You can also set org-agenda-dim-blocked-tasks to 'invisible, which will
remove blocked tasks entirely from the agenda. Then, you could add the
property ":ORDERED: t" to the heading and schedule them (for the diary
agenda) or mark them NEXT/TODO (for the todo list). This would cause
each event to appear on the agenda after the blocking task is marked
done.

Or, since the OP is using org-depend.el (in contrib), he could also use
:TRIGGER: chain-siblings-scheduled(NEXT).
