Peas - Pisum sativum
Peas are definitely one of our essential crops. They are easy
to grow, easy to cook – or eat raw, healthy, easy to freeze or dry.
Sowing
and Growing –
Peas prefer a well cultivated plot in a sunny and unexposed
site on well drained and fertile soil. Of course, for many of us, this is not
an option but, my heavy clay soil on a fairly exposed site can also produce
excellent crops of peas.
Although I know of growers who plant their peas and beans on
the same site every year as the correct conditions have been set up for them, I
do think it is advisable to rotate these crops. I like to follow my potato
crops with beans and peas as the ground has already been well manured in the
previous season for potatoes.
I used to follow instructions in vegetable growing books for
planting peas [dig a trench 2in deep or 5cm. and space the peas 3in apart or 8cm
along the trench] or something similar. I always wondered why I always had such
a miserable spindly crop. I spoke to an elderly neighbour on my allotment who had
been growing for years and had amazing lush and productive pea crops. He laughed
and then demonstrated to me how to sow peas – dig a trench 2-3 in [5 – 7cm
deep] sow a whole packet of seeds or more – my trenches are 4 -5 metres long –
sow 1 – 2 packets of seed along this trench by sprinkling fairly extravagantly
along the trench. I usually sow about 3 trenches with 4 – 5 packets of seed. The
plants are then fairly self supporting although I do stake them with 1 metre
canes fairly liberally – on a diagonal in each direction, providing a
criss-cross network of support. I sow the rows fairly close together 2 - 2½ft [60
– 80cm]. Although this spacing does not allow me to weed easily when the plants
are maturing, the dense pea cover also blocks out most weeds. Of course you can
use branches of shrubs or trees as stakes or you can spend a lot of money in
setting up staked and wired supports. Unless you are a perfectionist gardener
this is not really necessary – for me the crop is the end product, not the
tidiness of my plot – though, of course, this is also important.
Slugs, snails and pigeons are a particular pest on my
allotment when the peas are emerging so I use slug pellets and put nets over my
plantings.
Mice and perhaps rats or birds can also dig to access the
chitting seeds. I’m not sure how to prevent this though netting can, obviously
help. Birds have a way, in spite of our best efforts, of finding their way
under our netting which can make them ‘sitting ducks’ for hungry predators like
foxes. Do make sure the trapped birds have an easy escape route in case of
panic – that said, I haven’t always been successful in this endeavour.
Although peas and beans have, for a long time, been thought of
as a good source of nitrogen, the nodules on their roots fixing nitrogen in the
soil, recent research has shown that this is not the case. It is now believed
that this is not the case – that the ‘fixed’ nitrogen is only available to the
plant that produces it.
Types and
Varieties –
Peas can be classified as:
- Earlies which take 11 to 12 weeks to harvesting time
and can be sown as early as late February to early March under cover or cloches
[depending on the weather and your situation]. They can then be harvested as
early as May – June. Or they can be sown outdoors from late March to mid April
for harvesting June/July.
Try - Early Onward, Kelvedon Wonder, Little Marvel, Twinkle,
Meteor
- 2nd Earlies which can take between 12 – 13
weeks to harvesting. Sow outdoors when the soil has warmed up a bit, from mid
Spring. Try - Early Onward, Kelvedon Wonder, Little Marvel, Jaguar, Avola,
Hurst Green Shaft [called ‘ the grower’s favourite’ with some justification].
- Maincrop will take 13 to 14 weeks to harvesting time.
Sow from mid April to mid May. These are likely to be the peas which will
provide a heavy crop for freezing for winter use. Although there are other
varieties, my favourite, by far, is Hurst Green Shaft – they are heavy
cropping, sweet, good to eat raw, excellent for cooking and for freezing. Try
also, Oasis, Bingo [good for pots in the back garden or patio, Rhondo,
Starlight.
- Late Maincrop – It is still possible to sow
peas in July for autumn cropping into September, although the crops are not
likely to be so heavy and there is more risk of maggots in the pods and peas and
mildew from later sowings. Although it is a risky crop, if you have the space
and the weather is kind, it is a treat to eat fresh peas late in the season.
Try – Starlight, Rhondo, Kelvedon Wonder, Ambassador, Douce
Provence [which can be sown as an overwintering variety or from early Spring under
cover].
