How To Grow Peas: Requirements For Growing Peas

Peas are spring’s reward for making it through yet another winter. The plants produce sweet, crisp pods and tender peas early in the gardening season. Native to the Mediterranean region and western Asia, peas have been grown for thousands of years and are a favorite in home gardens because they produce a bounteous crop, are easy to grow, and are delicious both fresh off the vine or cooked.

Peas thrive in cool weather and grow best in full sun with fertile, well-drained soil. They prefer temperatures between 55-70°F (13-21°C) and can tolerate light frosts, making them ideal for spring and fall gardens. Depending on the variety, peas can be grown in USDA Zones 2-11 as an annual crop. Most gardeners find peas to be a beginner-friendly crop, especially when grown with a simple trellis or support for climbing varieties.

The variety and gifts of peas is seemingly endless for anyone starting a vegetable garden. In addition to producing nutritious pods and edible tendrils that are rich in fiber and vitamins, pea plants also improve soil by fixing nitrogen, benefiting nearby crops in the garden.

Quick Pea Facts

What is a Pea?

A pea is the edible seed of the plant Pisum sativum, a member of the legume family (Fabaceae). When you eat peas—whether they’re inside a pod, flat like snow peas, or plump, small emerald-green balls like garden peas—you’re eating the plant’s seeds before they fully mature and dry.

Botanically, peas are legumes. This means the plant forms pods after flowering, inside of which are the developing seeds (peas). If those seeds were left to fully mature and dry on the vine, they would become dried peas used for split pea soup or stored seed for another planting.

What makes peas especially interesting in the garden is their relationship with soil. Like beans, pea plants host beneficial bacteria on their roots which then can convert atmospheric nitrogen into a form plants can use. This helps naturally enrich the soil.

The pea plant has a bonus gift for the kitchen, too. Its shoots are edible! Pea shoots are usually harvested from snow or sugar snap pea varieties. They are harvested as young 2 to 6 in. (5-15 cm.) shoots and include two to four leaf pairs and the immature tendrils. They may also include small flower buds. Pea shoots have a subtle pea flavor and a light and crunchy texture.Use them fresh in salads or in stir fries.

Types of Peas

Peas come in three main types—garden peas, snap peas, and snow peas—and each offers a slightly different eating experience, harvest style, and role in the kitchen.

Garden peas, also called shelling peas, are the classic type of pea most people think of. Their pods are tough and inedible, so the peas must be removed (or shelled) before eating. These are harvested when the seeds inside are plump and sweet. They are commonly used fresh, cooked in dishes like soups and side dishes, or frozen for later use. Some varieties of garden peas include:

• ‘Little Marvel’
• ‘Lincoln’
• ‘Wando’
• ‘Thomas Laxton’

Snap peas, also called sugar peas or sugar snap peas, are a cross between garden and snow peas in texture. Their pods are rounded, crisp, and fully edible. You eat the whole pod while it is still tender and sweet. Snap peas are popular in salads, stir-fries, and as a fresh snack. Examples includes:

• ‘Sugar Ann’
• ‘Sugar Daddy’
• Dwarf Gray Sugar’
• ‘Sugar Bon’

Snow peas are harvested very young before the seeds inside fully develop. Their pods are flat, tender, and also entirely edible. They are widely used in Asian cooking, especially stir fries, when their delicate crunch and mild flavor stand out. Some of the more popular varieties are:

• ‘Oregon Sugar Pod”
• ‘Snowbird’
• ‘Snowflake’
• ‘Avalanche’

While snow peas and snap peas may sound similar as they both have an edible pod, there are significant differences between the two that help gardeners decide which variety to grow. Explore the different types of pea seeds available—even ones with purple pods!—at Burpee Seeds.

Planting Peas

As one of the earliest crops in the garden, peas are rewarding in the number of pods that can be plucked off the vines up until the weather becomes too warm for their liking. Their performance depends on timing, placement and season-long care.

