I asked someone for advice about growing broad beans, as I knew he used to be a farmer and he still grows his own vegetables in someone else's garden. It turns out that he used to grow broad beans by the million for canning by Smedleys.
He has very kindly given me advice about which ones to grow, followed up with a gift of a bag of Aquadulce Claudia broad beans, which can be sown now.
The winter will make them dormant, or whatever the horticultural term is, and then they get going again as soon as the weather warms up. I had to look on the internet as to how to sow them, because I did not know which way up to plant them.

Yes, they are planted on their side. This weekend, I will be planting some of them.
He also explained that marigolds are a good companion plant for carrots, as the marigolds deter carrot fly.
