So I live in NY and bring in my plumies end of October. They have been in a room with a humidifier and some gentle air circulation, a grow light, at a constant 67-72 temp. They had some inflos that have continued to push out flowers, and now all are spent. I had decreased watering to once every other week just make sure they didn't completely dry out. I originally intended to just winterize them in my house. However, leaf buds are continuing to form and push out branches at the inflos. At this point, should I just continue to do what I'm doing and maybe they just won't go dormant this year?? Some older leaves from summer have fallen off but it is still quite hardy looking and as I mentioned new growth is continuing.

I suggest you add an Ambien dissolved into a gallon of water & turn off the grow lights

If it were mine, I would just continue to let it go dormant while indoors. Those new leaves and inflos are at most quite weak growth. Might as well save all those energy for next season, and let the plant rest right now. To keep those leaves and inflos going will require watering, and with temps already colder and light levels not optimal at this time of the year, you will be risking fungal issues. Better to just keep it dry and let it sleep the winter season away.

It took me awhile to realize before , why am I forcing this tropical plant to stay alive in winter, when it wants warmer, and more direct sun conditions to thrive better. I am for sure not going to be able to provide indoors the 80F to 90F temps that it likes at this time of the year. So I would prefer to let it go dormant, anyways, it is not dead at that point, just resting and bidding its time till late Spring returns again.

It is your choice of course, decision always yours.

Thanks for the advice. I was still keeping it alive as I was waiting for the rest of the bloom to occur. I think the last 2 flowers in the inflo bloomed finally, so maybe now I will let it go dormant.
