Is it okay to start sowing the kohl rabi seeds now or should I wait for a couple of months and start in August? I live in suburban Sydney

Go to the kohlrabi page, set climate to sub tropical, ( eg www.gardenate.com/plant/Kohlrabi?zone=3) and read the calendar months when to plant. P in a green box means Plant or Sow seeds.
