Your plants aren't very old yet. give them time to produce some male and then female flowers. Hand pollinate if you have no bees. Read back a page or tow of comments here - a lot of info. Your big leaves maybe from too much nitrogen/very rich soil. Pumpkin take about 16 -20 weeks before picking.

The female flower is there for a few days - if it is not pollinated then it will rot and fall off. If you put water into the flower it will probably rot. The flower is only open for one morning so hand pollinate it if you don't have any bees. There is a shortage of bees world wide. It might be a bug/disease and I have no idea. Have the plants out in the open and not in shade damp areas. Water low and in the late afternoon - no water into the female flower.

Is it true that the growing butternut must not get direct sunlight? It must be covered?

I have lots of pumpkin flowers but only one pumpkin has formed. A friend mentioned male and female flowers. Can/should I remove flowers that aren't going to produce fruit?

If you go to the Australian - sub-tropical zone - there is quite a bit about this with pumpkin. Pumpkin produce male flowers first then they have female flowers, The female flower is only open for one day (until about mid day). No bees no pumpkin. So hand pollination is required. Take about two male flowers and rub the female flowers with it. Look up the internet on how to do it. This applies to zucchini, cues and melons also I believe.

My Pumpkins are the same. Still growing like crazy and flowering. I thought they are supposed to be finished? This is my first time growing them down here (Victoria). I guess we'll just have to leave them until the plants die off.
