Tropicals & Tender Perennials: When do you pitch them?, 0 by Badseed

I think my very first brug is 3 years old and was seed grown, not a cutting. I have had to cut it back several times to get it in the house for the winter. I cut it back as directed, so many nodes above the second Y. In the past it has sent out new branches and continued to bloom. This year it has taken forever to send out just a few leaves and those are not growing very fast. I did root what I cut off. Is it time to retire the original one?
