Ok, so I'm blowing up my yard and starting out fresh and need some advice. Bermuda grass was heavily established in my yard when I bought my house 4 years ago and regardless of what I try to to I just can't get rid of it. So I wanna destroy every bit of grass and start over. My plan is: 1. Apply multiple applications of roundup as soon as I can before the last frost (I'm in zone 7, Southern Maryland). My question about this is should I apply the roundup now or wait til after the last frost. Second, I live on the water and I am afraid that using too much roundup before a rain could drain the roundup into the river and cause some ecological problems. If I shouldn't use roundup what organic product will kill every bit of grass or what technique can I use to ensure it doesn't drain into the river. 2. Use a tractor and till the entire yard for two reason. First to help break up the deep bermuda roots and second to allow the new grass to seed easier. 3. Lay down grass seed. Multiple questions here. When should I plant the grass seed? I would assume the timing would be dependent on the last frost of the year but where in relation to that. Second. What is the best type of grass to use for a zone 7 area? I have kids and would like something that is soft to the feet but also somewhat drought tolerant? Any suggestions? Should I apply multiple applications of the seeding to ensure full coverage or just follow the instructions on the seed bag? 4. Lay down some hay?? I don't know if this will help at all but you always see this in yards after new construction and it seems to work out well. Any advice you can give me is much appreciated. I'm pretty good at growing vegetables and flowers but I'm a little new to the grass renovation.
