I have a lawn that we mow and fertilize that has barely grown since early June. He waters every day for 30 minutes per zone. There are some greener areas, but mostly dead/dormant grass. Soil Test shows low nitrogen, low potassium, and a pH of 7.6. I know this needs to be fixed, but I feel like it would at least green up a little? I have put 3 applications of fertilizer on it already. Disease, or does pH, nutrients matter that much? Weeds even have a hard time growing.
