I am not a morning glory expert. I have found that morning glories do not transplant very well and seem to do better direct seeded into the ground. Also, they like it very warm, and I have found that it has worked best for me to plant in June when the soil is truly warm. Sweet peas like it cold.

Because I have had difficulty getting MG and moon flowers to bloom before frost, I have grown them in containers with a very careful and gradual hardening off period.

They are probably in shock...I disagree with Hoghaven, I think they transplant just fine, been doing it for years. Make sure they have adaquate water (they probably do) and wait, lots of things shock in the first warm days.
