The possible symptoms are root rot, collar, and or crown rot. All this results in poor condition of the trunk and/or foliage. The collar damage includes visible rotting or damage of the upper trunk area.
On the other hand, crown damage is shown as the leaves get pale, small, dry, and/or the growth ceases or slows down. At this stage, the roots May or May not be affected. In case of root rot, brown mushy roots will be found at the underground base.
Prevention is always better than cure. So, a monthly check on the soil, drainage, foliage health and growth rate of the tree can save your Zelkova from rot.
