22 May 20, Anonymous (South Africa - Summer rainfall climate): Gardenate suggests you plant Feb to April. Try planting it in August and it probably won't even germinate. Most plants have a defined time of the year to grow in a particular climate zone.

10 Aug 19, Sam (South Africa - Summer rainfall climate): I just planted onions that got spoiled and started to grow but now each bulb has grown into a set of seedlings. Do I pull them out and plant them separately or leave them grow as they are? Kind Regards Sam

13 Jul 20, Elizabeth (South Africa - Summer rainfall climate): Leave them to grow. Pulling apart will break the roots. A group of onions bulbs will develop and you can harvest them together or one at a time by twisting one gently.
