I'm growing grey pumpkins,do they grow bigger fruit if you cut end of runners off once plant has several pumpkins on it.

Do you want a few big ones or a lot of average to good size? My cues last year - if I had cut - would have picked 18 - left to grow 49 cues.

Don't cut unless limited by space.

I have 3 healthy pumpkins growing on the vine but the new baby ones are going yellow and dying. What causes this?
22 Jan 19, Liz (New Zealand - temperate climate)
They are going yellow and dying because they have not been pollinated. Try using a soft small paint brush, or something similar, to transfer some pollen from a 'male' flower (one without a tiny pumpkin behind it) to a 'female' flower - one with a tiny pumkin behind it.

Thanks for that, I assumed that if a pumpkin formed it must have been pollinated.

The female flowers are only open for 1 day and usually closed by lunch. Have to be on the ball to pollinate them.

Or break off a male flower and peel back the flower part, then rub the female flower with the male part. Make sure the male has pollen on it by testing with your finger. Even do this with 2-3 male flowers.

I have grown pumpkins 2 years in a row that have hard white lumps in them, I have bought a plant both times so I am thinking it must be something to do with were they are growing. Any idea of what could be coursing this?
