French Beans

I have tried the dwarf type of French Beans and had no success I am going to try the climbing ones in a big round tub I have ( 2' across 1'6" deep) I live in West Yorkshire and it is too cold to sow in situ so I am going to start them off in doors and plant out later in the month.  What type would be the best for this and how many to the tub (was thinking 4)  and any growing tips would be appreciated coz these are one of a fav veggies.

They like a bean-trench (dig down two spits, put in a spit of compost, shredded paper or manure, then fill in) for extra moisture.  In a pot, I'd add water-retaining granules or something.  They also need shelter from the wind (I reckon that's why I lost mine last year - the allotment site is more windswept than I realised!).

Stick the canes near the centre pointing outwards. Secure the top with an old bike rim. The plants can be sown near the edge of the tub and you may find room for five or six.
I agree with stripey_cat, you must have plenty of water storage in the soil. Expect to water these every day when the pods are developing. They are very thirsty.

Possible reason for the dwarf beans:- they need higher temp to germinate and they do not tolerate cold in any way.
