23 Apr 18, hennie (South Africa - Summer rainfall climate): typically root vegetables such as onions,carrots and beetroot can be grown year round , just ensure they have enough deep soil , and keep an eye on the moisture levels, after the bulbs started forming , and give them ample space between each plant , thinning is an essential function.

02 Mar 18, Leigh (New Zealand - temperate climate): Hi, I’m having fun growing potatoes, Kumara and even sweetcorn that have sprouted in the bottom of my pantry. Wondering if the same should work with a brown onion that has sprouted greens out of the top?

22 May 19, Mark Taylor (New Zealand - temperate climate): Onions are hardy plants and so frost tolerant, they will survive the winter. My understanding is If you plant them in Autumn you can harvest them in spring as spring onions but you won't get bulbs. They need to be planted in the spring for them to develop into onion bulbs. This is because bulb formation only starts after the summer equinox when the days start to shorten.

26 Feb 18, Mike (New Zealand - temperate climate): If you sow now you would transplant in 6-8 weeks. I think onions can handle some frost. Check on the net about this.
