even a cutting can put on eight feet of new growth in a season.

sunlight, sunlight, sunlight, a nice layer of mulch to keep the soil moist, regular morning waterings (better two deep ones a week than a spritz every day)

that's about it. and yes, once you get it established- you'll spend the rest of your life trying to contain it.

make sure that your fence is strong enough top support it - Longwood Gardens has them on 2" conduit pipe and 4x4" posts, but they're also 80 years old, and have trunks like trees:)