When to Plant Peas

Peas are a cool-season crop, which means timing is everything for a successful harvest. They grow best when temperatures are mild, typically between 55–70°F (13–21°C), and they will definitely struggle once heat sets in. Because of this, peas are usually planted very early in spring as soon as the soil can be worked—often 4–6 weeks before the last expected frost date. In many regions, this means planting can begin as early as late winter in warmer climates or early spring in colder ones.

Gardeners in USDA Zones 2–11 can grow peas as an annual, but the planting window is relatively short everywhere. In cooler zones, peas are primarily a spring crop. In milder climates, they can also be planted again in late summer for a fall harvest, as long as there is enough time before freezing temperatures arrive. Peas are a legitimate crop in places with very mild winters.

Peas germinate well in cool soil, so there is no need to wait for the soil to warm. In fact, hot weather will quickly reduce flowering and pod production, making timing critical. For the best results, plan to harvest your peas before daytime temperatures consistently exceed the mid-70s°F (around 24°C). Plant a few pea seeds every couple of weeks during the early season to extend your harvest window.

Best Soil for Peas

Peas grow best in fertile, well-drained soil that is rich in organic matter. A loose, crumbly texture helps young roots grow through the soil easily and supports strong early growth. Ideally, soil should have a slightly acidic to neutral pH, around 6.0–7.0. Add a bit of compost to the soil before planting to improve both fertility and moisture retention.

Peas do not like waterlogged soils, so ensure that your soil permits good drainage. At the same time, the soil should hold enough moisture to keep roots consistently damp during germination and flowering. Because peas produce their own nitrogen in the soil through nitrogen fixation, you won’t need to add much if any additional nitrogen. Too much nitrogen may lead to lush foliage but fewer pods.

Light Requirements

Peas grow best in full sun, meaning they need at least 6–8 hours of direct sunlight each day for strong growth and good pod production. In cooler climates, full sun helps plants develop quickly and produce a higher yield before warm weather arrives.

In regions where spring temperatures rise quickly, a bit of light afternoon shade can help extend the harvest by preventing heat stress. While peas can tolerate partial shade, too little light will lead to weaker vines, reduced flowering, and fewer pods.

How to Plant Peas Step by Step

• Choose the right time: Plant peas as soon as the soil can be worked in early spring, about 4–6 weeks before your last frost date.
• Prepare the soil: Loosen soil to about 6–8 inches (15–20 cm) and mix in compost to improve fertility and drainage.
• Inoculate seeds (optional): Coat seeds with a soil inoculant, which you can find at a garden shop. This helps to boost the nitrogen-fixing process and improve plant growth. The Micronoc Seed Inoculant available at Amazon is a blend of nitrogen-fixing bacteria, phosphate solubilizers and beneficial fungi that help create a thriving soil ecosystem to get you peas producing efficiently.
• Sow seeds: Plant seeds 1–2 in. (2.5–5 cm) deep and 1–2 in. (2.5–5 cm) apart in rows spaced 18–24 in. (45–60 cm) apart.
• Water gently: Keep soil consistently moist but not soggy to support germination.
• Provide support: Install a trellis or pea fence at planting time or soon after to help support climbing.
• Mulch: Add light mulch to conserve moisture and suppress weeds as plants grow.

Pea Care

Peas are a crop that is often squeezed into that brief time between workable soil and the heat of summer. That means a keen eye on their growth and care is in order for the best crop possible.  

Watering

Be sure to keep your eye on the moisture of the soil your peas are planted in. Peas need consistent, even moisture to grow well from germination through pod development. Keep the soil moist but never waterlogged, because excess water can lead to root rot and poor growth. Aim for about 1 inch (2.5 cm) of water per week, adjusting for rainfall and temperature. Deep, infrequent watering is better than light, frequent sprinkling, as it encourages stronger root systems. Once plants begin to flower, steady moisture is especially important to ensure full, tender pods and to prevent flowers from dropping prematurely. Using an irrigation system such as the Rain Bird Landscape and Garden Watering Kit available at Home Depot can help you provide the steady moisture your peas need for peak performance.

