<< Back to Gardening TipsOnions
You’ll want your onion plants outside in the garden about 3 weeks before your last frost date. They can handle a little frost. So if you are just direct seeding, you’ll want to get your seeds planted outside at that time. Plant them the same depth (1/4″) as indoors, and keep them 2 to 3 inches apart. Green onions can be planted about an inch apart or just scatter the seeds, and thin them later.
Transplants should go out at the same time. Dig up the soil to loosen it and apply Blessings Blends OMRI-Listed Premium Compost (.5 – .5 – .4) for best results. Onions bulbs don’t grow down very deeply, so you don’t have to remove stones for more than a few inches.
For onion sets, they’ll also go into the soil at the same time as any transplants. Onion sets don’t really need to be buried, but rather just pushed slightly into the ground on the surface. Set them upright with the point upwards.
