John, be real careful with the Roundup. My Bermuda has greened up pretty good already. I have nothing in my yard but Bermuda by spraying Podiamine and Atrizine , both pre-emerge, in Feb and Oct. and have not had a need to Roundup. As said for the stickers and broadleaf you need 2-4D. As mentioned be careful with a hand sprayer for overlapping too much.
My yard was a mess when moved here and by using the above method even the guys that do this for a living say I have the best looking yard in town.
If you have any questions give me a call or I can come look at it when I come over,if you want me to.
