I would agree Danno. I have made a few that were over bitter. A key thing to remember Barry is that once they get growing it is difficult to know what they are so what I did was I engraved into wood what the varieties are because I have several. The sharpies that I originally had used was wearing off quickly so I engraved it into the wood. I would plant more of the flavor and aroma hops because the recipes usually need more of those than the bittering hops. It is very enjoyable to grow it.
Planted one plant 10 years ago, it now covers about 30 ft on my bee yards north fence and up to about 15 ft on some rope lines I put up for it. Dried some with a dehydrator and have kept it for about five years in a sealed plastic bag and it still smells good but have not got around to brewing yet. About those Japanese beetles you want to get some guineas they search and destroy any that they find, come to think of it I do not have any problems with small hive beetles either.
I've had hops a few years now in north Texas; DFW. This is not the ideal place to grow them.
Keep them watered, but not soggy. The flooding rains we had this year flooded my backyard several times. I will not get hops this year, but the bines ( ) have survived. Seems they will grow back all growing season, so long as the root is good.
Let them grow up as much as possible; 8+ feet, maybe 12 feet. They can be made to grow horizontal from there if need be, but yield is not improved that way. It may even be reduced. They won't bush out from being tied down. They will keep turning upward.
Since it gets so hot here, I do not cut back the first growth. I need all the grow time I can get. So far, this has worked.
Cut down the bines once they turn brown. Cover with mulch before the winter. They will come back. I use leaf litter, so I've not had to uncover mine.
We have both Eastern Comma and Question Mark butterflies here. The caterpillars of both will eat hops to the ground. I pull them off and smash them. Once you get the first wave, the second is light work. There has not been a third wave in a growing season.
Thought I'd revive this thread for 2016. My hops are in their 3rd year and are doing really well so far. I've had some Japanese beetle issues in years past but this year they seem to be nowhere to be found throughout the garden (I ain't complaining!). It's a mix of Chinook, Centennial and Cascade. The cones are already pretty sizeable- my guess is 3 weeks til harvest. Last year I got 2 rounds of cones in one season, one in early August and one in late October... go figure? Both times I wet hopped a pale ale. This year I might try and build me one of those Randal the Enamel Animal thingies out of PVC instead and try that direct "in glass" infusion from my tap for all that hoppy goodness.
