Pumpkin Problems?

Hi Everyone, first post here

I'm trying to grow some Hundredweight pumpkins this year (preferably 1 giant one but will see how things go), but all I seem to have are loads of female flowers and no males :( I've had to prune the secondary runners and i'm worried i'll run out of females before the males flower:

Here are some pictures



Is there anything i can do or is it just a matter of waiting? They get watered every day (lots) and fed every week. They're in full sun (south facing garden) and with the heatwave we've been having have been growing really quickly? Theres 3 plants and all of them have long male stalks on but no flowers!!

Thanks

 

The same issue I have: plenty of flowers but none actually blooming. What have you been feeding them? I'm going to start on phosphorous soon. We have a giant pumpkin competition running on the forum also:

The more the merrier!

 

Just general purpose Tesco plant food, the soil isn't the best (about 20cm of compost on top of clay) as we only moved in in April and didn't have time to prepare the ground.

Is it worth getting a better feed for them? I've noticed the males are shaded by the leaves - do they need a bit of sun?

Hopefully with a bit of assistance I can grow something

Thanks

 

Sorry, it's potassium that I need to use now. Have been feeding them nitrogen incorrectly.

You'll find plenty of assistance here Smiley!

 

I feed mine with nitrogen feed to start to get allot of leaves growing then when you see an abundance of flowers switch to a phosphorus feed then when the flowers are pollinated I plan to switch to a potassium rich feed. the males on my plants have all grown on there stems to above the leaves when they have wanted to flower so I don't think them not getting sun is a problem. from what ive heard I think its probably just pure bad luck that all your females have come out first. nice garden btw.

 

Welcome to GC btw too. thought I was the only young un on here lol.

 

I've bought some blood fish and bone and watered a good amount in - fingers crossed
