I just want to know what is a good time to aerate and over seed in the spring. I am looking to aerate a customers lawn next Tuesday. I will also be over seeing and putting down starter fertilizer for the seed. Am I doing this to early?? The reason I want to do it now is because I am planning on starter to cut the second or third week in April and I want to give the seed proper time to grow before the first cut of the season. Any suggestions would be helpful. Thanks.
