Once again my courgettes are not reaching maturity!
They get to the size of a large cigar and the end rots off. Any suggestions
please?

It has been very wet so blossom end rot (and slug damage) has been a
problem this year. Small courgettes are very tender and excellent stir
fried with a hint of chilli and pasta.

They are in a greenhouse if that makes any difference

Mine are outside and cropping reasonably well now.
