Planted my Suttons direct in ground early October. Earthed them up with a ridge and covered them with enviromesh to deter the mice etc that dig up the beans, and doing fine now, will uncover shortly as they are about 6 inches high now. I used to grow in pots in cold greenhouse, and plant out in November (uncovered), but found the stalks quite 'leggy' and prone to snapping off, so have planted direct on recommendation from other plot holders on my allotment. Seems to be working they look a lot stronger now.
Always do Autumn sown beans - usually Aquadulce, have planted two closely sown rows of each this time, to aid support, and to see the difference between the two varieties. I believe the Sutton is a smaller plant, so may be less prone to winds, which has happened to me in the past.
