03 Jul 17, Paris (Australia - cool/mountain climate): I'm about to start growing onions from seeds and it says keep them under cover until early spring when they are ready to be planted out, I'm just wondering exactly what undercover means. Does it mean inside undercover or just out of direct sunlight outside. "Undercover" is very vague and I don't want to mess these up.

04 Jul 17, Liz (New Zealand - sub-tropical climate): When we say 'undercover', we mean somewhere which will not have extremes of temperature and cool down at night. e.g on a covered deck : or in a cool greenhouse.

12 Jun 17, Margaret Shaw (Australia - temperate climate): I have planted about 100 spring onions about 2 wks. ago, all looking good, do they benefit from any fertiliser during the growing period. I dug in a small amount of compost before planting. Thanking you, Margaret.
