I have been gathering rose hips and have an order of fresh acorns on the way for Secret. Can anyone tell me what they do with theirs to make them last the longest.

The rose hips-should they be kept in the refrigerator, should they be left out to dry or put in the freezer?

and the acorns-I know they can be kept in the freezer, but should they be left out to turn brown first or put them in the freezer right away?

thanks!!
