Good Idea MaryMcP, you can also set a fan out to keep the air going so no frost will set.. but a tree 2 years old shouldnt have a problem here,, at that age I'm guessing its around 10 to 13 foot tall. "If" we have a real bad freeze it might loose some of it leafs but it wont die unless we have a LONG Continues Freeze.. and I mean for 48 to 72 hours straight..
you should be Ok

I've been growing some here in pots for a couple or years and can tell you they'll be fine with anything above 28 or so. They'll burn under 32 but they will recover. So if it burns, don't let the burning scare you too much. As long as it's just to the foliage it'll be fine. If it appears that it's to any of the hardwood then I'd be more concerned. And if it get's colder then 28, try and cover as much of the trunk and center of the tree as you can. There's a Royal Poinciana that's been at the U of A since the 1970's and it's gone through some rough winter's, even in it's protected location. After December of 2003 the 25' tree was 70% burnt, but the last I saw of it, it was recover from the trunk.

Now I'm able to see the pictures. Nice pictures. Do you have any of the whole tree?

Thanks,

more pictures from the yard....I spent a week in Rocky Point mid October and saw unbelievable blooming Royal Poincianas that were about 25' tall!

How big was your Royal when you first bought it? Yours is absoulutely beautiful!

Wonderful photos -- very artistic, especially the first group!

Thank you, the trees leaf pattern was so uniform and artistic all I did was point, shoot and crop, the texture of these leaves is wonderful also, kind of like running your hands across very delicate leather.....the plant was about 2 feet tall in a 5 gallon container when I bought it, I built a tent over it last winter and let Christmas lights burn inside during colder nights. This year I will try to build a shelter and run some spot lights for extra warmth.

Very nice. The one I just bought looks like a stick in comparison! Tera said we're approaching dormancy time and that it should be much happier in time now it's no longer in a pot. I'm just hoping it will sprout branches, etc. in the spring. Yours is very lush and will look even better when taller and more canopy-like.

I recently bought seeds of this tree, and had one sprout yesterday, so figured i needed to start more research on this tree as i'll need to know more for its care. I have read about overwintering trees somewhere on another forum here on gardenweb. It said to wrap a clean unused towel around the trunk, then fill leaves up to the lowest branch, and then water down till all leaves are wetted. I would imagine if you make a chicken-wire bin to hold the leaves in, and then surround in seran wrap that will hold the moisture in more, and also the warm air, as i think that is supposed to decompose over the winter, but i thought it had to be somewhat warm to decompose? anyways i think i might try this, i dont remember where i saw it, but i can search now as im sure its a good method, i read good reviews from it while i was reading.

I know the posts above were a long time ago but this is all still relevant. It is 2023 and I have 5 Royal Poincianas that were grown from seeds. I let them grow in pots for about a year and then transplanted them in the spring. There was one more frost and a couple of the small ones appeared to be completely dead but I kept watering them, just in case and they finally started to bud way after the others. I used dead leaves, oranges that fell from our trees, and mulch when I planted them and they all definitely grew like crazy over the last year. 3 of the bigger ones that did not get the frost damage are now over 7 feet tall. I am expecting them to double in size this summer. 2022-2023 was a particularly cold winter with tons of rainfall and then following with lots of cold days. I am in the horse property area in Gilbert and when it says it is going to be 36, it will likely freeze. So I spent time putting on and taking off cold protection all winter. I would guess that they spent around 20 days total protected. I used some various sized freeze cloth bags with drawstrings at the bottom (Don't buy on Amazon. Home Depot has them on their app for a lot less but you have to order them as they are not in the store). I also ran some mini incandescent christmas lights around the base and on a few, around the trees as well. I took a 4x12 painters drop cloth and wrapped the base of each. It sound tedious, but I got into a rythm and was able to deploy these quickly once I got used to the routine. The reason for the Dunn-Edwards painters drop cloth is that they shed water when it rains and they are extremely heavy so they won't blow away in the wind. This all worked very well and only the very ends of the branches got freeze burned. Thought I would share since I had research a lot and ultimately came up with the best method in my opinion. I did way too much work on these just to let them die over the winter. The plan next winter when they are larger and have thicker trunks is to just use the larger C sized incandescent bulbs wrapped around their trunks and I won't worry about the small branches. As they get larger, you don't have to worry about the cold as much unless there is a sustained freeze for 24 hours or more.
