What is wrong with my Escallonia hedge plant?

Did the foliage of your Escallonia wilt and turn yellow or brown?

Are there any purple to black spots, often with grey-white centers on your Escallonia?

Are the leaves of your Escallonia small, discolored, or drop early, or are clusters of honey-colored mushrooms sprouting at the base of the Escallonia?

Are the leaves of your Escallonia yellow, or are the branches, and leaves covered with small bumps?

The cause and exact solution of Escallonia dieback is not known. Escallonia dieback causes the foliage of Escallonia 'Fradesii' to wilt and turns yellow or brown. Branches or even the entire plant can die. Provide a good growing environment for your Escallonia and appropriate cultural care.

Escallonia leaf spot is a fungal disease of Escallonia species, causing spotting on the leaves followed by defoliation. It was only first noticed a few years ago but has since spread rapidly. Severely affected Escallonia plants can be reduced to bare branches. Dispose of affected leaves and any that have already fallen as a result of the disease. Fungicide application may be necessary to prevent re-infection. The fungicide tebuconazole with trifloxystrobin is recommended for the control of leaf spots on ornamental plants.

Armillaria root rot is a fungal disease that cannot be effectively controlled once it has become established. Diseased or dead plants should be uprooted and removed. Planting resistant rootstocks is the most effective method of preventing the disease.

Soft scales are known to attack Escallonia. Scrape off minor infestations with your fingernail. Prune out badly infested growth, or use a soft brush and soapy water to gently scrub the scales off the stems. Control scales by spraying insecticidal oil during the growing season.

Mineral deficiencies can cause tip chlorosis or necrosis or cause foliage to discolor, fade, distort, or become spotted, sometimes in a characteristic pattern that can be recognized to identify the cause. When nutrient deficiencies occur, nitrogen and iron are the most commonly seen deficiencies. Apply only the mineral found to be deficient. Excess nutrients, on the other hand, cause symptoms like leaf tip dieback, marginal leaf chlorosis, necrosis (or burn), branch dieback, and pest problems. In this case, you should provide good drainage, and use good practices during fertilization and irrigation.
