I have a customer who I did a sod job for a couple weeks ago, about 550 sq ft around her newly installed above ground pool. She was so excited when we got done she asked me to sod the remaining 1500 sq ft in the yard. There is a tree in the area she wants me to re-sod that has exposed roots sticking up out of the ground roughly 2-3 inches. My question is, will I be alright to topdress the top of these roots with 3 inches of loom and then sod over it? Or will the sod not take?.......or later on down the road will it end up dying?
