Planting table onions (known as scallions, green onions) will grow well from sets in many climates. The small onion bulbs are known as sets. These onions will tolerate light frost so you can plant them fairly early in the year.

You don't really have to plant them in a certain manner. Because you will be harvesting them before they become to crowded.
============================================


Step 1
As you turn over the soil in your garden to a depth of 8 to 12" inches. You need to add compost in a ratio of about 1 to 1 into the soil and mix it thoroughly . Your soil pH should be between 5.5 to 7.0. Onion sets have shallow roots systems, so be sure to remove all grass and weeds prior to planting. This will ensure the onion sets will thrive and not have to compete with other roots.


Step 2
I like to use a tiller in the soil and when I have the soil loosened and mixed thoroughly, I will dig small holes with a salad fork that I found. It's just about the right size to form the holes about 1 to 2" inches in depth and about 1" to 2" inches apart. Depending on how much you have to plant. The salad fork will not compact the earth while digging and planting.

Step 3
You will need to sort your onion sets by their size. Onions smaller than a 1/2" you should set aside because these can be grown into larger onions. The onions larger than this should be planted because these onions will often form a seed stalk. Planting bulb sets to early when it's to cold will cause them to produce seed stalks also. This is according to Texas A&M University Extension.

Step 4
Plant an onion bulb in each hole, pointy side up. Cover over with soil and pat it down lightly.

Step 5
It is important to water onions regularly, but don't over water them. If water starts to pool or it takes a long time for the water to be absorbed, this is a sign to stop watering. Then you should start seeing your onion shoots in a couple of weeks.

Step 6

Harvest table onions anytime after 2/3rds of the tops have fallen over, according to Texas A&M University Extension . Larger table onions will have more intense flavor. Harvest fresh just before you want to use them for best taste. All parts except the roots are edible.
