On one of my commercial prop I have several crepes that are close to the road. On two of these (they are not next to each other), they leaves are turning yellow and/or brown(could be going into dormacy though), but near the base of the trunk they are black. Somewhat like a mold. I have done a search but I can't find out what is wrong. I think they may die. Does anyone know anything about this? Is it wetfeet? The place is irrigated. They have not been sprayed with anything neither have they been ferted with anything other than what they got from the lawn fert.