Peas can also be classified as:
-Shelling peas – are grown to maturity and
taken out of the pods to eat – the pods are not suitable for eating. The varieties
listed above are all ‘shelling peas’.
- Mangetout – a literal translation from
French means ‘eat all’. At the immature stage the peas are harvested and eaten
raw or cooked in their pods. They can also be grown to maturity and harvested
as Shelling Peas.
Try – Sugar Ann, Kennedy, Sugar Flash, Shiraz [a purple podded
variety], Oregon Sugar Pod, Delikata.
- Sugar Snap – very sweet, small peas. They
are ususlly eaten as shelling peas but can, when immature be eaten as Mangetout
- try Cascadia, Oregon Sugar Pod.
- Asparagus Peas - psophocarpus tetragonolobus – are not really peas but, are a member
of the vetch family. I have grown this vegetable once – well you have to
experiment with different vegetables! While some growers think highly of this
vegetable and it is, undeniably very pretty, it is something of a nuisance to
harvest. The winged pods must be harvested very regularly or they become tough
and uneatable. The pods are tiny [2 – 3 cm long] and hard to see for
harvesting. It takes a lot of them to provide a vegetable dish. I tried various
ways of cooking to make a tasty dish but, failed – I found them fairly
tasteless.
Harvesting
and Storing
Freezing – A wonderful vegetable for freezing – sit
out in the garden on a warm sunny day and pod them. Do check for mould or
maggots and discard any damaged or under-developed peas. Pack them into
suitable freezer bags, seal and freeze. Don’t forget that, when you come to use
them, the peas are uncooked, they do need a few minutes to cook, unlike bought
frozen peas
Drying – Only attempt to dry peas from undamaged
and undiseased pods and discard any which look undeveloped or underdeveloped, The
given advice is to allow on them to dry on the vines or, bring the dried pods
home and allow them to dry out completely before removing from the pods, or use
a dehydrator if possible. As I am often harvesting in damp conditions, I am
more inclined to harvest when the pods looks as though they are drying out [not
always dry on the wet ground!] bring them home and pod. I discard any discoloured
or damaged pods or peas, being a bit worried about pests – especially bean and
pea weevil. I lay the seeds out on tray in a coolish room with good
ventilation. When the peas are well dried – this may take a couple of weeks -
they should be very hard and give a sharp sound when dropped on the tray or
surface- they should then be dry. Peas are a good subject for seed saving for
the following year though, it is a good idea to buy in new seeds every few
years to avoid a disease build-up.
Nutritional
Value
Peas are low in fat and sodium [salt] and contain no cholesterol.
They are high in fibre and protein [though an incomplete protein]. They are
good source of Vitamin A, Vitamin B – riboflavin, niacin. B6 and folate. Also
Vitamin C [when fresh- 1 cup provides 98% of daily needs] and Vitamin K.
Good source of minerals – phosphorus, copper[trace element],
manganese
Pests and
Diseases
Pigeons – will eat the young growth from any young
plants on our plots when nothing else is available. You might find that you
need to net these crops if this appears to be a
problem. Pigeon damage has increased hugely in the last 10 years – many
plot holders claim this is a direct result of the decline of the number of
birds of prey on our fields as a result of some people laying poisoned bait for
these wonderful raptors. If netting, do leave an escape hole for those intrepid
birds which do find a way in.
Slugs and Snails – these can be a serious problem
when the bean plants have just emerged or are very young and tender. In a damp
year, they can clear your bean patch overnight.
Bean/pea Weevil will attack young plants and may
destroy a young crop if serious but, more mature plants should outgrow any
attack.
Seed Beetle or Weevil – if you are storing beans for
seed or for eating the dried beans during the winter months this may be a
problem. Seed will need to be checked regularly [weekly] when small round holes
will be apparent or the small beetles in stored jars. Sort and remove contaminated
seeds and the beetles or destroy the stored vegetables if the infestation is
serious. [ see above].
Aphids – can be a pest but is not common – keep an
eye on ant nests near your plantings and spray with SB plant invigorator [
organic and feeds the crops as well as reducing the numbers of pests and
diseases.
Mildew and Botrytis – Many varieties these days are
resistant to these diseases though attacks of aphids can leave the plants open
to infection, especially in wet years. Spray with SB plant Invigorator an
organic compound which will encourage the plant to outgrow problems.
