Turfgrasses usually grow best in full sun and in nutrient-rich, well-drained soils. Topography and soils of Tennessee influence how turfgrasses perform.
East Tennessee is well adapted for Cool Season turfgrasses. East Tennessee is mostly mountainous, with broad, fertile valleys. Soils were formed from limestone, sandstone or shale.
The Central Basin's rolling hills in middle Tennessee reach an elevation of 800' or more. This area features both Warm Season and CoolSeason turfgrasses. This area is also known for its limestone-based, phosphorus-rich soils.
The Highland Rim surrounding the Central Basin is composed of hills often reaching an elevation of 1,000' or more. Cool Season turfgrasses usually perform very well on the Highland Rim.
Southwest Tennesse's near sea-level elevations grow Bermudagrass and Zoysia as the predominate turfgrass species.
In Tennessee, residential lawns account for nearly 70 percent of the total turfgrass acreage and an average-sized lawn is more than 24,000 square feet in area.
Turfgrasses often require greater amounts of one or more nutrients than the soil can provide. In Tennessee, the nutrient requirement of turfgrasses is often cyclic, varying by season and plant growth rate. These and other factors deserve consideration when developing an effective fertilization plan for turf.
Begin with a soil test to determine where the deficiencies are in your soil. Then add amendments to the soil to correct those deficiencies and then add nitrogen to maintain a healthy soil suitable for growing turfgrass.
