Hi folks. Im in need of advice. I did a turf reno which consisted of taking out the previous sod job that was dying. We took in down 4 inchs and replaced it with new topsoil 4 to 6 inchs. The topsoil consisted of sand black topsoil and peat mix. Up here were in a very sandy area so weed need to take multiple ph tests and add lime to bring up the ph . So we added lime grass seed and fertilizer. The new lawn came in the grass looks great except for its patchy and looks like it just needs to fill in. im just wondering we did the job in the spring and aerated again in the fall and added more seed fertilizer and lime in the fall. I my main question is should i aerate in the spring add more grass seed and fertilizer or just fertilize and cut the lawn all summer leaving 2.5 to 3.5 inchs high will the lawn fill in over time on its own. Thanks for the advice.
