Whether t-logs are truncated in DB's particpating in High Availability. SQLAlways On 2012

Hi,

How the transaction logs are cleared for DB's participating in SQL AlwaysOn.I have a DB participating in HA.Now in order to use alwaysON DB recovery model should be set to full. NOw  with this recovery model my transaction logs will grow continuously.

How t-logs can be cleared for the DB's participating in AG. Is there any recommendation?

Thanks
