Impatiens

Question

The impatiens’ leaves are turning grayish and are falling off or being eaten by some insect. What can I do?

Answer 1

This could be attributed to Botrytis blight, also know as gray mold, which is a fungal disease. Since it spreads easily, it’s best to discard the entire plant. OR your plants may be affected by spider mites. White flecks or webbing on the underside of the leaves are good indications of spider mites. The leaves of impatiens will begin to look gray or bronze in color as more damage is done. A heavy infestation will cause leaves to die and drop off. You can use neem oil or insecticidal oil to kill spider mites.
