Lining an outdoor plant box is essential to enhance its durability and protect it from moisture, rot, and pests. Here’s a step-by-step guide to help you achieve a long-lasting setup:

1. Choose the Right Material: Opt for waterproof liners like pond liner, heavy-duty plastic, or landscape fabric. These materials prevent water damage while allowing proper drainage.

2. Measure and Cut: Measure the interior dimensions of your plant box and cut the liner to fit snugly. Leave extra material to fold over the edges for added protection.

3. Secure the Liner: Use staples, nails, or waterproof adhesive to attach the liner to the interior walls. Ensure there are no gaps where water can seep through.

4. Create Drainage Holes: Poke small holes in the liner’s base to prevent waterlogging. Cover these holes with mesh to keep soil in and pests out.

5. Add a Protective Layer: Place a layer of gravel or pebbles at the bottom before adding soil. This improves drainage and further safeguards the liner.

By following these steps, your outdoor plant box will stay sturdy and functional for years, even in harsh weather conditions. Regular checks and minor repairs will extend its lifespan even further.
