We’ve received our first delivery of onion sets and onion plants. We have both white and yellow onion sets, and Walla Walla, Candy, Red Candy Apple and Yellow Sweet Spanish onion plants. If you grow in raised beds the soil might be just right for planting. If you grow in the ground, it may still be a little cold and wet– check before you plant.
If you buy them and can’t plant yet, keep the plants in a cool, dry place– not the refrigerator– until you are ready to plant.
Plant them one inch deep and four inches apart if you want to let them grow until they mature and form large onions. Or do as we do, and plant the 2 inches apart and pull every other one as they get some size to them for use as green or spring onions and leave the others to mature. Fertilize with a fertilizer that has a higher middle number, such as 5-10-5. If you are confused about what the fertilizer numbers mean check out our blog post here.
