Getting Started with Onion Propagation
Growing onions from scraps is a fun and rewarding way to have fresh produce at home. You’ll need a few basic items to start this easy project. The main thing is to use the onion bottom, which has the roots needed for new growth.
Materials Needed
- An onion (any variety will work, but green onions tend to regrow more quickly)
- A sharp, clean knife
- A cutting board
- A starter pot or container with well-draining potting soil (optional)
Start by cutting off the onion bottom, leaving 1.5-2 inches of the “meat” and roots. This part will grow into your new onion plant. Then, let the onion bottom dry and form a callous in a shaded, well-ventilated spot for a few hours to a couple of days.
With your materials ready, you’re ready to grow onions from onions! Next, we’ll look at how to prepare the onion cutting for planting.
Preparing the Onion Bottom
First, get your onion bottom ready for planting. Use a sharp knife to slice off the top, leaving 1.5-2 inches of roots. This is key for how to prepare onion bottom for planting.
Then, lay the onion bottom flat on a dry spot, with the cut side up. Let it dry for 12-24 hours until it’s calloused and dry. This drying, or onion cutting callousing process, stops rot and helps new roots grow.
Slicing and Drying
Here’s how to slice and dry onions for propagation:
- Use a sharp, clean knife to slice off the onion bottom, leaving 1.5-2 inches of the root system attached.
- Arrange the onion slices on a flat, dry surface, such as a baking sheet or paper towel, with the cut side facing up.
- Allow the onion cuttings to dry for 12-24 hours, or until they are calloused and dry to the touch.
- During this drying process, the onion cutting will begin to form a protective layer, which is essential for successful regrowth.
By following these simple steps, you’ll have your onion bottoms prepped and ready for the next stage of propagation.
Potting the Onion Cutting
Now it’s time to pot your onion cutting! This step is key to growing onions from onions. Make sure your onion bottom is dry after slicing. Then, pick the best spot to plant it.
You can plant your onion cutting in the ground or in a pot with good soil. For a pot, fill it with soil, leaving room for the onion. Put the onion bottom in a hole, cover it with more soil, and water it well.
When planting onion bottoms in pots, choose a container with good drainage. This stops the roots from getting too wet. Growing onions in containers is great if you don’t have much garden space.
You can also plant your onion cutting directly in the ground. Just pick a spot with good drainage and bury the onion. It’s simple! Your onion cutting is now on its way to becoming a full onion plant.
Success comes from giving your onions the right conditions. Watch over your potted onion cuttings or in-ground onion bottoms. Adjust as needed to help them grow well.
Transplanting and Regrowing
When your onion cutting grows a few leaves, it’s time to move it to a garden bed or a bigger pot. Carefully separate any new plants that have grown from the onion bottom, making sure each has roots. Cut the leaves back to about one-third of their size before transplanting. This helps the plant grow stronger and form a bulb.
You can keep doing this to get more onions. Vanessa Greaves, for example, hasn’t bought green onions in two years, only for demos. This method makes it easy to have fresh onions at home.
- Transplant onion cuttings with attached roots to a prepared garden bed or larger container
- Cut leaves down to one-third of their original size to reduce stress on the plant
- Repeat the process as needed, harvesting onions when they form flowers
- Regrow onions from scraps to enjoy a never-ending supply of fresh produce
Moving onion plants to the garden is easy and lets you keep onions growing from kitchen scraps. With a bit of care, you can pick your own onions whenever you want.
“By regrowing green onions from kitchen scraps, individuals can obtain an almost endless supply of fresh green onions.”
Keep the roots of your onions in water and change the water weekly. Once they’re about four to five inches tall, move them into the ground or a pot with good soil. Not moving them can weaken the onions and stop them from producing.
To harvest, cut the leaves right down to the ground. The onions will keep growing from the cut ends, giving you a steady supply. In some places, these onions might even come back in the spring.

Caring for Your Onion Cutting
Taking good care of your onion cutting is key to its growth and success. With the right care, you can enjoy a great harvest of onions from your garden. Here are the main steps to follow for your onion cutting.
Watering Your Onion Plants
Onions need steady moisture to grow well. Water your onion cutting about 1 inch per week. Keep the soil moist but avoid overwatering. If you don’t water evenly, you might get bulbs that split or growth that stops.
Fertilizing for Healthy Onions
Feed your onion cutting with a nitrogen-rich fertilizer every 2 weeks before the bulb forms. This helps with strong foliage and bulb growth. Always use the fertilizer as the package says.
Maintaining Weed-Free Soil
Weeds can take nutrients and water from your onions. Remove any weeds that come up to help your onions grow better.
Monitoring for Pests and Diseases
Watch for pests or diseases that could harm your onions. Deal with problems like thrips, onion maggots, or fungi quickly to protect your crop.
By taking these steps, you’ll help your onion cutting grow well. With the right care, you’ll soon be enjoying your own onions from home!
| Care Aspect | Recommended Approach |
|---|---|
| Watering | Provide 1 inch of water per week, keeping soil moist but not waterlogged |
| Fertilizing | Apply nitrogen-rich fertilizer every 2 weeks until bulb emergence |
| Weed Control | Regularly remove weeds to prevent competition for nutrients and water |

