Ok folks, I did a quick search and turned up empty; probably because this is a little specific.
Two years in a row, my Centennial has started strong and then died off. Completely. I just bought a Medusa, and it died off in less than a month (maybe over-watered?). The Cascade does Ok, but I didn't get to harvest it last year, just cut it off after the cones went full dry. The Eroica seems to get about 12-15' up and then starts to die off. The Old Mission and the Chinook go gangbusters. The Shaddock was great, and then it just didn't come back this year. The new Comet I have high hopes for (1st year). I have tried and failed at Zeus, Nugget, Cluster and Crystal (and a previous Cascade). I have several books, lots of articles, I check in with the other hop growers; I am at a loss.
The hops get hours of sun. I don't let the soil dry out too badly, I look at all the plants to see how they are doing since the weather is inconsistent at best here in SoCal by the beach. I do light fertilizer once a month, because we also mulch our green waste and spread that throughout the garden. Most of my other plants do amazing-dragonfruit, grapes, figs, avocados, lemons, pomelos, sages, passionfruit, cacti. By all accounts, I have the greenest thumb in my family. Yet, I keep losing my hops, which is a weed, and should just grow and dominate the garden. Any suggestions based upon what I have detailed?
