How to make and care for one.

A terrarium is a tiny plant world under glass. You can make it with plants you find in the woods. Once you make it, it needs little care, just a little water now and then.

Put a 1/4 inch-deep layer of granular activated charcoal on the bottom of a wide-mouth jar - a large peanut-butter jar works well. The charcoal will absorb the acid produced by the plants as they grow. Without it, your terrarium won't last more than a few months. Next put down a 2-inch layer of sterilized packaged potting soil, mixed with packaged humus. Dampen the soil. Add the plants, burying their roots in the soil. Put the lid on the
jar and place in light, but not direct sunlight. If there is too much moisture inside, open to dry a little. Water one teaspoon each week.
