Courgette Rot

I've been lucky enough to pick one big healthy courgette so far, but on inspection today I found two of the smaller ones had gone yellow and developed rot around their ends.
Is there any way to prevent this happening? or is it merely down to the weather ( I'm considering buying some feathers and face paint to work on that one! )

 

Thanks John.
You might also be able to solve this one for me... one of my plants only seems to be producing male flowers, it's had about a dozen flowers all on straight stems, and no sign of anything that looks like it might develop into a courgette. Will it continue to do this ( in which case I might as well remove it ), or is there a chance that it will eventually produce fruit.

 

It'll pick up as the days get sunnier, had the same thing last year with male and femail flowers.

Try mulching around the plants, blossom end rot is weather related insomuch as to little and too much water affects the plants ability to absorb calcium, even if its on a chalky soil.

Mulching can help to regulate the soil moisture.

 

Probably too much water then Ziggy... I've got them in large planters.

 

Aah, make sure they can still drain ok, the mulch would still help, you won't have to water so much.

 

Hello Skinner.
As I see your courgette problems -
The male flowers always come first, but don't worry, the girls will be along.
If the fruits form but then just start to rot it's because the flowers haven't been fertilised. That's usually just down to bad weather and the bees can't do their job. But the plant will keep trying and come good when the weather is better.
Usually courgettes discard their own flowers, but if they don't fall off as the fruits swell then give them a gentle twist to take them off. That stops the courgettes rotting at the ends.
There is a self fertile variety - Parthenon - which does well in poor conditions, but I don't like it. I find something strange about the flavour and it smells funny - well to me anyway - like a dirty old mop.
In my experience courgettes always come good in the end. You'll end up with more than you ever wanted to eat. Good luck and start digging out the recipes.
