Lining an outdoor plant box is essential for protecting the wood, ensuring proper drainage, and promoting healthy plant growth. Here’s a step-by-step guide to help you choose the best lining method:

1. Choose the Right Material: Opt for durable, waterproof materials like landscape fabric, plastic sheeting, or pond liner. Avoid materials that trap excess moisture, as they can cause root rot.

2. Measure and Cut: Measure the interior dimensions of your plant box and cut the lining material to fit snugly. Leave a few inches of excess to fold over the top edges for added protection.

3. Secure the Lining: Use staples or waterproof adhesive to attach the lining to the interior walls. Ensure there are no gaps where soil or water can escape.

4. Create Drainage Holes: Poke small holes in the bottom of the lining to allow excess water to drain. This prevents waterlogging and keeps roots healthy.

5. Add a Layer of Gravel: Place a thin layer of gravel or pebbles at the bottom before adding soil. This improves drainage and prevents the lining from clogging.

By following these steps, your outdoor plant box will stay sturdy, well-drained, and ready to support thriving plants. Happy gardening!
