My husband has a bromeliad that was in bloom when he got it. The blooms faded over a year ago, and it put up a strong new generation of growth. However, it has not re-bloomed.

I've read you can force a bromeliad to bloom by putting it in a bag with a ripe apple, but my husband does not want to force it in case it is not ready to produce a new generation of 'pups' after the blooming.

Is there anything culturally we should be doing to encourage blooming? Are they generally easy to re-bloom indoors on a windowsill?
