After doing a lot of searching online, I am not finding a good reliable answer to how cold hardy bergamot is. I’ve seen on Dave’s Garden that it’s hardy to 35 degrees F, and somewhere else 30 degrees F, and that they are one of the least cold hardy citrus and only grow well in the Mediterranean. I’ve also seen a lot of discrepancies about whether or not it is genetically citrus aurantium of variety bergamia, or part lemon of lime. I thought aurantium sour orange is supposed to be cold hardy. Ilya says his is in a pot, so I’m assuming bergamot can’t handle freezing temps well. I was planning on planting mine ( on flying dragon rootstock) outside one day and protecting it with a cold frame with space heater like I do my satsumas, but if it cannot survive 25 degrees F, I’ll have to bring it in the house in winter. I look forward to the expert opinions and answers to follow. Thanks in advance!
