Trim your petchoas occasionally to encourage more branching which leads to increased blooms. To keep your petchoas looking beautiful all season, the recommendation is to fertilze every other week. 

Supercal Premium Petchoas are a hybrid of calibrachoa and petunia. The flower size is larger than a calibrachoa, but smaller than a petunia. They offer a well branched and tidy growth habit covered in blooms from spring to fall. They can handle cooler temps, but not a hard freeze.
