How to grow peas

Growing peas is rewarding for gardeners of all experience levels. With their sweet, crisp taste straight from the pod, peas are not only delicious but easy to grow. They're one of the first crops you can plant in spring, thriving in cooler temperatures and adding nitrogen to the soil, which benefits your whole garden. Whether you're planting garden peas, sugar snap peas, or snow peas, this guide will help you enjoy a healthy, abundant harvest of homegrown peas.

How to grow peas from seed

Peas grow best when planted directly into the garden from seed. Soak your pea seeds in water overnight to speed up germination. Prepare the planting site by loosening the soil and mixing in compost to boost fertility. Plant seeds about one inch deep in rows or clusters, ensuring good soil contact. Water them gently but thoroughly after planting. Germination typically occurs within one to two weeks, and the young plants will quickly establish themselves. Keep the planting area weed-free, as peas don't compete well with weeds during early growth.

When to plant peas

Peas prefer cool weather, so plant them as soon as the soil is workable in early spring, typically about four to six weeks before the last frost date. In mild climates, peas can also be planted in late summer or early fall for an autumn harvest. Peas germinate best in soil temperatures between 45°F and 65°F (7°C to 18°C). Early planting is essential, as warm temperatures can shorten the growing season and affect yield and quality.

How far apart to plant peas

Plant pea seeds approximately two inches apart in rows spaced 18 to 24 inches apart. Once seedlings emerge, thin them if necessary to maintain at least two inches of spacing between plants. Adequate spacing ensures air circulation, reduces disease, and makes harvesting easier. If planting bush-type peas, slightly closer spacing is acceptable, while climbing peas benefit from slightly more space for their vines to spread out on a trellis.

How much space peas need

Peas don't require a large growing area, but providing adequate spacing is crucial for healthy plant development. Each pea plant should have at least two inches of space in all directions to ensure they receive enough nutrients, water, and sunlight. Rows should be 18 to 24 inches apart, especially for climbing peas that need more airflow. Good spacing helps prevent fungal diseases and ensures easy access during harvesting.

Do peas need a trellis

Most pea varieties, especially climbing or vining types like sugar snap peas, require a trellis or other support structure. Peas climb naturally by sending out small tendrils that wrap around support. A trellis helps plants grow vertically, reduces disease by improving airflow, and makes harvesting easier. Use netting, bamboo stakes, or simple wire trellises to support your pea plants, which will grow healthier and yield more abundantly as a result.

Where to plant peas

Choose a sunny spot for planting peas. They prefer well-drained, fertile soil rich in organic matter. A slightly raised bed or area with good drainage is ideal, as peas dislike soggy conditions that can cause root rot. Peas also grow well in areas that were previously occupied by heavy-feeding crops like tomatoes or squash, benefiting from the improved soil fertility. Avoid planting peas in the same location as beans or other legumes for consecutive years to reduce disease risks.

How much sunlight peas need

Peas thrive with at least six hours of direct sunlight per day. They can tolerate partial shade, especially in warmer climates, but full sun generally produces the highest yields and best-tasting peas. If your garden space is limited, ensure your peas receive morning and midday sun, which is the most beneficial for plant growth. Insufficient sunlight can result in fewer pods and weaker plants.

What temperature peas grow in

Peas prefer cool, moderate temperatures between 45°F and 75°F (7°C to 24°C). They germinate and grow best in cool conditions. High temperatures, especially above 80°F (27°C), can reduce yields and shorten the growing season by causing plants to mature too quickly. If you experience hot summers, plant peas early in spring or later in summer, timing their growth to coincide with the cooler parts of the growing season.

Can peas handle frost

Yes, peas are frost-tolerant and can handle temperatures as low as 28°F (-2°C). Peas planted in early spring often experience a few frosts without harm. While young seedlings benefit from some frost protection (like a row cover), mature pea plants generally withstand light frosts. Extended freezing conditions, however, can damage or kill young plants, so monitor weather forecasts and protect plants if necessary.

How much water peas need

Peas prefer consistently moist soil, requiring about one inch of water per week. Adjust your watering based on rainfall, as peas dislike waterlogged conditions. It's especially important to maintain consistent moisture during flowering and pod development, as insufficient water during this stage can reduce yields. Always water at the soil level to avoid wetting foliage and prevent fungal diseases.

How often to water peas

Water peas deeply once or twice a week, depending on weather and soil conditions. Check soil moisture by inserting your finger one inch below the surface—if it's dry, it's time to water. Peas benefit from steady moisture, especially during dry spells, but avoid daily shallow watering. Maintaining consistent soil moisture encourages strong root systems and healthier plants overall.

How long peas take to grow

Peas are relatively quick-growing, typically ready for harvest 60 to 70 days after planting, depending on the variety. Snap peas and snow peas often mature faster, usually within 50 to 60 days, while garden peas take slightly longer. To ensure a continuous harvest, plant new seeds every two weeks during early spring. Regular planting intervals will provide a steady crop throughout the growing season.

When to harvest/pick peas

Harvest peas when the pods are plump but still tender and bright green. Garden peas should be picked when pods feel full and rounded. Snap peas are best harvested when pods are slightly filled but still tender and crunchy. Snow peas are usually harvested earlier when pods are flat and before peas fully develop inside. Frequent picking encourages the plants to continue producing more pods.

How to harvest/pick peas

Gently pull pea pods from the plant or use scissors to snip them off cleanly. Harvest regularly—ideally every two to three days—to stimulate the plant to produce more pods. Picking peas promptly and often keeps them tender and encourages continuous flowering. Harvesting early in the morning is ideal, as peas are the crispiest and sweetest at this time.

Can you grow peas indoors

Peas can be grown indoors in pots or containers, provided you have sufficient light and space. Position containers near a sunny window or under a grow light. Choose compact varieties or dwarf peas suitable for indoor growing, as they won't require large support structures. Keep indoor peas consistently watered and provide good airflow to avoid fungal diseases common indoors.

How to grow peas in pots/containers

Select a container at least 12 inches deep with drainage holes. Fill it with a quality, nutrient-rich potting soil. Plant pea seeds about one inch deep, spacing them evenly. Provide a small trellis or stake for the peas to climb, ensuring good air circulation around plants. Place the container in full sun, and water consistently to keep the soil moist. Container-grown peas thrive on balconies, patios, or even sunny indoor spaces, providing fresh peas even without a garden bed.
