Can anyone help? I have planted a hedge of Podocarpus Macrophylla in my yard in St. Augustine, Florida (North eastern Florida). One side seems to be doing find, the other side continues to die branch by branch, plant by plant. All plants are in well drained, sandy soil in full sun. I have replaced several plants 4 times with the same result. Leaves start to yellow, then the branch, then the whole plant. Nothing on the internet seems to give a clue as to what is happening in this specific area. Any ideas would be greatly appreciated.
