Q.frost on gardenia
I have a winter frosted gardenia that has green growth/leaves on the underneath of the plant but lots of brown outer leaves as a result of winter. Should I trim the brown leaves/branches off or just leave as they are? I have just fertilized the plant.

Whether you keep them or replace them really depends on how soon you want the plants to look nice again. These articles will help you:
