Climate Change and Your Garden Checklist

Preparedness actions when there is too little water. 

  • Convert lawn to low-water plants
  • Add 2 to 3 inches of mulch to all planted areas
  • Add compost to all planted areas
  • Water all planted areas as low water
  • Space out watering days gradually to drive roots down deeper
  • Use web application to create accurate irrigation schedule:
    https://www.valleywaterscheduler.com/
  • Upgrade to a smart controller
  • Change out inefficient sprinkler nozzles for efficient ones
  • Find areas of the garden to hand water with recovered water from the house
  • Use How Much Water web app to determine how much
    water the plants need https://waterwonk.us/how-much/
  • Purchase hose-end flow meter to monitor amount of water being used
  • Harvest rainwater – see checklist for too much water
  • Water plants with water recovered from the house
  • Set up a greywater system. Laundry-to-landscape is the easiest and doesn’t require a permit
  • Order of water-source preference for irrigation: 1. Rainwater;
    2. Greywater; 3. Potable water

Preparedness actions when there is too much water.

  • Note where water flowed and collected during winter storms
  • Direct downspouts away from the foundation and into the garden
  • Build a rain garden
  • Sculpt the garden into berms and swales
  • Build a dry creek bed
  • Install French drains where needed (consult with a professional)
  • Install a dry well (at least 12 feet from foundation of house)
  • Install cisterns, tanks, or barrels to collect rainwater
  • Remove weed fabric (or don’t install it in the first place)
  • Look for areas to convert hardscaping to permeable materials
  • Implement erosion control measures on slopes
  • Hire arborist to prune trees to make them lighter and with open spaces for wind to pass through
