Rebuild civilization and execute it completely

So, the apocalypse has happened.The zombies have come and gone,and all plant life on Earth has died somehow.All you have are some basic supplies and some seeds of a few types of essential plants. So, what should you do to make absolutely sure they grow,seeing how rebuilding human civilization absolutely depends on it?Well, you'd probably think the last thing you should do with these crucially important seeds
is something like poking holes in them,or grinding them with sandpaper,or throwing them in acid or hot water.
