Have you cut them back? Often that will refresh them and they will bloom on the new growth.

Maybe I'll give that a try. I was thinking about doing just that, but thought I'd post first for possible answers.

I've seen Calibrachoa both in the Midwest and on the PNW this past two weeks. They were gorgeous in the PNW, but looked pathetic in the Midwest. I think the weather and moisture have a lot to do with this plant's performance.

Some of my calibrachoa ('Pink Kiss' & 'Melon') have done great from the start. The others, 'Rose', 'Lavender' and 'Terra Cotta' have just started doing really well. I've had these kinds for a few years and it seems like some just need a little longer to fill out than others. I don't deadhead them much at all, but I do trim them every so often. I don't trim all the stems at once. I do it here and there. They'll branch out really nice. Also, what are the numbers on your fertilizer? I also use a fertilizer with a higher middle number for more blooms. Nitrogen helps to make a lot of good leaves, but doesn't help for the flowering. So use a fertilizer with the middle number the highest. I use a 10-15-10 every 2 weeks. I've had bacopa a few times and it does seem to bloom in flushes. But trim back some stems and see how that works.
Good luck with yours and I hope they all pick up!

The fert is 15-30-15.

The fertilizer sounds good, I'm sure the trimming will help them fill out and bloom more. Just give them a week or 2 to show some improvement.
Enjoy!

I'll try a trimming then. Thanks to everyone!
