Most crops have a preferred season or two to grow during. There are reasons for that. That is why this website recommends growing at certain times of the year.

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.

How long do I keep watering pumpkins? They are big now - mid Feb - leaves a bit mildewy. But new leaves growing.They were planted late Oct from memory.

I have been hunting for ages for the seeds of the Iron bark pumpkin, and so far have not been successful. Does anyone know where I can get them? They are a beautiful dry excellent roaster, and make great pumpkin wine! I also am growing something that lookes like a Jap, but has the shape of a butternut. They were self sown, too.
