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

You can grow the ends of all types of onions simply leave a little bit of flesh above the the root and plant in pots or garden they grow best in season but will grow any time. Use as a green onion and cut and come again.

I agree with Tracey, even up here in the Macedon Ranges spring onions can be grown from seed during any of the warmer months SUGGEST see Chives for planting season

I am growing onions and spring onions with Pea's but I notice your web site says these mixes should be avoided, why is this?

Hi Jim, Spring onions are grown from seed, not a seed onion (I assume you mean onion set?). I notice that the Gardenate guide says to sow Aug through October in Temperate regions, but my experience (Melbourne) is that they can be sown pretty much all year round (obviously they grow faster in warmer conditions). I just put in some more seeds the other day. One thing worth knowing is that onion seed doesn't store very well, so if you have an old packet you might get poor germination.
