Terrarium making involves creating a miniature garden within a glass container. This self-sustaining ecosystem typically includes soil, plants, and decorative elements like stones or figurines. The enclosed environment allows for moisture recycling, making it low-maintenance and suitable for various plant types, such as succulents or ferns. To start, choose a clear glass container and layer materials like gravel for drainage, activated charcoal to prevent odors, and potting soil for the plants. After planting, add decorative touches and water lightly. Place the terrarium in indirect sunlight, and enjoy watching your little garden thrive over time.
