The resistance of acacia species to cold seems, in my limited
experience, to be much affected by wind chill factors. I live in the
Midi region of France, about 60 miles from the Mediterranean Sea and
some 40 miles South-east of Toulouse. Last winter all the acacias in the
area where I live were killed to the ground by a frost of no worse than
-5 degrees Centigrade but which was accompanied by a strong wind.
Similar trees in the Toulouse area where the temperature fell to -10
degrees suffered little or no damage.This area is not subject to the
same cold Tramontane wind as we are. The same differences were true for
several species of Australasian origin. Happily most of the plants have
re-sprouted very well and should make good speciments in a year or so if
spared by future winters. I seem to remember someone mentioning a
spray-on product that prevents drying out of plants. Does this have any
protective effect against the kind of frost damage that I experienced
and if so what is it called?
