Abiotic problems are caused by non-living agents such as weather extremes, poor soil conditions, and drought. Biotic problems are caused by living agents such as insects, and pathogens such as fungi and bacteria. Effectively diagnosing abiotic disorders of trees and shrubs involves:
- discovering the underlying cause(s) of the problem
- understanding the damage that has or continues to occur, and
- recognizing the plant symptoms that are characteristic for the damage.
The following links describe causes, damage, and symptoms of common abiotic problems.
