... how tidy should I keep my garden ...
The important word here is should.
A gardening philosopher (Mara Grey) once said that the worst disease in any garden, worse than any slug, or virus, is 'guilt' - the feeling that the gardener must do this or must do that.
It's your garden and you can do whatever you like, providing that it doesn't upset the neighbours too much.
Tidiness is not compatible with wildlife. Nature would like you to leave things alone. Obsessive tidiness can be a symptom of OCD - obsessive compulsive disorder - it's a form of mental illness. The desire to regiment and control plants in the garden may extend to the desire to control other people.
Chill out, man.
