Expert Response
Your tree most likely has spider mites. Symptoms are
white or yellow 'polka dots,' The dots are usually the size of a pin head that can spread to give the leaves a whitish look. Spider mites suck the juices from leaf cells, causing leaves to bleach out. One treatment for these is spraying with a jet of water on the underside, another is insecticidal soap and a third is Neem oil. Be sure to use the pesticides exactly according to the label to avoid leaf damage. Be sure the plant is adequately water before us also. Spider mites are very common in greenhouse situations and can float on breezes to new plants.
