Landscaping the back yard in our new house, the landscaper brought up the dirt level. But now the dirt level is so high soil is up against our fence covering 6-8" of it vertically all around the yard. I'm worried about moisture damage over time. The fence is redwood, and while it's pre-treated, that's a lot of dirt sitting up against it.
Should I pull the dirt away from the fence and either put plastic or river/pebble rocks in the gap so the soil touches one of these instead of the fence directly?
