When To Plant Onions

There’s nothing like the taste of freshly-picked onions. But if you want to enjoy the taste, you have to plant onions at just the right time. This article will tell you everything you need to know about when to plant onions in your garden so that you can get a great harvest of these tasty vegetables!

When To Plant Onions

Planting onions is a little different from planting other vegetables. Onions are a cool season crop, so they should be planted in the fall or early spring. In most areas, it’s best to plant them in the fall so they have time to mature before the heat of summer sets in.

You can also plant onions in the spring if you live in an area where there is no danger of frost.

If you’re growing onions as a vegetable crop, you’ll need to wait until the soil has warmed up enough for them to germinate and grow properly.

Where Is The Best Place To Plant Onions?

You can plant onions just about anywhere, as long as they get full sun. In fact, onions love the full sun so much that if you have a shady spot in your garden, you might want to consider planting some there instead of trying to grow them in the shade.

Onions are a great crop for beginning gardeners because they’re so easy to grow! They’ll do well in any garden space from small containers on a balcony or patio to large raised beds and fields. There’s no need for too much soil preparation before planting—just make sure it’s well drained (ideally sandy loam) and add some compost or fertilizer according as needed later on during the season.

What Is The Best Month To Plant Onions?

The best times for planting onions are in late August or early September for an early harvest, or mid-October to early November for an October harvest. The first frost date determines when you should plant your onion seeds or sets (small bulbs). For example, if your first frost date is around November 15th, then you should plant your seeds or sets around August 15th or so – although this will vary depending on how cold your winters are.

If you live in an area where there are extreme winters and you don’t want to risk your crop being wiped out by frost (especially if you’re growing from seed), start growing your own onion bulbs indoors under lights at least eight weeks before last frost date so they can grow strong roots before being transplanted outside once all danger of frost has passed.

How Long Do Onions Take To Grow?

Onions take about 90 days to grow from seed to harvest. This means that if you plant your onions in the spring, they’ll be ready for harvest by the end of summer.

Onions can also be grown in the fall and winter if you have a greenhouse or other indoor space where they can thrive without being exposed to extreme cold temperatures outdoors.


As you can see, there are many things to consider when deciding when to plant your onions. To have a good harvest during the summer, it’s best to plant onions after the last frost in spring or in late August for fall harvesting.
