Creating an outdoor plant box with a built-in lichen system is a fantastic way to blend functionality with natural aesthetics. Lichens and mosses thrive in moist, shaded environments, making them perfect companions for plant boxes in gardens or patios. Here’s a step-by-step guide to help you craft your own sustainable planter.

Materials Needed:

- Untreated cedar or redwood planks (resistant to rot)

- Screws and waterproof wood glue

- Landscape fabric or mesh

- Potting soil and peat moss

- Lichen or moss cuttings (collected sustainably)

- Drill and saw

Step 1: Design and Cut the Wood

Measure and cut the wood to your desired dimensions. A simple rectangular box (e.g., 24"x12"x12") works well. Assemble the frame using screws and glue, ensuring drainage holes at the bottom.

Step 2: Line the Interior

Cover the inside with landscape fabric to retain soil while allowing drainage. This prevents soil erosion and keeps the lichen system moist.

Step 3: Prepare the Growing Medium

Mix potting soil with peat moss to create a slightly acidic base, ideal for lichen and moss growth. Fill the box halfway, leaving space for plants.

Step 4: Add Lichen or Moss

Gently press lichen or moss cuttings into the soil or attach them to the sides using a natural adhesive like yogurt or buttermilk. Mist lightly to encourage growth.

Step 5: Plant and Maintain

Add shade-loving plants like ferns or hostas. Place the box in a shaded area and water regularly to keep the lichen system thriving.

This DIY project not only enhances your garden’s beauty but also promotes biodiversity. Happy gardening!
