15 years ago we had a 100 foot ash tree with a 16 ft circumference taken down because it was not leafing out and was stressed. It was perched on the crest of our front hillside that is covered with ivy. The landscapers discovered that the trunk was solid, but the root system was rotted--a shovel went through the stump easily. These past three years we have noticed significant divets - 3 feet across-in the ivy with channels running downhill. The established ivy criss-crossed in many layers 6-12 inches above the soil. Some of the ivy did not survive the recent winters because of its exposure being suspended above the soil. We worked 3 yards of topsoil into the bigger divets this summer. The ivy filled in, but we are noticing the divets are back as well as the channels. Can anything be done to stabilize the hillside? 15 yrs ago we had drains put in to carry the roof runoff to the street and a concrete and brick patio on top of the hill in front of the house which ends about 6-7 feet from the biggest divet at the top of the hill.

I would recommend that you contact the Hamilton County Soil and Water Conservation District. They provide local help with soil stabilization issues.
