Spring onions that I grew from seeds resemble toothpicks for almost 2-3 months through winter. They usually "thicken up" when the weather warms up and I find after I cut the leaves (and use in my cooking), the new leaves get thicker (as thick as the one you buy) and they keep coming back.

Good to know! I'm in a cool climate (Victoria) and I've grown some from seed and they also look like spindly toothpicks... Thanks for sharing.

I planted my spring onions (from seed) roughly a month and half ago, they have only grown a tiny bit - they actually resemble toothpicks. What am I doing wrong? I live in Melbourne metro. I have the exact same problem with my leeks

This reply is a few years late, but I found it's easier to grow spring onions from healthy, fully-grown ones from a fruit market. Just cut off and keep the bottom 5 to 7cm and replant. They like a fair amount of water but good drainage, so they grow well in containers, in full sun. I tried growing from store-bought seeds and seeds saved from last year, but many didn't germinate, the ones that did took a long time to grow, and the sprouts are so tiny they can get damaged/squashed when watering if you're not really careful.

My spring onions have got seed pods - is it possible to grow new plants from these? And how should I harvest the seeds? The plants originated from off cuts from bunches I bought in the supermarket.

Let the flower heads fully open, then when the tiny black seeds are just visible, cut off the whole flower head and pop it in a paper bag, leave it open in a dry place until the flower head dries. Then when dry, you can lightly crush up the flower head and collect the seeds in the bag.

Yes you can cut the spring onion at soil level and it will grow again - even the shop bought ones!
