How does the porosity of granite affect water drainage in outdoor tree boxes?
The porosity of granite plays a crucial role in water drainage for outdoor tree boxes, a common feature in urban landscaping. Granite, a naturally porous rock, allows water to seep through its tiny gaps, preventing waterlogging and promoting healthy root growth. However, the degree of porosity varies, affecting drainage efficiency. Highly porous granite facilitates faster water movement, reducing soil saturation, while less porous types may retain moisture longer. Proper selection of granite porosity ensures optimal soil permeability, balancing water retention and drainage to support tree health in urban environments. Understanding this relationship helps landscapers design sustainable tree boxes that thrive in diverse climates.
