5 13 establishing lawns

  1. 1. Establishing Turfgrass
  2. 2. Seeding Lawn • Establishing Lawn from Seed Video:
  3. 3. Soil Preparation • Best success when seeding bare ground • Use a tiller to prepare the seed bed • Remove sticks, rocks, clumps of old grass • Test the pH and the soil fertility • Use a fertilizer with high phosphorus numbers to build root growth
  4. 4. Rototiller • Front-tine – smaller & lighter, bounce a lot when trying to break new soil – work better for re-tilling existing plots • Rear-tine – bigger & stronger work best for preparing unused areas
  5. 5. Seeding • Most economical – Grass seed $15 - 20 for enough for 2,500 sq feet – Seed specific cultivars or blends – Seeds develop into the area where they will grow
  6. 6. Seeding Rates Species Seeds per pound Pounds/ 1000 sq ft Cost/pound Kentucky Bluegrass 1-2 million 1 – 3 $3 – 4 Bulk Tall Fescue 170,000 – 220,000 4 – 8 $1 Bulk Red Fescue 350,000 – 600,000 3 - 5 $1.75 Bulk Perennial Ryegrass 250,000 6 - 8 $1.25 Bulk
  7. 7. Seeding and fertilization pattern • Divide the amount of seed in half and sow half in each direction. • Remember to close the spreader when changing directions
  8. 8. Lime • Grass grows best at pH levels of 6.5 to 7 • Liming rates for 1000 sq ft Soil Texture Sandy Loam Clay pH 4 90 172 217 pH 5 67 127 150 pH 6 20 35 60 pH 7 None None None
  9. 9. Establishing Turf by Seed • Germination Rates: – Fast – Perennial Ryegrass – Medium – Fescue – Slow – Bluegrass & Bermuda Grass • Sow – 15 seeds/sq inch – Use rates recommended on the bag
  10. 10. Water • Water frequently with small amounts • Keep the soil surface moist • Don’t water so much as to create run-off
  11. 11. Seed types • Turfgrass blends – Different cultivars of the same species • Turfgrass mixture – Combination of two or more species – Examples: • Shade mix • High traffic mix
  12. 12. Grass seed label
  13. 13. Seed Labeling • Have information about the quality of the seed – Seed purity - % of identified species – Seed viability - % of seed that will germinate • Seeding rates – Different seeds have different weights and seeding rates – Also information on spreader settings – Want ~15 seeds per sq. inch.
  14. 14. Lawn Renovation • Kill everything and start-over • Kill existing grass with glyphosate (Round- up) • Allow 3 weeks to die completely • Cut to ½” height • Dethatch • Reseed
  15. 15. Overseeding • Add new seed to existing lawn • Good for bare spots or to improve lawn traits • Best in September • Cut grass short (1”) • Remove clippings & thatch • Reseed • May need to add compost or topsoil
  16. 16. Bermuda GrassBermuda Grass
  17. 17. Sod • Sod or turf is grass and the part of the soil beneath it held together by the roots, or a piece of this material.
  18. 18. Installing Sod Movie
  19. 19. Sod Farm • Grown on specialty farms & harvested by specialty equipment • Usually has 2-3 day life from harvest - can be longer if protected from heat or drying.
  20. 20. Sod Cost • Costs about $.20 - .30/sq ft if you are going to do it yourself – Very small lawn - 2000sq ft = $400 - 600 • Contractor will charge $.50/sq foot - not including soil prep • Sod costs 20X more than seed • Sod costs 10X more than sprigs
  21. 21. Quiz tomorrow • Review • Best grass for shade? • Best grass for quick greening? • Best grass for drought tolerance? • Best looking cool season grass? • What grass breaking dormancy now? • What grass are most lawns around here?
