THE HOUSE PLANT EXPERT
A botanist and soil scientist, Dr Hessayon was working for Baby Bio when he dreamed up the Expert series and promptly became the best selling non-fiction author in the world. Since 1960 this one has sold an amazing 15 million copies. Basic yet brilliant there are just simple drawings, charts and concise words lacking in any fluff whatsoever. The Guardian described the look as ‘1980s East German tourist brochure but without the exuberance’. But the raw information is there at your fingertips, they were the YouTube how-to videos of their day and early on in my career were always my first point of reference.
