I have a commercial account that i mowed this year. Fertilizing was done by Liqui-green. They just told me they want me to provide full service next year. Total acreage is 5.5, but the area in front of their main office is big problem. It's about 2.5 acres. Lots of bare spots....some 4' X 4'.....some good grass and some thin areas. Some thatchy areas. Not a lot of weeds, but a few. If I had know sooner, i would have done a fall aeration and overseed, but it's too late now. So.....my question is.....do I fertilize in early march with crabgrass preventer and then aerate and overseed in early april, or do I aerate and overseed first.........I want some help from mother nature on the watering, so that's why I am thinking about seeding first. No good way to set up sprinklers and I am 20 miles from the site, so it would be hard to do it all myself if we had a dry spring........can't expect any help from them on the watering.
