Hi. Thanks to everyone for the responses to my Port Afra questions.

I have also purchased a bougainvillea pre-bonsai. And while I think I have a long term plan for the tree, I have some questions about the winter. I live in PA (zone 6) and will keep it outdoors when it is hot and sunny and bring it inside when it cools down. I have read that I should keep the tree between 50-60F over the winter. I can do this in my basement with grow lights (that’s my plan) but here come the questions:

(1) What is the benefit of the “low” 50-60f temp and is this required or just beneficial? What does this help achieve? What happens if I leave the plant in the main home at 70f all winter?

(2) Do I still give the plant light over the winter? Or Is this low temp going to induce dormancy? Generally speaking will the plant keep its leaves through the winter (Hence the need for lights)? Will it actually grow or just hang out?

(3) THE REAL QUESTION (relevant to this year): So I just got this thing in the mail about a month ago. It lost all of its leaves in the box. I over-potted it in traditions bonsai soil mix, put it in a south facing window, and gave it supplemental LED light all day long. I have gone Light on the water (so far). After a month It looks good, little buds seems to be getting bigger. But it is butt naked. No leaves. So should I keep this tree up in the 70f home with better light until it gains back some leaves? Skip the basement this year? Or do I put it in the 55F basement right now? And do I give it light in the basement? And if so should I expect growth?

I am essentially concerned about following the recommendations I have read of the internet when my guy actually needs something a little different because he just went through the USPS and is still pissed off about it.

thanks!
 
Not sure about all the things that you have read, or if that's what you are supposed to do. I keep mine in a southern exposure with additional grow lights, temps range from 65-70 degrees. They drop some leaves when they come in, but have dropped considerably less with the addition of better lights this year. A couple are blooming, so I must be doing something right. Repotting in the winter, right after being shipped probably wasn't the best thing to do, they seem to do the best repotting during the heat of the summer. If it has dropped all of it's leaves, water sparingly and give it plenty of light. Be patient, sometimes they play dead for a bit when insulted, then explode with growth. Best of luck, they are one of my favs.
 
How I handle winter up north...

Indoors under a grow light for 18 hours on thanks to a timer. A sensor set to alert me if my room drops to 65F. So a secondary heater can be turned on.

I've had this on my bench since 2015...here is what it looked like back then.

And this summer in bloom...

Mine just sit in the living room, in a southern window. No problems. Except for * mealy bugs.

Thanks. It sounds like I don’t need any special wintering plan whatsoever. Just warmth and light year round. Outside when I can, inside when I must. I guess what I was reading about 50-60F was garbage (?). I’m glad I asked. I have no experience !

when I received the plant I just slip-potted it into something bigger with bonsai soil around the existing rootball. I didn’t disturb anything (hopefully). I’ve mostly just stared at the thing.

thanks!

I personally have always thought this species a good beginners species. They thrive on neglect to a degree.

I started with no grow lights...I just became so focused on tight internodes...and this room I kept them in near the window...under a 4x4 skylight...created leggy growth. But again...that's me. Depends on what ones goal is over time. But I got tired of three steps forward and two steps back...by cutting off all winter growth over the internode space. Overall...the tree did have enough light to not drop leaves for the most part, but did shed some foliage. But it doesn't skip a bear now when I bring it inside. They really thrive under a good light. But also will survive winter without one. Just sulk a tad...at first...and get leggy.

Thanks. This is very useful. I will definitely keep mine in the sunniest warmest spot I have (inside) for the winter. Which works out, because my P. Afra would be lonely anyway.

Isn't your living room more like a sun room, from the pictures you've shown? So probably much more light than a typical living room.

Not sure what a sunroom is.
The previous owners took out the back wall from the house and made a 3*6m glass extension.

But it matters not, because the sun hardly rises here in winter :( (Only reaches 16 degrees above the horizon). No direct sun hits the plants for all but the brightest hour of the day these weeks

Did yours happen to come from Puerto Rico? I've bought several from a vendor there and they came as you describe, but came back to life after shipping fairly quickly. The trick was keeping them warm, giving some sun (or grow lights) and until they're established not letting them dry out too much. Bougainvillea love dryness but not until their roots are established.
 
Honestly...I don't know a lot about lighting. I know Judy switched to these...and I made the switch as well.


I'm leery of LED as to quality.. I had this set up of a three way clamp LED and it was horrible. My bougainvillea sulked all through winter. When it outgrew the first grow cart. So not all LED are equal. I will let another add their thoughts. This though ran on a built in timer of 12 hours..Bougainvillea need 18 hours of light. You could not plug it into a wall timer to alter the internal timer.

Agreed. I haven’t had much luck with the 3 way clamp ones either.

what type soil do you recommend? I use this for my tropicals but it’s really fine grained and I feel it holds water.

 
I use the bonsai soil mix. Depending on what size pot I have as for regular or shohin. I do use organics for my tropical.
