In order to decide, you’ll need to understand the differences between the two!

Onion seeds are onions that have not started to grow. Onion seeds are considerably less expensive than sets and you will find a much larger variety. However, they need to be started very early indoors so if you’re late getting started or you prefer direct-planting outdoors, you’ll need to look into onion sets instead.

Onion sets are onion seeds that have already grown for one year. They’ve been dug up and stored over the winter so they are ready to be planted directly into the ground. Since they are already a year old, sets will yield full-sized bulbs at the end of the season without being started indoors.

As you get acquainted with gardening, you will likely develop a preference for one over the other. Some gardeners do not like the tendency for sets to bolt and claim that seeds yield larger onions. Others will tell you that simply pinching the shoots off the sets will prevent bolting and they are perfectly happy with the size of their bulbs at harvest.

As with anything in the garden, factors like soil quality, weather, and each unique gardener can have a huge impact on your results. We recommend having fun with trying new things in the garden and you can never have too many onions! They are so versatile you can be sure to always use them in the kitchen.

One thought on “Should You Buy Onion Seeds or Sets?

  1. I wonder which onion is best as a keeper for next winter. Which one grows best when its hot out. We had a problem last winter with the yellow onions we grew. We dried them for a long time but they started to rot after being stored for only a month or so. Wonder what i did wrong or was it the type i bought. I bought yello and red sets from a store in my area. Thanks for your help. Lin
