Thanks @Joyce Goldenlily (That's an enviably large bed!)Sorry what's GCs?I have two beds. One is 150x120cm and the other 120cmx120cm.I was watching Alan Titmarsh creating his 'small' kitchen garden on Ch5 last night, hoping for inspiration. I am taken with the idea of an arch over the gap between the beds to squeeze in extra things. Mind you he had about 5 ft between his beds. I have about 2!
