Broad beans plants but few pods

Its the chcolate spot that always does for mine, but did get a bagful in the freezer this year. Blackfly used to be a real problem but I found that if I just gritted my teeth and accepted that there would be some losses after about a week to ten days they'd all be gone - ladybirds and hoverflies I guess, although I did watch a blue tit scrape a load into its beak once!
Winter sown do better than spring in general.
