Aloe DO NOT like cold.....I would suggest moving it to a pot and bring indoors. Give as much direct sunlight as possible and very litle water. I don't know how cold it has been there, but cold and wet equals disaster to an aloe...trust me- I found this out quite by accident as I almost killed mine last year!
Margaret e pell or Comfrey( I know there is someone else I am forgetting, but.....) know more than I do, but from my understanding:
Fast draining soil + lots of sun + small amounts of water = a happy aloe!
Best of luck to you!!!
