Herbs!

Oh my gosh, I cannot get enough of herbs. Recently, Stu and I planted some herb seeds in pots (as we have a tiny apartment and no garden) and we're really excited to start seeing some shoots! We bought sweet basil, tarragon and rosemary plants, as well as curly parsley and chives. We decided to get them so that we could have a choice of the freshest herbs freshly picked from our own balcony when we're cooking. There have been a few problems copping up though, and we're trying to work through them. For example, our plants were attracting little fruit flies so we decided to put them outside, where they started wilting from the cold. Any advice on indoor herb gardening/ outdoor herb upkeep?
