I first saw this on Malta. I had a go, quite successfully, on my allotment near Leamington Spa. I cut the leader to 5cm once the stem was about 10cm. They tillered well but variably; 2 to 5 new stems being produced. Needed much bigger spacing than normal (as on Malta, about 20 – 30 cm) and they were more susceptible to wind damage. They cropped about a week later than those untillered and were, again, very variable. Some new stems produced few pods but most were as prolific as the untillered. Certainly a good way to make bean seeds go further!
Hope the soil dries out in time for Spring
Cheers Will
