(Best months for planting Spring onions in New Zealand - cool/mountain regions)


  • Easy to grow.
  • Harvest in 100- 150 days
  • Sow in garden. Sow seed at a depth approximately three times the diameter of the seed.
  • Best planted at soil temperatures between 10°C and 20°C.
  • Space plants: close together

Can be grown from 'sets' ie seedlings brought on earlier. Spring onions are young onions grown close together and harvested before fully mature.

Do not like to be too dry. Sheltered, sunny spot. If you are growing onions from seed, you can use the 'thinnings' as spring onions

Culinary hints - cooking and eating Spring onions

Alexa, it has been a severe winter so it's not surprising things are slow. But I think you were too early with the spring onions. Did you put compost or blood and bone down before you sowed. My garden (Nelson but still cold) was a converted flower garden and I had to really work in a lot of compost to get the soil fertile again. Mitre 10 Results compost is much better than the likes of W'house stuff too.

I've set up a new garden and transplanted my spring onions along side my carrots but I'm unsure how close they can be from them

Hi, first-time gardener here! I've grown some spring onions from seed, sown in Jan, moved them to pots and now to a raised flower bed. They seem to be growing ok but according to the packet they sholud be ready to harvest just about now (70 days) - they don't look ready at all. So a few questions!: How much of the spring onion will be visible above the ground? Did I plant them at the wrong time of year? (according the packet -a ll year round is fine, according to this website only sowing Jun-Aug) Having planted in Jan - when might be a good time to harvest? Any help gratefully received. Thanks!

A local primary school did a vegetable garden project last year. When asked what they would do for better results next time, the answer was "move the plot into a sunnier position".

Have never grown any vegetation in my life before, but have some onions seemingly coming along quite nicely. EWhen they seem to be mature and ready for use, is there anything left that can be regrown next year? and if so how should I treat whatever remains and might be useful?.

my garden got into a slight state of confusion and I suspect I have some "spring onions" with big beautiful seed heads on them. The seeds look very tiny - will they self seed back into my raised beds? Or should I clip them off and dry them out? Will the roots be edible?

THE EASIEST METHOD TO GROW SPRING ONIONS in your garden the for the first time, is to buy a healthy bunch from the supermarket, cut straight across the bunch with scissors, keeping them tied together, so there is only the white part left, place them in a jug, next day plant in the early morn or late after, in a sunny place, and whalla, healthy big spring onions. Chop each green growth down to the white, as needed.

I have spring onion seeds given to me and am very interested in all the comments I have read here. I live in Tokoroa where we can have very cold temps in winter so think I will plant them late October. (We have had frosts as late as early December). Wish me luck!

I have been given some spring onion seedlings. It is early August and I wonder if it is too soon to transplant them into a pot in a sunny position. Should I just wait.... Until when? I live in Christchurch. Do frosts matter for spring onions.
