According to Great Day Improvements, sowing grass seed in Tennessee should be done in the early fall or early spring. Some of the best types of grass listed for Tennessee include rye, fescue and Kentucky Bluegrass.
Grass germination should occur within two weeks of planting seed. Grass seed should be watered frequently, as it is one of the main factors for germination. Grass seed also germinates best in loose earth and not hard, compacted ground. Adding good compost to the top layer of dirt can aid in germination of grass seed and help give nutrients for growth, according to Great Day Improvements.
