I've done many things over the years in my broad bean plots.
Will be in mid July, when they are finished for picking here.
Always put a later crop of Brussels Sprouts in, to add to the one doing nicely in the plot now. Have some started their growth nicely in the greenhouse now for planting out then. Especially as they are late, leaving them to be picking early next year or even just for those lovely Brussels Sprouts tops.
Plenty of your extra Chard plants or even a new sowing now does well.
Do also tend to use the area for quick succession salad crops like lettuce, radish
