Wintering trees thread

The freezes are approaching many of us or have already come

How are you wintering your non-cold hardy trees this winter? Show off your setups be it full fledged professional status or “holy crap I forgot we’re having a cold snap throw something together now!”

I lagged on my cold frame, and had other projects, but turned out fine. Getting our first sub freezing lows for the next 10 day forecast starting tonight

I can pull the whole front and top up and over to allow rain and snow in as needed (it rained all day yesterday, so everything’s good)

Also put a temp gauge inside to monitor the difference between actual inside temps and outdoor temps on my weather app (I plan on getting 2 thermometers and having one in and one out. Soon)

Assuming your in the states, what is your USDA zone? Just curious.

Whenever I see plastic tarp, I remember that time I build my first tarp greenhouse and had to pick it up twelve doors down the street after a tiny gust of wind.
The entire thing got lost after a truly windy day. Never found it again.
My plants have been shelterless ever since.

I am afraid my non-frost hardy species (e.g., raintree, jabuticaba, bougainville, ficus) move inside around mid-october, weather dependent. Recently repotted trees might move into the shed for a few days at a time. All others will have to do outside.

I DO bring olives inside the shed for the days that are frosty. The shed is a few degrees warmer than outside, but not much. Just enough shelter to avoid the peak cold at night. The rest.. Later this week a bunch of trees will move to the ground, sheltered from wind & sun.

I have one recently collected yew that has a frost cable around the pot:

Well, my setup didn’t work. Temps were the same inside and out. Condensation froze on the plastic, lol

I got more binder clips to try to close up any gaps since I didn’t use that many initially

I’ll hopefully go to the local park and rake up a few bags of leaves to use for insulation and heat

Here, zone 8b/9a, we don't have many nights with temperatures below zero (32 F). The worst we had last year was -9°C (15.8 F) and the upper soil stayed frozen for about a week. Otherwise, it's a couple of night in a row between 0 and -4 at most.
For several years, I've used a patch in my backgarden : I dug about 15 cm (6 inches), put a liner on the soil, then cover my more fragile bonsai with Zelkova leaves. It's been enough for them to pass the winter without any damage.
