Delete the board
Discard boards that are no longer needed
If the active board is no longer needed, consider deleting it to save space and reduce clutter.
You can delete any boards that you've created. You can also delete boards that are shared with you, providing that you're included in its Editors list. Admins can remove any board they want!
To delete the board, open the Board Menu in the toolbar (top-right), choose Delete board and answer Yes to the confirmation.
Caution
Deletions can't be undone, so please think carefully before doing so!
