Just for grins I applied 2 different brands on Centipede grass on each side of a walkway. One side got Scott's 22-3-3 weed and feed which costs $32 for a 15 K foot bag. The other side got Lesco 20-0-20 with Atrazine which costs $20 for a comparable coverage bag. After 4 weeks the turf on each side of the walk was just about weed-free, but the Lesco side looked greener and healthier with more runners and thicker blades. One yard is a small test sample to be sure, but all our Lesco lawns are looking good this season. Have any of you guys run comparisons like this in the past?
