I moved into a new construction house last year. Because of circumstances I overseeded my lawn with cheap bluegrass mixes in the fall(kenblue, abbey and baron I believe). This year the lawn is doing pretty well but I am going to overseed with Galaxy blend and Bedazzled this fall. My main question is should I keep up my good cultural practices to keep the grass I have healthy or should I just let it be ( no water etc.). Currently I cut about every four days, water deeply only when needed( only once so far this year) and fertilize with grains. Much of my lawn is thick and healthy so I don't know how well new grass will compete in these places when I over seed.
