I'm afraid my planting 'plan' is very random. Basically, as soon as I get a bed dug, I fill it with whatever needs to go out next! I decided it was better that than nowt, since I'm starting from scratch. A rational planting plan would have been nice in theory, but unachievable in practice! I'm still digging my way through the couch grass, yet.
I'll have to wait till the winter to dig up the concrete path which occupies the prime south-facing strip of garden, as I didn't have time to do that before the growing season this year. At which point, everything will swap round again. :)
