For the home gardener hops can be a fun addition to a trellis or fence. They provide great foliage, fruit, and are a good conversation piece to your garden.
Hops are often planted in form of rhizomes. These are pieces of a plants root. These rhizomes are often 4-6" long and can be planted directly into the soil or a pot. Make sure if there are shoots on the rhizomes to have them pointed upwards. If you do not plant the rhizomes right away store them in a cool place.
Hops are perennials so in the correct zone they will come back year after year. In some commercial production cases they can reach 30' tall on specialized trellis's. The hops vines are actually called bines and they have little hairs that help them grow up structures.
Hops will do well in full sun conditions and they are heavy Nitrogen eaters. They are highly susceptible to powdery mildew so it is best to be sure to water the ground and avoid getting the foliage wet. In production cases they remove the first few feet of the foliage to reduce the risk of mildew. This is called stripping.
The fruit of hops, which is what is used in making beer, can be harvested in the fall. Often times it is dried in order to preserve it until it is ready to be used.
