Most of the brugs, will start to bloom early summer. You just need to get them out in the sun as soon as your frost is gone, and they need lots of fertilizer. I use miracle grow, and I double the strength for the brugs, I also use it at least once a week, once they start growing.
Also, most of us that bring them in for the winter, will take cuttings from the top of the plant, root them for next year, then let the plant go dormant, don't water them much, then when it gets warm, get them outside water them, and watch them grow.
Hope this helps?
