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.

My pumpkin's leaves are full of lice. What natural remedy can i use for that? Thanks

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.

How many plants must I plant in a hectare?

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.

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.
