Vegetable Seeds - Onion, Sets

Because they’re already on their way and have more stored energy than seeds, sets get growing faster, are more disease resistant than seed and are easier to handle. If you’re late sowing then sets can save the day and can go in as late as the end of April. For help in growing onions from sets check out our guide here: Grow Your Own Onions from Sets
