A bottle garden is sort of mini terrarium. Able to fit on a windowsill, this project can be enjoyed by horticulture enthusiasts and can also provide a useful educational experience for anyone who wishes to teach children about plant growth. Standard, wide-mouth canning jars can work well for this project, as can mayonnaise jars and wide-mouth plastic water bottles.
Trim the edges of a plastic 113gr applesauce or fruit snack container with scissors, so that it will fit inside the mouth of the jar or bottle.
Attach coordinating hook and loop fastener (Velcro) squares to bottom of the snack container and inside the jar lid. Stick the snack container to the lid.
Place a layer of gravel in the bottom of the snack container. This will provide drainage and help to prevent root rot.
Add potting soil and transplant a small plant to the container on top of the layer of gravel. Ferns, mosses and ivy plants work well, but you can experiment with other small plants.
Place the jar or bottle, upside-down, over the plant and screw on the lid.
Run a bead of hot glue on the jar, about 1 inch up from the jar lid, and attach a length of 2-inch lace for a decorative touch.
Care for your bottle garden by placing it in a warm, sunny spot and adding water when needed.
A grouping of bottle gardens can make an attractive windowsill display.
Do not place more than one plant in a single bottle garden. There is not enough soil to support a group of plants.
