There are hundreds of new growers on this web site and thousands? tens of thousands? who watch GW to be educated. So, in my opinion. for the £45,000 an episode + they should be trialling these ideas and presenting ones that work.
If I took over a plot covered in couch then I'd spray with glyphosate or, if I really wanted to be totally organic, cover with carpets (oops they're not organic anymore) sheet plastic to kill off the couch.
Making out you can get away with rotovating couch is plain wrong. It will give people the idea it's just some fuddy duddy rule to break and then they'll be swamped with the stuff and give up.
I get really cheesed watching people take on plots with high horse organic principles they don't understand which end up with them giving up and someone new coming along to take over the weed infested solid plot.
Part of me feels sorry for them and part is annoyed because they can't be bothered to research properly and certainly won't listen to anyone else.
Organic is good and laudable but please, don't pretend it's not hard work - harder initially than chemical. I believe in explaining the options honestly and allow people to make an informed choice.
As for shapes and so on - the objection to his large raised beds is that the whole concept is based on being able to cultivate without walking on them and compacting the soil. Nothing wrong with triangles and knots or anything as long as the practicalities are complied with.
Good design complies with the rules and then excels. Bad design ignores the practical aspects in favour of aesthetic fripperies. In another life I was a qualified designer. When I did my job well, my clients loved the look and the use.
As for Teen76, get the faggots and stake ready - we'll burn the heretic
