GM, that sounds like a brilliant idea, just wish I had enough space. Yes, which compact courgette please.
For the first time ever some of my climbing beans are weak, and failing, right from the start. Never saw that before. Some are ok in a different spot. One year I put a couple of Scarlet Runners to climb through a crab apple. It was really pretty and quite productive.
How disappointing for you I'd have loved to see a picture of that - pretty and accessible.
