My Heavenly Blue Morning Glory was pruned last week just as it began to bloom. Today is September 1. What can I do to save the blooming season?

    Welcome to the site, Jane! It would be helpful to know where you are in the world, and how far back the plants were cut. Pictures would be awesome, too.

Depending on where you are located, your first frost will be anytime from now till mid-November. In any case, This is an annual morning glory, so it will do it's best to flower and go to seed before frost kills it. These plants sense seasonal changes by day-length, temperature changes, and a couple other things. These things tell the plant Fall is coming, and they don't have much time left to live, so they will grow quickly, and put out as many flowers as possible.

Things you can do to extend the season are:

  • Cover the plant overnight once frost is predicted. If you don't have row cloth, bed sheets will work fine.
  • Frost Patrol® Plant Protector basically causes a change within the plant, which lowers the temperature at which the plants cells become damaged by 1 or 2 degrees. Spray it 48 hours before you expect frost.

And it will depend partly also on how far back it was pruned. If it was cut back less than 1/3, that's the best case, and you should get flowers again in a couple weeks. If it was cut back by 1/2 or more, it is going to try to regrow that before flowering much, so if that's the case, don't expect too much from them. But as I said before, flowering is a high priority now for the plant, so don't lose hope.
