07 Oct 18, Mike (Australia - sub-tropical climate): I grew onions for the first time this year. Mixed success. White ones. Some formed bulbs some didn't - good health plants - probably too much N. Onions can take 6-8 mths to grow.

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?
