How is chlorosis treated?
Chlorosis may be treated, but not the underlying problems that produce it. Chlorosis can be treated with soil treatments, spraying applications of micronutrients to foliage, and trunk injections. The treatments that include fertilizing the soil typically take the longest to show effects, but they yield the best overall outcomes.
