'They also arranged to have their stores of onions reconditioned because they had begun to spoil.' 
  
 How does one recondition an onion?

Peel outer layers off to remove the rotting layers and make sure the surface is a single, undamaged layer.  The onion will be much more resistant to further rotting with the rotting layers removed and an undamaged surface layer. 
  
 If an onion is starting to rot in your pantry, you can extend its shelf life by a few weeks this way.
