How does the porosity of fabric affect fertilizer leaching in outdoor pots?
The porosity of fabric used in outdoor pots plays a critical role in fertilizer leaching, directly impacting plant health and nutrient efficiency. Highly porous fabrics allow water and dissolved fertilizers to drain quickly, reducing nutrient retention in the soil. Conversely, less porous fabrics retain moisture and nutrients longer but may risk waterlogging. Optimal porosity balances drainage and retention, ensuring plants receive adequate nutrients without excessive leaching. Choosing the right fabric porosity can enhance plant growth while minimizing fertilizer waste and environmental runoff.
