I'm growing grey pumpkins,do they grow bigger fruit if you cut end of runners off once plant has several pumpkins on it.

Do you want a few big ones or a lot of average to good size? My cues last year - if I had cut - would have picked 18 - left to grow 49 cues.

Don't cut unless limited by space.

Google it - organic or in-organic.

Organic or inorganic spray that is.

This year my pumpkins are quite robust, a good yield due to creating a beehive I reckon. But its very hot here in NE Victoria, the plants are struggling, despite 2 daily waterings and although the stems haven't dried off my instincts tell me to pick them before they get affected as well. Am I right or wrong?

If the stems haven't dried off fruit will be immature and tasteless. They will not keep .Leave on the ground. Risk of rotting is slight and worth the risk. If you are unduly concerned you could always lift the fruit off the ground onto a piece of wood or similar. I rarely lift mine until May / June. Graham (berwick Vic)

I grow pumpkins every season. If you want your pumpkins to grow big you must make sure the entire plant gets watered and fertilised regularly as the vine sends down a root at about 1/2m intervals in search of water and food. When you start getting female flowers (with a pumpkin attached) you need to fertilise them by getting pollen from the male flower, just put your finger inside and you will see the pollen on it, gently brush it on to the middle of the female, once pollinated the new pumpkin will go into a growing frenzy, (I know they are about 90% water ) Water, water, water! And food, My best Kentia/ Jap went 12.2 kg 33cm high, save the seeds and keep them in the freezer. Veggies are the best.
