Sunny horizontal space quickly ran out, but Sarah wanted to keep planting. "The rickety wood fence with its peeling paint seemed to mock me," she says. Inspired by a TV show on the Hanging Gardens of Babylon, she used clothesline rope to create her own mini hanging garden. "Since each hanging pot prevents those below it from getting the full benefit of any rainfall, it's important to consider water needs as well as plant height when organizing vertical space. My current garden development musings revolve around rain collection and drip-feed watering," she says.
