Gray to tan spots appear on pansy flower petals following infection. Leaves and stems of young shoots wilt and die, turning brown to black color. Pansy, peony, petunia and geranium are susceptible. Winter, during wet periods and unfavorable growing conditions.
Gray mold is an airborne fungus that attacks flowers and damaged or dying tissue.
Pansy flower petals discolor and rot. Stems and leaves yellow, then darken, turning slimy. If allowed to spread, the disease will damage the plant. If fertilization is done at the time of planting and supplemented once a month, the plant stress will be less. Remove dead lower leaves so the disease has no food source.
