I grow hops… I have 2 Chinook bines and 2 Cascade plants growing in Eastern Massachusetts. I’d advise ordering your rhizomes from freshops.com, that’s where I got mine and I was very happy with the results. There is also a good tutorial on the site.
The big things are to fertilize, give them lots of water and all the sun that is possible.
1) Before you plant the rhizomes, dig much deeper (I did 4 feet down, but I think that was overkill) and put in a blend of compost, fertilizer and good soil. As the plant puts down roots, which is will quickly, it’ll hit this nutrition which will help it to grow better. After it’s buried, put compost and fertilizer on top and get it very wet. Also, make sure you have decent drainage. You want to provide it a lot of water, but you don’t want to drown it. You’ll want to do all of this after the threat of frost is gone.
2) Ensure that you plant it in the sunniest place you can. I have seen very varied results over a difference of just 12 feet because of a difference in shade.
3) Set up a strong trellis or support structure right away. I have 4“x4” beams going 16’ high with a cross beam that lowers so I can pick the hops easier. I also have each bine on an individual rope so I can lower them independently. I used to have a PVC structure, but the hops pulled it down in the 2nd year. They weigh A LOT and I wasn’t even at full crop yet. If you have to set up the support structure after a season or 2, you will do root damage digging the anchors in for the support.
4) Water them every day. Unless it rains really hard, water them. Try not to get the leaves wet when you water them, as this can promote diseases & pests in the hops.
5) Strip the leaves from the bottom 1’-2’. This will deter pests.
6) After the hops start to grow, select 3–6 bines from each base plant to run up the lines. I have 4 plans that run up 8 lines. I run 3 bines up each line.
You can’t count on a lot of hops in the first season. I got a few ounces wet, maybe 3 dry. Second season I got 5 lbs wet. Third season should have been good, but I did some damage creating a new support structure and delaying their growth because they had nothing to grow on. This year should be epic. That said, if you take good care, give them a lot of sun and nutrient, you should have enough wet hops for aroma/flavor additions and possibly dry hopping this year. Order your rhizomes soon, though. Hope that helps, let me know if you want more details.