Harvesting Your Homegrown Onions
Harvesting your homegrown onions is a big step in gardening. It’s important to know when to pick them for the best taste and yield. Wait until the plant starts flowering and the leaves turn yellow and dry.
Use a small shovel or fork to carefully loosen the soil around the onion plant. Then, pull the onion out by its leaves, being careful not to harm the bulb. Onions from cuttings usually take 90-120 days to grow a full bulb.
After picking, let your onions dry in a warm, airy spot, away from direct sunlight, for 2-4 weeks. This drying, or curing, process makes the onion’s skin dry and protective. It also helps keep the onions fresh for longer. Once dried, store them in a cool, dark place for up to 8 months.
| Onion Harvesting Tips | Ideal Conditions |
|---|---|
| Harvest when 2/3 of the foliage has fallen over | 80% foliage die-back for optimal flavor |
| Cure onions for 2-4 weeks at 75-90°F | Store at 32-36°F to prevent sprouting |
| Leave green tops on during curing | Humidity levels between 65-75% |
By using these harvesting onions grown from scraps and curing them right, you can enjoy your onions for months. Good onion harvesting tips help keep your homegrown onions fresh and tasty.
“Curing onions is crucial for better storage. Poorly cured onions are more prone to storage rots.”

Starting Onions in Pots or Garden Beds
Growing onions can be done in pots or directly in your garden. The choice depends on how much space you have and what you prefer. Both methods need the right conditions for onions to grow well.
Planting Onions in Containers
If you’re short on space or want control over your onions, containers are a great choice. Pick a potting mix that drains well and a container with good drainage holes. Onions do best in soil with a pH of 6.0 to 7.0, so adjust your mix if needed.
Growing Onions in Garden Beds
For those with garden beds, planting onions directly in the ground is fulfilling. Make sure the soil drains well and has nutrients by adding compost or fertilizer before planting. Plant onion sets or seeds in mid to late March, so they get established before it gets hot.
Whether you grow onions in containers or garden beds, they need the same care. Keep the soil moist but not too wet. Onions love full sun, so give them plenty of sunlight. With proper care, you’ll enjoy a big harvest of onions.
| Planting Method | Timing | Soil Requirements | Spacing |
|---|---|---|---|
| Onions in Containers | Mid to late March | Well-draining potting mix, acidic pH 6.0-7.0 | 4-6 inches apart |
| Onions in Garden Beds | Mid to late March | Well-draining, nutrient-rich soil | 4-6 inches apart |
Choosing to grow onions in containers or onions in garden beds is up to you. The secret to success is giving them the right conditions and taking good care of them. With some effort, you’ll get a big harvest of onions from your own garden.
Trouble-Shooting Common Issues
Growing onions can be rewarding, but it has its challenges. If your onions look limp, discolored, or unhealthy, you might have a common issue. Let’s look at some common onion growing problems and how to fix them.
Identifying and Addressing Onion Plant Diseases
Onions can get sick with diseases like pink root, downy mildew, and botrytis rot. If you see these problems, act fast. Move the sick plant away from others and get advice from a nursery or expert. Quick action and the right treatment can stop disease from spreading and keep your onions healthy.
Dealing with Weeds and Pests
Weeds and pests can hurt your onion crop. Onion thrips, onion maggots, and wireworms are pests to watch out for. Onions don’t grow well with weeds, which can slow them down. Keep an eye on your garden for weeds and pests, and deal with them quickly to keep your onions healthy.
Addressing Nutrient Deficiencies
Onions need a lot of nutrients to grow well. Phosphorus or potassium deficiency can make onion bulbs grow thick at the neck. Make sure your onions get the right nutrients from good soil or a quality fertilizer.
Being careful and fixing problems fast can help you grow healthy onions. Every garden is different, so don’t be afraid to ask experts or seasoned gardeners for advice. This way, you can overcome common onion growing issues and have a great harvest.

By solving these common onion problems, you can grow a successful onion crop. Always be alert, seek expert advice, and adjust your gardening methods for your local climate.
Seasonal Tips for Growing Onions
Onions can grow well in spring and fall, even in cold zones like 5 and 6, with winter protection. Start onion cuttings in early spring for spring planting. For fall, plant onions 4-6 weeks before the first frost. In warmer areas, onions can grow all year. Adjust your planting and care to fit your local climate and season.
Popular onion types include scallions, shallots, yellow, white, red onions, Vidalia onions, and leeks. Short-day onions work best in zones 7 and up, while long-day onions are for zones 6 and below. Day neutral onions grow in most zones.
Short-day onions form bulbs with 10-12 hours of sunlight. Day neutral onions need 12-14 hours, and long-day onions need 14-16 hours. Think about the light needs of each onion type for the best growth.
| Onion Variety | Ideal Garden Zone | Daylight Hours for Bulb Formation |
|---|---|---|
| Short-day Onions | Zones 7 and higher | 10-12 hours |
| Long-day Onions | Zones 6 and lower | 14-16 hours |
| Day Neutral Onions | Most zones | 12-14 hours |
Onions need at least 12 hours of sunlight and rich soil with compost. Mulching helps fight weeds and keep soil moist. But, be careful not to overwater to avoid rot.
Knowing the seasonal and light needs of onions helps you grow them all year. Whether in spring, fall, or year-round, you can succeed with onions.
