I grew up in a st. augustine house and really only know st. augustine, but have a new house with bermuda so i am on a steep learning curve here. the sod was initially riddled with weeds and i applied treatment last summer to deal with the problem. low and behold, my weed problem is back with a vengeance. i got a quote from a grass treatment guy for $400 which included 4 treatments through the next year, which seemed quite pricey. my lot is somewhere between .25 and .5 acres, so its not a huge yard, but sizable. for a nice looking yard this summer, should i spring for the $400, post-emerge it myself with the effective product i currently have, or buy a pre-emerge product and treat myself? bermuda seems to be a ton of maintenance year-round and for a pre-emerge treatment, i know i am running out of time if not out of it already.
