When it comes to success growing Rhododendrons, a little good advice goes a long way. When planted right and in the right spot, Rhododendrons are very easy to grow and care for.
Rhododendrons thrive in a moist but well-drained acidic soil that is rich in organic matter and part shade; preferable morning sun with afternoon shade or heavily filtered sun. All day dappled shade is fine as well. Keep in mind that whether growing in the ground or in containers, constantly soggy or wet soil is problematic for Rhododendrons, and most other plants for that matter. Some soils, such as heavy clay, quick-draining sand, or otherwise poor soils, might need to be amended to provide sufficient nutrients, better soil drainage, and/or moisture retention. In containers, select a pot with a drainage hole(s) and use a 50/50 blend of professional potting mix and potting soil. Avoid using any native soil in pots. Feed Rhododendrons after they bloom with an acid-loving formula such as an
