I planted some butternut pumpkin seeds in January. They are only producing male flowers. How can I get some female flowers?

Give them some time. Quite often male flowers are first to appear, attract the bees.

in my garden now many pumpkins are sprouting, even if it is not the season. Maybe after eating pumpkins the dregs were dumped there. what shall i do? Do I remove them to save the space for other veges or leave them?

Howdy, If you can afford to give them that space e.g you dont need to use it for something else I say keep them in, might as well give it a go and see if you can get another harvest. I am currently growing Golden Nugget Pumpkins, they are a bush variety so can handle a bit lower temp/less light hours. One thing you will need to watch out for is powdery mildew as the plants tend to stay wetter for longer in the morning and the evening.

There is not much sense growing something out of season. You may produce a crop that has little or no produce. Grow some thing that is in season.

Google to find out some numbers. MAKE SURE you have plenty of bees in your area.

Different pumpkin types take different times to grow but most take over a month to fully ripen and you often wont see any finished products until mid or late March. It is definitely not time to give up yet. Good things to those who wait :) The plants will die very rapidly after the temperature drops in April and May. However if your getting mildew on the leaves in mid Feb I would recommend that you prune or spray the affected leaves to reduce the spread. I have had years where the plant died in late Feb before the pumpkins fully matured and I was very sad.

I have been growing Queensland Blues & Jap Pumpkins here in Sydneys West for a while and would like to know the following : Male flowers are plentiful usually at the start of the vine & female flowers are not as many but as the vine lengthens more females appear, so how far do you let the vine grow. If cut does the right ratio of flowers continue shoot or that stops everything, what you have is all you get and do you plug the cut end to prevent disease getting into the vine (read that on the net) Also everyone says when the vine withers pick your crop, mine was going great and green but I picked them (stem still green & firm) as I felt they were large enough but several had started to rot inside, we saved them luckey as another couple of weeks would have lost the lot. So how do you know when to pick. heard about tapping it sound hollow its ripe, pick a piece of skin with fingernail the skin can give you an idea. Noticed in the fruit shop many pumpkins have fingernail pieces dug out ??? somebody know something !!!!! As the pumpkin is pollinated & starts to grow do you sit it on a tile or similar keeping it off the ground ( for air & warmth circulation) sometimes when left on the ground the under side looks soft and worms and bugs seem to love that position.
