Hi Edmar,
I have an Opuntia since 10 years now, and he made it every winter with no problem and no protection, as well for the Yucca filimentosa. I tried to protect in the past musa basjoo, but never had good result here. The plant started from the roots in the spring. And make to much time to grown to a good dimension 😥 ...So now i cut the foliage after frost and dig it out and put it in a pot and i bring it Inside home in a cool place.
Mike in Montréal had good result with the Basjoo, but he s located in a warmer zone than here. I think to protect it again this year, but the problem i had is it was to humid Inside the protection and that result to fungus problems that killed the pseudo-trunck.

Does everyone have a good technique for that with adding no heat 😕 ...

Hi Beny!
what I plan to do is wrap the trunk in many layers of protection: burlap, frost cloth and R8 insulation ( http://www.rona.ca/en/insulation-04125311--1) also for the ground I will put some type of plastic with frost cloth so it will seal the area when I put my polystyrene box and finally the special ingredient: silica gel! it will be my experiment for absorbing the excess moisture, I already tried it in a smaller scale(to absorb moisture from bulbs) it's very effective, this time I will put it to the test on a bigger scale so I will need more: 20 to 30 grams should do the trick, I already purchased a bag full of 10g packets it's not expensive.

Good idea, let us know about that experiment. Maybe i will try to protect again my Basjoo..will let you know what kind of protection i will try 😉 ...
