How to choose fabric thickness for optimal root protection in outdoor tree boxes?

Choosing the right fabric thickness for outdoor tree boxes is crucial for protecting tree roots and ensuring healthy growth. Here’s a simple guide to help you make the best decision:

1. Understand the Purpose: The fabric acts as a root barrier, preventing roots from growing into unwanted areas while allowing water and nutrients to pass through.

2. Fabric Thickness Matters:

- Lightweight (3-5 oz/sq yd): Ideal for small trees or temporary use. Provides basic root control but may degrade faster.

- Medium (6-8 oz/sq yd): Suitable for most trees. Offers durability and better root protection.

- Heavyweight (10+ oz/sq yd): Best for large trees or high-traffic areas. Provides long-term root barrier performance.

3. Material Selection: Opt for woven or non-woven polypropylene fabrics, as they are durable and permeable.

4. Installation Tips: Ensure the fabric is properly secured and overlapped to prevent root penetration.

By selecting the right fabric thickness, you can balance root protection and tree health, ensuring your outdoor tree boxes thrive for years.
