Answer 1

This depends on the age, and stage of the trees life. Generally, when the tree is less than 5 years old, the fertilizer will be high nitrogen. As the tree ages, the ratio of NPK will change throughout the season. Potassium and phosphorus are used most during fruiting and flowering. Usually, if you use a citrus fertilizer, they will be blended to suit most any citrus tree at most any time.
