Check with your neighbour next time. Next time wait until the stem has become hard and woody. About 16-20 weeks after seeds germinate.

I have 3 healthy pumpkins growing on the vine but the new baby ones are going yellow and dying. What causes this?

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 live in Te Anau and wonder what is a faster maturing pumpkin variety?? We had a good crop of pumpkins growing last year, but a rogue frost in mid March killed off the plant and the pumpkin crop did not ripen, and the weather is only coming good now (early Dec) to plant.

Look around some seed selling companies - email or phone them. Most times I see like 15-20 weeks to grow but which is early I don't know. Another way is to start the seeds early indoors or somewhere protected from the weather. You could start growing them in Oct say under lights. Sometimes nature throws us a big curve ball and stuffs it all up.

Great to hear of someone so young who wants to grow things. If this attempt fails, tell her to try next year. Plant around April/May and grow into the winter. If you have or can make a garden bed, tell her to try growing some radishes - nearly the easiest thing to grow. Go to Bunnings or a nursery and buy some punnets of lettuce or other things she likes and plant them. When starting out it is a lot easier to plant seedlings. The hard work has been done to germinate them. Also buy a little container of fertiliser (about 2kg or so) from nursery or Bunnings etc. I use a watering can (9 liters) and add a small tupperware cup of fertiliser to the water. Give it a good stir. Scale this down to say 1/2 to 3/4 of a tablespoon in 1-2 liters of water. Wait until the plants have grown to 3-4-5 inches. Little plants little fertiliser and more as they get bigger. Good luck.
