I have 4 varieties of hops now (Cascade, Centennial, Chinook, Willamette) and I will probably add 2 or 3 more types in the spring. These will be planted in-ground, for the long term.
So:
1. How far apart to put different varieties so as not to confuse them?
2. Do you plant something else in between to act as a median, maybe virginia creeper or some other vine-thing?
3. If I just leave the bines up at the end of the season, will the next year's growth also come out of the old bine, or is it totally dead?
4. I am thinking a trellis would be nice, will they grow ok, say 8 vertical feet then 10 horizontal feet?
