I have been reading this board for a long time and have finally taken the plunge.Last weekend I picked out an area about 50 yds. x 20 yds in my back yard (I have a 3 acre lot) and did the first treatment of round-up. My plan is to treat it 2 more times between now and early September, wait 2-3 weeks and sow the wildflower seed mix directly onto the plot. Next year I will mow to prevent weeds. Questions...what am I overlooking (my goal is to have mixture native grass/wildflowers)? Who do you recommend as a supplier of quality seed, which I understand to be critical to this project? I am in the upper Cumberland plateau area of Tennessee (between Nashville and Knoxville).Any words of help/encouragement/advice would be much appreciated. Thanks.
