Thank u Cindy and Keith. My pumpkins are about 2kgs in weight but turned from green stripes to yellow with tinges of green. They are solid and now have 9 on the vines but they are all going the same way. I have hand pollinated a couple but cannot understand why they are "yellowing". Am tempted to cut one open. your views appreciated!!!!

Pumpkin grew from compost that I put in the ground and have had four large pumpkins . I have given them plenty of water but they are all turning yellow. The stems are still green and they are hard with a "full" sound when tapped I believe they are Jap pumpkins and I`m wondering if this is natural to turn yellow. Would appreciate any response as I have never had pumpkins growing.

Sounds like it's a Butternut pumpkin. They grow from my worm compost too.

G'dday gary.....Im inclined to think your pumpkin did not get pollinated as it's only then they turn yellow, I would try hand pollinating next time to insure fruit set.. It's worth the try... Good luck Cheers ..keith

Ive had the very same problem with young pumpkin yellowing them falling off dur to lack of pollination,,, So I tried hand pollination but then the males didn't have any pollen showing on fingers or brush,,, I can only put it down to inmature males ??,,,, any answers to my problem would be most grateful

Had the same problem but found if i opened up the male flowers before they do it themselves , you get a hell of a lot more pollen that way.

I have pumpkin vines growing in my back garden which have gone berserk, can I cut back the vines without hindering the growth of the pumpkins developing.

Re Pumpkin's question : You can leave pumpkins in the ground until danger of frost is passed -- so it may still colour up, depending where you live ...

We have a huge green pumpkin that does not look at all like changing colour. Is it alright to pick and eat it. Your assistance would be much appreciated.

What is the best variety to plant in a small area? Is there a pumpkin that won't take over the entire yard?

Different pumpkin types take different times to grow but most take over a month to fully ripen and you often wont see any finished products until mid or late March. It is definitely not time to give up yet. Good things to those who wait :) The plants will die very rapidly after the temperature drops in April and May. However if your getting mildew on the leaves in mid Feb I would recommend that you prune or spray the affected leaves to reduce the spread. I have had years where the plant died in late Feb before the pumpkins fully matured and I was very sad.
