Can be grown from 'sets' (seedlings brought on earlier). Spring onions are grown close together and harvested before fully mature.

29 Apr 20, Peter Minchin (New Zealand - temperate climate): I have grown spring onions from seeds for years, but mine are never as long as those I see in the shops. I have been transplanting the seedlings, when about 10cm high, into a shallow row , filling the row in and watering well. Should I be planting them like I do leeks, into a deepish hole with the leaves just extending out of this hole?

30 Apr 20, Another gardener (New Zealand - temperate climate): I grow shallots, far easier to grow. Plant 3 bulbs together 150mm apart, good rich soil and water each day or two. Plenty of sunlight. Easiest thing to grow I reckon. You keep some bulbs from one year for the next year. If you want to stick with spring onions try what you are thinking, don't plant too deep though. Hill the soil up a bit as they grow. Make sure you have good rich soil. The plants will show you, if weak and pale green, they need some N.
