Clammy azalea thrives in moist, acidic, well-draining soil in partial shade, making it ideal for woodland garden borders. Water consistently to keep the root zone evenly moist, especially during dry spells, and mulch heavily to retain moisture. Avoid alkaline soils and full afternoon sun, which can cause leaf scorch.
