My friend Don Davis, who used to run a sizeable landscaping business, is devoting some of his considerable talents to helping create an automatic watering system for a tiny 20 square foot patch in front of my house holding agapanthus. Here he is drawing a diagram and listing the needed parts. His wife, Lynn, planted them 3 weeks ago. See http://www.pbase.com/image/28938277

My gardening experience and skills are zilch, so I am very thankful for this terrific help.
