The world around you including plants, air, water, soil and animals makes up what is often called an "ecosystem." A terrarium is an example of an ecosystem which is closed or self-container. Within the terrarium is everything that a plant needs: soil, water and air.
- Choose the 3 to 5 plants for the terrarium from Table 1. To the container, add a 1/2 inch layer of gravel. Add a 1/4 inch layer of potting charcoal. Add 4 inches of potting soil.
- Planting is next. Using a spoon or pointed stick, open a place for each plant, set it in and press the soil back around the roots.
- Lightly water each plant. DO NOT OVERWATER!
- Close the container. If too much water accumulates in the container, it can be opened for short periods of time.
- Place the terrarium anywhere in indirect sunlight.
