Every desert gardening problem —salt accumulation, pH extremes, mineral deficiencies, wind erosion— traces back to one root cause: evaporation without transpiration.
When water evaporates directly from soil, capillary action pulls subsurface salts to the surface, pH rises to toxic levels, and vegetation can't establish.
But when trees and shrubs transpire water, they keep salts at depth, stabilize pH, and create conditions for other plants to thrive.
One intervention that triggers a cascade of benefits that transforms hostile desert into productive oasis.
