Winterizing a palm tree to -5 c for a Vancouver island winter

[Bill Nanaimo]

I’ve got a few 3-4 year old palm trees in the yard, I was told at that size just to throw an upside down garbage over it to protect it incase of snow, from Dec-feb it gets down to -7 or -8 for the odd day here and maybe -1to -5 for 3-4 days in a row not much longer anymore. 
im in zone 8B what do you guys to winterize yours?

I don't think you'll have much of an issue with Trachycarpus there . I would just throw a garbage can over them if they are Trachys . There's someone on the internet called ,  " Joe on Salt Spring Island " , and he could fill you in on every exotic  you could  grow  in that area , and how to protect it if necessary . 

Look for Joe on the internet  ( who lives on Salt Spring Island )  , and you'll know everything you need to know for that area of Canada . 

Good luck , and tell him Will in NC  from  the "  Hardy Palm and Subtropical Board " sent you .

I'm in 8B and I do absolutely nothing, seedlings included.  Most winters we only drop below freezing a few nights for a few hours though, so I think my winters are milder than you, but we always have the potential for cold.  I think our daytime highs in winters are also higher.

You didn't say what palm trees you have?  if they are Trachycarpus and you are in 8B you are all good and shouldn't need to do anything.

You're good if temps are as you say where you live.  It is possible small ones can spear pull below -6C  but I wouldn't worry much.

Banana Joe ( forgot the Banana part of his name )  is the man for exotics in your area . Trachys should be fine there unless young , so the trash can method is good for them , but after being in the ground a few years they shouldn't need any protection . Will
