Lee Ann, my brugs bloom nearly year-round here in Florida. Sometimes they slow down blooming through January and February if we get a few cold fronts. Most of the year I get a flush of blooms about every month.
So, I agree with the others, if you pot it up, take it indoors and see if you can keep it growing all winter, even if it just keeps its leaves and grows slowly that will give it a head start on blooming next year. Got a sunny window in the house?
Take it outside as soon as the nights are above about 50deg. F Be sure to keep it somewhere really warm when it is outdoors like the south side of a fence or the house to keep it warmer at night and longer into the fall as well. Even the occasional cool night will slow it down. Tropical divas are very temperature sensitive!
Compost is not nearly nutrient-rich enough to grow brugs although they love it as a soil amendment to help hold the nutrients from fertilizer. It releases the small amount of nutrients it has very slowly as well. You need to really feed those puppies to get them to put out all those huge, fleshy flowers! I give mine a sustained release pelleted fertilizer like Nutricote 20-7-10 in March and again at the end of May and also add a soluble fert with high numbers like a 20-20-20 every second week when the weather is hot. The more you feed it . . . the more it will grow and bloom. I've also added a douse of Epsom salts occasionally. I spray it on my orchids, and a couple of my big potted brugs are in the pool cage shading the orchids, so they get sprayed with it too. Extra magnesium really helps with chlorophyll production. Can't hurt!
Add that to abundant water and you will have a big, lusty blooming brug. Here's a tall pink NOID that went straight up to over 7ft. tall before it made a Y and started blooming. Depending upon where the cutting you got came from, (above or below the first Y) they might do this, or they might branch and start blooming when they're quite small.
