • Exposure: shade to full sun
      • Leaf Color: Green, Purple – Grown for Foliage not blooms
      • Has small red berries in fall
      • Grows very slowly
      • Looks like a red boxwood
      • Has small thorns
    • Irrigation
      • Supplying water to land through artificial means.
      • Two Types
        • Drip – applied to the soil
        • Sprinkler – applied over head
    • Drip Systems
      • Used for garden beds, individual plants
      • Impractical for turf.
      • Drip tubes or porous tubes
      • Tree Gators
      • May be mandated by code in water conservation areas
      • Two emitters
        • Pressure compensating – needed for rolling terrain
        • Non-compensating
      • Emitter spacing depends on soil types and root zone size
    • Sprinklers
      • Used for turf grass areas
      • Used for garden beds where obstructions do not block spray patters
      • Spray heads – steady flow
      • Impact or rotary heads – larger area
    • Comparison To the roots of plants Over top of plants Delivery Location tubing & drip emitters Spray or rotary heads Delivery Mechanism Low Pressure High Pressure Delivery Pressure Drip Sprinkler
    • Comparison Inexpensive Can’t see prob-lems til too late Expensive Easy to find problems Installation & Maintenance No run-off No evaporation Run-off Evaporation Problems Slow Gallons/hour Fast Gallons/minute Delivery Rate Drip Sprinkler
    • Sprinkler Heads:
      • Pop-up
        • Size depends on the plant height in the zone
      • Spray Nozzles
        • Color indicates distance of throw
      • VAN – Variable Angle Nozzle
    • Sprinkler Systems
      • Areas to be irrigated are divided into zones based on water flow rates
      • Each zone is controlled by a solenoid valve
      • Irrigation controller – computer that tells valves when to turn on and off
    • Today
      • Complete day 1 of irrigation packet
      • Watch video on planning irrigation
      • Go to flagpole garden
        • Measure & sketch the garden
      • Measure gallons per minute from the bib
