If the broad beans are not staked, and consequently fall over due to heavy rain or strong winds, they will not be able to reach their full potential. As soon as they blow over, the broad beans start to mature instead of continuing to feed the pods.
It is worth tying broad beans to a stake if they are growing on fertile soil, as they grow tall and tend to blow over in heavy rain or wind.
LodgedBroadBeans
When the broadbean plant blows over it ‘lodges’ with other broad bean plants and stays close to the soil. Some of the leaves will be hidden from bright light so the broad bean pods will not be fed so well which means that they will not grow and fill with good sized broad beans.

The beans in the picture lodged at a late stage in their growing period, so will provide a decent harvest. But if the lodging had happened at flowering time, the broad bean pods would not have filled properly.

It is well worth taking the time to stake broad beans.
There are two schools of thought on how to freeze broad beans – some people blanch the beans before freezing and some don’t.
Blanching involves plunging the beans into boiling water to stop all enzyme activity with the beans, so the beans stay exactly as they are without any deterioration. Therefore, the healthy vitamins and minerals will remain in the beans. After a couple of minutes at boiling point, the beans are dropped into ice-cold water, to stop the cooking process.
Podding-Medes-BroadBeans
To freeze broad beans by blanching:
shell the beans
plunge the broad beans into a very fast boiling saucepan, so the water just covers the beans
return the water to the boil as quickly as possible
after 3 mins,drain the broad beans
immediately put into ice cold water to bring temperature down quickly
Why are some mature broad bean pods empty, with immature, undeveloped beans?
Broad beans need the right day-length and a temperature of about 20°C at flowering. If the beans are planted too early in the spring, & there is a blip in the weather as the first beans flowered, the beans will not set well.
Crops planted too late will also produce low yields and will be affected by high temperatures later in the season.
Broad beans produce less well in windy areas. Double rows (20 cm apart) help the plants to withstand wind. Otherwise a windbreak pays dividends.
ExpressBroadBeanPods
Broad bean pods tend to be empty at the start of the season, before the conditions are right for the beans to set.
Gardeners often pinch out the tops of broad beans to curb black fly. We very rarely pinch out the tops. But if blackfly are a problem, the tips may be pinched out when the first pods are set.
To pinch out the tops:
* first select the top of the broad bean plant

* find broad bean top

* Hold the tip between finger and thumb

* pinch the tip so that it breaks away from the plant
Chocolate Spot on Broad Beans (Latin name – Botrytis cinerea and Botrytis fabae)
Chocolate spot is a fungal disease which attacks Broad Beans in the
vegetable garden.The leaves and stems, when affected, are covered with
dark brown lesions, which look as though they have been covered in
chocolate powder.
*Causes of chocolate spot*:
* overcrouding – dense crop with lush growth
* high humidity – wet season
* acidic growing conditions
* too much nitrogen fertiliser
* winter sown crops more susceptible
*To avoid chocolate spot*:
* give plants plenty of space
* do not apply nitrogen fertiliser
* burn affected plants after harvest
*Effects of Chocolate Spot on Broad Beans*
* beans are still edible, although the pods are discoloured
* reduced yield as pods do not fill
* death of plants if severe
A mild attack of Chocolate Spot on broad beans in the vegetable garden
is not a disaster. A satisfactory crop of beans may be harvested. It
is a warning to give broad beans a healthy start next year with plenty
of space for air to be able to circulate round them.
Every vegetable gardener has to decide when broad beans are ready to harvest.
A lot depends on how the individual likes to eat them – small, sweet & tender, or large with flavour!
broad-bean-pods-filling
If the pods have swollen and the beans inside are properly formed, but still really small and sweet, the whole pod can be cooked and eaten with the beans inside.

It is always a balance between yield and sweet tenderness. (more…)
