We ended up ordering 50 of each variety of vine, instead of 30. This is due to a volume discount. It was significantly cheaper to order the 150 vines instead of 90 vines. As a result, we needed to til and fertilize some more ground. Melissa rototilled an eighth of an acre. that brings us to a quarter acre now. We also put up some poles. I've decided to rent an auger machine to drill all the holes, as there will be many to be dug.
