Pumpkins form with flowers still attached and then the pumpkin rots. I am now removing the healthy flower before the pumpkin starts to rot to see if that will allow the pumkin to grow properly. They are the kent variety of pumpkins. Has any one have any tips to share.

Pumpkin seeds should be planted in spring / early summer, but I have just planted my seeds and they are doing great, bit late but I'll see how they go....

Ben I believe that if you place some of the leaves of the vine over the pumpkin this shades the fruit and less likely to split. In the hot Canberra summer I have had great success with part-shade for growing the pumpkins. A friend advised that overfertilizing during the growth phase is not good either. Better to have the soil fertilized at the planting stage rather than topping up in between. She may have a point.

re Marlen Traynor - pumkins like a clay or heavy loam and not really a sandy soil. Add some clay by getting a few bags of brickie's loam that brickjlayers add to their "mud"or china clay as used by potters or animal feed manufacturers to your soil. Can't cause any harm.
