How to trim African Iris?
These are over 2 yrs old, and I have only gotten 1 or 2 flowers. What do I need to do to make them bloom more? How do I go about trimming them, and when is the best time?

They don't, usually, need fertilization, and will never need trimming of foliage. You can trim the bloom and bloom stalk, but trimming leaves will not be advised unless you are dividing them.
They can have a lack of blooms due to over fertile soils, too much, or too little water, and too little, or too much sun.
