Building an outdoor plant box with a built-in fungal system is a fantastic way to promote healthy plant growth while embracing sustainable gardening practices. Here’s a step-by-step guide to help you create your own:

Materials Needed:

- Untreated wood (cedar or redwood recommended)

- Screws and drill

- Landscape fabric

- Organic potting soil

- Mycorrhizal fungi inoculant

- Compost or worm castings

- Mulch

Step 1: Design and Cut the Wood

Measure and cut the wood to your desired dimensions. A common size is 4x4 feet, but adjust based on your space. Assemble the box using screws, ensuring it’s sturdy.

Step 2: Line the Box

Place landscape fabric inside the box to prevent soil erosion while allowing drainage. Secure it with staples or nails.

Step 3: Add Soil and Fungi

Fill the box with a mix of organic potting soil and compost. Sprinkle mycorrhizal fungi inoculant evenly—this symbiotic fungus helps plants absorb nutrients more efficiently.

Step 4: Plant and Mulch

Plant your chosen vegetables, herbs, or flowers. Cover the soil with mulch to retain moisture and protect the fungal network.

Step 5: Maintain the System

Water regularly but avoid over-saturation. The fungal system will thrive in moist, well-aerated soil, boosting plant health naturally.

By integrating a fungal system into your plant box, you’ll create a self-sustaining ecosystem that reduces the need for chemical fertilizers. Happy gardening!
