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

I am growing a jap pumpkin . I have four good size pumpkins on but now all the female flowers are not opening they turn yellow and drop off. 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?

I am just south of Townsville and planted Qld Blue pumpkin seeds in early April in good soil with correct PH levels. Plenty of space to run and good sunshine and watered daily. The plants grew well for about 6 weeks producing masses of mostly male flowers?? I had plenty of bees doing their job, but still only got two pumpkins that didn't reach maturity before the plants died off about 2-3 weeks ago. We did have a couple of 6deg nights but nothing lower. Any advice would be very much appreciated. Cheers
