I looked at a job today.. pretty simple job, edging is all existing brick and the sprinkler system is good. (I might suggest changing the heads though) The problem is, the lawn has been overtaken with bermuda grass. I would for sure try and kill the bermuda as well as I can... but after that would it be better to strip off the top inch or so or just till it all in? Im in NorCal and have seen quite a few resods done over bermuda that were fine for a couple years maybe but then the bermuda started coming back in. Also, anybody used turflon to successfully kill bermuda? edit:forgot to mention, the new sod would be a dwarf fescue / bluegrass mix.
