What dose parsley like for fertilizer to max its growth in the south east QLD area?

I am interested in what you are calling the QLD area. I don't have a clue why it would make any difference in what area you grow parsley, it is an herb. Herbs don't require much fertilizer to be healthy, mine are planted in compost rich soil, in window boxes, and in just plain garden soil and there isn't much difference in the size or looks of the plants. As long as they receive lots of sun and water, parsley should be quite healthy; myl last year 's plants survived the winter and are now producing lots of seed I can use next year to plant them again.
