How does canvas fabric compare to geotextiles for drainage in outdoor tree boxes?

When selecting materials for drainage in outdoor tree boxes, both canvas fabric and geotextiles offer unique advantages. Canvas fabric, typically made from cotton or polyester, provides moderate permeability, allowing water to pass through while retaining soil. It is durable and biodegradable but may degrade faster under constant moisture.

Geotextiles, engineered specifically for drainage and filtration, excel in water management. Non-woven geotextiles offer superior permeability, preventing soil clogging while promoting root aeration. They are UV-resistant and long-lasting, making them ideal for high-moisture environments.

For tree health, geotextiles are often preferred due to their consistent performance in heavy rain, whereas canvas may suit temporary or low-budget setups. Proper installation and layering are crucial for both materials to ensure effective drainage and root development.
