How does fabric porosity affect root oxygenation in outdoor flower boxes?

Fabric porosity plays a crucial role in root oxygenation for plants grown in outdoor flower boxes. The permeability of the fabric determines how well air and water circulate around the roots, directly influencing plant health. High-porosity fabrics allow better airflow, preventing root suffocation and promoting robust growth. Conversely, low-porosity materials may retain excess moisture, leading to root rot. Choosing the right fabric porosity ensures optimal oxygenation, healthier roots, and thriving plants in your garden. This guide explores the science behind fabric porosity and offers practical tips for selecting the best materials for your flower boxes.
