Great tip from Yarralumla Nursery: I've had trouble getting my pumpkin fruit to set. I get small fruit up to 10cm that then wither and die. I've corrected acid, I've hand pollinated, I've water regularly and fertilized heavily, all to no avail. Someone at the nursery asked if the plant was large, healthy and still producing shoots - yes it was. They suggested clipping the ends of each tendril/shoot to stop it growing so the plant can concentrate on growing fruit, not leaves. It seemed to work - the next few flowers to polinate have progressed to a mature pumpkin.

I have planted 3 butternut pumpkin plants and they have all grown rambling vines about 3m long. Each has flowered and started to produce fruit but the now the leaves closest to where the plant comes out of the ground have all dried, died and fallen off the vines. This has left me with about 1m of dry woody stem and then 2m of plant with lush green leaves and small healthy looking fruit. This is the first time I've planted pumpkin so I don't know if this is normal behaviour for these plants or whether there is a problem with them. Any advice greatly appreciated.

Hello, in early december 2009 i noticed a few pumpkin plants starting to appear in my chicken cage. i started watering them as soon as i noticed them growing. it took about 1 and a half months to take off and produce flowers. but the flowers kept falling of the stems and still are, what do i do to stop the falling off??. the plants are now covering about 25 to 30 square metres and climbing up the fences and on the roof. i have about 8 pumpkins on the plants, 3 which are quite large. because they grew with out my intensions i am unaware what varietys they are.. i am willing to send pictures to anyone who could please help me identify them!.. im almost certain that 1 of the few plants is a butternut... Help Me Please.... Ben

Hi, I'm new to this. I am growing butternut pumpkins. They have spread everywhere and are getting beautiful yellow flowers but no pumpkins. What am I meant to be doing? I have had success with my snowpeas, corn and carrots...just not pumpkin. Can someone please help?

Hi have had great sucess planting a pumpkin in straight compost. It has loved it and one plant has given me four decent size pumpkins with some smaller ones growing. Have trailed it up on some plastic lattace over a water tank which has worked a treat!

Gina, We too have been wondering when to harvest a Pumpkin "buttercup" as is looks large, green & with yellow in a couple of places (like its picture). We cut it and then read that the stalk needs to turn brown before harvesting. So we have taken it too early it seems. Haven't cut it open yet to see it its got any yellow flesh. We will now leave the others that are growing till stalk is brown.
