I plan to start about 80 new vines next spring. In some books I've studied,
(such as Cox's Vines to Wines) it is suggested to have a backhoe dig and
refill a 3' x 3' ditch in the fall, prior to spring planting. Other books
have suggested you should do no more than roto-till the ground in the fall,
and that wholesale sub-soiling is unnecessary.

Does anyone have thoughts on the issue? How do you prep your own new
plantings?

Thanks,
Paul
