ONION SEEDS....

The advantage of growing from onion seed is that you open yourself up to a wide range of varieties. Although you can direct seed into the ground in warmer climates, onion seeds take a long time to grow and mature. To make the most of your onion growing experience, consider starting from onion seed. This will give you access to a diverse array of onion varieties to choose from.

That means for warmer climates, they need to be go in the ground in the fall or late winter. For northern climates, start seeds indoors 10 weeks prior to moving outside to transplant. In essence, this is the process of planting onion transplants or seedlings. And, it is a much better way to go when planting from seed.
