Rhododendron PJM Group Characteristics
Rhododendron PJM Group are evergreen shrubs with large pink or lavender flowers. Proper maintenance is required to keep Rhododendrons healthy and blooming. Some shade is necessary as the leaves may scorch in direct afternoon sun. Sun dappled shade or morning sun with afternoon shade is preferred. While soils should be consistently moist, good drainage is essential, especially in heavy clay. The roots are shallow, so landscaping should not be done at the base of these shrubs. Mulch around the base to help retain consistent soil moisture and to protect the roots from harsh winters. Acidify soils as necessary.
Rhododendron PJM Group are susceptible to a multitude of insect or disease blights, though they should rarely be an issue unless improperly cared for. Insecticides and anti-fungals may help. Root rot is common in overly saturated soils. Chlorosis, evident by the yellowing of the leaves, is an indication that the soils has too high of a pH. This should be resolved immediately as chlorosis can be fatal.
