The eccentric, stilted presenters on Gardening Australia are a big part of its appeal. These aren't heavily-styled television stars but endearing, ordinary-seeming men and women who are passionate about dirt, roots and leaves. They make for an unspectacular but comforting viewing experience.
The guests featured in tonight's episode - including a market gardener who has been tilling the same patch of soil for more than 60 years and a Vietnam veteran who has found therapeutic power in building a community garden - are more interesting than their gardens.
Indeed, host Costa Georgiadis's beard is about the lushest growth to be seen on screen. The plants and gardens are oddly underwhelming.
