    Place the roots in water and wait until they start to develop new white root growth. Then, you can transfer them directly into soil.

    Yes, they are easy to regrow. Simply take the bulbs with the roots attached and place them, roots down, into a small jar or cup. Place the cup in a sunny area and submerge the roots for about a week. At this point, you should start seeing regrowth.

    Spring onions will produce edible stems about 4 or 5 times after you snip them off the first time. Onions are perennial, so they will regrow each year as long as they're healthy.

  • Question
    How much phosphate does spring onion need?
    Community Answer
    Be very careful using phosphate or nitrogen. You could end up with all green and no onion bulb or sending them to seed way too early. If you do use it, apply only a very small amount.
  • Question
    How long do spring onions take to germinate?
    Community Answer
    All types of onion seeds can take up to 10 days. Some varieties, a bit longer. Don't try to hurry them up by applying warmth, as in a heated germinator. Cool germination is much better.
  • Question
    Can spring onions be planted in water on top of pebbles in a glass jar in the windowsill?
    Community Answer
    Spring onions should be planted in dirt. Your method includes too much water.
  • Question
    I planted onion sets last autumn and this spring they looked like smaller 'spring onions', is that what 'spring onions 'are? Or are they a particular variety and should I eat mine or not?
    Community Answer
    They should look like small green stalks, similar to a green onion or scallion.
  • Question
    What is the harvesting period after sowing?
    Community Answer
    The old wives tale is plant on the coldest day of the year and harvest before the hottest day of the year. In other words, plant your onions soon as the climate/soil is cool enough and harvest before the heat of summer.
  • Question
    What do I need to plant a spring onion?
    Community Answer
    Either start them off from seeds or buy seedlings/sets. Then plant them out when they are large enough into unfertilised soil.
  • Question
    Should I wait until after the spring onions flower to cut the tops?
    Community Answer
    No, if you leave it to flower, then the flavor and the nutritional value of the spring onions will decrease.
  • Question
    Can I grow spring onions from onion seeds? If so, will I need a large amount of room? I live in an apartment.

    Community Answer
    You can, and the amount of room needed depends entirely on how many plants you're planning to grow. One spring onion plant will grow to maturity quite happily in a 2-liter plant pot.
  • Question
    Would organic fertilizer be good for spring onions?
    Anton Skipworth
    Community Answer
    Spring onions generally tend not to require much in the way of fertilization. With that said, organic fertilizers are recommended if you are going to fertilize. If you're worried about nutrient intake because of dry soil, you may want to try a mulch before you apply fertilizers, as mulches are good at retaining moisture.
  • Question
    Do I need to dry spring onions before planting them?
    Community Answer
    No. You don't need to dry the bulb before you re-plant, it can be planted as it is.
