  Some souce claimed that Marumi Kumquat can withstand 10F and start to lose leaves at 0F without injury. Is it a myth?

A full-blooded kumquat is going to die deader than a door nail at 0 degrees F if not protected from the zero degrees F. My Thomasville citrangequat dies down to the ground at 7 degrees F. Of course it depends on how long your tree is exposed to temps below 32 degrees F. If itís below freezing for days at a time, you will see severe die back of your trees possibly loosing the entire tree. Even with wind breaks and wrapping the tree in cloth and burying it 6 feet deep in leaves, Iíve lost citranges 8 feet high to zero degrees during ďthe polar vortexes ď we had several years ago. Iíve seen 10 ft tall citranges cut in half or to the ground after a warm February followed by a 14 degree night in March after the trees started to put out just a centimeter of new growth, and these were trees protected in a high tunnel with water barrels next to each tree. Unprotected kumquat in zone 7 in the southeast USA gonna die.
