It would appear that low temperatures will kill off the fronds of Dicksonia antarctica.
Having said earlier that we never had problems with Dymo Tape pealing off plastic labels I am now having to admit I have had a serious set back. I have spent a considerable amount of time (and money) producing 156 plant labels on the new black Tee shaped plastic labels to find a significant number of the names are coming away after a short time.
My theory is the Tee labels are of not polystyrene as were all our older plastic labels, where the Dymo stayed on for many years. The Tee ones are polypropylene, which must resist the adhesive. I have been using the same Dymo tapes on normal tie on labels at the same time as the Tee ones, so I don’t think there is a problem with the tapes as they seem to stick well to them.
