I have plants still growing from last year and producing new growth and flowers. Will these produce good fruit or should I tear them out and replant?

It's getting a little for pumpkins now in the UK though you never know your luck. A lot will depend on the variety. Hand pollinate as soon as you can to have the best chance of ripe fruit before frost.

I just moved into a house and the weeds had over grown after clearing out the garden I found a healthy butter nut pumkin vine however I accidently ripped up the roots when clearing it out I have reburried the roots but the vine is dieing how can save it?

If the roots were torn then it's probably a lost cause. You could try copious watering to try and save it, but it's late in the season now for pumpkins, anyway.

i grew my japs by just throwing the inside of pumpkins under some dirt. got heaps of pumpkins but not sure what to do after picking to ripen them.

Store the pumpkins for a few months in the shade and they should be ok to use for making chutney, jam, scones,bread etc.Mine seem to last for about 8 months after being picked.Any that get some withering,make some pumpkin soup.yum - yum!

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.
