How to grow Rosemary indoors over the winter?

I live in northern Colorado on the plains and the rosemary that thrives in the summer never makes it through the winter in a pot. It slowly dries up and dies even though I water it and keep it in a sunny place. What should I do to keep it alive?

What happens with rosemary if I don't let it hibernate over the winter?

I have a 1 year old rosemary. I read in several (non scientific) articles that I have to put it to 10°C in winter, so it can hibernate (I guess). (Outside it would freeze I think, we sometimes get -15°C during the winter.) Now my problem is that I…

Salvia rosmarinus - frost hardiness

I found it can survive -6 °C. But that's not clear, is -6 °C for 2 weeks still fine? Is -2 °C for a week still fine? In both cases, it means 24/7 frost, it's not the same as temporary temperature fall and day temperature above 0. So far, after 3 day…