Fertilizing

Peas are light feeders and generally don’t need heavy fertilization. That’s because they can they can fix their own nitrogen thanks to beneficial bacteria in their roots. In fact, too much nitrogen can lead to lush leafy growth with fewer pods. The best approach is to enrich the soil before planting with compost or well-rotted organic matter to provide balanced nutrients. If additional feeding is needed, apply a low-nitrogen, balanced fertilizer, such as Espoma’s Flower Tone, a 3-4-5 formulation available at Lowe’s, sparingly at planting time or when plants begin to flower. Avoid high-nitrogen fertilizers, and instead focus on supporting healthy soil biology for the best pea production.

Mulching

Mulching peas helps conserve moisture, suppress weeds, and keep soil temperatures more stable as cool early spring morphs into warm late spring. A light layer of organic mulch—such as straw or shredded leaves—reduces water evaporation and helps maintain the consistently moist soil peas prefer, especially during flowering and pod development.

It also limits weed competition, which is important because peas don’t compete well with aggressive weeds. Apply mulch once seedlings are a few inches tall, being sure to keep it slightly away from the base of the stems to prevent rot.

Pruning

Generally, peas do not require pruning. They naturally focus energy on flowering and pod production, not necessarily branching and leave production, so most growth management is unnecessary. However, you can remove any yellowing or damaged leaves to improve airflow and reduce disease risk.

If plants become very dense, light thinning can help improve light penetration and airflow. Some gardeners also pinch off the growing tips once vines reach the top of their support, but this is optional and mainly helps with managing plant size rather than increasing yield.

Supporting Peas

Your pea plants will most likely need supporting because most pea varieties are natural climbers that use tendrils to grab onto nearby structures as they grow. Without support, these vines will sprawl on the ground, making pea pods harder to find and more likely to rot or be damaged. A simple trellis, fence, netting, or even rows of sticks or branches is all it takes to guide growth upward.

Install supports for your peas at planting time or very soon after germination so young vines can attach early and grow upwards. The type of support depends on the variety—shorter peas may only need light staking, while taller vining types can require structures 4–6 ft. (1.2–1.8 m) high or more. Materials like bamboo canes, chicken wire, or even string mesh all work well, as long as they are sturdy and allow tendrils to wrap easily. A structure such as the FlexGrow A-Frame Trellis from Vego Garden can be expanded and arranged in multiple shapes, and can work with containers and well as in raised and garden beds.

When you provide good supports, you’re not only improving airflow and plant health but also making your future harvesting easier.

Harvesting

Your best pea harvest depends on two factors: timing and frequency. And those factors depend on the type of peas you planted.

Snow peas: when pods are flat and tender

Snap peas: when pods are plump but still crisp

Garden or shelling peas: When pods have filled out but before the seeds become starchy or hard.

Once flowering begins, check your plants daily because peas mature quickly, going from perfect to overripe very quickly. Harvest in the morning when pods are crispest and sweetest. When picking the pods off the plant, use two hands—one to steady the vine and the other to gently remove pods—to avoid damaging the plant, which could reduce future yields.

Regular harvesting from the plants will encourage them to continue producing pods and will extend your overall harvest window. Once peas become overmature, they lose sweetness and plants will eventually stop producing as temperatures rise.

Interested in harvesting pea shoots for something a little different to add to salads? About six to eight weeks after sowing your pea seeds, your plants should be about 6-8 in. (15-20 cm.) tall. Your clipped shoots will be comprised of the long tendril plus one pair of leaves. Leaving the rest of the growing vine on the plant will encourage it to continue growing, offering you more than one harvest from the same plant.

Storing Peas

There’s nothing like the flavor of a fresh pea, so be sure to use them soon after picking. Waiting will allow their natural sugars to turn into starches. When storing, place unwashed peas in a perforated bag or container in the refrigerator. They will stay in good shape for up to five days.

