Turf FactsApprox. 50 million acres of

managed turf in US

As of 2004, the annual value of the U.S. turfgrass industry was $35 billion.

Nationally, homeowners spend $6.4 billion per year on lawn care.

Get to know your grassType:

Cool Season• Fescue, Kentucky

Bluegrass, Ryegrass, Bentgrass

Warm Season• Bermuda, Centipede,

Zoysia, St. Augustine

Page 4: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Name of seed producer Seed Lot # Seed Variety % Purity % Germination % Weed or Crop Seed % Non-Seed Material Date when seed was last tested for Germination

Seed Label Information

What are you buying????

Page 5: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

How much seed do you need?

Based on % pure live seed & # of plants required for area

GOAL Establish 1000 plants per

square foot for newly seeded lawn

Page 6: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Pure Seed or MixtureMixture

meets wide environmental & use requirements select mixture based on desired characteristics turfgrass vary in resistance to disease and insects

What can be mixed? Any turf that spreads by rhizomes or tillers (Fescue, Bluegrass, Ryegrass) Do not use stolon grasses, tend to segregate

• Bermuda, Bentgrass, Zoysia, Centipede, St Augustine)

Soil Test

Page 9: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Soil pHpH governs the availability of nutrients & activity

level of microorganisms

Page 10: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

pHMost lawns grow best in a soil pH 5.5 - 6.5

Low pH < than 5.0 (acidic soil) Dolomite or Limestone Avoid over liming - weak growth will result

High pH > 7.0 (alkaline soil) Ammonium sulfate , Aluminum sulfate,

Sulfuric acid

Page 11: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Establishment StepsRake & Remove DebrisWeed Seed GerminationAdd Nutrients & Lime

Soil Test Recommendation Phosphorous (2-3 lb per 1000 sqft)

Application of Seed, Sprigs, Sod, Plugs

Rake & Roll • ensure good soil contact

Page 12: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Water

Seedbed must stay moist for seeds to germinate

1st 3 weeksSeed & Sprigs

Keep moist by frequent, light watering until new root system develops

Page 13: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Sodding

Any turfgrass that spreads by rhizomes or stolonsBest Time: when turfgrass is actively growingAdvantages:

Instant Lawn Less Weed Competition Decrease Erosion

Disadvantages High cost

Page 14: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Installing Sod Cost More

Sprigs & Plugs

Time of Year Early Spring to Late Summer

Spacing• 10-12” apart, checkerboard

Planting set root systems completely under soil surface

Soil Contact Roll area after planting

Page 18: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Water•Sod & Plugs

– Heavily soaked so that soil underneath is completely wet

Page 19: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Establishment

Mowing as soon as grass gets high enough to cut at its

optimum height

Weed Control 1st year chemical weed control is discouraged

Page 20: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Converting Old Lawns

Grass selection: Bermuda, Zoysia, Centipede conversion2 year for conversionSteps:

1. Cut Lawn Closely 2. Dethatch / Aerification 3. Correct pH / Nutrient Level 4. Sprig / Plug / Seed 5. Roll & Water Thoroughly

Fertilizer Application Type of grass Soil Analysis Fertilizer Burn

• Salt Toxicity

• Check spreader calibration

Page 23: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Spreader Selection & Application

Low quality spreader can leave streak or patches in the lawn

Causing unsatisfactory control of weeds, insects, as well as poor fertilizer performance

Page 24: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Drop vs Rotary Spreader

Drop Spreader meter out fertilizer and

drop it directly on lawn

Small lawn Doing job as precisely

as possible is important don’t mind taking a bit

longer

When to Fertilize

Cool Season Grass Fescue Sept, Nov, Feb, April

Warm Season Grass Bermuda: April, May, June Centipede: June Zoysia: April, June St. Augustine: May, June, July, Aug

Page 28: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

FESCUE ALERT!

Fertilize fescue with caution. Too much will make it disease prone and

drought sensitive. If you haven't fertilized in six weeks, apply

now at half the rate recommended on the bag.

Lack of Water Stress Signs

Grass turns a silvery blue in stress area Footprints in lawn, does not spring back

Page 34: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Mowing

Avoid Scalping

Never cut more than 1/3 of leaf blade in one single mowing

Page 35: Establishing Lawns Horticulture Mr. Fitzgerald. Turf Facts §Approx. 50 million acres of managed turf in US §As of 2004, the annual value of the U.S. turfgrass

Mowing too low

Decrease grass ability to develop food reserves for stress & dormant periods

Expose growing point to heat/cold

Larger % leaf cut the longer period root will not grow = shallow root system
