in september, i bought 5000 sq.ft. of sod. the weather was suppose to be great, but ended raining all week. the sod ended up sitting on pallets for most of the week, laying down rows whenever the weather gave way. i noticed as time passed, the sod was steaming and hot. i finally finished laying down the sod and watered it just like i was suppose to, now 4 months later i have dry/burned patches on half of my yard. i am not sure if the sod is ruined, if so, what can i do to repair it?
