The crisp texture and sweet taste of fresh peas embodies spring. Ancient peoples foraged for peas in the wild long before they were domesticated. Romans, however, believed fresh green peas were poisonous and had to be dried before they could be eaten. It wasn't until the time of King Louis XIV of France that a French gardener developed a green-pea hybrid known as petits pois. Fresh peas soon became the rage at the king's court and thereby quickly gained widespread popularity.

Types of Peas

Still a garden favorite, peas are one of the first vegetables that you'll plant and harvest in spring. There are extra-early, early, mid-season, and late types, taking 7 to 10 weeks to mature. Vining peas need trellises to grow on, while dwarf types need little or no support. Vining peas usually produce a heavier crop than do dwarfs.

Among green—or English—peas, there are wrinkled-seeded types and smooth-seeded types, both of which must be shelled. While wrinkled green peas are sweeter, smooth ones are hardier and better for super-early spring planting and for autumn and winter crops. If you've had problems with pea diseases, look for disease-resistant varieties such as 'Maestro'. If you want to can or freeze peas, choose a variety such as 'Dakota' that has a heavy and concentrated pod-setting period.

Snow peas and snap peas have edible pods. Snow peas produce flat pods that you can eat either raw or cooked. Snap peas are eaten either as young flat pods or after the peas have grown and are fat and juicy in the pods. Snow and snap peas are available in both vining and dwarf versions. New varieties of dwarf snow peas such as 'Snow Sweet' have pods that stay tender longer than traditional snow peas.

Some edible-podded cultivars have strings running down each pod that you must remove before eating; fortunately, "stringless" cultivars such as 'Sugar Spring' have been developed that eliminate this task. Edible-podded peas are perfect for stir-fries and other Asian dishes.

Field peas or cowpeas—which include black-eyed peas, crowder peas, and cream peas—are, botanically, beans. These plants thrive in areas with long, hot summers.

Planting Peas

Give early peas a sunny spot protected from high winds. Later crops may appreciate partial shade. You can also plant peas in mid to late summer for a fall crop. If possible, sow your fall crop in a spot where tall crops such as corn or pole beans will shade the young plants until the weather cools.

Early peas in particular like raised beds or a sandy loam soil that warms up quickly. Heavier soils, on the other hand, can provide cooler conditions for a late pea crop, but you'll need to loosen the ground before planting by working in some organic matter. Being legumes, peas supply their own nitrogen, so go easy on fertilizer. Too much nitrogen produces lush foliage but few peas.

Peas don't transplant well and are very hardy, so there's no reason to start them indoors. Pea plants can survive frosts but won't tolerate temperatures over 75°F. In fact, production slows down drastically at 70°F.

Southern gardeners often sow peas in mid to late fall so the seeds will lie dormant through winter and sprout as early as possible for spring harvest. On the West Coast and in Gulf states, you can grow peas as a winter crop. Elsewhere, if the spring growing season is relatively long and cool, plant your peas 4 to 6 weeks before the last frost, when the soil is at least 40°F. For a long harvest season, sow early, mid-season, and late cultivars at the same time, or make successive sowings of one kind at 10-day to 2-week intervals until the middle of May.

When planting peas in an area where legumes haven't grown before, it may help to treat seeds with an inoculant powder of bacteria, called Rhizobia. This treatment promotes the formation of root nodules, which contain beneficial bacteria that convert the nitrogen in the air into a form usable by plants. To use an inoculant, roll wet seeds in the powder immediately before planting.

Space seeds of bush, or dwarf, peas 1 inch apart in rows 2 feet apart. Bush peas are also good for growing in beds. Sow the seeds of early crops 2 inches deep in light soil or 1 inch deep in heavy soil; make later plantings an inch or two deeper. Thin to 2 to 3 inches apart. This close spacing will allow bush peas to entwine and prop each other up.

Plant vining types in double rows 6 to 8 inches apart on either side of 5- to 6-feet-tall supports made of wire or string, with 3 feet between each double row. The more simple the support, the easier it is to remove the vines at the end of the pea season and reuse it.

