Pollinating the cucumber flowers while the plants are locked in the greenhouse, away from insects, turned out to be a non-issue.  The plants we chose are self pollinating.  That’s pure luck – no forethought involved at all.  It’s now possible to see the baby cucumbers growing on the vine.  The yellow flowers are a beautiful colour too.

In the foreground, is a tiny cucumber – I think it is called a Mini Muncher. In the background, the self-pollinating flowers.
