Topic: Why are pattypan rotting?

[antipodes]

I grew a green pattypan squash this year, and the plant has been most vigourous, huge even. However I noticed that there is not that much fruit in proportion to the plant's size, and many of the small fruit that I picked (I love them small, about 8 cm across) has quickly rotted from the flower end (like, in 24h!!).  What is going on there ?  Is it a pollination problem ?   They were grown in a patch with cukes and butternuts. Thanks for any ideas!

I grew these just once n Belgium and found their relatively thin skinned meant they rotted off easily and they were slow to develop any depth of flavour.  Are your sitting on the ground or raised up to get the sun?   That might help and would avoid any snail or slug damage that may start the rotting process.

I shall be going out in the next day or so to cut off all the foliage beyond viable fruits on all my pumpkin plants to stop the plant trying to grow on and set more fruits.  I want them to concentrate their energies on teh existing fruits.  Might help with your patties too.

STill surprised. They grow in a bush so they are off the ground, although there is a lot of foliage. The skin is about the same as a courgette but they don't rot like that.  They don't seem damaged when I pick them....

Sorry then.  No idea unless it's linked to the drought and inadequate/fluctuating moisture levels.  65mm here since mid Jan.

Didn't know the answer but remembered that Google is our friend(?)

Looks like it could be ph too low, needs some calcium (lime)

That is very good to know AF.  Thanks.  Our soil is mildly acid so now I know to add calcium next year for squashes as well as brassicas

Interesting article. Yes I think our soil is a little acidic, must put some lime in perhaps. I had blossom end rot on the tomatoes too, as rain has been sporadic. I didn't link the two but looks like it is related.
