We just put in 330 pressure treated 5x5" round fence posts with oak board for horse pasture fencing. After tamping, there is a depression around most of the posts. I understand we need to have a mound above ground for water to flow off. What should we use to fill these depressions? Gravel? Sand? Soil? We'll have to haul in product, as strange as it seems, what we took OUT of the hole was not enough to fill the hole, even after the post was added.
Thanks!
