spring onions are best planted out or in sown in late March to early May.

Just a note : I always put my scraps and off cuts into the compost heap and i found big spring onions growing all over the place turns out my spring onion off cuts grew another spring onion. I tried planting the off cuts of of some shop brought onions and now i have an endless supply and just cut them 50mm above the ground.

Jared - My spring onions are still seedlings so I bought some from the shop. I looked for roots that were not dried out. I planted them 1inch into the ground and they have been growing new shoots for over a month! When I need some I either cut off a green stem for garnish or pull it out of the ground to cook with. Better than in a cup of water for 1 week!

when a recipe says to use spring onions, how do I know whether it means green onions, or shallots? The difference? thank you

Spring onions and shallots are two different things. Shallots (also known as French shallots) are like smallish onions (just a bulb) whereas spring onions don't have a big bulb and include the long green shoots (leaves). I think spring onions are called green onions in the US.

I have been growing spring onions for a while and have just noticed bubble like flowers om the tips of some stems. Should I be cutting these off???

Spring onions in Victoria are known as shallots in NSW. Very bloody confusing. As a cook, I wouldn't worry too much about it unless in Asian cuisine when the long skinny ones with green bits (Victoria vs NSW ... again! ...hehehe) are preferred.

A simple suggestion for would-be spring onion growers! Instead of all the cost, hassle and time that it takes to get a crop of spring onions from seed, I just buy myself a bunch of thin spring onions at the supermarket and plant them 3 inches apart in well mulched and limed soil. The last bunch I bought had 45 plants which I planted yesterday and will be ready to progressively use in 10 days time, when they have thickened a bit, for some 4-6 weeks. It's fool proof and guaranteed to give you an instant spring onion patch. Even though it may be cheating a little. Cost $1.99 compared to $4.95 for a packet of seed.

I have trouble growing spring onions from seed. i plant them directly in the ground and also in a mini greenhouse using seed raising mix. both plantings don't seem to produce. WHY?

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.
