Thanks! They are quite big, so big I have questioned the term "dwarf" although I have seen Orinocos in the area that are larger. I don't have an exact measurement but taller than me for certain, maybe 9 feet tall? The stems are pretty thick on the largest ones - they are growing in a close cluster of about 6 large plants and a few young ones as well as a lot of little pups so well established.
The forecast is for 33 but last year that was the forecast and they all died to the ground because here we had a hard frost of about 28. But I didn't do anything to them last year. Currently I have piled up mulch around them at the ground stems, I was thinking of wrapping cardboard too. The trash bags on top of that is a great idea, thanks
