Diagnosing horticultural plant problems is similar to being a detective. The investigator must collect and evaluate all clues, keep good notes, establish the facts, and synthesize them into a conclusion. Take adequate representative samples and keep collected samples in good condition. Have an open mind and don't assume that the current problem is the same as another similar one. Damage may be more severe when multiple causal agents or stresses are involved. Clues to the problem are either signs or symptoms.
