Odd bits of rescued black plastic versus the weeds! Plus, I found a roll of clear polythene in the shed, left by a previous occupant, and have decided to see if I can warm the soil with it, to encourage the peas (and prevent access by pigeons). When the seedlings appear I'll raise it up somehow, cloche-style...

And yes, that's a plastic heron. There aren't going to be any fish in the pond, but I think herons eat frogs too, so they can stay away!
