Onions are great to grow because they bring a big harvest from a small space. They can also last for many months once harvested. Planting onions the right way is key to a good harvest. This guide will show you how to successfully plant onions, from choosing whether to use onion sets or seeds to soil prep, planting, caring for your crop, and finally harvesting and storing. With this advice, you can expect a lot of onions from your garden.

• Onions can be grown from sets or seeds, with sets offering a quicker and more reliable option.
• Well-draining, nutrient-rich soil is essential for growing healthy onion plants.
• Proper planting depth, spacing, and fertilization are crucial for optimal bulb development.
• Consistent moisture, weed control, and pest/disease management are important for ongoing onion care.
• Selecting the right onion variety for your growing region can make a big difference in yield and flavor.

When you’re ready to grow onions, you can pick onion sets or onion seeds. Every choice has its benefits. Knowing these perks helps you choose wisely for your garden.

Folks who enjoy gardening often prefer onion sets. These are small onion bulbs already started. They grow fast, are more likely to succeed, and can handle some cold. In just 14 weeks, they become full-sized onions.

When choosing onion sets, go for those that are about 3/4 inch wide. Bigger sets might not do as well. They could end up with a hard center or go to seed too soon.

Starting from onions from seed is another good choice. Yet, the soil must be at least 50°F for the seeds to sprout. That means you need to start them inside before putting them in your garden.

Whatever method you pick, make sure you choose the right onion varieties for your area. There are types suited for different climates, like long-day or short-day onions.

Getting your soil ready for onion growing is the first step to success. Onions love soil that’s well-draining and full of organic goodness. Mixing in some aged manure or compost makes the soil great for planting onions. This step also boosts the soil’s texture and fertility.

Preparing your onion bed means digging deep — about 6-8 inches. This depth allows onions to grow strong roots. Consider raising the beds or making rows. This setup helps with drainage, which is key for onions’ health. The right soil setup is essential for onions to thrive.

Onions need lots of sun to grow big and healthy. So, pick a spot that gets sunlight all day. Don’t plant near plants that could block the sun. Early on, in the fall or spring, prep your onion bed well. Remove rocks and debris to set up the best growing space.

Onions are best to plant in early spring. This is usually in late March or April. At this time, the chance of freezing is low.

For onions planted in spring, bury them 1-2 inches deep. Space them 4-6 inches apart. Rows should be 12-18 inches apart. Onions planted in fall need several weeks in warm weather to grow, before the cold stops their growth in winter.

It’s important not to plant onions too deep. This affects how well their bulbs grow.

Bury the sets between 1-2 inches deep. Space them 4-6 inches apart. Leave 12-18 inches between rows. This allows for good growth and lets air circulate around the plants.

Adding nitrogen to the soil when planting helps onions grow big bulbs.

Some gardeners also put an inch of compost in the soil or dig trenches. This enriches the soil. It gives the onions the extra boost they need to thrive.

To grow great onion plants, you need to care for them well. This involves regular watering, careful weeding, and keeping pests away. By doing this, you can make sure you get lots of onions when it’s harvest time.

Onions like a steady amount of water, roughly 1 inch a week, which includes any rain. Their roots are shallow, and they don’t absorb water quickly. So, keeping the moisture consistent helps them grow well. This is even more important when they start forming bulbs, as it avoids them growing poorly or splitting.

Keeping the area around onion plants weed-free is crucial. Weeds can take water and nutrients away from the onions. Mulching helps a lot. Spread 2-3 inches of straw between the rows. This keeps the soil moist, stops weeds, and lets air flow around the onions. Just remember to keep young bulbs lightly mulched to help them grow strong.

Onions deal with many pests, like thrips, onion maggots, and aphids. One way to keep thrips away is to plant onions near tomatoes or carrots. To stop onion maggots, cover the plants with netting once they’re coming up. And always watch out for diseases like purple blotch or downy mildew. If you see any signs, deal with them fast. Stopping pests and diseases early is the best way to keep your onion crop healthy.

Onions need different amounts of light to grow well. So, it’s important to pick the right kind for where you live. This ensures they grow big and healthy.

‘Yellow Sweet Spanish’ and ‘Red Wethersfield’ like a lot of sun. They do the best in the north where there’s over 14 hours of daylight. For gardeners up north, these onions are a great choice for a good harvest.

‘White Bermuda’ and ‘Red Burgundy’ do well in the south. They prefer having less than 12 hours of daylight. If you’re in a warm, southern spot, these onions will work perfectly for you.

For those in between, ‘Candy’ and ‘Super Star’ onions are ideal. They aren’t picky about how much light they get. This makes them a smart pick for spots with changing daylight hours.

Knowing the right time to harvest your onions is key. It ensures a successful crop and that your hard work pays off. Follow the best practices to make your onion harvesting effort rewarding and long-lasting.

Onions are ready for onion harvesting when their tops turn yellow and flop over. This happens in mid-summer for onions planted in the spring. After this, loose the soil around the bulbs to help them dry.

Harvest them on a dry day and handle them gently. This prevents bruises, which can cause rot later. Once pulled, cut the roots and the tops down to 1-2 inches. If you want to braid them, leave the tops on.

Onion curing is vital for storing onions long-term. Place them in a dry spot for a week or two. This allows their necks and skins to dry out. Once this is done, they can be stored in good condition.

After curing, you can hang the onions in mesh bags, store them in boxes, or braid them. Do this in a cool, dry place with good airflow. This way, your onion harvesting methods match the right onion harvesting season. This leads to top-quality onions that last a long time.
