I'd say I'd you're zone 6 or higher leave it outside! I have a lot in my garage as we're moving my garden and am in 4b now, they won't survive in pots outside (I've tried!). I water them every couple of weeks now and it gets less frequently as it gets colder, opposite as it warms in the spring. It works but it's not optimal. Works in an unheated garage or storage room, I wouldn't try them inside the house at all.
