Other Comments:
I planted the 17 Back Yard Bliss to form a hedge along the front of my garden. Ever since planting the plants at the northern end have grown faster and healthier than the southern end, the variation is very visible and gradual from one end to the other.

Thanks so much for the photo Roger: this enables me to help you much better. Note that the lawn is less green in that area too! Clearly that end of your front garden gets way less water. Investigate why it is so dry, I suspect that your irrigation system is not good enough. You could double the number of sprinkler-heads in that area?? Then make fork holes in the soil every 10cm, right throughout the area. Get some Saturaid and apply it to that area, ie around plants 1-10 from the left? Then put on a sprinkler to cover all of that area for 1 hour every day for 3 days. They could recover quickly, but being Autumn, it may take until November or December to see strong results. Water 1-10 preferentially in future. Lillypillies need lots of water: they are rainforest plants. Good luck, Don.
