I have approximately 20, four year old Pink Oleanders planted in my yard. A couple of them have the leaves turning brown in some parts of the plant and other parts of the plant looks normal. The leaves are turning brown from the tip to about half way up the leaf. I have checked the dripper and it is working properly. All of the plants are on the same water schedule. I have them watering one hour every three days right now. Do you have any idea what wold cause these two plants to do this?
