Greetings! I recently purchased a Salix integra 'Hakuro-nishik' for a cove in my front yard. It in centered in a corner between my sidewalk and my house. I live in zone 7b. The tree is 5'-7' away from the foundation. It is about 30' from any water lines and about 80' from out septic tank (lines are in opposite direction from tree). Any concerns with the tree. I understand it is grafted on standard willow stock. Also, it is in partial sun.

Any help is greatly appreciated.
