This season, we've installed 69 pallets of emerald zoysia purchased from Super Sod. We noticed when installing the sod that there were weeds... After establishment watering, I'm now faced with horrific amounts of weeds that make me look bad! On one of the jobs, we had 2 full pallets not last a week and had to replace...It was not the water, because it was only specific rolls of grass placed next to each other. We installed 52 pallets purchased from NG Turf, and don't have the weed problem and no mortality. I'm not sure if its just an emerald zoysia thing, or if Super Sod let their guard down this year....Not sure if I'll be buying from them again, although I demanded a 2 pallet credit on my next order. Lawns are full of purple sedge and crabgrass; some rolls even have bermuda in them. It's going to be a costly long road for chemical treating these lawns.
