20 Apr 12, (Australia - cool/mountain climate): I must be very lucky! I ignored everything the onion pack said (like covering with seed raising mixture, etc) and planted the seeds right into the dirt. Rather than the seeds taking 21-28 days as the packet said, they came through in 10 and going really strong :) All the best :)

13 Jan 12, Narelle (Australia - temperate climate): How do you get onion seeds to germinate? I've tried with a few different seed packets, but no luck. Is it the soil? I'd love some information for optimum conditions for growing onions from seed.

05 Feb 12, Jimmy (Australia - temperate climate): I raised seeds in seed propogating mix in small containers first. That way I can control watering and temperature better until they are strong enough to transplant. Have had almost 100% seed germination rate so far! Hope that helps.

05 Nov 11, wes (New Zealand - sub-tropical climate): We grew white onoins & have just harvested & are now drying in the sun. How long should they be dried ? Is it better to leave the tops on or should they be cut off to speed drying? Regards,wes.
