Given enough time and planning we can add a large stone underneath the root layer of a freshly planted tree (usually best for sapling trees that do not already have a large root foundation). This particular method can be utilized greatly in arid climates and underneath dwarf trees that are used in the urban and suburban environments. The placement of a large stone under the roots will passively and gently force the tree to spread it’s roots over larger horizontal surface area giving the tree a more firm footing and a more desired water catchment retention area. The stone will also aid in the regulation of temperature at the root layer due to it’s thermal mass and create mild condensation every night in which the roots will benefit water from. It is also wise to note that raw nutrient comes in the form of rocks. In essence we are giving the tree a nutrient trap.
