In this episode of "A Rich Spot of Earth" we talk about water: how water was collected and used at Monticello and how to properly water your own plants. We also discuss some of the plants sent back to Jefferson from the Lewis and Clark Expedition, and spend a few minutes on the American Chestnut, the severely endangered native tree that is making a comeback thanks to the efforts of the American Chestnut Foundation (www.acf.org)
