Put a packet of spring onions through a cold wash by mistake in a pocket. Left them on top of the w. machine a few days - they all sprouted in the packet.

I've had good result in getting spring onions to germinate from seed in spring autumn & winter but NOT summer. I have come to the conclusion that the Newcastle NSW summer is just too hot for them

how do you know when to harvest spring onions
11 Mar 11, Katherine (Australia - temperate climate)
Harvest when the leaves are tall, upright, and green. You're only eating the portion of the plant you see above the soil, so when that looks like something you want to eat, snip it off and eat it. There's no need to dig up the whole plant, just cut leaves from the outside.

do ya grow a spring onion from an seeding onion and do i just put it straight in the ground and what do u neeed to do to grow it ?

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.

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?

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
