In a world of pristine lawns and perfect petunias, one man is determined to cultivate chaos. Zach Galifianakis stars as Neville, a deeply misanthropic and profoundly unqualified host of a public television gardening program that is anything but serene. Convinced he is presenting a masterpiece of horticultural education, Neville instead unleashes a torrent of bizarre advice, accidental plant warfare, and simmering resentment towards his own audience. The show's central conflict blooms from the desperate attempts of the beleaguered production crew to maintain a shred of professionalism while Neville’s "unique" methods—from experimental fertilizer recipes to questionable pest control—threaten to destroy the station's reputation and the local ecosystem. This cringe-worthy comedy digs into the fertile soil of awkward humor, presenting a hilariously warped take on the calm DIY show, where the only thing guaranteed to grow is a sense of impending disaster.
