To get the plant to grow this high, I feed it both liquid and time-release pellet fertilizer. I also plant them in a combination of organic manure and native soil. If you do not have space like that you can plant them in containers as well. I have a friend who lets them run along a railing on her patio.
Morning Glories do best in at least 1/2 day of sunshine. Keep them evenly watered during the hot weather. They will droop if they get dry. I use neem oil on the leaves until they get established. This helps protect the young plants from being eaten by bugs.
Heavenly Blue has wonderful sky-blue flowers that burst open at sunrise and stay open till about 1pm. I notice in the cooler fall weather they can stay open all day.
Once you get a light frost, the plants will die, but what a great summer show!