For longer storage, freezing is your best option. Shell your peas if necessary, then blanch them in boiling water for 1-2 minutes, then immediately cool in ice water. Drain thoroughly, pat them dry and freeze in airtight containers or freezer bags.

Propagating Peas

Peas are propagated almost exclusively by seed because pea seedlings dislike their roots being disturbed. Save some money by saving seeds from your favorite healthy pea plants. Allow a few healthy pods to remain on the vine well past the normal eating stage, letting the pods fully mature. Let them dry on the vine and turn brown. The peas inside will become hard.

Once the pods are fully dry, remove them from the plant and remove the hard peas from the pod. Spread the seeds out onto a sheet pan for several days to ensure they are completely dry before storing. Store saved pea seeds in a cool, dark, dry place in an airtight container or paper envelope. Properly stored seeds can remain viable for several years. Keep in mind that open-pollinated and heirloom varieties will grow true from saved seed, while hybrid varieties may not produce plants identical to the parent plant.

Pea Problems

Like any crop you plant in your garden, your peas are subject to pests and diseases that may impact their success.

Common Pests

There are a number of pests that can damage pea plants while you are awaiting harvest.

• Aphids suck the sap of the plant, resulting in fewer pods and weak and stunted plants.
• Pea weevils emerge in spring and lay their eggs in the peas seeds, and once hatched, the larvae eat holes into the seeds.
• Armyworms
• Leaf miners
• Nematodes
• Spider mites

Common Diseases

Some of the common diseases lurching in the air and soil that can impact your pea crop include:

• Powdery Mildew
• Pea Ascochyta Blight
• Pea Aphanomyces Disease
• Pea Streak Virus
• Bacterial Pea Blight

Growing Peas in Containers

Peas are well suited to container growing, making them a great option for patios, balconies, decks, and other small-space gardens. Most varieties can be grown successfully in pots, although dwarf and bush types are especially popular because they stay compact and require less support. Containers should be at least 12 inches (30 cm) wide with good drainage holes, and they should be filled with fertile, well-draining potting mix. Since peas are climbing plants, even compact varieties benefit from a small trellis, stakes, or netting for support.

It’s vital to keep in mind that container plantings will dry out more quickly than in-ground gardens, so peas planted in pots will need more frequent watering, especially in sunny or windy conditions. Keep the soil evenly moist but not soggy, and place containers where plants will receive at least 6–8 hours of sunlight daily. A layer of mulch can help retain moisture and regulate soil temperature. Because nutrients leach out more quickly in containers, occasional feeding with a low-nitrogen fertilizer may also help support healthy growth and pod production.

Growing Peas Indoors

Peas can be grown indoors successfully with enough light, cool temperatures, and the right container setup. Dwarf, snap, and snow pea varieties are especially well suited for indoor growing because they stay relatively compact and adapt well to pots. Containers should have good drainage and be filled with a fertile, well-draining potting mix. Since peas dislike root disturbance, seeds are usually sown directly into this final container rather than transplanted later.

Light will be your biggest challenge. Plants need about 8–10 hours of bright light daily, either from a sunny south-facing window or supplemental grow lights. Peas also prefer cooler indoor temperatures, generally between 55–70°F (13–21°C). Supplemental lighting in a cool basement would be the way to go with growing peas indoors.  

Companion Planting Peas

Companion planting with peas can help maximize garden space, improve plant health, and create a more diverse growing environment. Because peas naturally fix nitrogen in the soil through beneficial root bacteria, they are often planted near crops that benefit from added nitrogen. Good companions for peas include leafy greens like lettuce and spinach, root crops such as carrots and radishes, and vegetables like cucumbers, beans, potatoes, and brassicas including broccoli and cabbage. Aromatic herbs like mint and cilantro are also considered good companions.

Not all plants grow well near peas. Avoid members of the allium family—such as onions, garlic, and chives—because they may interfere with pea growth. Gladiolus is another plant often listed as a poor companion for peas, so keep this summer-flowering bulb away.
