I'm excited to put a new addition of a 24' x 40' high tunnel up on new ground- which is on mixed grass that has been there for 30+ years. For years I would have removed the sod with tractor- brought in compost, manure, dirt, etc and start building garden soil. Now days after reading years of articles I am tempted to change my ways and leave the orchard grasses and cover with compost, manure, straw, cardboard- seem to be the right thing to do. I am still very nervous that I'll be tormented by grass popping up in my rows forever.
My question: what do you recommend I do and ease my worries!
