I would advise against using shop bought pumpkin for seed. Most pumpkins grown commercially these days are hybrids that are bred to look like the well known varieties. They will not however produce true to type offspring. If you are happy to take pot luck then by all means go ahead and plant them, but if you really want a good tried and true pumpkin variety you will need to get seed from a seed supplier or a friend who has grown them before. Happy gardening one and all.

I planted my kent pumkins in September and have javested about 8 mature pumpkins...new pumkins are now starting on the same vine. Will they mature even though it is coming into winter?

Why are my home grown pumpkins watery? Not nice mashed.Would they make a nice soup.?

I have the same - maybe they might dry out if left for a month or so. Mine are jap - very sweet and moist. I probably pick them a bit early as I wanted to dig the garden up to plant other crops.

I am trying to grow pumpkin in raised beds without much luck. I have flowers that don't fruit. I have lots of bees in other beds but suspect there is a pollination issue. How do you tell the difference between female & male flowers, then how do I pollinate the female flower?

Ditto to Lisa above. The female flowers look like they already have a small pumpkin at their base. They are very easy to pollinate by hand.

The female flowers have what looks like a small pumpkin just behind the base of the petals the male ones have only got stalk there. The centre of the flowers are different too. The male flower has a longer, thin centre (think "male" and you get the idea) and the centre of the female flower is sort of a roundish swirl. To hand pollinate, remove a male flower and tear off the petals. The "male" part has the pollen. Rub it on the "female" part, the roundish swirl in the centre of the female flower. If it has worked, the pumpkin looking bit of the female flower will start to grow.

Hi, I have exactly the same issue. Is it worth self pollinating now that its nearly April and will the pumpkins grow?

How do you know when they are ready to harvest

Wait till the plant dies before harvesting.
