We have a large Ash that is roughly 20 to 30 years old. I am noticing that the ground around the base is rising and, about five to seven feet out, the ground, by contrast, appears to be lowering. This has slowly been happening over the last 3-5 years. What should we do?
This could be a sign of root and/or soil failure. If this is the case, then the tree would need to be removed. Some things to check: is the soil "soft" where the ground is rising? Is the tree leaning more now than three to five years ago? Was there any trenching done around the tree (i.e. roots cut)? This is very uncharacteristic of ash trees, usually they drop large branches, but that doesn't mean its impossible. We would need to look at it to be sure. You can click here to make an appointment.
