Building a Soda Bottle Vertical Garden

Materials

• Lots of Soda Bottles
• Plants of choice
• Sand
• Potting Soil
• Binding Wire

Tools

• Scissors
• Garden Trowel
• Cutter

Instructions

Step 1: Prepare the Soda Bottles

• Use the cutter to carefully cut the bottom off each soda bottle. The size of the opening will depend on the size of the plants you intend to grow.
• With scissors, make small drainage holes in the cap of the bottle. If the bottle will be hung upside down, these holes will allow excess water to drain. If the bottle will sit upright, remove the cap.
• Optionally, you can also cut a small window in the side of the bottle for additional planting space.

Step 2: Add Drainage Material

• Place a small amount of sand at the bottom of each bottle. This helps with drainage and prevents soil from washing out of the bottle.

Step 3: Add Soil and Plants

• Fill the bottle with a mix of potting soil and sand, leaving enough space at the top for your plant.
• Use the garden trowel to transfer your plant into the bottle. If planting seeds, follow the seed packet instructions for planting depth and spacing.
• Gently press the soil around the roots or seeds to secure them.

Step 4: Secure the Bottles

• If hanging your garden, use the binding wire to securely wrap around the neck of the bottle. Make a loop with the wire for hanging.
• For a wall-mounted garden, make holes on either side of the cut-out portion of the bottle and thread binding wire through these to create a secure loop for mounting.

Step 5: Arrange Your Garden

• Decide on the layout of your vertical garden. This could be a single column of bottles or multiple columns for a larger garden.
• Hang or mount the bottles in your chosen location, ensuring they receive adequate sunlight based on the plants you’re growing.
• Consider placing bottles at different heights to create an aesthetically pleasing arrangement.

Step 6: Watering

• Water your plants according to their needs. The small size of the bottles means soil will dry out faster, so regular checking is essential.
• Use a watering can with a long spout to target water directly to the roots, minimizing waste and evaporation.

Step 7: Maintenance

• Regularly check your plants for signs of pests or disease. The close proximity of plants in a vertical garden can sometimes encourage the spread of issues, so early detection is key.
• Prune and deadhead flowers as needed to encourage growth and maintain a tidy appearance.
