Like Goose said about lime. Also if you want a green thick lawn keep these Holidays in mind. ST patricks fertilize full rate Memorial Day fert 3/4 rate July 4 fert1/2 rate Labor Day fert full rate. use a lawn fert with as close as u can to a 3-1-1- ratio ex,20-8-8 or 10-5-5 for good root and stem dvelopement.
If you follow this be prepared to lose 1 day a week for cutting!
