The 1 module of the rhs diploma level 2 with Noel Kingsbury was very good informative and felt like a proper lecture on line. The subsequent lectures supposed to be and advertised to be taken by Tom Cole where horrendous. I am sure Hillary Thomas is a superb horticulturalist but having read the principles of horticulture level 2 text book myself all she did was read from the text very few visual aids and the slides never matched up with what she said. Suffice to say I got more from the text book than I did from the 2 lectures. What they do give you is a base for self taught learning but you still need to read the syllabus to make sure you are focused on the right subjects. They are not expensive so if you are confident and able it’s better than spending a fortune on a full coarse.
