How do you get your aechmea bromeliad to bloom you have 3 different plants that have never bloomed over a period of a couple yearshow can you make it bloom?

Young bromeliads will not bloom. It takes thee or four years at least for the plant to be mature enough to bloom. If your bromeliad was blooming when you got it, it will not bloom again...ever...it will produce an offset that you can pot on it's own when it's about 1/3 to 1/2 the size of the mother plant.
