I am hoping for some suggestions. We have a garden spot. My husband will till it, then we'll end up getting lots of rain before I can plant. By the time I am ready it is completely covered in weeds Mainly that low to the ground stickery type. He usually mows then tills again. Is there anything I can put on the plot to kill the weed completely before planting that won't harm the seeds or emerging vegetables? How about at the end of the growing season, can I put roundup on it to kill everything and will it all be washed away by the following spring? I really need help with this because this area gets so weed infested that I simply can't keep up with it. Or should I just have him till it and then lay the black plastic down and plant through holes in the plastic?
