Well, I ended up doing far more than I'd planned this year - just couldn't resist.
I've been harvesting sweetcorn, cucumbers, lettuce, potatoes, spinach (what a great crop!) and herbs (basil and parsley), and I've got loads of butternut squash coming on nicely as well as some leeks looking good. I had a few drawf french beans from a couple of plants given to me by a plot neighbour. I think I'll grow more of those next year. And I'll try peas too.
So, mostly a success - just a couple of minor failures including spring onions (sparse and pathetic-looking) and bulb fennel (having no bulbs to speak of yet.)
Over winter, I'm planning to build a lean-to greenhouse against my shed, then chillis it is!
