We just planted this variegated pittosporum 3 weeks ago in a mostly shaded area. Even the sun they do get is very filtered. We fertilized immediately with Lady Bug "John's Recipe" and have been watering about every 3 days while the plants get established (esp. since it's already pretty hot outside). Everything we have tried to plant in this spot doesn't seem to make it. We tried a Grecian Pattern plant (acanthus), daisy bush, liriope and now the pittosporum. We noticed the leaves curling under about a week ago and assumed it needed water. I watered it and didn't notice much change. A few days ago I added Lady Bug "Terra Tonic Super" soil activator when I watered it thinking it could be a soil issue. The leaves are curling under even worse now and I felt the soil today and it feels moist. Am I over-watering?
