Onions are a cool weather crop, and can be planted as soon as the ground can be worked in the spring. They are usually planted from seed, and will take about two months to mature. Onions can also be planted in the fall, and will overwinter in most climates.
Planting onion seeds is a simple process that can be done indoors or outdoors. To plant indoors, start by Fill a seed starting tray with a quality seed starting mix and moisten the mix thoroughly. Sow the onion seeds on the surface of the moistened mix, spacing them about 1/4 inch apart. Gently press the seeds into the mix so they make good contact with the growing medium. Water the tray again tosett the seeds and place the tray in a warm location. The onion seeds will germinate in 7-14 days. Once they have germinated, provide them with 14-18 hours of light per day, either from a grow light or a sunny windowsill.

Can you plant onion seeds straight into the ground?
Onion seeds can be planted directly in the garden bed. However, when growing onion seed, some people prefer to start them indoors. This can be done in late autumn. The best time for planting onion seeds outdoors is in spring, as soon as the soil can be worked in your area.
Onions are a versatile vegetable that can be planted in a variety of ways. One method is to plant onion sets without soaking them first. However, soaking the sets in water or compost tea before planting will encourage quicker germination. Additionally, soaking the sets in compost tea will give them added nutrition and protection from disease.
What is the best way to plant onion seedlings
Onions are a cool weather crop, so they can be one of the first vegetables planted in the spring. If you live in a warm climate, you can also plant onions in the fall. Onion starts or sets are small onions that have already been started and can be planted directly in the garden.
To plant onions starts or sets in your garden, choose a full sun location if possible. Onions will also grow in partial sun, but they will not produce as many onions. Plant onions in loose, well drained soil. Make a hole in the soil with your finger that is about the size of the onion start or set.
Place the onion start or set in the hole root end facing down. Cover the onion with soil and firm it down gently. Water the onion well. Onions should be planted 6 inches apart in rows that are 1 foot apart.
They are usually planted in spring, from mid-March to mid-April. Some cultivars are suitable for planting in October to mid March – these are less sensitive to cold, which would otherwise cause bolting.
How long do onions take to grow from seed?
Onions are one of the vegetables that take the longest to grow. They require 90-100 days to mature from seed, which is around four months. From sets, onions are ready to harvest after around 80 days, or just under three months.
Onions require full sun in order to grow properly. Be sure to select a location for your onions that won’t be shaded by other plants. The soil for onions needs to be well-drained, loose, and nitrogen-rich. You should till or turn your garden soil as soon as it is workable in the spring.

Is it better to grow onion from seed or bulb?
Growing onions from seed is unquestionably the most economical way to grow them. It’s also typically the only way to grow unique or unusual varieties. Seeds can be sown directly in the garden as soon as the soil can be worked in April or early May. If you start your onions from transplants, you’ll have to pay for the plants themselves and you’ll be limited to the varieties that are available as transplants. But if you grow your onions from seed, you can choose from literally hundreds of different varieties, many of which are not available as transplants. And, of course, it’s much cheaper to buy a packet of seeds than it is to buy transplants.
If the ground near your plants is dry up to your first knuckle, it’s time to water. In a typical 12 week growing season, we recommend irrigating with one inch of water once or twice a week depending on the amount of rainfall received.

How long do I soak onion seeds before planting
Soaking your onion seeds before planting them can have a number of benefits. For one, it can make them easier to handle when you’re ready to plant them. Soaking them in water, compost tea, or Superthrive can also help them germinate faster and improve overall plant health.
Onion seeds often do not have a 100% germination rate, so for best results, plant 4-8 seeds per hole. Sow the seeds no deeper than ¼”.
What are the two methods of planting onion?
Onions can be planted in three ways: by sets, transplants, or direct seeding. Sets are grown from seeds and produce small bulbs, and then become dormant. Transplants are young onion plants that are grown from sets or direct seeding, and are then transplanted into the ground. Direct seeding is when onion seeds are planted directly into the ground.
Onions are one of the easiest vegetables to grow. They can be grown in a sunny spot with fertile, well-drained soil. The pH of the soil should be between 60 and 68. You can improve your native soil by mixing in several inches of aged compost or other rich organic matter. Onions are not great at taking up water, so it is important to keep the soil moist so their shallow roots can drink up.
How deep should onion seeds be planted
When planting onion sets, it is important to sow the seeds ½ inch deep in the ground. Onion sets are dormant bulbs that can be planted directly into the ground. Once the plants begin to grow, thin them out to 3 to 4 inches apart.
To grow onions from seed, the pre-sprouting method can be used. Chit seeds by sprinkling them over moist paper towels and wrapping them in plastic to retain moisture. I usually sprout our seeds in a germination chamber. This chamber keeps the seeds at a consistent temperature and humidity, which is ideal for sprouting. Once the seeds have germinated, transplant them into pots or your garden. Be sure to give them plenty of space to grow!
Can I direct seed onion seeds?
Onions are one of the easiest vegetables to grow from seed, and growing them from seed is also the cheapest way to get onion plants. You can sow onion seeds directly into the garden soil, but before you do, refer to the garden bed preparation section below. Draw a line down the middle of the bed about 1/8 – 1/4 inch deep and sow the onion seeds with about 3-inch spacing to avoid crowding.
One onion grows from an onion set or seed.
Are onions easy to grow from seed
Growing onions from seed is easy! You can choose the exact varieties you want to grow, and you’ll have a quicker start than if you started from seedlings or sets. Plus, onion seedlings are like small green onions, so they’re perfect for snacking on!
Sets are small onions that are grown from bulbs. They are a good option for fall planting because they are already a few steps ahead in the growth process. One bulb will produce one onion, so you can plant them 2” apart if you want to harvest them as scallions or ‘green onions’. If you let them mature into full-sized cooking onions, plant them 4”-6” apart.
Why are my onion seeds not growing
Onion seeds will not germinate if the temperature is too cold. The optimum soil temperature for onion seed germination is 75°F. If the soil temperature is cooler than this, the onion seeds will not germinate.
In general, two to three seeds should be planted per hole. Seeds do not have 100% germination rates, so not every seed planted will sprout. Overseeding holes, cells, or pots will help ensure that the number of plants you desire will grow (or more!).
Final Words
In order to plant onion seeds, you will need to first purchase a packet of onion seeds from a gardening store or seed catalog. Once you have your seeds, you will need to decide whether you want to start them indoors or plant them directly outdoors. If you choose to start your seeds indoors, you will need to plant them in pots filled with a high-quality potting mix. Be sure to plant the seeds about 1/4 inch deep and keep the soil moist but not soggy. Onion seeds typically germinate in 10-14 days.
If you choose to plant your onion seeds directly outdoors, you will need to wait until the soil is warm and all danger of frost has passed. Choose a spot in your garden that gets full sun and has well-draining soil. Sow the seeds about 1/4 inch deep and Thin the seedlings to 4-6 inches apart once they have germinated.
If you want to plant onion seeds, you’ll need to start them indoors about 6-8 weeks before the last expected frost in your area. sow the seeds about ¼ inch deep in seed-starting mix and keep the soil moist but not wet. Once the seedlings emerge, thin them so that only the strongest seedling remain. When the seedlings are 4-6 inches tall, they can be transplanted outside.
