Container question

flower patch

I have an Acer in a pot due to the high winds this week, I wonder should you water as if for sunny weather (every other day) or just once a week? 
I am not sure how much moisture they lose through the leaf?

I  water mine every day but they are large and have been in the pots for at least 6 years.
