Preparing onions for storage

Debra Peters
by Debra Peters
My onions (Walla Walla Sweets) are close to being ready for harvest - the tops have fallen, anyway. Since this is my first time growing onions, I'm not sure how to proceed. Do I continue watering? When do I pull them from the ground and begin the drying process? I did read I need to dry them in the sun for a week to let them develop the papery outside.
Any suggestions will be greatly appreciated. (BTW, I live in AZ, so not problem with a long, dry spell for drying.)
