Hi Trent, I must admit that I am not sure what the cause of your problem is. Lillypillies can survive on half a day’s sun in the warmer months and none over winter, but they don’t like it. The photo looks a bit like lack of watering is the cause. Dig some small holes with a garden trowel to a depth of about 20-30cm. Look for dry soil. If you find it, get a soil wetting agent such as Scotts Everydrop and apply it to the soil. From then on, water the plants once a week in the cooler months and twice a week in the warmer months. Watering involves a sprinkler or irrigation system running for about 30 minutes on each plant. don
