What Causes Azaleas to Die

Two fungal diseases can cause azalea branch dieback: Botryosphaeria and Phytophthora. There is no practical chemical treatment for either disease, although fungicides may prevent the disease from spreading to other plants.

How do you revive a dying azalea?

If your azalea is dying, you need to apply a fish emulsion to revitalize the plant. Spread a compost over the root system and keep the soil moist with mulch. If you don’t water and mulch azaleas during hot dry days, the leaves will scorch and the plant will begin to fade.

Can I bring my azalea back to life?

Remove damaged azalea branches by cutting them close to ground level with clean, sanitized pruners. Before pruning, check to see if the damage to branches is deep or surface level by scraping back some bark first; if you see green growth after removing the bark, this means that the branch may revive in time.
