The new growth on my holly bushes is all black it looks burnt what is wrong?

The blackened new growth on your holly bushes may indicate a fungal infection, such as leaf blight or a similar disease, which can cause the leaves to appear scorched. It could also be a sign of environmental stress, such as excessive heat, drought, or root damage. Inspect the plants for additional symptoms, and consider improving air circulation, adjusting watering practices, or applying a fungicide if necessary. If the problem persists, consulting a local extension service or horticulturist may provide more specific guidance.
