I have been scrolling through pumpkin comments. I am not sure if this will help, but make sure your hands are very clean when pollinating. Also, I have a query- pumpkins growing well, but on some, main stalks have been broken off accidently. Have put these under shelter where sun gets them-when are they ripe? do they sound hollow, or are they supposed to sound full?

I have orange pumpkins growing. The fruit is still mostly green, but the plants are pale and dry - more or less dead it seems. Should i harvest now, or wait until they are more orange?

You should leave pumpkins until the stalk is completely dry and hard, then they keep without rotting.

I have a mildew problem on my pumpkins. started on rockmelons which didn't survive, and has passed on to my pumpkins. I have tried milk watered down and sprayed, and camomile tea spray but nothing seems to kill it. want to avoid using chemicals as i have a relatively organic garden

Hi there, Problems with mildews: What type is it ?? Is it Downy Mildew or Powdery Mildew? Downy has white spores growing under the leaf and Powdery has Greyish spores on top of the leaf. The rule of thumb is Downy uses Copper based sprays and Powdery uses Sulfur based sprays. Both of these chemicals are naturally occurring elements and are not harmful to people or environment. There are other sprays out there that can be used in between these sprays and should be encouraged as mildews can become resistant if you spray the same chemicals continuously. Hope this helps. Stoo...

We have the same problem here in Brisbane, after hand pollinating the fruit goes yellow and dies off.

Living in Brisbane planted in November, plenty of male and female flowers have found after hand pollinating female flowers with small fruit that is turns yellow and dies. Has anyone know what the problem might be.

I have a jap pumpkin growing, my problem is that there is only male flowers growing on the vine, when the female flowers grow they die of, can anyone tell why this is happening, do I need to pull it out and start again?

I had the same problem. I picked the male flower and poked it in the female flower to pollinate it. It worked I ended up with lovely big pumpkins.

Hi Dawn, Unfortunately April is not the right time to grow pumpkins in Victoria as we are heading into winter. Pumpkins require a fairly long growing period of 4-6 months (depending on the variety) of warm weather and are they are very frost sensitive, so will die once winter hits. If you are keen to grow something now, cabbages, broccoli, Asian greens, lettuces, radishes and carrots are pretty good bets. If you have your heart set on growing pumpkin, best to wait till October/November for sowing/planting for best results. Cheers & happy gardening.
