Puterbaugh Farms has recently started a blog about the hop-growing business. It’s very interesting if you grow hops, with photos of the bines, what powdery mildew looks like, and how to tell that your burrs are turning into cones.
I bought from Hops Direct last year, and was mostly pleased. The experience was a bit rocky due to the shortage-induced chaos, but they made things right rather quickly once the problem was noticed.
