Nurseryman James Treasby has a repeat visit from a mysterious new customer, gardener Johnny Dalton is in the balmy surroundings of Mere Castle’s south-facing borders recovering from what could have been a disastrous falling-out with his employers. Meanwhile, rival gardeners Petunia and Wayne Martin are planning their own, artistic intervention for the start of their open gardens season while continuing to deal with the fall-out from their previous gardener. Johnny’s troubles are not over though, as his dealings with several of the village’s less salubrious characters are about to be exposed, as the completion of the Japanese Garden restoration is celebrated with an impromptu party.
