Potato onions grow like garlic bulbs; there are multiple onions that grow like cloves to one plant clump. 

Harvesting: When the onion tops fall over, remove the mulch and stop watering for two weeks. Once about half the tops fall over, the onions are ready to harvest. They can be harvested during mid summer throughout winter. You can harvest the whole cluster or take only a few for immediate use. Be sure to harvest on a dry day. 

Curing: To cure the onions, store the bulbs in a shaded, dry warm space with good air circulation. Spread them out in a single layer and allow them to cure for 1 to 2 months. Remove any spoiled bulbs throughout the curing process. After curing, cut the tops off, leaving about 1 inch above the bulb and separate the onion clusters.  

CARE INSTRUCTIONS

Perennial onions prefer well-draining soil and can be replanted from the bulb year after year. Spring Planting: Plant your potato onions in the spring if your winters are very harsh. Plant bulbs deep enough to have ½–1” of soil covering the bulbs. In colder winter areas, plant bulbs deeper to have 2–5” of soil covering the bulbs. Fall Planting: Plant your potato onions from October to December or 3 to 4 weeks before your first frost if your winters are mild to moderate. Plant bulbs deep enough to have ½–1” of soil covering the bulb. Space larger bulbs 6 to 8 inches apart and smaller bulbs 4 to 6 inches apart. The rows should be 12 inches apart from each other. Water and cover with about 2-4 inches of mulch. Very small bulbs may not multiply in the first year, but will in the second season.
