Courgette plants way behind this year

There's been talk recently of the early spring and early summer bringing on an early autumn. But my courgette plants are way behind.

 

The (smaller) courgette on the right was one of 6 seeds I sowed in doors in pots on 6 May - the only one that properly germinated. The courgette on the left is one of 4 seeds I started off on damp kitchen towel on 5 June, transferring them to pots and then the 3 which grew being put outside last weekend.

In 2008 I picked my first courgette on 25 June - I doubt I'll get my first this year by 25 July!
