Runner Beans

The received wisdom from my generation [old] and older, is grow runners in an established made for purpose site year after year.  It has served me well.
Now I find that the advice is to rotate.
What is the experience of those who have followed the new advice after years of the traditional method please ?

Although I grow mine in the same place each year, I re-dig the trench, part-fill with compost and back-fill with soil from an adjacent area, which is more or less the equivalent of rotating anyway. 

we have our beans in a different patch every year at the lottie but the "old boys" don't seem to bother, they keep them in the same place each year, just easier I guess 

Is there anybody who has changed methods and can compare results ?

Runners are hungry and thirsty crops. If you use the same position remove some of the soil and replace itch plenty of muck. I have read that the roots can be over wintered in position for an early crop

They can! Several years ago I only had one dalek compost bin so chucked a load of veg waste on top of where I'd been growing my runner beans - having cleared the pile away in spring I was very surprised to see each old root sprouting multiple new shoots.

Unfortunately I needed the space for something else so dug them up, but I did subsequently try to overwinter tubers in the shed, but alas the frost and probably the damp did for them. 

Don't think they would survive winter in the ground in the UK without going to a lot of trouble - it's far easier to treat them as annuals as Sunny has suggested.
