I'm definitely with Estación on that! Oh please don't cut the canes. I have a couple of dendrobium that want to sprawl everywhere, but I don't have the available real estate they want to take up. My exuberant growers are resigned to knowing they will be staked, tied, etc., even though that's not my normal style. I'm more of an unclipped hedge kind of grower. But better to be restrained than have your wings clipped.
