25 yr old shrubbery rhododendron surface roots need to be covered with dirt?

Whitley County Kentucky

Expert Response

I am not sure I understand the question. Has the area eroded leading to the roots being exposed? Are you asking -There are roots are on the surface of the soil and you want to do something to cover them?  I would not cover the roots. They are on the surface and have done well in the site. When roots are on the surface it means the plant has adjusted to low oxygen levels in soil. Any disruption will probably cause some sort of stress that could lead to Phytophthora root rot and loss of the planting.
