Okay, I have wanted a morning glory for a while. My parents had them growing up. I saw a gorgeous one today so I decided to buy it (yes it was impulse). Now I am not sure what to do with it or how to take care of it. It is in a plastic pot with a two and a half foot support. Here is what I want to know:
Do I leave it in the pot?
Do I plant it in the garden (I get mostly full sun everywhere except a couple of places that get morning to noon sun)?
What pests/diseases do I need to look out for?
Will it survive over winter? If not, what should I do?

I am a total idiot when it comes to morning glories and other vines so I need some expert help!
Thanks
