I need some help from you wizards please - my courgettes are starting to rot before they are big enough to harvest. I'm assuming this is because of the wonderful summer weather we are having.

Two different varieties (yellow is Parador F1, green is Nano Verde)
Is there anyting that can be done? These aren't just fruits that are sitting in contact with the ground, they are above ground level.
- you could cloche them but then you'd have to hand pollinate......

Everything else seems fine which is a relief!
