I planted out said cucumber about five days ago. It's doing OK, though looking slightly frayed at the edges, from the cold nights!
I've been steadily planting out the runner beans a few at a time and have put the Borlotti beans in the earth too. So far, at least they are all untroubled by slugs and snails, or at least the barrier of plastic collars and bits of copper pipe around the plants is working. Elsewhere in the garden the same slugs and snails are on the rampage - even having a nibble at tomatoes, shallots and garlic, which they usually leave in peace.
