It is hops growing 101 to do a ceremonial moroccan rain/sex dance on your birthday in full view of the hops. Failing to do this will royally piss off nearly every variety but cascade.
You also have to leave tootsie rolls for the brew fairies all winter long.(usually 1 and a half tootsie rolls per hop plant)
Then again you also want to make sure not to pour gasoline all over your hops and flick lit matches at them......you might also consider not cutting the bines down halfway through the summer in a drunken rage.
Aside from that, hops like LOTS of water and LOTS of fertilizer. Cascade will always put other types to shame.
