You posted this in the Investments forum so do you mean that you want to invest money into this (where somebody else is actually doing the hands on work) or you actually want to become an apple farmer yourself?
To be honest, either way, making such an investment decision (or any decision really) based on one TV programme seems very capricious. Why do you think that this, of all things, is the most suitable investment for your overall financial and personal circumstances? Especially when, by your own admission, you have no clue about it?
