Picture the scene: a visit to the beautiful Ness Botanic Garden, on the Wirral, on a pleasant morning in June. Baby safely installed with Daddy daycare. There bright and early with the whole day ahead to enjoy. Sounds marvellous doesn’t it? Just one problem: I’m there to sit exams for an RHS Level 3 qualification in Horticulture. So really, why am I doing this to myself?
