So he told you that he didn't like people that had studied, but then actually told you to study for C&G? He then taught you about plants (with the entire situation sounding a bit Yewtreey) and put you in charge of a bunch of people mowing lawns?
I mean, it hardly sounds ground breaking. You were an apprentice gardener that watched over people doing casual work in the summer. I did the same working at the same time as being at University, albeit not as a gardener.
Totally incorrect anyone can push a lawn mower -
It was groundbreaking for me to supervise 10 young lads in another part of the nursery aged 21 being observed on the work I got out of them and the commeraddy I built up in team work .... He told me if you read my original post get your City & Guilds but learn off me in fact he told me from day one ever never say it should be done the college way , but his way -he was spot on the London City and Guilds 1 & 2 a 4 year course day release and block release was 90% theory.
I was in the same place as Roy Lancaster in Preston Myerscough Horticultural college - I was asked to do a HND - I rightly turned it down as I found out in future interviews they wanted to know what I could propagate my many qualifications by then were just a nod of approval not a big chat or a slap on the back as well done.. in fact one interview I had a plant identification test before my interview 30 out of 30 I scored knew them off by heart & thier families top of my class in Botany - it was all about my experience working under the best tree , and shrub plant propagator I had ever seen - I went on to train many apprentices in that manner as I got promoted - The person I was originally tutored off his colleague of that era became Liverpool Parks superintendent, it never bothered him, because I probably knew he was better than him practically - I ask you this who do you want to landscape your garden a person like me if I was young and fit enough - or a bookworm........
The guy who did get the Liverpool parks superintendent's job was a great horticulturist as he was trained by my boss.........
Firms tried to headhunt him - that happened to me later on in life........ gaining the IOH letters after my name which I rarely mentioned....
I am now retired -so as the saying goes don't try to tell your granddad how to suck eggs......
