I have planted saved seeds from organic butternut and jap pumpkins and they are growing well...question is, one variety (not sure which) is spreading the way I know pumpkin vines to spread, and the other is growing in a bush shape similar to zucchini with little yellow balls (which I'm presuming to be pumpkins) clustered in the middle. They get to the size of a golf ball and then start to shrivel up...mmmm...mysterious. Appreciate any help. Thank you in advance!

From Adelaide here. Got butternut plant flowering lots now. But the ants are always on the flower. Do i have to rub the male flowers on to the females every day? Sometimes the petals on the females have already closed by later in the afternoon... is it alright to open the petals to pollinate them...?

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

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.

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 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.

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 plenty of Ironbark Pumpkin seed. They grow very well in Canberra. Also have "crosses' of Iron bark and Qld Blue which is afar superior pumpkin to both it's parents. Martha May give me a call on 62310508

To Tony, I tried your number because I would like to get some seeds of the cross between the Iron bark and Qld blue, can you let me know what your email or website is so I can order, thank you. Sue

I was hoping to plant some pumpkins, but I am worried they won't grow very well since it is almost the middle of July. Can I still plant some in my garden? I live in a very warm climate too.
