Leeks & green Onions

Is it ok to overwinter these two items, living in Colorado at 5k feet Sone 5 I believe. If not I will have to harvest TODAY:)

Thank You Kindly,

Leeks can survive frost and can retain quality even if temperatures drop as low as 20 F. Below this they may lose quality. Onions are similar, see this article for more:
