Green onion also called spring onions are very easy to grow. Growing them from seeds can take a long time but it doesn't have to too. In this Instructable you can see how easy it is to grow.

All that is needed is some left over green onion cut offs from store bought green onions. I like saving all the cuttings and I ended up with a whole garden of green onions. They will pay for themselves over and over for something that was going to get thrown out or composted.

You will need:

Green Onion Cut Offs
Soil
Stick

Step 1: Planting and Growing the Green Onions

Using the stick poke some holes in the soil and insert the green onions in the soil. They can be planted close together, keeping them spaced around 2 inches apart from each other.

Green onions will grow in any soil conditions and are very hardy, they will grow even if the temperature is cold, as long as it's above freezing. They will grow indoors in the winter as long as they get a few hours of sunlight. Plant them outside once the last snowfall has melted. After about 7-10 days of growing, they will be ready for harvest.

When harvesting, leave a few inches of the green onion so they regrow. You can keep cutting them down and they will keep re-growing over and over. An endless bounty of green onions!

Check out this video on the whole process and a really cool time-lapse of the green onions growing over a period of a few days.
