My two 6-yr old blue balloon flower plants are full of buds but have not bloomed since spring this year. Is there anything I can do to make them bloom? Also, when is a good time to transplant them? They are crowded by lantana. Any suggestions for transplanting?

The soil could be lacking phosphorus, which is needed for blooming. You can try a phosphorus-rich fertilizer or adding bone meal to the soil. As for moving them, this would be difficult. They typically do not like to be disturbed. However, you can always give it a try once summer begins winding down. Just in case though, I would take some cuttings to root for next season as well.
