Beans
and Peas are legumes, that is, they are members of the Leguminosae
plant family. These plants are able to make use of atmospheric nitrogen
as a food. They can therefore grow in soils that lack the nitrogenous
salts which most plants need.
The area where you have grown your beans and peas can be planted
the next year with vegetables from the brassica family, such as
cabbages, broccoli, kale, etc. If it is possible for you to arrange
your growing area in 4 sections, you can plant each group of vegetables
in a different bit of ground each year for 4 years. Well designed
crop rotation is the key to good organic practice. It helps with
the control build-up of pests and diseases, and with the maintenance
of soil health and structure. Your production of vegetables will
be sustainable over the long term. Please see also our webpage called
OTHER NOTES.
Crop Rotation
Where
Beans and Peas fit into a 4-year rotation – a basic plan :-

Broad
Beans (Vicia faba) have been grown since ancient times.
They are extremely nutritious beans. They are high in protein and
are an ideal meat substitute. The expression “feeling full
of beans” refers to these beans. The plants are grown for
the shelled out immature bean seeds. They are hardier than “French”
or Runner beans, and can be autumn or early spring-sown. They grow
to approximately 1m tall, and the flowers are usually white with
black markings. They can also be grown as a “green manure”
(a crop grown to improve the soil structure and fertility), cut
down and turned over into the soil before the pods form. Gardeners
and farmers who use organic methods of growing appreciate the nitrogen
enhancement that these plants give the soil. This will greatly benefit
the following crop. All legumes give this benefit – so by
growing beans and peas you will be improving your soil at the same
time as providing your own food.
“French”
or kidney beans (Phaseolus vulgaris) are of native
american origin, and were introduced into the UK in 1597. More varieties,
with their evolved characteristics, were taken to the US and Canada
by immigrants from Europe, and, in some cases, have since been lost
to their country of origin. We are sourcing them, bringing them
back, trialling them, and then offering these wonderful original
varieties for you to grow for yourselves. “French” beans
are mainly grown for their tender green pods. There are also purple
podded varieties, and also yellow pods which tend to crop earlier.
Runner Beans (Phaseolus coccineus) are of
south or central american origin, and although known by UK gardeners
since the 16th century, the Runner bean was grown exclusively for
its scarlet flowers as an ornamental climbing garden plant until
the early 19th century. “Dutch runners” are white seeded
and white flowered. Runner Beans can be eaten at the green pod stage,
left for the seeds to swell and eaten at this stage in the manner
of a shelled out Broad Bean, or left to go dry and harvested at
the end of the season. These seeds will the be useful for winter
use as “butter beans”. They need to be soaked overnight
to take up water, and simmered until tender.
Peas
( Pisum sativum)
Peas leave a fertile soil too. Many can be eaten fresh green, usually
the smaller the more tender. Others are delicious dried, rehydrated
and used in winter soups, etc. Some varieties are particularly good
when eaten at the whole pod stage (called mangetout or sugar snap).
Such is the food value of peas that our helpers have found that
just two pods of peas opened and eaten raw have sustained them for
an extra half hour of manual labour ! |
