I have been growing Queensland Blues & Jap Pumpkins here in Sydneys West for a while and would like to know the following : Male flowers are plentiful usually at the start of the vine & female flowers are not as many but as the vine lengthens more females appear, so how far do you let the vine grow. If cut does the right ratio of flowers continue shoot or that stops everything, what you have is all you get and do you plug the cut end to prevent disease getting into the vine (read that on the net) Also everyone says when the vine withers pick your crop, mine was going great and green but I picked them (stem still green & firm) as I felt they were large enough but several had started to rot inside, we saved them luckey as another couple of weeks would have lost the lot. So how do you know when to pick. heard about tapping it sound hollow its ripe, pick a piece of skin with fingernail the skin can give you an idea. Noticed in the fruit shop many pumpkins have fingernail pieces dug out ??? somebody know something !!!!! As the pumpkin is pollinated & starts to grow do you sit it on a tile or similar keeping it off the ground ( for air & warmth circulation) sometimes when left on the ground the under side looks soft and worms and bugs seem to love that position.

I am looking for "Spookie" Pumpkin seeds. Can you help me please? I understand the Spookie is a smallish, hard skinned, long keeping flavoursome pumpkin, that WILL grow well in South Queensland (Gold Coast) ?? Any advice would be valued, Thank you, Evelyn

Just wondering if anyone has some advice, I have some butternut pumpkins which have been growing really well, but now the leaves have started to die in the middle, am I going to loose my pumpkins which are nearly ready to pick??

I have been looking for the Ironbark Pumpkin too. I would appreciate Ray Selby pointing me to who has the seeds I would like to buy them as I don't have any seeds to swap yet as we recently moved from the tropics to Canberra and I have just made 3 large above ground beds. Not sure what pumpkins do any good here but happy to give them a try, come September?Oct. I have other pumpkins lined up to see what survives here. But would like the Ironbarks as they are a delicious pumpkin for all cooking. If you can help thanks.

We have hundreds of Ironbark Pumpkins and sell them at the markets in Beenleigh, Brisbane...if that is any help Elle. Alternately we can organise seeds for you.

I have been hunting for ages for the seeds of the Iron bark pumpkin, and so far have not been successful. Does anyone know where I can get them? They are a beautiful dry excellent roaster, and make great pumpkin wine! I also am growing something that lookes like a Jap, but has the shape of a butternut. They were self sown, too.

Ferolyn: I pick the male flowers first thing in the morning, peel the petals off then rub the female flowers (pumpkins, luffa, zucchini etc)

Just found this - commercial production. For efficient pollination and fruit set, there must be: both male and female flowers and bees to move pollen from male to female flowers. A number of factors can influence pollination, Cold and overcast days limit pollination activity of bees. Hot dry conditions desiccate pollen making it unviable. Rapid growth promotes earlier flowering. However, high temperatures, long days and high rates of nitrogen can result in: vigorous vegetative growth and few flowers and a higher proportion of male to female flowers. It is important to check the sex of the flowers. A ratio of 1 female to 7 male flowers is usually considered adequate. Flowers open early in the day and for one day only, and they close by mid afternoon. These periods are shorter under high temperatures. Flowers are most receptive to pollination in the morning when bee activity is usually the highest. Bees are necessary for pollination and must be active in the crop. Flowers require at least 12 bee visits for good pollination. If bees are not plentiful, introduce at least two hives per ha after female flowers appear and male flowers start producing pollen. Spread hives around the field outside the crop, preferably so that bees have to fly over the crop to get to another food source. Destroy flowering weeds around the crop.
