Luckily among one hundred palms I have in the ground at my house in the province of Cremona, only three species have been damaged: a little Trithrinax acanthocoma and a Livistona australis are fried (but it was a predictable event), and some Chamaerops humilis (common form) have serioulsy damaged leaves (but some new green ones are emerging). Anyway I am happy as the rest of the palms are ok, and I am sure of that as I have registered many days with temperatures above 20°C under the sun (the majority of my palms are in the southern part of the garden).
Many palms have been protected only with huts made of non woven fabric for plants; I have used heating cables only for some Butias, and I have rolled them only in the trunk and in the central leaves.
Here we go:
