Trying to grow these from seed is difficult. The tiny seedlings are easy to lose as well. Honestly just buy a bunch from a shop, cut the bottoms off about an inch long them put them into potting mix. You'll have usable tops within a month. Far, far easier than trying to grow from seed. I had aso failed to grow from seed many times, and then realised I wasted my time with that. They take very readily as cuttings from mature plants.

onion seeds do not keep very well. storing in freezer improves viability. are lucky to store viable seeds for more than a year in ambient condition....check the use by date.....a good long date will improve your success. Also check variety - it helps to have local seeds from successful crop.

Like all onions they can be grown in warmer areas if you are in a frost free area of course you can plant them in containers for an early start

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
