How Green Is Your Garden? A Sustainability Quiz

Your garden practices affect the larger landscape—neighborhood, meadows, deserts, forests, waters. Take the quiz, add 1 point per "yes," find your score meaning at bottom.

DESIGN

  1. Paving: Permeable paving (gravel, decomposed granite, pavers with spaces)?
  2. Irrigation: Drip system with automatic controller? Regularly reprogrammed for seasonal demands?
  3. Watering zones: Group plants by water needs? Major areas survive on rainfall after second season?
  4. Water features: Pondless waterfalls/small recirculating fountains, or dry creekbed/paving mimicking water, or no water features? Infiltration pit or rain garden to catch/filter rainwater?
  5. Trees for shade: Deciduous trees sited for summer cooling shade, winter sun?
  6. Materials/furnishings: Sustainably harvested woods (ipe, bamboo) or recycled (Trex)?

PLANTING

  1. Appropriate plants: Well-adapted to climate (natives/appropriate non-natives)? Locally grown? Disease-resistant varieties of fruit trees, roses, tomatoes?
  2. Lawns: Unthirsty grass (buffalo grass) or no lawn?
  3. Plants for wildlife: Feed/shelter birds, butterflies? Flowers attracting beneficial insects (ladybugs, lacewings)? Perennials (echinacea, lavender, penstemon, salvia) attracting pollinators (bees, hummingbirds)?

MAINTENANCE

  1. Composting: Regularly compost all green/brown waste (leaves, seedless weeds, clippings, spent flowers, vegetables)?
  2. Fertilizing: Leave grass clippings to refertilize turf? Use natural fertilizers (aged chicken manure, liquid fish emulsion) for veggies/annuals?
  3. Mulching: Regularly mulch with organic materials to suppress weeds, conserve water?
  4. Nontoxic controls: First try soft controls (water jets for aphids, corn gluten for weeds, handpicking/copper for snails)? Educate on pest/disease/weed products before use? Avoid garden chemicals before/during/after rains?
  5. Recycling: Recycle (not toss) brick, broken concrete, nursery containers? Properly dispose of chemicals via local agencies?
  6. Soils: Refresh beds each season by tilling in generous organic amendments (aged compost)?
  7. Tools: Use hoes, reel mowers, rakes instead of gas-powered tools causing dust, noise, air pollution?
  8. Watering: Water efficiently—no runoff/waste (slowly, deeply, infrequently, early morning/evening, never windy)? Irrigate established trees slowly/deeply with soaker hoses/deep-root irrigators in heat? Capture rainwater in barrels for later use?
  9. Weeding: Pull weeds before they set seed/spread? Ensure new plants aren't invasive in your area (English ivy, buddleja in NW; pampas grass, Scotch broom in CA; grasses, Kahili ginger in HI)?
