    • Ag. Concepts Lawns
    • Turfgrass
      • Lots of kinds of grasses
      • Corn, Wheat, Barley,
      • Sea Oats
      • Ornamental Grasses
      • Turfgrasses
        • Lawns
        • Pastures
        • Sports fields
    •  
    • Grass Growth Habits
      • Bunch type –
        • Grows where a seed lands.
        • Bunches get thicker
        • Don’t recover as well
      • Creeping –
        • Start where seeds land or by sprig
        • Spread by rhizomes & stolons
    • Functions of turf
      • Utility
        • Stabilize soil – reduce erosion
        • Cool areas by breaking up pavement
        • Remove toxic substances
        • Reduce CO 2
      • Ornamental
        • Enchances landscapes
      • Sports
        • Reduce injuries
    • Turf Quality
      • Visual
        • Density- # blades per inch
        • Texture – width of the blades
        • Uniformity
        • Color
        • Growth Habit
        • Smoothness
    • Functional quality
      • Rigidity – resistance to compression & wear
      • Elasticity – Ability to spring back after compression
      • Resiliency – Ability to withstand damage
      • Recuperative potential – Ability to repair itself after damage
    • Transition Zone
      • The area where neither a cool season grass or a warm season grass will grow well all year round
    • Turfgrass - Zones
      • Warm season (Brown)
        • C4 photosynthesis
        • Reproduce and grow best in hot weather (80 – 105)
      • Cool Season (Blue)
        • C3 photosynthesis
        • Reproduce and grow best in cool weather (50 – 75)
      • Transition Zone
        • Cool season grass grows well in Apr – Jun & Sep – Nov
        • Warm season grass grows best in June - September
    • Transition Zone Grasses
      • No one type of grass will do well all year
      • Both types of grasses will grow & live. In general the cool are more successful
      • Possible to use both
      • Requires more intensive maintenance if a cool season grass is required
      • Or use a summer time warm season grass which goes dormant (and brown in color) in fall - spring.
    • Cool Season Grasses
      • Need cold winters (with temperatures below 32 ° ) and warm summers.
      • Grow best at 60 - 75 °
      • Need regular rain in summer
      • May go dormant in summer heat & drought
      • Kentucky bluegrass, perennial rye, tall and fine fescues, & bentgrass
    • Warm Season Grasses
      • Tropical origin and thrive during the scorching summer heat.
      • They are tough and form a dense lawn cover that thickens as they age.
      • Their leaves turn brown in late fall and don't green up again until warm weather returns.
      • In general they are green about half the year.
      • Bahia, Bermuda, Centipede, St. Augustine, Zoysia
    • Tall Fescue
      • Cool season grass
      • Tolerates some shade
      • Plant by seed or sod
      • Mow 2 – 4” height
      • Moderate drought tolerance
      • Needs moderate fertilizer
      • Coarse textured, clumpy
      • Does not spread well, slower to repair
      • Deep green color
      • Predominant lawn grass in Piedmont, Va.
    • Tall Fescue Varieties
      • Kentucky 31 – Old standard grows in many lawns, now primarily used as a cheap seed for little-used areas like roadsides.
        • Has endophytes which make it problematic for pastures – esp. horses.
        • MaxQ is endophyte free tall fescue
    • Other Tall Fescue Varieties
      • Used primarily in blends : Durana, Penn 1901, Forte', Signia, Oncue,  Virtue, Rebel Sentry and Duster
      • Buy blends for specific purposes:
        • Shade
        • High traffic
        • Drought resistance
      • New varieties have finer texture
    • Tall Fescue
      • Rolled leaf
      • Collar
      • Ligule
      • Auricle
      • Rhizomes
    • Kentucky Bluegrass (Poa pratensis)
      • Shade tolerance: poor
      • Planting: seed or sod
      • Mowing height: 1 1/2" - 2 1/2"
      • Water: needs regular watering, will survive droughts by going into a dormant state
      • Spreads and recovers well – good sports turf.
      • Fertilization: needs regular fertilization
      • Cold/heat tolerance: Good cold, poor hot
      • Best lawn grass in appearance
    • Kentucky Blue Grass
      • Boat-shaped tip
      • Parallel blades
      • Short ligule, no auricle
      • Underground Rhizomes
    • Perennial Ryegrass
      • Germinates very quickly
      • Poor shade tolerance
      • Short-lived grass may only live one season
      • Only grows by seed – not sod
      • Mow at 1 ½ to 2 ½ inches
      • Poor drought tolerance
      • Bunch type grass – no stolons or rhizomes
      • Cool-season
      • Used for over-seeding dormant warm season turf & quick green-up
    • Perennial Ryegrass
      • Has auricles
      • Folded new leaves
      • Bunch grass
        • No stolons
        • No rhizomes
    • Bermuda Grass
      • Needs full sun
      • Drought tolerant
      • Warm-season grass
      • Plant from sod, seeds or plugs

      • Mow between ½ and 2”
      • Turns brown when soil temperature
      • falls below 60 °

      • Deep green
      • Drought tolerant
