Depth of roots for Rose of Sharon?
Does anyone know how deep rooted these shrubs are? I'm needing to put one in the ground in my Mom's yard, but the best spot is near the field lines for her septic system. I'm thinking that the guy who installed it said it would be fine to plant small trees near by, so that sounds like it would be o.k., but would really hate to mess it up with roots.
Thanks in advance,
