This I can actually provide some feedback on!
About ... circa 2010 or so, I started growing hops in Alexandria, VA. It was easy, TBH, I used nothing more than rotating sprinklers with a daily run about 30 minutes in the AM and PM. I had success with, let’s see: Centennial, Cascade, magnum, chinook & galena. I did not get good results from Kent Goldings. They grew, but never produced significant amounts of hops. I’d say in that mid-Atlantic climate my best results were from magnum and galena. I had 2 large trees I climbed and tied rope to, then dropped strands for the bines to climb. I wasn’t really taking it seriously, I just kind of had them and took them for granted until they produced.
in ’20 I moved to south Texas. After some reading I picked up Cascade rhizomes. They grew fine, but produced very little and died off before November, only 2 of 24 rhizomes survived next season. I did more reading and upped my watering, but we went into heavy drought conditions. Again I lost a large number of rhizomes before the growing season was over. After going basically 0 for 2 and tiring of watching my hops get sun murdered, I installed drip irrigation. I had about 16 cascade bines and got 24 ounces of hops week 1 of August. The drip irrigation was key, but some hops just simply will not thrive in this kind of dry heat.
I tried multi-head neo-mexicanus, they lived 2 seasons, grew, but would not climb, and produced nothing. They all died at the end of season 2. I replaced them with Triumph, they came up and grew, lost 1 of 6. No production, but they were alive at the end of growing season. The problem with neo-mexicanus is you’re blazing the trail trying to home grow them. There’s zero information on watering and care. I tried adjusting water to lower levels but then they would start to wither, so I added water back. I had one rhizome that was a small bush - maybe 15” wide, but that’s as far as it got.
Since I’m good with cascade I will probably stick with them. If the Triumph decide to grow this season, I’ll be glad, but if they turtle or otherwise don’t cooperate I’m thinking of trying a few chinook rhizomes.
Drip irrigation is a great way to take care of the hops. You can get a hose bib adapter, run some line underground to feed the area, and then drip lines to the rhizomes.
I don’t have trees nearby for this, so I basically made an 18’ tall clothes line from ‘rigid’ 1 1/4” pipe. I ran 4 strands of rope between the poles, and dropped rope from them. One side is on pulleys, so when the hops are ready, I untie the pulley side, drop the bines and pick hops.
