Empty wine bottles can be used in the garden for decorative and practical purposes. You can bury them halfway in the ground to create colorful borders or pathways, hang them as lanterns with LED lights, or turn them into unique plant watering devices by filling them with water and inserting them upside down in the soil. Wine bottles also make creative bird feeders, garden markers, or vertical planters for small herbs or succulents. These ideas not only add character to your garden but also repurpose glass bottles, promoting recycling and sustainability.
