Slow growing peas

My peas have got to be about 8-10cm tall and seemed to have stopped growing, and my runners bean plants look quite yellow rather than bright green (like on the next plot over) - what am I doing wrong? Any ideas?
Thanks x

There is something radically wrong this year nothing seems to be germinating or growing right.
and what dose grow the slugs and pigeons eat

My fruit bushes are looking fantastic (at least the ones I pruned properly last year).  Peas, beans and beetroot all very sad - but just started to perk up a little. I have for the first time had to use slug pellets.  Also, I've just resown rows of beans and peas hoping for a late crop where there were no-shows.

One crab apple tree that is 3 years old has gone really sad looking - brown leaves and really thin foliage. 

Yes, pop some round all the plants - they'll love it!
