I initially started with just 3. Hallertau, Northern Brewer, and Cascade. Then a month later before the wife knew what hit her, I was planting Mt Hood, Centennial, EKG, and Chinook. I harvested a great amount from the Chinook and moderate from the Centennial. The Cascade ended up getting stunted so I got a bunch of midget hops. Nothing else really produced hops but I let them get as big as they wanted to let the roots grow. Next year I will be relocating the hop garden and adding Saaz and Styrian Goldings. You just have to find out what grows well in your area and go from there.
