The plants in the greenhouse serve a variety of purposes. In addition to the beauty they add, they are good for cleaning the air and for teaching about indoor plants. Our greenhouse plants include:

Worm Composting

We are taking some of our compost to a worm bin located in the greenhouse. We got the bin from the Worm Factory. We use red worms from California that were donated by Helen Bradley. Over time, we'll be able to harvest the liquid (compost tea) that will be produced to fertilize our plants.
