When Winter Arrives

So when winter arrives I had an idea and not sure if it will work? What if I planted my Sarrs in a styrofoam cooler and then placed the lid on it during the winter. Would this be enough insulation so they could stay outside all winter?

The Temperature would reach ambient within a few hours, insulation just delays this. Plus mould would be a risk in a small enclosed space, especially if the temperatures went a bit above freezing.

How is mulching successful then? Wouldn't this method simulate mulching? Minus the mold issue.
 
Mulching adds layers to the soil, the soil being a huuuge bank of thermal mass. So, if you add 2feet of mulch, you could be at the same temperature as 2feet down into the soil. Yes, it would be colder under the mulch than if you were 2 feet into the soil, but I think this adds a new view of mulch.

For easy math, I'd say look at what your region has as "the frost line" when talking about building codes and foundations. Then, add that many inches of mulch to your plants during the winter months.

I too agree that a cooler would do more harm than good, and mulch is the way to go.

If you added a 1 ft layer of malleable styrofoam, that may be enough.. but I dont think that's what you meant with a cooler.

If your collection is small, maybe the fridge is a better space for you.

Do you have access to a garage? I stick mine in the back of the garage. Only suffered 1 loss last winter and that's because I let an unestablished VFT completely dry out.

I tried my garage and lost my whole collection to frost. I might try a clear tote with water in it and a heating mat.

I guess here in Quebec, if I did not have my half heated garage (4C) I would not have the choice but to buy a fridge for my plants. I saw some nice cooler for wine with a glass door, and I would probably go that route. The problem is that when storing them in the fridge, if you have many you have no choice but to unpot them.
