Hello, I'm planning on a new garden next year (240' x 60')
and need some help... only thing I have done so far is, picked out the spot, and did a soil test with the local extension..... I have a tractor, and rototiller..... One of my first questions is should I somehow destroy the grass before I rototill? ..... Another question is what depth should the ground be tilled?

Any other device owned any aspect of this project would be greatly appreciated.

Thank you


paul
