Too late/early to sow broad bean?

That's what I did last year - start them off in pots in the greenhouse or cold frame

Never grown these before so what size pots should they be grown in?, and when would be the right time to plant them out?

1 seed per 3" pot in a good compost. Larger pots will be fine.
They take about 4 - 6 weeks (depends on temperature) before hardening off, any longer and they become pot bound with the tap root growing out of the bottom of the pot.
They need to be hardened off well before planting out sometime in March when the ground / weather is suitable.

The chart suggests leave it until February now but if you have enough seeds to experiment, why not try some now and leave most until next month?

My diary says I sowed mine the first week of Feb 

Bear in mind you might still get mice in your greenhouse though 

Mine are sown in 3 ins pots in the just frost fee greenhouse (aquadulce) and I hope for 100% germination.

Sowed them on 2nd Janaury.

Later than this would be fine of course, up to about April outside tbh

Sorry for hijacking the thread..  perhaps this may help...

No problem. I do it regularly. Cheers for the link.

Thanks for all the replies folks. I think I'll pot a third of them up (I have 35 seeds) netted against mice).

Hi, I'm from South Devon. Aquadulce are a variety of broad bean that can be planted in the autumn. They will grow on until the cold weather of winter and go into a dormancy period above ground. They can survive a degree or two of frost. I lost all mine during the severe winter last year. They can still be sown now. I also recommend starting off in pots at home. My friend lost all his bean seeds to burrowing mice a couple of weeks ago. Don't let the plants become too tall before planting out.
