At the allotment I planted out the sweetcorn, runner beans and purple climbing french beans grown in loo roll tubes at home, plus sowed some dwarf french beans in between the sweetcorn. This worked really well last year as the beans shade out weeds and also fix nitrogen in the soil for the corn. Well, it worked ok until there was a population explosion of teeny snails which decided they really enjoyed eating bean leaves anyway. THis year we've cleared a lot more of the plot so hopefully we won't have as much of a slug/snail problem
Anyhoo here's some pics of the seedlings (click for a bigger view)
Tomatoes overseeing the little teeny basil on the top row plus lots of brussels and cabbages on the middle.
