How to grow green onions

Regrow from cuttings

This is the easiest way to green onions as long as you have a root end you can regrow the onions. So make sure the root end is attached so they stay fresher for longer.

• Cut off the stems about an inch above the roots and place the roots in a shallow glass jar with water to keep the roots hydrated.
• Place the jar in a bright, sunny spot and leave them overnight for a few days and keep checking to see if the roots stay submerged.
• Change the water regularly to keep it fresh and after a few days, you'll notice new growth will appear.
• After a week new growth will appear and if you want them to keep growing longer, you can plant them in some soil in your garden or a container with potting soil.
• Plant them about 1 1/2” deep and firm the soil gently around and water.

Growing from seeds

• Plant the onions ¼" deep and 2" apart on loose, fertile, and well-drained soil in your garden with full sun.
• Green onions germinate slowly so it can take about 2 weeks to see any growth, but keep the soil evenly moist at all times.
• Once they’ve sprouted, water regularly and keep the area weeded. Fertilize monthly with a balanced fertilizer for optimum growth and harvest when they reach about 8 inches.

From seed in container

• Green onions do well planted indoors in any container 6” deep and placed near a bright, sunny window or under grow lights.
• Space the seeds 2" apart in the container with well-drained potting soil and make sure it stays evenly moist.
• Place the container outdoors and only bring it indoors before the first fall frost so you can grow your green onions all season.
