Laura, Morning Glories can be gorgeous BUT bossy. To start the seeds I usually
nick them with a nail file or something similar. I put them in a warm wet paper towel over night. This helps them start sprouting. Then plant where I want them. They like some morning sun. Give them something STURDY to grow on. Yes they can be grown in pots although I have never done this. With my zone 6-7 they make seeds come the fall. Either leave the seeds or gather for next year. I've had plenty of last seasons seeds come up on their own. Don't bother with fertilizers. That'll give you more leaves than blooms. I've had some vines grow very tall and take over my pergola. One of my favorite vines but use some caution when and where planting because of their aggressiveness.
