  • 25. 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
  • 26. Some General Rules for Gardens and Landscapes
    An energy-intensive landscape
    A low-energy-use landscape
  • 27. If your practices and purchases use fossil fuels, consider using alternative methods
    Transportation
    Manufacture
    Materials
    Lifetime of Use
    Direct Fuel Use
  • 28. 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
  • 29. 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

  • 30. 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
  • 31. 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
  • 32. Build a Rain Garden

  • 33. 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

    http://extension.oregonstate.edu/yamhill/eco-gardening/native-plant-gardening
  • 34. Think Local, Think Wildlife
    Plant a Native Plant Garden--Reduce erosion, conserve water, encourage wildlife, lower maintenance
  • 35. 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
  • 36. 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
  • 37. Grow Your Own
    Know your food
    Save transportation costs
    Create family and community activities
    Live with the seasons
    http://extension.oregonstate.edu/gardening/
  • 38. 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”
  • 39. 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
  • 40. Turf Replacement Strategies
    Plants
    Permeable surfaces
  • 41. 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
  • 42. 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
  • 43. 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
  • 44. 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
  • 45. Sustainability Checkup
    Water Efficiency, Water Runoff
    Mulch, Fertilizer
    Recycle
    Wildlife
    Yard Pest Control
    Right Plant Right Place
    Presence/Control of Invasives
    Streams – Special Care
  • 46. Recognize and Create Sustainable Landscapes
    A mix of plants and plant communities encourages a diversity of plants and animals in a typical landscape
  • 47. 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.
