limiting outward growth of Oldhamii?
Hello, I have oldhamii planted on top of my retaining wall. It has about 7 feet of space laterally but only about 2 feet of space to the edge of the retaining wall and about 2 feet of space to the neighbor's fence. Can I control the outward growth of this bamboo so it doesn't break apart the wall or the fence? Does it just involve breaking off new culms that head in that direction? Or do I need to take those newly planted bamboos out of the ground and replant elsewhere?
