Growing Green Onions From Seeds:

how to grow green onions at home
  • Pick a spot in your garden that has full sun and that drains the soil well.
  • Set the soil to a depth of about 12 inches and work with compost or other organic material to add nutrients to the soil.
  • About 4 weeks before the last frost, sow the seeds directly into the ground about 1/2 inch deep.
  • Space each row about 1 foot apart.
  • If you live in a cold climate, you can start the seeds indoors and then transplant them outdoors once the weather warms up.
  • Once the seedlings have grown, thin them 2-3 inches apart if necessary.
  • Mulch around the seedlings to keep the soil moist and prevent weeds from sprouting.
  • Water well after planting and about 1 inch each week thereafter.
  • Harvest once the shoots are about 7-8 inches long. This should take 3 to 4 weeks.
  • To harvest, you can either remove the entire plant or cut the base, letting the white in the ground grow more onions.

Growing Green Onions In Pots:

  • If you are growing indoors, follow the same conditions and place the pot on a windowsill where the plant receives at least 6 hours of sunlight per day.
  • Harvest when the green leaves are 7-8 inches long.
  • To harvest, you can either remove the entire plant or cut the base, letting the white in the ground grow more onions.
