Blooming Sinningia for the second time

After the main blooming season in spring, the speciosa type Sinningia now have their second blooming season since I cut off the old stems that bloomed in spring. Then new sprouts grow and give the blooms within short time due to the hot weather speed up the growth, meanwhile the plants do not grow big like they were in spring. Surely the bloom quantity is fewer than they were in spring as well.
