I'm going to offer aeration and fert. together. I'm looking for recommendations for fertilizer that will show some quick results; but the main purpose is to build a stronger, thicker lawn. I'm thinking of laying this down after aeration5-10-31 10%FE Any other suggestions? The area in question has a low sand content; irrigation water is running across the sidewalk in a sheet after 20 minutes. St. Augustine/Floratam is usually thin and pale in this area; I'm guessing it's because the water and ferts are going through the storm drain and into the retention pond instead of into the soil.
