Bouganvillea - small flowers

[Bonsai_hope]

It’s not a huge issue for me because about 3/4 of our year it is single digit humidity.

I’ve been growing bougainvillea as container plants in a humid 8B environment for a number of years and have never dealt with the rot issue. They remain outdoors until the forecast is 40 Fahrenheit or less when I move them into an equally humid (70% to 95%) greenhouse. I trim interior branches to foster air flow. They grow in the ground in South Florida. Is this a real problem?

It has been almost a year, the top produced a new leader that became almost the same size as the trunk that was cut, and no healing to speak of on the wound.
There was damage to branches on top, so I cut it back for photo, it needs a new chop site. The bottom wound did not close much, more on one side, so I need to scrape that.
I will save that basal shoot in case the chop does the same thing as the last time.

The dwarf seems more difficult to style. We will see long term.

I went to cut back to the first upper branch but there was discoloration inside, so I cut lower and lower, wiping the pruners with sterilizer between cuts until no more staining, then then put fungicide on and waited a bit, then cut another inch.
Put the stems in regular trash because some spores can last several years.
I wonder if these tiny roots off the side are a sign of disease, so I will pull them off after doing a soil drench with something that may help roots.
So I am left with this. I think it needs to go in the ground in the front yard if I keep it.
