My husband loves his John Deere and all the bells and whistles. Last year he rototilled our one acre back yard. Then seeded. So this year I have spent the last four months digging out crab grass and broad leaf plantain. I now have three more compost piles (that are too big. I also have a mound of plantains six feet tall. I use no chemicals because we have dogs. Should I just dig a huge hole and burn all the plantain? I am not going to seed again until spring because I am still not done and winter comes fast in Minnesota. I am 70 and I hurt everywhere. But that is for a medical site. Not here. Help!
