I have Butternut pumpkins and pumpkins have started to grow. I won't know if they are not fertilized until they go mushy. Can I trim the vines and leave the best pumpkins to develop? Does it hurt to trim off leaves if a vine seems too leafy ? Jill

I'm new to this gardening business - at least, I've never had much luck before. Possums or bugs have eaten everything I've tried to grow, but 2016 is my year to succeed in the garden! I would like to plant some pumpkin seeds. Am I too late to do this now? Do I need to wait until after next winter to get seedlings going, or will I still be OK to plant some in January in Sydney? TIA

If you get them in now Katy you should have some success. I'd probably go for the butternut or the golden nuggets. Good luck.

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.

It is about 4 months too late by the guide here. It is not the temps now but what they will be in 4-5months time when the pumpkin are suppose to mature.
