As you can see, they've been producing some great courgettes but not quite as many as last year. Realise I shouldn't have put two courgette plants per pot. The plants aren't as big as normal (they can be gigantic if you give them ample space, e.g. in a veggie plot) because they're competing for nutrients and space, so the result: less courgettes.
Seeing as it's just the two of us that's ok but next year I'm going to dedicate one of my veggie plots to courgettes because I want an ambudance to try out numeous recipes with. The year I grew them in the ground, they produced 3-4 a week atleast! That year I made pretty much every courgette recipe going in the Sarah Raven Garden Cookbook (my favourite recipe book).
