I produce only a few pumkins because of limited space. But I usually
help the bees, when the pumkin extends to the limits I set, I snip the
shoots and I find opposite sex flowers will then start to develope.

I suspect that this might be somewhere that we are failing. We tend to
just let the blighters grow, but I have noticed that female flowers only
form late and only a few at the ends. So I am determined next year to
snip early to encourage branching of the plants, rather than a couple of
long runners.
