Last spring, I decided to replace my bermuda lawn with Zeon zoysia. The contractor came in and sprayed some herbicidal cocktail on the grass and it began to brown out in a matter of hours. Five days later he came back to lay the new sod. He used a string line trimmer to scalp the dead turf, spread some compost mixture on top and laid the new sod. The new zoysia took off wonderfully. About 5 months later I start noticing quite a few patches of bermuda in the new sod. He came back and sprayed Fusilade II on the bermuda but I suspect he diluted it improperly and it also killed a fair amount of the zoysia.
Long story short, he apologized and has offered to come back and re-sod the lawn. What should be done this time to help ensure that any remaining bermuda doesn't re-appear again?
