When American gardeners hear the word espalier, we tend to imagine installations in the formal French style: hoity-toity, high-maintenance, and baroquely decorative. Yet the ancient technique of training trees flat on a wall or frame has its roots in space-saving, yield-boosting practicality. In this episode, Colleen argues that this charming art of vertical gardening is uniquely suited to our urban landscapes. 

First up, we talk about "pruning" our workloads. Finally, we share some listener mail about anachronistic virtual plants and the controversial transgenic American chestnut.
