The plants themselves are as thorny as it gets, so I have to be very careful taking Boy #1 over there. I've got 5 brambles growing in a 2.5 x 16 area up against the northeast side of the house, where they get sun from early morning to around 1:30 pm. The brambles are planted in unimproved clay soil, covered with six to eight inches of leaves and pine needles I picked up from my neighbors. They're right by a water spigot, so I just laid down a soaker-hose on a timer to irrigate them, but most of the time they don't need it.
As the primary canes grow I tie them to t-posts/sturdy stakes, and try to keep them pruned to no taller than five feet. I also have to prune occasionally to keep them from snagging me when I mow the grass in that area. After they're finished fruiting, I just cut out the dead canes to make room for the new ones. Kiowa seems to bloom a little bit later than the wild blackberries that grow in our area, but they're huge and delicious, and well worth the occasional thorn.
