So this is the first time ive grown pumpkin or squash (as the americans call it) and im fairly familiar with how it grows. However im stumped with the way it is flowering, its a little over 10ft tall now, climbing my verandah and the first flower it formed when it was smaller was a single male which has still not opened, since then it has ONLY produced females with no more males in sight. it has around 8-12 female flowers several of which have opened but wilted as they will not be pollinated due to lack of males, i dont have any similar crops to cross it with either so i was wondering if there is any way to encourage the males? Thanks.
