It is weird that you are having so much trouble. Mine have plenty of
courgettes though the one overshaded by the spuds isn't as productive as
the other and I am making no special efforts to pollinate them at all.

Could be conditions or variety. My main ones are a different species,
and produce fruit that are good as courgettes up to several kilos.

It has been odd this year though. I grow them most years and I have
never known a year like it for a preponderance of female flowers. The
seeds are getting a bit elderly now so germination was a bit poor.

I think it was the excessively warm dry spring that did it. They were
very keen to set fruit ASAP perhaps as a result of the drought.

Last year the peculiarity was no apples here at all (but exotic nashi
pears were fine). I guess it was a badly timed frost or something.
