My first attempt at growing courgettes ( in the greenhouse ) is going
badly wrong. There is a little bit of white mould on the leaves, though
nothing too serious, but every time a courgette gets going, the flower end
goes yellow, then brown and soft, then rot proceeds back towards the base,
the courgette eventually ending up as a soggy rotten blob covered in grey
mould. Is there an effective cure?

The 'cure' is to grow courgettes outside where the temperature is lower
and they will have plenty of space do develop.
