6. Plastic Bottle Planters and Hanging Gardens

Plastic bottles can be cut, reshaped, and painted to create planters for herbs, flowers, and indoor plants. They are affordable and accessible materials for eco-friendly gardening.

For tabletop planters, cut bottles horizontally, paint them, and add drainage holes. For hanging gardens, cut bottles vertically, thread rope through the ends, and hang them against a wall or balcony.

You can also cut the top half into petal shapes for a decorative planter design. Plastic bottles can be painted in earthy tones or bright colors depending on your style.
