Rhododendron 'English Roseum' Characteristics
Rhododendrons are very popular shrubs in the Pittsburgh area. The large flowers and shade tolerance make them showy additions in areas where other flowering plants might struggle. Light morning sun is acceptable, but strong afternoon sun may cause scorch. These shrubs survive best when guarded from strong winds. It is important to not plant near walnut, butternuts, pecan, or hickory trees as they excrete a substance that is toxic to Rhododendron. The root system of these shrubs is shallow, so avoid landscaping at the base. Mulching at the base is advised to help to retain a consistent soil moisture.
Rhododendrons can be vulnerable to many insect or disease issues. This can often be cured by pesticides and anit-fungals. However, if planted in the correct location and cared for properly, these issues should not be life threatening. Root rot is common in overly saturated soils. Chlorosis, the yellowing of the leaves, can happen in soil with too high of a pH. Chlorosis should be immediately attended to as this can be fatal.
