Thom Multiplying Onions are an heirloom variety that has been grown for many generations. This particular strain derives from Thomas County, Ga. A true multiplying onion that is extremely easy to grow; they will grow great in raised beds or in-ground gardens. Once these onions are established, you will never have to buy them again. Thom Multiplying Onions are delicious when eaten raw, sauteed, or grilled. Allium cepa

We suggest harvesting and splitting bulbs twice a year (Fall and Spring) if you live in Zone 8 and higher. Zones 7 and lower should harvest in the fall and store bulbs in a cool, dry, and dark area until you're ready to split and plant the following Spring. Thom Multiplying Onions are not a potato onion or a walking onion.

Onions are heavy feeders and will require significant nutrient inputs throughout their lifespan. We recommend feeding them with our 20-20-20 and Ammonium Sulfate fertilizers. Fertilize with 20-20-20 shortly after transplanting. The phosphorous and potassium in the 20-20-20 fertilizer will help to promote solid root development, while the nitrogen will promote vegetative growth. Once transplants are established, we recommend side-dressing or injecting with our Ammonium Sulfate fertilizer. Side dress or inject 1 cup per 20 feet of linear row every 3-4 weeks after transplanting.
