I just planted pumpkin in 10 spots with 2 seeds at each spot. Only 2 spots had 2 plants germination. Sometimes it is for germination reasons. I basically had the same result from apple cucumbers.

Or transplant one of the pumpkin to another spot and grow it also. When planting 2-3 seeds close together think about planting them 100-150mm apart so that if you want to move them then you can retain a fair amount of soil around the roots when moving them, helps with transplant shock.

I lived in Papua New guinea the climate is usually wet and dry season all year. Can I grow butternut pumpkin in that kind of climate?

Can a Butternut Pumpkin be grown from a top only, and what would be the best method? I'd love to try it if there's a chance it may work. Thank you kindly.

I don't see it working. Stick some skewers in it and hang it in water.

I have grown my first pumpkins this year, and they hung on the vine. Amazing, 3.8kg hanging! Now, my question is: if I store them outside, will the possum eat them? Thank you in advance

Possums ate mine - so did the rats! So you need to store them where these sharp-toothed creatures cannot reach them.

For Robert B of Sydney West,17 April, dette-19April andMichael Stapleton 4 May. Forget about growing Jap Pumpkins. They are rubbish, far too soft to make good roasting pumpkin.. About growing pumpkins - plant your seed in September/October, male flowers will appear then in second week January the females will start. If fruit does not develop and turns yellow and dies that means the female has not been pollinated by the male, due to absence of bees. You will have to do it by hand. Determine how many fruit you want and then remove any female flowers that appear. I usually leave this until March. Do NOT prune the end of your vine. Feed with potash and phosphorous (liquid manure the best organic source). Note - phosphorous helps initiate the onset of female flowers The first pumpkins will be ready to pick in mid April. Place some coarse straw under the vine in January where you find a female (to prevent rot). Happy to answer any questions and provide seed of "Ironbark", the original Aussie pumpkin and still the best for colour, flavour and texture (sweet, smooth and dry - lovely) Tony 02 62310508
