Have a look at the Horticultural Correspondence college -
www.hccollege.co.uk
I know it is not the course you are looking at but I have their RHS
General and andvance courses - lots of info. They provide telophone
support and you mail in your coursework. I guess it would be the same
for the design course they offer.
