Its getting colder here; Im just being curious about how you all protect your trees from freezing temperatures?

Most trees stay outside for me, dug in or put in bigger pots for example.

Some of my trees (the winterresistant trees like Juniper) and some trees are staying in a greenhouse in the winter.

When it's getting really cold like it's predicted for next week (about -15 degrees at night) I'll place my trees that are not in a greenhouse near the wall of my house, because the house radiates warmth.

That is some neat info Youri, I never thought about how the house radiates heat at night. Makes sense though - why the house stays warm at night.

I am looking forward to learning a lot in this topic. I will use the knowledge and ya'll's experience next winter when I have trees in Missouri.

Hi guys and girls,
This is how my collection is spending the winter. The mini greenhouse has my white pine inside with the back unzipped. pine needles dry out quickly when left in the wind during winter. I left the back unzipped so air could still circulate.
I have rooted willow and hydrangea cuttings in my unheated garage...I'm still not convinced they will all make it. My Manitoba maple is also there.
The trees I had last year spent the winter covered with snow on my deck. I lost one tree. It was an azalea that I got in late november from home depot...I shoulda known.

So, those plastic mini greenhouses work pretty good? I was thinking about getting on myself for next winter.

It seems to work fine. If you do get one, turn in around facing a fence or something and leave it unzipped during the winter.That will let air circulate but will keep the trees out of the wind. Pine needles turn brown if left in the winter wind, so mine is in there.
