Product description

Pick your onion, or take all three

Over a pound of live onion sets, ready to go in the ground.

Onion sets are small dormant bulbs grown last season and held over. You're not starting from seed and waiting half a summer for something to happen. You're planting a bulb that already exists and asking it to get bigger, which is a much easier thing to ask.

That's what makes sets the most forgiving way to grow onions, and a good first crop for a new bed or a first-time gardener.

Choose your color

Tri-Color Mix. Red, yellow and white together in one pound. This is the one most people should take. You get all three of the onions you actually cook with from a single planting, and you find out which does best in your ground before you commit a whole bed to one kind.

Yellow. The workhorse. If you only grow one onion, grow this one. It's what most recipes mean when they just say onion, and it stores the best of the three.

Red. Deep red-purple skins, milder and sweeter raw. The one you want for salads, salsa, and anything going on a burger.

White. Crisp and sharp, the classic choice for Mexican cooking, and usually the first of the three to reach eating size.

What arrives

Over a pound of live dormant onion sets, in whichever color you pick.

This is a farm product, not a manufactured one, so the count and the size of the bulbs vary from bag to bag. The weight doesn't. You get over a pound every time, which is why we sell it by weight rather than by the count.

When to plant

Onion sets go in early. As soon as the ground can be worked in spring, or through the fall if your winters are mild. They take cold better than most things you'll put in the ground.

How to plant

About an inch deep, four to six inches apart, pointed end up, with the top of the bulb sitting right at the soil surface. Don't bury them.

Pick a spot with good drainage and plenty of sun, and keep the soil consistently moist while they establish. Onions have shallow roots and they lose to weeds, so keep the bed clean and they'll handle the rest themselves.

Want green onions instead? Plant them an inch or two apart and pull them young. Sets are the fastest route to scallions there is.

Common questions

What is an onion set?
A small onion bulb grown from seed last season and held dormant. Planting one is faster and far more reliable than starting onions from seed.

How deep do I plant onion sets?
About an inch, pointed end up, with the top of the bulb at the soil surface.

How far apart?
Four to six inches for full-size bulbs. An inch or two apart if you want green onions.

Can I grow them in containers?
Yes. Onions are shallow-rooted, so a pot six to eight inches deep is plenty.

How many will I get?
It varies, because bulb size varies. You get over a pound by weight every time, which is the honest way to sell them.

Which color should I pick?
If you're not sure, take the tri-color mix. You get all three and you learn which one likes your ground.
