Normally I don't care much if my grass browns in July/August due to drought, which has happened again this year. However, we're going to try to sell our house next spring, and I didn't even think about trying to take photos of the outside before the lawn looked crappy. I know that fall is the best time to grow grass... any recommendations for a plan to get the lawn back into shape so I can snap some photos in October? As it stands now, the only green areas on my lawn are some patches of crabgrass and other weeds. Should I spray some weed killer, let the lawn sit for a few weeks, then plant grass seed and water continuously? Am I better off just using roundup and starting from scratch? Thanks!
