the plants are still growing but the leaves are going a yellow colour, when we prepared the trench we put loads of horse manure in so it shouldn't be lack of food. any ideas?

I think they may be feeling the cold, did you harden them off before planting out.
You could try covering them with fleece to protect from the cold wind etc.

i thought that might be it, i did harden them off. on of the other allotment holder seems to think its because they need feeding but i dont think it is. i might just leave them and see what happens, i've got some more that should be up soon

[newbiegrower]

we had this with our runner beans but it was due to the fact of them needing a feed to help them so cant help much really

Probably the cold / windy conditions but perhaps NB has a point - would the roots have got down to the manure yet?

[lucywil]

so it might be worth feeding them anyway?

Only if you put the manure very deep.  Cold is more likely.
