In February we will having a class on growing Potato Onions by Kelly Winterton who developed large multiplier onions here in northern Utah! These onions grow like garlic, with 2-8 onions cloning from each onion. The onions are 1-3" in size and they store well. You can plant them in the fall at the same time as your garlic, or in the spring. Kelly will be bringing seed for us to grow out, which we can then grow as clones.
If you are interested in getting seeds, please read this booklet now by Kelli to learn about them.
