Scorch on Oak

A customer brought in a sample of some of his oak tree leaves which have been discoloring annually along the edges. He went on to explain that the plant’s location was once backfilled with lime stone and other various rocks to help give a solid foundation before soil was laid (in this case, about 20″ of soil was applied) so a structure could be built. There is also about 10 feet between the tree and a waterway.

Oaks have a deep root system. As his tree continues to mature, the roots will continue to grow as well – the problem is that now his tree has an obstacle in the way of healthy root development and is now developing symptoms of scorch.  For his situation, a maple would probably serve this location better.
