My pumpkin plant has pumpkins that are about the size of lemons. They are now starting to go a bit soft and mushy and don't look healthy. What is reason for that? Thanking you in advance

G'day Andy, I had the same problem mate. Dr Google says that the female is not being pollinated from the male. Apparently both male and female grow on the same vine and the bees do the pollinating. May need to plant some bee attracting flowers

Hi Andy, Your pumpkin babies may not have been pollinated. The female flowers produce the small pumpkin but unless it is pollinated from the male flower the pumpkin does not mature. I always find if I do it myself I don't lose any small pumpkins. I just look every morning and collect the pollen from the male flowers and wipe it carefully all the way around the female flowers, including inside the little "arches". You are meant to use a little brush but I often just use part of the pumpkin leaf, the pollen collects on it very well and always comes off in the female. Hope that helps. Jenny

I am growing Queensland blue pumpkin, I was told to feed the plant with potash. You can get this from a garden shop. It worked, so far I have had lots of flowers. Still to early to have fruit yet, here's hoping.

Last year 2014 I planted some Queensland blue Pumpkins at the end of the harvest I picked 22 pumpkins, but much to my dismay a lot of them were very woody why would this be can any one give me an answer as they weren't very good for pumpkin soup. Cheers Bazza

Hi Barry, as I understand it pumpkins can be woody if they've been cross-pollinated with other types of pumpkins. Do you have others planted nearby? Perhaps a neighbour does? Hope this helps, cheers, Ricki.