Generally speaking, 1 pound of seeds will plant a 100-foot row and should produce around 1 bushel of green peas or 2 bushels of edible pods. Another rough guideline is to raise 40 plants per person. Unused seed is good for 3 years.

To make good use of garden space, interplant peas with radishes, spinach, lettuce, or other early greens. Cucumbers and potatoes are good companion plants, but peas don't do well when planted near garlic or onions.

Growing Guidelines

Providing peas with just the right amount of water is a little tricky. They should never be so waterlogged that the seeds and plants rot, and too much water before the plants flower will reduce yields. On the other hand, don't let the soil dry out when peas are germinating or blooming or when the pods are swelling. Once the plants are up, they only need about ½ inch of water every week until they start to bloom; at that time, increase their water supply to 1 inch a week until the pods fill out.

Peas growing in good soil need no additional fertilizer. If your soil is not very fertile, you may want to side-dress with compost when the seedlings are about 6 inches tall.

The vines are delicate, so handle them as little as possible. Gently hand pull any weeds near the plants to keep from damaging the pea roots. To reduce weeds and conserve moisture, lay 2 inches of organic mulch once the weather and soil warms. This also helps to keep the roots cool. Soil that becomes too warm can result in peas not setting fruit or can prevent already-formed pods from filling out. Mulch fall crops as soon as they are planted, and add another layer of mulch when the seedlings are 1 to 2 inches tall.

Once a vine quits producing, cut it off at ground level, leaving the nitrogen-rich root nodules in the ground to aid the growth of a following crop, such as brassicas, carrots, beets, or beans. Add the vines to your compost pile, unless they show obvious signs of disease or pest problems.

Pea Problems

Aphids often attack developing vines.

Pea weevils can chew on foliage, especially along the edges of young leaves. They are serious only when they attack young seedlings. Apply Beauveria bassiana as soon as damage is spotted to head off problems.

Thrips—very tiny black or dark brown insects—often hide on the undersides of leaves in dry weather. They cause distorted leaves that eventually die; thrips also spread disease. Control them with an insecticidal soap spray.

Crop rotation is one of the best ways to prevent diseases. To avoid persistent problems, don't grow peas in the same spot more than once every 5 years.

Plant resistant cultivars to avoid Fusarium wilt, which turns plants yellow, then brown, and causes them to shrivel and die.

Root-rot fungi cause water-soaked areas or brown lesions to appear on lower stems and roots of pea plants. Cool, wet, poorly drained soil favors development of rots. To avoid root rot, start seeds indoors in peat pots and wait until the soil is frostless before setting out the plants. Provide good fertility and drainage for strong, rapid growth.

Warm weather brings on powdery mildew, which covers a plant with a downy, white fungal coating that sucks nutrients out of the leaves. Bicarbonate sprays can help to prevent mildew. Destroy seriously affected vines, or place them in sealed containers for disposal with household trash. Avoid powdery mildew by planting resistant cultivars.

Control mosaic virus, which yellows and stunts plants, by getting rid of the aphids that spread it.

Harvesting Peas

Pods are ready to pick about 3 weeks after a plant blossoms, but check frequently to avoid harvesting too late. You should harvest the peas daily to catch them at their prime and to encourage vines to keep producing. If allowed to become ripe and hard, peas lose much of their flavor. Also, their taste and texture are much better if you prepare and eat them immediately after harvesting; the sugar in peas turns to starch within a few hours after picking.

Pick shell and snap peas when they are plump and bright green. Snow-pea pods should be almost flat and barely showing their developing seeds. Cut the pods from the vines with scissors; pulling them off can uproot the vine or shock it into nonproduction.

Preserve any surplus as soon as possible by canning or, preferably, by freezing, which retains that fresh-from-the-garden flavor. To freeze peas, just shell and blanch for 1½ minutes, then cool, drain, pack, and freeze. Snow peas, which are frozen whole, are treated the same way, but don't forget to string them first if necessary. Peas have a freezer life of about 1 year.

If peas become overripe, shell them and spread them on a flat surface for 3 weeks or until completely dry. Store in airtight containers and use as you would any dried bean.
