Planting & Care

Plant your Sunglow Azalea in rich, acidic soil amended with organic matter, ensuring the root ball sits level with the ground surface. Water immediately after planting and maintain consistently moist soil throughout the growing season, taking care not to allow waterlogged conditions. Apply 2 to 3 inches of mulch around the base to regulate soil temperature and moisture retention. In early spring before growth begins, feed with an acid-loving plant fertilizer and prune after flowering to remove crossing branches, dead wood, and spent flower clusters, which encourages bushier growth and future blooming.
