Peas are a cool-season crop that can be grown either as bush or vining plants. Referring
to your seed packet or catalog for detailed instructions regarding germination, 
support needs, and days until maturity, will help ensure success in cultivating 
them successfully.

Peas are legumes and can fix nitrogen through nodules on their roots, though if 
your soil is poor you may wish to add an inoculant (powdered bacteria).

## Soil Preparation

Peas are an annual spring vegetable that require cool temperatures and light frost
protection until flowering occurs, then they need warm weather protection until 
blooming takes place. When exposed to direct sunlight or in warm temperatures they
become susceptible to disease and pest problems including aphids, powdery mildew,
pea weevils, nematodes and caterpillars which require cultural practices in order
to be prevented.

Inoculating pea seeds with nitrogen-fixing bacteria known as rhizobia is one of 
the key steps you can take to maximize your crop. Rhizobia naturally exist in soil,
yet only become active once they come in contact with legume roots and form nodules
along their roots – trading nitrogen for sugar produced by plants. When inoculated
into seed, these nodules immediately activate, starting their work of fixing nitrogen
for your crop as soon as it leaves its pod.

To properly inoculate your pea seeds, soak them for one or two days in a solution
containing equal parts water and vermiculite for quicker and more effective conversion
of nitrogen from air into plants by the rhizobia bacteria. This allows more efficient
conversion from nitrogen in the atmosphere into plant nutrients.

Once inoculating, the planting site should be prepared as described above. Peas 
thrive best in deep, rich soil in full sun. They don’t tolerate sandy, light or 
sandy-loamy soils well. Furthermore, it must have a pH between 5.8 to 7.0 as peas
are sensitive to high levels of acidity which interfere with their relationship 
between rhizobia and legume roots symbiosis; pH test kits are readily available 
at most garden centers to determine the current state of pH; should you need adjustments,
lime or sulfur can be added as necessary to bring it within acceptable parameters.

Once your planting site is prepared, plant your peas as soon as the ground has thawed
and become workable. For tall vineing varieties of peas, sow the seeds at the base
of a trellis or other support structure so as to prevent their pods from rotting
on the ground and make harvesting them easier. As they grow larger, regularly remove
non-flowering branches to allow your plant to focus its energy on producing pods
instead.

## Planting

Garden peas flourish best in cool temperatures and can tolerate frost, while they’re
vulnerable to hotter temperatures. Spring planting provides optimal conditions, 
though fall planting can still produce results; just expect less reliable yield 
due to shorter days.

Pea plants require support when they start to mature. A sturdy trellis should be
constructed out of thick wire or twine panels and installed near where they will
grow in your garden. Peas will quickly grab onto whatever support is provided to
them and climb, so it is imperative that its strength can withstand their weight
as they make their climb to maturity.

Vining varieties of peas can grow to reach 8 feet tall on what are known as indeterminate
vines, producing beans continuously over an extended period. Conversely, short bush
varieties flower and set pods at once, making harvesting possible within three weeks
or less.

Your pea harvest should be sweet, tender and thin-skinned if harvested at maturity;
over-matured peas become starchy and lose their sweetness.

To avoid picking too often, closely monitor pea plants and sample some pods daily
near harvest time. Once the pods have become swollen and round, it’s time to pick.

Once the peas are planted in your garden, it’s advisable to cover them with 50% 
shade cloth or two layers of floating row cover until they have at least six leaves–
this protects them from sunburn and pests such as flea beetles, vegetable weevils,
leafminers, slugs and snails. When watering, use either a soaker hose or drip irrigation
so the soil remains moist without becoming waterlogged; don’t overwater as that 
could lead to fungal diseases; water early so foliage has time to dry before nightfall
falls!

## Harvesting

As soon as your peas are ready for harvesting, they should be collected. Regular
harvests ensure that the plant keeps producing pods; to do this effectively it’s
recommended to start at the bottom and work your way upwards as the pods mature 
and become ready. Remember to enjoy fresh peas as their sweetness and taste are 
enhanced when eaten right away; for freezing purposes harvest prior to any signs
of wilt developing in them.

Young pea plants can survive some frost, while flowering varieties should be protected
from late frosts to protect flowers and the developing pods from being damaged by
frost. Frost can damage flowers as well as cause deformed seed pods. If your region
experiences frosty springs, make sure that you protect your peas by covering the
garden with a row cover to shield your garden from further frost damage.

Trellises can be great options for growing tall varieties of peas. As their tendrils
spread across their supports such as bamboo and netting, wood frame trellis covered
with chicken wire or metal fencing and even fence posts, peas grow prolifically 
over time. You could also try dwarf or bush varieties which won’t require as much
support over time – these produce fruits over an extended period of time without
needing one at all!

Peas are nitrogen-fixing legumes, meaning they can use airborne nitrogen to “pull”
their own fertilizer from the atmosphere to improve soil. However, for sandy or 
unfertilized soils it may be wiser to add additional nitrogen fertilizer after planting
peas in order to facilitate their growth and boost your yield. When selecting liquid
or powder forms of nitrogen fertilizer products it’s important to follow label directions
to maximize yield potential.

As peas near maturity, it is advisable to remove any non-flowering stems beneath
their flowers in order to focus energy into producing pods. It may also be beneficial
to enclose them with twine as they start climbing the trellis; you can do this by
tying twine above each plant, placing it down near each one, like ladder rungs –
and continuing to tie small loops as the peas climb higher up the trellis.

## Storage

Peas are an ideal cool-season crop, flourishing best when the temperatures remain
mild. At planting time they thrive most vigorously while tolerating frosts or light
snowfall in spring. Sown as soon as the ground can be worked in early spring for
harvest in late August/September for fall harvesting.

Garden peas require well-draining soil amended with coarse sand and compost for 
optimal growth. They don’t need much in terms of nitrogen fertilizer; however, starter
or side dressing in poor soil may help them get established more quickly. As with
other legumes, pea plants are natural nitrogen fixers which increase soil fertility
with each harvest cycle; to further boost this process if your soil lacks richness
you could consider inoculating with Rhizobium bacteria which encourage this vital
microbiome’s presence inoculating it will promote their presence!

If you plan to grow an abundance of peas, raised beds or beds with an ample layer
of mulch may be your best bet for keeping weeds at bay while conserving moisture
for the plants. Peas can quickly rot in moist soil; by keeping moisture at a stable
level you’ll extend their lives significantly.

As with most crops, pea growing directions will be included on their seed packet
or catalog. Different cultivars of peas have specific needs that must be fulfilled
to grow successfully; read carefully as guidelines vary based on spacing requirements,
support needs, days until harvest and other important details.

Pea pods may be harvested either during their snap/green or shelling stages for 
fresh eating varieties that are sweet, tender and have thin skins. Picked when crisp
and bright green, before their seeds swell. Overmatured peas lose their sweetness
and become tough and starchy;

Once your peas have become ready to dry, they will begin turning brown and the seeds
rattling inside. Take them off their plant and hang them upside down in a cool and
dry location to finish drying before storing in paper bags or similar containers
for later use. Keeping peas fresh for several years in an ideal storage location.
