Wind Chill and plants: In order to get colder due to wind chill, the object the wind hits must have flesh and blood. Plants do not have flesh and blood, therefore it does not affect them.
However, if the wind is persistent over time, the plant will dry out some. If there is no moisture with the wind so the plant begins to dry out, giving the plant water would help it.
My husband was just sure plants would get colder due to wind chill and I don’t think I ever convinced him they wouldn’t. Plants do not get colder with wind chill - gotta have flesh and blood for that to happen.

Lack of moisture is a key ingredient in plant damage during the winter. It is good to make sure all your plants and shrubs etc. are well watered in the late fall so that they can better withstand the cold.
Once the freezing weather is in play, it is not recommended to water them though.
