I only grew two plants of sweetcorn last year (in the polytunnel) but they were a great success, so am going for a big block in the ptunnel this year. I will have to underplant otherwise I lose such a large space, so interested in the courgettes, but had thought about lettuce. Is this a good idea? Don't know why I thought of that, perhaps I read it somewhere.
Any other ideas for underplanting?
