Plant Health Factors
Biotic Factors
Fungal pathogens like Botrytis cinerea can cause the inner parts of barberry bushes to die by inducing disease. Bacterial pathogens, insects, mites, and nematodes can also contribute to the decline of plant health.
Abiotic Factors
Improper watering practices, such as overwatering, can result in waterlogging and root rot, leading to the death of the inner bush. Soil conditions, sunlight exposure, nutrient deficiencies, and pollution can also affect the overall health of the barberry bush.
