We put in new TIFGrand sod on a property about a month ago and it's not doing well. The sod was put down and began getting watered within a day of being cut and was watered lightly 2 times a day for a couple of weeks. 3 weeks after install I was a little concerned about the stress so I applied 1/2 pound N, 1/2 pound P and about 2/3 pound K with iron and micros. We put in 3" of new turf mix (sand, compost and screened topsoil) and we've recently had some good rain. The sod had a little bit of dormant turf in it (about 30%) when we put it down but the brown in it has increased. Anybody have any idea what's going on here or what to try to improve it? If it doesn't start looking better in the next few weeks, I'm probably going to have to pull this out and do it again, something I'd really like to avoid.
