Any ideas about a palm tree and some frost

Hi everyone, can anyone tell me if these palm trees will need covering for winter ❄️ well mainly frost Or will they be ok?

 

Looks like a very young canary date palm.
Depends on the type of winter we get, but I'd say anything below minus 3 could be a problem.

 

Tend to go brown after a cold winter

 

Yeah ok I think I’ll cover them just to be sure thank you for the advice

 

iv grown loads of them brown ones on the past few go yellow then brown trust me iv gota garden full of them if you want any let me no
