Planting:

Watering:

Keep soil consistently moist but not waterlogged.
Mulch around the base with pine bark or needles to retain moisture and maintain soil acidity.
Pruning:

Prune after flowering to shape the plant and remove dead or damaged branches.
Avoid heavy pruning, as azaleas set buds for the next season shortly after blooming.
