Some of your storage vegetables need to be cured before storage; some don't.  If you cure vegetables that don't need to be cured, they'll rot.  And if you don't cure vegetables that do need to be cured, they'll rot too.  Time for a good list!

The cheapest and easiest method I've come up with for curing vegetables is to lay them out on some old window screens Mom found for me by the side of the road.  I put the first screen on four cinderblocks, cover the screen with drying vegetables, then put bricks on the four corners of the frame to let me put another screen on top for a second drying layer.  The trick is to get good air circulation all the way around your vegetables, so don't pile the roots on top of each other.  If you're a good scavenger, you can recreate my curing rack setup for next to nothing.
