Tall Fescue Strategies

• High turf quality, rapid establishment

• Rhizomes - Advertise and promote XRE

• Higher percentage of plants with rhizomes

• More rapid rhizome production

• Verification of rhizomes in mown turf

• Brown patch

• Screening at multiple sites - remove survivors

• Screening progeny from drought / rhizome work

• Drought tolerance and recovery - 3 cycles GA

• Salt tolerance

Rhizome Reproduction

• Underground repair

• Kentucky bluegrass, creeping red fescue, bermudagrass

• Present on certain tall fescues, observed on plants

• Wear, divot repair

• Soil compaction, season influence repair

Use this slide if you are going to use a picture. To make a presentation interesting, you should have images on at least 50% of the slides. Without visuals, you will quickly put people to sleep. You might anyway, but you have a better chance of keeping their attention if you use some nice visuals. Pictures can make the presentation look more professional.

Delete this text and place picture in same area, lining picture up with top of yellow text.

Use 72dpi jpgs images.

To shrink picture proportionally once it’s on the slide:

1. Click on the picture (note corner handles).

2. Hold down the Shift key, then press and drag a corner handle towards the middle of the picture.

3. Release the Shift key first then the mouse.


SRX 8LM Tall Fescue

• Available 2007 - replace SR 8250

• New material with rhizomes

• Mown turf rhizomes

• Highest brown patch resistance

• Very dark green color

• Very fine textured

• Highest turf quality









Defiance XRE Tall Fescues with Rhizomes

• Grande

• Grande II

• Crewcut II

• SR 8600

• SR 8250

• SR 8550

• Tulsa II

• Regiment II


Turf-type Tall Fescue

• Strengths

– Excellent wear tolerance once established

– Drought tolerance useful many sites

– Can be mown at 1/2 inch

– Shade tolerant

– Tolerates broad range of soils

– Speed of establishment

• New data Ohio State - new varieties can maintain quality with wear after 15 weeks, spring establishment


Regiment II Turf-type Tall Fescue

• High percentage of rhizomes

• Rapid rhizome expression


• Fine texture

• Dwarf growing habit

• Superior density, weed resistant

• Quick establishment

• Rapid recovery

• Early Spring green-up


Blackwatch Turf-type Tall Fescue


• Fine texture

• High turf quality - recommended in many states

• Open, dwarf growing habit

• Reduced brown patch incidence


• Quick establishment

• Rapid recovery

• Early Spring green-up


Guardian 21 Turf-type Tall Fescue


• Fine texture

• High turf quality

– Consistent high performance under all management levels

– High performance in all climate zones

• Semi-dwarf growth habit

• High wear resistance

• Reduced brown patch incidence




• Weaknesses

– Bunch-type growth

– Speed of repair slow

– Rhizomes in new varieties may help

– Need more winter-active growth

– Brown patch susceptibility - in enclosed shade can severely damage

– Old cultivars lacked density and texture, new cultivars finer textured, darker green, higher density



• How to use

• Best results when blended with Kentucky bluegrass - 85 to 90% Tall fescue

• Blending with Texas x Kentucky hybrids may be useful in stress sites

• Brown patch reduced in blends

• Establish in spring or late summer

• Provide protection against Pythium and seedling brown patch



Newest turf-type tall fescues compared to older cultivars


Tall Fescue Turf Rhizome

• 4 inch wide divot cut May 4 , 6 weeks growth

• Tall fescue rhizome 3 inches

from mother plant

• Not as many as in bluegrass

• More rhizomes observed in fall than spring


Tall Fescue Strategies• High turf quality, rapid establishment

Tall Fescue

• Advantages: (New Varieties– Dark green color– Heat and wear– Extensive root system– Good density– Good establishment– Good disease resistance

• Disadvantages–Low shoot density–Low temperature injury–Weak sod forming–Thinning stands leads to clumping
