Hello. Just signed up and hoping someone out there has dealt with our problems successfully. We have 10 acres in Willcox, Az, which was primarily garbage and sparse desert vegetation growing on an ancient lake bed. While Mesquite and bunch grass is the main vegetation, and the top soil is sporatic at best, we have good water and high hopes. The biggest problem we have is limited drainage in many places... clay and sometimes what appears to be sand stone below 2 feet. However, we have found some places with excellant drainage (for tree planting) and at 6 ' in one area we unearthed what we assume are yellow sands of an ancient streambed. The problem is we have run into areas where even when we dug 10 feet down, we could not get drainage. Interestingly enough, about 2 feet from top, above the water impenetrable level, there is a root zone that does drain. We are thinking of going with Mulberry trees since they only require 2' of drainage. Anyone else run into this problem? Should we 'go with the flow' instead of fighting, or keep looking for the deeper areas that do drain?
