Building a rot-resistant outdoor plant box is a great way to enhance your garden while ensuring durability. Here’s a step-by-step guide to creating a sturdy, long-lasting plant box:

1. Choose Rot-Resistant Wood: Opt for naturally durable woods like cedar, redwood, or pressure-treated lumber. These materials resist moisture and decay, extending the lifespan of your plant box.

2. Apply a Protective Finish: Use a water-resistant sealant or outdoor-grade wood preservative to shield the wood from rain and humidity. Reapply every few years for ongoing protection.

3. Elevate the Box: Place the plant box on bricks or feet to prevent direct contact with damp soil, reducing the risk of rot.

4. Ensure Proper Drainage: Drill drainage holes in the bottom to avoid water accumulation, which can lead to wood decay.

5. Line the Interior: Add a waterproof liner (like landscape fabric) to create a barrier between the soil and wood, further preventing moisture damage.

By following these steps, your outdoor plant box will stay rot-free for years, making it a perfect addition to any garden. Happy building!
