There is always surplus from a thriving garden and I sell plants in a small way at the end of the drive. I've met a lot of nice people and plant enthusiasts this way, though most often the plants go and the money appears in the honesty pot without me seeing anyone.
People ask if the money gets stolen. The answer is no. People are honest. In 6 or 7 years, only once did money get taken and the thief kindly put the lid back on the jar and left it at the edge of the road! - I guess they needed the £1.40 more than I did.
I've just put out the first plants of the season. They are getting a bit rain battered - but I think of Tammy in drought stricken Oklahoma, and am grateful....
