annual vines to shade south-facing wall and windows
I picked up some Heavenly Blue morning glory seeds for my garden. But I'm also thinking about sowing some in a container to grow up strings in front of a south facing wall and two windows. Have you grown morning glories in containers before? Last time I tried it, the plants were really puny. I was thinking maybe they need a lot of soil to grow deep roots in order for the vines to reach a good size. What do you think? My containers were refrigerator drawers, maybe12 X 16 X 6 inches, 6 being the depth. I could find bigger containers now.
