This is Zone 1. The program starts running at 0445. I aerated back in april. This was my second year in the house but aeration is a yearly thing in my maintenance program. I am going to perform a soil test this week or next. I am thinking its a little to late in the season to get it to turn around and green up for me. Do you think maintaining the Bermuda at to tall a height could cause this? I currently maintain it at 3", I know that is to tall but because of the poor grading from my builder it scalps it in areas at 2.5" with my 36" WB. I may just try maintaining it with my 21" Honda next year, but cutting with the big mower makes it so much easier especially after cutting other peoples grass all day.
