Bean Frame Question.

As I'm sure you know runner beans climb by twining round their supports - the holes need to be of sufficient size not to make it too difficult for them to do that (but untangling the spent bines from the mesh in autumn could well be difficult!)

They'll happily climb at an angle (a la Munty frame) although the further away from vertical the supports are the more likely you are to have to "help" them from time to time.

The main advantages of a Munty frame are that unlike the traditional inverted "V" or wigwam the beans do not become congested near the top, and most of them hang down nice and straight and convenient for picking.

Although on the face of it it takes up more space than the single row you are proposing, you can grow other crops underneath the sloping area, and you will no doubt have to leave room on both sides of yours for picking the beans anyway.

You could probably build a Munty frame using your mesh instead of the more conventional stringing (or galvanised wire in my case) but I don't want to be accused of overselling something you might not be convinced about!
