Geothermal Heating and Cooling System

Edible Forest Gardens

The two-volume book Edible Forest Gardens by Dave Jacke with Eric Toensmeier explains the approach we're going to use for growing food at the Glenn Retreat. Our food 'garden' will be seamlessly incorporated into the woodland landscape.

One of the fruit trees we're planing to try is the Paw Paw tree. The fruit tastes like a combination of banana, pineapple and mango.

How to manage a wet site
