Should I cover my small rosemary plant at night?

Question

It gets down to 10C or 50F, I was wondering if its a good idea to cover the plant with transparent bag or something at night. It is potted, but I don't want to bring it inside until Winter. It is about 6 inches in height.

Answer 1

I have rosemary that does just great in the winter where it gets down to 15 to 20 degrees and don't use any type of frost protection.  In the summer when you have all the sun and the roots are establishing there should be absolutely no problem at all.

Answer 2

No. Only if there is a danger of frost.
