$ git gc --prune=now
$ git remote prune origin

man git-gc(1):

git-gc - Cleanup unnecessary files and optimize the local repository

git gc [–aggressive] [–auto] [–quiet] [–prune= | –no-prune]

Runs a number of housekeeping tasks within the current >repository, such as compressing file revisions
(to reduce disk space and increase performance) and removing unreachable objects which may have been
created from prior invocations of git add.

Users are encouraged to run this task on a regular basis within each repository to maintain good disk
space utilization and good operating performance.

man git-remote(1):

git-remote - manage set of tracked repositories

git remote prune [-n | –dry-run]

Deletes all stale remote-tracking branches under <name>. These stale branches have already been
removed from the remote repository referenced by <name>, but are still locally available in
"remotes/<name>".
