Overseeding is just applying new grass seed to your lawn. This can be done with a spreader or in conjunction with other services like aeration and slit seeding to improve your results. No matter the process of application we will recommend a certain amount of seed per 1000 square feet for your best results. More isn’t always better, the name of the game for seeding is seed to soil contact. The more soil contact the seed has, the better germination, equals better results.
