Yes exactly I stated as a student trainee horticulturist gained city and guilds stages 1and2 then went on to do a Nebss retired as a nursery superintendent and believe me I did every dirt job that was asked of me even when totally qualified!maybe an employment model fault, low pay with no prospects?
There has to be a goal of promotion in any job - I moved all over the country to gain experience voted for the common market hit a blank wall abroad!
My late mother and late father told me never to go into Horticulture, and they were proud I proved the wrong - I even got head hunted for my final job!
