It is planted too close to the corner of the house. It is a large plant that could easily fill the entire space shown, and more. I would cut the cantilevered portion off entirely, and try to relocate the root clump to the center of the space. If the relocation is unsuccessful, start over with a new, small plant that is planted at least 3' to 3 1/2' away from the house wall. Then keep it trimmed to fit the space.
