1 part milk to 10 parts water sprayed on the effected leaves every couple of days might help.

We have had alot of rain for the past 2 weeks The vine is growing well and I have plenty of male flowers have grown pumpkins for years have not had this problem before cna some one help

Hi Trish, If all four of your pumpkins are on the same vine then you may be overloading the root system of the plant. I have found that two fruit on each vine gives good results. You could try adding more fertiliser in a circle around but away from the stem of the vine. Hope this helps,

how do you hand pollinate pumpkin

You need to take the pollen from the male flower and rub it onto the carpel (?) of the female flower. You can do this by either using a cotton bud to transfer the pollen, or simply just pluck a male flower from the vine, pull off the petals and then gently stick the flower stalk (with pollen on the end) into the female flower. Personally, I use cotton buds for my pumpkin and courgettes, but sometimes I will also use a plucked flower or just my finger.

My pumpkin is growing really well, about an inch or more a day, but the leaves closest to the roots have started to turn yellow, die and drop off. This yellowing and dying is slowly moving along the plant toward the tip. The new growth is still looking really healthy. What can be causing this yellowing? Could it be a lack on N or Fe?

No I haven't been able to get any more Windsor Black seeds I only had a couple of seeds that were given to me, I planted them on the side of a very small hill in Heavy soil they grew and branched every where were getting male flowers And the female flowers were forming, but 10 days of solid rain the patch was absolutely saturated the rest of our property was flooded I thought they would be alright but thr female buds went yellow & dropped off. I prayed & begged for the vines not to die but 90% did.I was shattered. one vine in the row above it The McLeay Mongrel survived Another Victorian Pumpkin, was so sick I just forgot it, went down the Hill the other day the grass was 2 & 1/2 feet high and I trod on something in the grass and nearly fell over looked and found one McLeay Mongrel Pumpkin I have collected the seed from what has to be the weirdest Pumpkin ever, But probably the nicest eating Pumpkin ever, I would say it is probably the rarest as well. The McLeay Mongrel Is a very dry pumpkin with superb flavor much like Iron Bark sweeter & nuttier, I have looked at it it is more than likely a Triamble Iron Bark cross Maybe some Qld. Blue. I am offering 4 seeds up for Auction on eBay I do not have many seeds, so thought if I put a good reserve in them only the very serious growers would buy them. Be Warned it is not a pretty pumpkin but needs some serious pumpkin growers to keep it from extinction, it is a heavy solid pumpkin, looks like an Alien lava Rock. visit eBay Pumpkins just to see it. Regards. Sylvia.
