A good time to fertilize trees in most Southern temperate climates is from fall to mid-spring.  At these times the tree’s roots take the nutrients from the soil and apply them to important health-promoting functions such as root development and disease resistance, rather than simply putting out new growth.

During the growing season, fertilizing can help a tree overcome mineral deficiencies and fight off infections.  If you are fertilizing in mid- to late summer, avoid formulations high in nitrogen as this will just promote weak, new growth that may be easily damaged in the winter.
