Azalea ‘Delaware White’ prefers acidic, fertile, medium moisture, well drained soils in part shade. Pruning is not required, except for the clipping of dead flowers to avoid self seeding and ugly large dead flowers. Late frosts may kill new flower buds, so early spring and late winter protection is recommended.

Azalea 'Delaware White' Characteristics

Azalea 'Delaware White' are slow-growing evergreen shrubs that are populated by white flowers in spring. Some maintenance and proper locations are required for these shrubs to reach full potential. 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. It is recommended to shield from frosts when buds begin to show.

Azalea 'Delaware White' 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.
