Certified seed will contain fewer weed and other crop seed contaminants and will be free of inert filler. Read the seed analysis tag before purchase. High-quality seed will have a high percentage of turf seed and a low percentage of weed seed, other crop seed, and inert matter. Likewise, the higher the germination percentage, the higher the quality. The analysis tag should be used to compare seed lots.
All turf seed sold in Kentucky is required to have been tested within nine months prior to sale.
Select the highest quality, even though it may cost slightly more than inferior quality seed. Since sod should offer immediate aesthetics, purchase only high quality sod. This sod is mowed regularly and is otherwise managed from planting to harvest to maintain reasonable quality and uniformity. This sod usually contains clumptype grasses, nimblewill, and broadleaf weeds, which are impossible or very difficult to control selectively.
