Selecting, Establishing and Maintaining the Fescues
|
Tom Samples, Associate Professor Ornamental Horticulture and Landscape Design
|
Four fescue species are maintained as lawngrasses in Tennessee.
|
Originally from Europe, these perennial, cool-season lawngrasses are an integral part of many Tennessee landscapes.
|
They grow best in deep, well-drained soils at air temperatures from 60 to 75 F.
|
High temperatures and drought often slow their rate of growth during late spring and summer.
|
Species and varieties may vary in color, leaf texture, stand density, disease resistance and tolerance of shade, high temperature and drought.
|
Tall fescue is adapted to a wide range of soil and climatic conditions.
|
This mediumto coarse-textured lawngrass tolerates high temperatures, drought and wear.
|
Tall fescue is usually best adapted in areas of the lawn receiving full sun or in light, open shade.
|
Turfgrass breeders continue to search for dark green, dense and disease-resistant tall fescue varieties.
|
Chewings , hard and red fescues are known collectively as fine fescues because of their narrow leaf blades.
|
Seeds of several fine fescue species are often mixed and marketed for use in shade.
|
Although they have excellent shade tolerance and good drought tolerance, the fine fescues are not particularly tolerant of high temperatures.
|
Tall and fine fescues establish from seed faster than Kentucky bluegrass.
|
They are also more tolerant of acid soil conditions, shade and drought.
|
Although tall fescue has short below-ground stems , most new leaves and tillers originate from the crown and not from nodes on rhizomes.
|
As a result, this lawngrass has very weak sod-forming characteristics and a bunch-type growth habit.
|
It may be necessary to broadcast seed over the lawn or slit-seed the lawn every two to three years to maintain a uniform,
|
dense and weed-resistant turf.
|
Tall fescue is best adapted to fertile, moist soils but tolerates wet soils of low fertility.
|
Leaf blades are flat and rigid.
|
Seed of many Leaf Blade improved, turf-type tall fescue varieties is marketed in TennesRhizome see.
|
Several of these Daughter varieties are higher Plant in overall lawngrass quality and more Adventitious Roots disease resistant than 'Kentucky 31' tall fescue.

|
Chewings fescue forms a very dense, finetextured and upright lawn.
|
Leaf blades of chewings fescue are thin, bristle-like and stiff.
|
This noncreeping, bunch-type lawngrass is well-adapted to acidic, infertile soils.
|
Chewings fescue does not usually tolerate wet, fertile soils or the high and low temperature extremes associated with sites exposed to full sun.
|
Hard fescue is a bunch-type lawngrass with tough, bluish-green leaves and an extensive root system.
|
Hard fescue forms a dense, somewhat tufted, low maintenance and low quality lawn.
|
Although hard fescue has limited high temperature
|
tolerance, it is sometimes used alone or in grass and grass-legume mixtures for erosion control on ditch banks and along roadsides.
|
Often referred to as creeping red fescue, this lawngrass is similar in appearance to chewings fescue with one important exception it has a creeping growth habit.
|
Two distinct types of red fescue are F.
|
rubra ssp.
|
rubra, a relatively strong, sod-forming type and F.
|
rubra ssp.
|
trichophylla, with short, slender rhizomes.
|
Leaf blades are thin, bristle-like and deeply ridged above.
|
Red fescue forms a very dense, fine-textured lawn.
|
The rate of vertical growth of red fescue is slow compared to most cool-season lawngrasses.
|
The overall quality of a red fescue lawn often declines rapidly if an excessive rate of nitrogen is applied.
|
Red fescue is usually adapted to soil and climatic conditions favorable to chewings fescue.

|
Tennessee is located within a transitional zone between temperate and subtropical climates.
|
Fescues maintained in this transition zone often experience high temperature and drought stresses during extended hot, dry periods in summer.
|
Tennessee can be divided into four climatic zones which favor the growth and persistence of
|
certain lawngrasses.
|
Generally, the fescues are not well adapted in warm humid Zone IV.
|
Similarly, the moderately warm-to-cool humid climatic conditions in Zone III usually favor warm season lawngrasses including bermudagrass and Zoysia.
|
The fescues are generally adapted in cool-to-warm humid Zone II and cool humid Zone I.
|

Four lawngrass climatic zones in Tennessee.1
|
Fescue lawns are commonly established from seed or by transplanting sod.
|
The preparation of a firm planting bed with appropriate fertility is critically important to the growth and performance of young seedlings or newly-transplanted fescue plants.
|
For best results:
|
1.
|
Test soils six to eight weeks before the intended planting date to determine soil phosphorus, potassium and pH levels.
|
2.
|
Stockpile existing topsoil from new construction sites before excavation and construction begins.
|
3.
|
Control [i.e.
|
Roundup application according to instructions on the product label] troublesome perennial weed grasses and broadleaf weeds.
|
4.
|
Remove all debris (i.e.
|
wood, pipe, rock, discarded cement, brush and construction
|
scrap) that may obstruct the growth of fescue roots and restrict soil water movement.
|
5.
|
Establish a rough grade which directs water away from the house.
