A common disease caused by a mold is botrytis. This fungus specifically likes to attack flowers and fruits but will first infect dead parts of the plant. Botrytis is identifiable by its fluffy appearance and looks a lot like bread mold. Make sure to remove infected, dead parts of plants ASAP after diagnosis. Also, decreasing moisture and increasing airflow by pruning and/or deadheading reduces botrytis’ damaging effects.
