5 Tips How to Grow a Ton of Onions in One Container or Garden Bed
How to Grow an Onion from an Onion
Onions are as simple to grow as they are delicious to eat in a variety of dishes. And, as long as you have another onion on hand, you don't need to grow them from a seed. By chopping the bottom of an onion off and planting it in soil, you can grow your own onions from cuttings. With patience, time, and plenty of water, you can grow an onion from an onion in 90-120 days.
Preparing an Onion Cutting
Chop the onion about 1 in (2.5 cm) from the bottom.Place your onion on a cutting board and, using a sharp knife, cut off the bottom and remove the outer peel. Your onion piece should be about 1 in (2.5 cm) long to grow a healthy onion.
- If you're growing the onions outside, start your cuttings in early spring. For onions grown indoors, any time of the year is fine.
- You can use most onion varieties, including grocery store-bought onions, for growing more onions. This technique works best if you work with a fresh onion that has not yet gone bad.
Leave the onion bottom out to dry for 12-24 hours.After chopping the onion, discard the rest of the onion and place the bottom on a flat, dry surface with the cut side up. Let the onion bottom dry out for up to a day until it is calloused and dry to the touch.
- If not discarding, you can use the rest of the onion for cooking or for compost if you prefer.
Poke toothpicks into each side of the onion.Divide your onion bottom into 4 sides, and poke a toothpick halfway into each side. The toothpicks should be equally spaced apart so they resemble an "X" in spacing.
- This will allow you to suspend your onion over water while it roots.
Hang the onion over a small bowl of water.Fill a bowl with water to the brim and place it on a flat surface. Position the onion so the bottom just touches the top of the water, and leave it to grow for 3-4 days. Plant the cutting when it begins growing small, white roots from the bottom.
- The bowl's diameter should be less wide than the length of the toothpicks.
- To help the cutting grow faster, suspend the onion near a sunny window or place it outdoors.
Planting Your Onion Cutting
Fill a pot with well-draining soil.Purchase a well-draining soil mix and a large pot with holes in the bottom from a plant nursery. Fill the pot with the soil to about halfway full—you will fill it the rest of the way when you plant the onion cutting.
- You can also plant your onion bottom outside if your garden has well-draining soil.
- You can test to see if soil is well-draining by digging a 12 in (30 cm) hole in the soil and filling it with water. If the water drains in 5-15 minutes, the soil is well-draining.
Place the onion cutting in the soil and fill the pot with soil.When the onion cutting grows white roots from the bottom, position it in the center of the soil. Fill the rest of the pot with soil over the onion until 1–2 in (2.5–5.1 cm) from the top of the pot.
- Depending on your preference, you can keep the onion cutting indoors or outdoors in sunny weather.
Water the onion cutting immediately after planting it.Watering the onion cutting helps it adapt to its new environment and grow roots faster. Give your onion enough water that the soil is damp to the touch, but not soaking wet.
Spray nitrogen fertilizer into the soil after watering it.Onions thrive in soil with a high nitrogen content. Spray nitrogen fertilizer directly into the soil and mix it with your hands to give your onion the nutrients it needs to grow.
- You can buy nitrogen fertilizer from most garden stores or nurseries.
- Check the label to determine how much fertilizer to spray into the soil.
Caring for Your Onion
Give your onion about 1 in (2.5 cm) of water per week.Onions need plenty of water to stay healthy and grow more onions. Check the soil every day—if it feels dry to the touch, water your onion until it feels moist.
Weed your garden regularly, if outside.Onions have a hard time competing with invasive plants, and weeds can steal their water and nutrients. Check your garden often for weeds and, if you notice any, pull them right away.
- Avoid spraying weed killers around the onion, as most herbicides can kill both weeds and garden plants.
- Check for small insects or other pests on your onion as well and, if you see any, spray the onion with a non-toxic, plant-friendly insect repellent.
Fertilize your onion every 2 weeks.Fertilizing your onion plant regularly helps it grow large, healthy bulbs. Spray the onion plant at least twice a month with a nitrogen-rich fertilizer until the onion plant's bulb starts to poke from the soil.
- When the bulb starts poking out of the soil, stop fertilizing the onion until you harvest it.
your onion when it forms flowers.When your onion starts to grow flowers, it's ready to harvest. Loosen the soil around the onion with your shovel and pull the onion by the base of its green foliage to pull it out of the ground.
- On average, it takes onions grown from cuttings about 90-120 days to grow a new bulb.
If you want to grow an onion from an onion, start by cutting off the bottom inch of the onion and letting it dry out for 12 to 24 hours. After it’s dried, poke 4 toothpicks into the sides of the onion, fill a bowl with water, then suspend the onion over the bowl so that the bottom of the onion is touching the top of the water. After 3 to 4 days, when you see roots growing out of the bottom, transfer the onion into a pot filled with soil, then bury it.
- If you initially grow your onion in a pot, you can always transfer it to your garden outdoors later on.
- As long as you care for your plant, your onion cutting should produce more onions as long as an onion grown from a seed does.
- Make sure that you care for it and pull the weeds out!
- If your onion seems limp, discolored, or otherwise ill, it may have a plant disease. Move your onion away from other plants and discuss its symptoms with a plant nursery worker to determine the best way to treat the disease.
