🌱✗ Tested and false“Broad beans are a spring-sown crop, like most beans”
A hardy variety such as Aquadulce Claudia can be sown in October or November and left to overwinter, cropping from May, well ahead of a spring-sown batch.
Our read Most beans genuinely are spring-only, frost-tender crops, so it's a reasonable assumption that doesn't happen to hold here: broad beans are hardier than the rest of the bean family.
What to do: Sow a hardy variety in autumn for an early May crop, alongside your usual spring sowings for a longer summer supply.

“Pull up the whole broad bean plant, roots and all, once harvesting is finished”
Cutting the plant down at the end of harvest and leaving the nitrogen-fixing roots in the ground lets them release nitrogen back into the soil for whatever's planted next.
Our read Pulling everything out feels like the tidy, thorough thing to do, but on a nitrogen-fixing legume it throws away the crop's main soil benefit right at the point it would actually pay off.
What to do: Cut plants at the base once cropping is finished, compost or dig in the top growth, and leave the roots in the ground.

“Pinching out the growing tips is just about keeping the plant a tidy shape”
RHS and Gardener's World both give pinching out shoot tips as a specific defence against blackfly, done once the first flowers set, not as general tidying.
Our read It looks like the same light pruning gardeners do on lots of crops for shape, but the timing and the reason here are both precise: it's pest control with a deadline, not aesthetics.
What to do: Pinch out the growing tips as soon as the first flowers have set pods, specifically to reduce blackfly, not whenever the plant looks untidy.

“All broad bean varieties need staking, the same as tall types”
Dwarf varieties such as The Sutton, at around 45cm, suit windy sites and containers, and grown in double rows they often support each other without staking.
Our read Most of the named varieties are tall enough to need proper staking, so it's easy to assume the whole crop does, but the dwarf types exist specifically to avoid that step.
What to do: Stake the taller varieties with canes and string as they grow. For an exposed or windy site, choose a dwarf variety instead and skip staking altogether.

“Blackfly infestations are just bad luck, nothing predicts a bad year”
Warm springs are the specific condition that makes black aphids worse, which gives a real, if partial, reason some years are worse than others.
Our read It's easy to write off a pest as random when you can't see the mechanism, but this one has a named weather trigger, even if it's not something you can control.
What to do: Pinch out shoot tips as soon as the first flowers set pods regardless of the year, but expect the risk to be genuinely higher after a warm spring than a cool one.
