The issue with store bought
The issue with store bought Alliums (garlic, onions, and shallots) is they are not certified disease or pathogen free. If your store bought plants are carrying a disease it can spread to the existing Alliums in your yard. If you want to plant them out make sure they are separated by as much distance as possible from your other Alliums. Grow them out for a couple of years and watch for disease. If they remain healthy during that time there’s probably no issues with them. Pay particular attention to fertilizer, moisture, and drainage.
