Answer: A potato vine will be an annual plant in your gardening region. It will cover a fence, but will die off in the winter and you'll need to start all over again the following spring. If you're looking for something more permanent, you might consider planting Virginia Creeper, or even honeysuckle.
I usually start my seeds indoors 6-8 weeks prior to the last frost of the season. This will give them plenty of time to germinate and grow into transplantable size by the time the soil and the air warm up in the spring. You can start most seeds in mid- to late-February for planting out in early May.
Best wishes with your garden!
