I’ve heard a mass of anecdotal evidence that this year was particularly bad for germinating French and runner beans. Even taking into account my usual method of getting enough seedlings for a crop, it was a struggle. My tried and tested procedure goes like this:
1. Sow beans in pots
2. A fortnight later, when they haven’t germinated and I am conscious that time is getting on, buy plants from local garden centre and plant out at allotment.
3. Check pots the next day to find seedlings have now germinated.
