Cardinal Climber Vines Are Not Blooming

Q: My three sunny cardinal climber vines are not blooming. They’re pretty big and green but no blooms. 

A: Cardinal climber, and its parents, cypress vine and red morning glory, are vigorous annual vines. Given a good site in which to grow, they shoot up rapidly. I think they sometimes initially put more energy into growing than into putting on flowers. If your vines are healthy in mid-July, they should be getting ready to bloom soon.
