Bottle gardens add indoor greenery all winter long

From The Fairbanks Daily News-Miner, Tuesday, November 23, 2010:

Are you missing the green of your garden? Grow a garden year-round with a bottle garden.

A bottle garden, also known as a terrarium, is a self-contained, closed system that sustains itself much like Earth’s atmosphere. Photosynthesis and decomposition occur in a balanced state, creating an environment that requires minimal care.

Bottle gardens enable you to grow plants that require high levels of humidity, which can be difficult during the dry winter months in your house. It is an excellent option for the Fairbanks gardener.

You will need a glass container, small rocks, activated charcoal (available in the aquarium section at the store), sphagnum moss, potting soil, a few complementary plants that have similar growing requirements, and a spoon or tool that can reach into the jar.
