Courgette fruits mouldy and yellow

[Marb67]

Well for the life of me I don't know how my courgettes in the greenhouse, very healthy large plants have started to fruit and ALL are going soft, mouldy and some withering and yellow. The greenhouse is kept ventilated and plants not overwatered. The courgettes fruits that have gone mouldy are the round variety.

Are they still small fruits when they go bad? If so, it's almost certainly lack of pollination. Courgettes don't pollinate very reliably even outside, and in a greenhouse that problem is going to be even worse.
You'll need to hand pollinate. Pull off a male flower, strip the petals, then rub the pollen onto the stigma of a female flower.

Ok, will do thanks. Yes, when they are small this happens.

I had the same last year with Butternut squash in the greenhouse until I started hand pollination and I got a fair crop afterwards.
