If your vine is not producing pumpkins there may be a problem with pollination. Go to You Tube and search "how to hand pollinate pumpkins". They will give you a better description of the process than I can. Apparently its pretty easy. Cheers Pete

You would have had to noticed if the bees went onto the pumpkin flowers or not. I recently had bees working on some flowers and not the zucchinis 2m away.

Every year I plant pumpkin seeds with no success. But late in the season self planted seeds grow and I’m lucky to get one pumpkin before the frosts come. What am I doing wrong..

The biggest mistake with pumpkin, beans, peas, corn etc is they are over watered and rot in the soil at planting time. Too much water and high temps cause them to rot. Temperate zone planting is Sept - Dec. To plant in Sept to mid Oct probably requires to have them in a warm place or indoors to germinate. Try and use a light soil/potting mix/seed raising soil. Or even a combo of these with some perlite. You want the soil to drain freely. Prepare your pots or garden soil and give a good watering, then plant the seeds, don't water again until day 4-5 and only lightly. Or another way is to place some paper towel on a plate, put your seeds on the paper, cover with another piece of paper towel. Give this a good watering and drain off the excess water. Re wet it morning and night draining off the excess water. When the seeds have sent out a tap root plant them into your moist soil.

My pumpkins 2 Queensland blue have grown to about 6inches across, but now are starting to die. Lost a lot of smaller ones, about 2 to 3 inches big. Doing all the right things I think. The butternut have no problems.

pumpkin trick is to deep plant the pumpkin from the start .dig a 1 foot plant in that, do not fill hole full of ground . let plant grow . when the plant is well above hole fill hole with soil .find the path u want the plant to grow and dont move . as the plant grows take out the runner branches .let grow for 3 to 4 meters then let 2 or 3 runners grow .when you have about 3 pumpkins nib any new runners ,keep pumpkin off soil use timber or tile .also as the plant grows the plant wants to grow up ,just put trowel on the growth ,this keeps it low to ground .why u grow 3 meters is because the leaves collect sun make plant strong for pumpkin to grow .also growing low to ground roots can appear at each branch that helps plant .i look at my plant at least once a week in growing time because u need to control its growth .i grew 3 big pumpkins for the first time and its worth all the attention .if u let it go wild the flowers just fall off or a pumpkin dies after a week or so and u end up with nothing

Go to a seed selling website like Boondie or Eden Seeds and look through the different types of pumpkin.
