  • 1. Lawn Maintenance
  • 2. What is the best grass for:
    • Shade?
    • Summer sports fields?
    • A fine looking lawn?
    • A quick green-up of a lawn?
    • A year round easy care lawn?
  • 3. Aeration
    • Lawn aeration involves the removal of small soil plugs or cores out of the lawn

  • 4. Aerators
    • Self-propelled
    • Towed
    • Manual
  • 5. Aeration
    • Grass recovers very quickly & then grows better
    • Increases oxygen availability to roots
    • Reduces compaction – roots can expand
    • Lets soil take up water better
  • 6. Aeration Video
    • Aeration Video
  • 7. Lawn Maintenance
    • Mowing
      • Mow at correct height for the grass
    • Fertilizing
      • Schedule depends on grass, soil texture & soil test result
    • Liming
      • Do a pH test to determine if it is required. Apply according to results.
    • Weeding
      • How many weeds are you willing to tolerate
    • Aerating
      • Not required often
    Decide how “organic” you want to be
  • 8. Mowing Height & Frequency
    • Never remove more than 1/3 of the grass length in a single mowing.
    • Longer grass can handle stress better than short grass
    • Longer grass outcompetes weeds
    • Leave longer during hot midsummer
    • Okay to cut shorter spring and fall
    • Alter the mowing path
  • 9. Mowers
    • Rotary
    • Reel
  • 10. Fertilization
    • Soil test first!!!
    • Never fertilize dormant grass
    • Feeding the roots – not the blades
    • Soil texture
      • sandy soils need most, Loamy soils need least
    • Grass species
      • Vary in their fertilizer needs
    • Organic option
      • Urea
      • Compost
    • Use high nitrogen, low phosphorus, medium potassium
      • 20-4-8
    • Note: Changes coming due to Chesapeake Bay Legislation
  • 11. Fertilizer
    • Cool Season
      • 1 lb in Sept
      • 1 lb in Oct
      • 1 lb in Nov
      • ½ lb in May
    • Warm Season
      • 1 lb in April
      • 1 lb in May
      • 1 lb in June
      • 1 lb in July/Aug
    Never apply more than 1 lb of N per 1000 sq ft .
  • 12. Lawn fertilizer
    • Follow directions on the bag
    • Add 1 lb N for 1000sq ft
    • Fertilizing a 2000 sq ft area
    • Our fertilizer mix is 28 – 3 – 3
    • ? Lbs of fertilizer
  • 13. Soil pH
    • Grasses favor high pH (alkaline soil)
    • Trees and forests leave low pH soil (acidic)
    • Virginia has a limestone rock base that results in acidic soils
    • Poor grass growth in low pH soil
    • Lots of moss in low pH (acidic) soil
  • 14. Lime
    • Calcium hydroxide: Ca(OH)2.
    • It is a white powder
    • Also called slaked lime , hydrated lime
    • A lot of new forms available that are easier to spread
    • Increases the pH of soil –
      • Makes them “sweeter” or more basic
    • Takes several years to work
  • 15. Weeds
    • Broadleaf weeds – Early spring – fall problem
      • Dandelion
      • Ground Ivy
      • Plantain
    • Grassy weeds – Hot summer problem
      • Bermuda grass
      • Crab grass
      • Annual Bluegrass
  • 16. Herbicides
    • Pre-emergence – prevents germination.
      • Apply in the early spring
      • Don’t apply before seeding
    • Post emergence – kills growing weeds
      • Broad leaf – only kills weeds
      • Broad spectrum – kills all plants
  • 17. Grass ID
    • Use the key to identify the grasses from the turf areas:
    • http://www.ipm.ucdavis.edu/TOOLS/TURF/TURFSPECIES/index.html
    • Tall Fescue
    • Kentucky Bluegrass
    • Perennial Ryegrass
