My impatiens' leaves have turned a whitish/grayish color. Can you tell me what this is and what I need to buy and do to make this go away?

It sounds like they may have developed gray mold, or botrytis. Once this fungal disease starts, it will spread to the rest of the healthy plant. Botrytis thrives in humid, damp conditions with cool nights. Spores are spread by wind and splashing rain or water from one plant to another. You will need to keep some ventilation going and remove all dead and dying parts of the plant to deter the mold from growing. You can spray the plants with an approved fungicide (check the label) to keep the disease from spreading but will not stop already infected plants.
