I am a homeowner, not a lawn professional, so I thought I would turn to the pros on this site for help. I purchased a 1.15 acre house lot here in NE TX that used to be native pasture land. I have neighbors on all sides with established yards. The soil is very sandy, and the place is covered up in every southern weed imaginable right now. Sand burrs are completely our of control in the summer time, though I did not see any last weekend when I mowed it. I am sure they will be back in full force once it gets a little warmer. Late last spring (during the drought we had) I borrowed a tractor and shredded the lot, then disked it up and smoothed it out. We never got any rain, so the weeds really took over. Then last September, once we finally started getting some rain, I put out 50 pounds of Bermuda grass seed. My question is what can I do to kill all the weeds, but not hurt immature Bermuda grass? While researching the lawnsite to see what to do about the sand burrs, I found this I bought an ATV sprayer with a boom, and plan to put out roundup as posted above. What will this do to my young Bermuda grass? Will it kill out the weeds, too? What would you recommend I do? Should I spray it heavily with roundup and kill everything, then reseed? I hate to do that since 50 pounds of Bermuda grass seed it about $260, but I want to get some good grass established and get rid of these weeds. At what point should I fertilize? I bought a used Exmark ZTR mower during the winter and I will keep it mowed regularly. Also, I do not have a water meter set, so I can not water the lawn, I will be relying on the rain that Mother Nature brings. I will have to haul water for the sprayer. Thanks for all your help!
