Terrariums are easy to make and simple to maintain. They are also great gift idea or party favor. Today we have gathered for you 20 Adorable DIY Terrarium Ideas. Start with a clean and dry glass vessel. Add a layer of rocks along the bottom for drainage, about an inch deep. Next add a thin layer of charcoal to keep your terrarium’s environment healthy and mold-free. A layer of soil comes next, though you can add a layer of small rocks first for a little more visual interest. Be sure to leave enough room for plants when adding the soil, and keep the leaves away from the glass. Place the terrarium in a spot where it will get indirect light and give your terrarium a light watering. For additional tips visit the link below each DIY project.
