This spring I installed an irrigation system and new sod. Following the advice of the landscaper, I watered the new sod 3x per day for 2 weeks then cut back to 1x per day. At first the lawn looked great. Then slowly the lawn started get brown spots. I questioned whether a fungus problem was beginning. Our landscaper assured us to continue watering. The brown spots continued to enlarge and calls to our landscaper went unanswered. Within days the entire lawn looked like straw. I then cut back on the watering to about an inch per week and started using Scotts Fungus control. I have put on 3 fungicide applications over 6 weeks. The lawn appears to be coming back very slowly but doesn't look good at all. Today after a good rain I went out and pulled some weeds only to have the sod pull right up. There doesn't appear to be any root development. In terms of fertilizing, I have a lawn service come out. They applied fertilizer within 2 weeks of the sod going down and just applied the summer application in mid-July. Now that I see no rooting taking place, should I increase the watering to everyday again? But will this cause further fungus problems? One last matter - grubs. I applied a season long preventor for grubs in later April or early May. Should I reapply this product? I hope you can help.

I am not sure what really happened to your sod, but if you have no rooting after this much time has elapsed, I doubt that the sod will root at all. The watering routine you used seems fine. The soil should have been prepared before the sod went down. If that was not done, I could see where you might have limited rooting. It might also be possible that you did not receive quality sod (especially if you were pulling up weeds). I would consider re-sodding, with the proper soil prep ahead of time, since it seems that this lawn has doen nothing but struggle to survive. As for using a grub preventer, I doubt that you need to since there are no roots for grubs to eat, unless you know for sure that you have a grub problem and they might be the reason you have no roots.
