How to prevent eucalyptus wood outdoor flower pots from leaching chemicals into soil?

Eucalyptus wood is a popular choice for outdoor flower pots due to its durability and natural resistance to pests. However, untreated eucalyptus can leach chemicals like tannins into the soil, potentially harming plants. Here’s how to prevent it:

1. Seal the Wood: Apply a food-grade or non-toxic wood sealant to create a barrier between the wood and soil. Look for products labeled as safe for gardening.

2. Use a Liner: Insert a plastic or fabric liner inside the pot to prevent direct contact between the wood and soil. Ensure it has drainage holes.

3. Cure the Wood: Let the wood weather naturally for a few weeks before planting. This reduces initial chemical leaching.

4. Choose Treated Eucalyptus: Opt for heat-treated or kiln-dried eucalyptus, which has fewer residual chemicals.

5. Monitor Soil pH: Regularly test soil pH and adjust if needed, as leaching can alter acidity levels.

By following these steps, you can enjoy the beauty of eucalyptus wood planters without compromising plant health.
