About Garden Advice

Garden Advice came about by Bill Brett’s frustration with the amount of misleading and incorrect information in the New Zealand Garden Centre industry. Frequently when asked a question about a plant or product, garden retail staff simply read the very brief label. On checking websites of garden wholesalers, production nurseries, and garden retailers, quality information is scarce and misleading at best. Add to this garden magazines, the fairy tales of social media, and gardeners become confused.
