    • What gardeners can do!
      Reduce use of fossil fuels
      Recycle and compost
      Limit consumption
      Use common sense
      Protect the soil
      Reduce water use
      Work with nature
      Create communities of gardeners
    • Some General Rules for Gardens and Landscapes
      An energy-intensive landscape
      A low-energy-use landscape
    • If your practices and purchases use fossil fuels, consider using alternative methods
      Transportation
      Manufacture
      Materials
      Lifetime of Use
      Direct Fuel Use
    • Use the Power of the Sun
      Plant trees—they provide shade and moderate temperatures
      Deciduous trees on the south and west sides of house provide cooling influence in summer and let heat through in winter
      Use solar lighting if practical
      Shrubs, lawns, and other vegetation also cools, shades, and protects from wind
    • Go WaterWise
      Saves water for drinking, agriculture, or wildlife
      Creates beautiful landscapes
      Uses fewer chemicals because plants are better adapted
      Less water means less expended energy for water storage, delivery, and infrastructure

    • For WaterWise Plants, Choose:
      Plants from Mediterranean regions of the world, including California
      US prairie natives like sunflower
      Pacific Northwest native plants
      Grevillia rosemarifolia
      California fuchsia
      Cistus
      sunflower
    • Use Native Plants
      Native plants are already adapted to our climate
      Many different choices are available
      Most support local birds, butterflies and other wildlife
      Mock orange
      Wild strawberrry
      Ceanothus
    • Build a Rain Garden

    • Think Local
      Plants & seeds grown locally
      Native plants grown locally
      Local products, local sources
      Nurture native wildlife
      Control invasive plants and animals in the garden
      Iris tenax, a local native plant

    • Think Local, Think Wildlife
      Plant a Native Plant Garden--Reduce erosion, conserve water, encourage wildlife, lower maintenance
    • Reduce, Reuse, Recycle . . . .
      Buy used and/or buy sturdy, organize swaps or trades
      Save seeds
      Share resources with neighbors
      Compost at home or use leaves as mulch
      Use manual methods when you can
    • Learn from Nature
      In a natural forest, no one rakes up the leaves, and plants still grow and flourish
      Mimic nature by “composting in place”
      This practice reduces the need for adding fertilizers and mulch, saving money and energy
    • Grow Your Own
      Know your food
      Save transportation costs
      Create family and community activities
      Live with the seasons
      http://extension.oregonstate.edu/gardening/
    • Work Together for Greater Impact
      Save resources through sharing tools, equipment, plants, and garden space
      Create a community garden
      Help each other understand how our actions affect the world’s ecosystems and climate
      Create a new “look” for your community, maybe not so “tidy”
    • A Special Word About Lawns
      Leave grass clippings on the lawn to reduce or eliminate fertilizer – “Grasscycling”
      Use manual equipment when this is practical, with electric-powered being the next choice
      Once established, let the lawn evolve on its own –perfect turf in Oregon and Washington is a rarity
      Limit chemical use and seek alternatives to chemicals
    • Turf Replacement Strategies
      Plants
      Permeable surfaces
    • Be Creative: Use your garden to reduce overall energy use
      Use a clothes line
      Build arbors and pergolas for additional shade & wind breaks
      Create wind breaks with evergreen shrubs
    • Go Easy on the Chemical Inputs
      Use alternatives to herbicides such as hand weeding
      Stop and Think: Is there a better way?
      Nurture Your Soil—it will reward you in return
      Be tolerant of imperfection and respect natural processes
      If needed, consider using natural fertilizers like cottonseed meal or fish emulsion fertilizer
    • Support Pollinators & Other Beneficial Creatures
      Beneficial organisms include bees, butterflies, birds, insects, reptiles & amphibians
      Encourage garden biodiversity through care of the soil and limiting chemical inputs
    • Take the Landscape Sustainability Checkup
      Landscape Sustainability Checkup
      Is your yard ready to be an
      “Oregon Sustainable Landscape”?
      • Score at least 50 on the checklist to find out.
      http://extension.oregonstate.edu/douglas/sites/default/files/documents/hort/lscheckup.pdf
    • Sustainability Checkup
      Water Efficiency, Water Runoff
      Mulch, Fertilizer
      Recycle
      Wildlife
      Yard Pest Control
      Right Plant Right Place
      Presence/Control of Invasives
      Streams – Special Care
    • Recognize and Create Sustainable Landscapes
      A mix of plants and plant communities encourages a diversity of plants and animals in a typical landscape
    • What we do in our gardens affects people and ecosystems elsewhere, from our energy use, to what runs off with rainwater or escapes in the air. We cannot draw a bubble around our homes and gardens and live in isolation—it just doesn’t work that way.
