When is the best time to fertilize my Blue iris?

Feedback

The ideal time to fertilize a Blue iris is in the late winter to early spring. During that time, your Blue iris will be exiting its dormant phase and entering a phase of active growth. Fertilization at this time allows the plant to get off to a great start for the season by encouraging healthy growth. While it is generally most advantageous to fertilize a Blue iris during the early spring, it is also permissible to fertilize a Blue iris during the fall too. However, summer and winter remain the seasons in which it is not a good idea to feed a Blue iris.
