Can I kill crabgrass in my flower garden?
About a month ago I planted a sunflower garden along with many other types of flower seeds. I went crazy planting. I spaced each row about 12-14 apart and crabgrass has taken over like crazy. Is there any possible way that I can directly spray roundup on the crabgrass without killing my flowers? Trying to pull out the crabgrass will take forever.
