planted too early, too much fertilizer. also, the Barossa is a temperate climate not subtropical, you want to treat your plant for the climate its in

Maria I think Dec is a little too early for the cooler temp leaf veg. I'd sow seed now,still warm enough to germinate or buy a punnet of seedlings which are more advanced. Plant them out keep the water up to them while young and they will go.Good luck Kev

Once you pick the broccoli, does it grow another head, or do you just take the whole plant out, after first harvest.?
