I have a problem that I figured I would ask you guys on to see if anyone had any answers. I did a job last fall where I had the customer kill off all of the existing grass, aerate the area, and then I blew in a compost/seed mixture (about 1" total compost, 80/20 mix of turf type fescue/perrenial rye). The seed came up beautifully and has done well since then - until 3 or 4 weeks ago from my understanding (around July 1). The customer has been very pleased until it started turning yellow in spots and dying out in other spots. I told her that I would be by there in the morning to take a look at it and see if I could notice anything obvious. The customer does not have an irrigation system, but I do not think that is the problem since here in Mid Tennessee we have had a lot of rain this year. The only problems the customer had was where I did the compost mix - other areas were sodded before. I checked another job I did a week later than this job (with the same parameters), and it does have a hint of yellowing in it also. Other jobs which I only did 1/3~1/2" compost show no signs of yellowing. My initial theory is that since we have had so much rain this year and the compost tends to hold quite a bit of moisture, the compost held too much moisture around the grass and basically drowned it. Does this sound possible? I have several pictures showing the area. Any ideas on what might be causing this would be much appreciated. This grass was in very good condition until this and I would like for it to get back to that condition if possible.
