How do you prevent natural rattan outdoor tree boxes from absorbing harmful chemicals from soil?

Natural rattan outdoor tree boxes add a rustic charm to gardens, but they can absorb harmful chemicals from the soil over time. To prevent this, follow these steps:

1. Use a Liner – Place a high-quality plastic or fabric liner inside the rattan box to create a barrier between the soil and the material.

2. Seal the Rattan – Apply a non-toxic sealant to the interior of the box to reduce moisture and chemical penetration.

3. Choose Safe Soil – Opt for organic or chemical-free soil to minimize exposure to harmful substances.

4. Elevate the Box – Use feet or a stand to keep the rattan box slightly above the ground, reducing direct contact with contaminated soil.

5. Regular Maintenance – Clean and inspect the rattan periodically to ensure no cracks or damage allow chemical absorption.

By taking these precautions, you can extend the lifespan of your rattan tree boxes while keeping them safe and eco-friendly.
