How to Grow Peas: A Complete Guide

Learning how to grow peas means you'll have a powerhouse of nutrition growing in your garden. All those succulent little pods contain not only a fair amount of protein, but also vitamins A and C. They're a source of beneficial fibre. Peas are always planted as a priority in my spring garden.

You will find that peas are the easiest possible crop to manage, even as a beginner. They require little attention, grow fast, and thanks to their natural ability to withstand frost, can be sown where other crops might not stand a chance. I recall my first pea crop vividly. I hardly did a thing to them, and was rewarded with a mass of sweet, crunchy pods, their first appearance a matter of weeks later.

Peas aren't just for snacking on raw! Toss them into stir-fries for a sweet crunch, blend them into creamy soup, or add them to pasta dishes. I often add the peas from my backyard garden into 2-3 meals every week when I'm harvesting!

Best Time for Planting Peas

Plant peas early enough to 'beat the heat'. They will stand a light frost or two down to 28°F (-2°C). I always sow mine four to six weeks before the last date on which we may expect our spring freeze. That gives them nice cool ground to germinate in before the seedling is liable to be killed by a hard frost of that kind.

Your planting window depends on your location. A gardener in the North wants to plant the moment their soil thaws. Elsewhere, you might be better off making your plantings in the fall after summer heat has broken. My neighbor in Georgia sets out his plants in September for harvests in November. My cousin in Maine waits until the end of April.

Check soil temperature before planting. Pea seeds sprout best when soil temperature is between 40-75°F (4-24°C). Colder soil makes them slow to grow; warmer soil causes them to "run" and makes it hard to start them. I test mine with a kitchen thermometer. Soil at 50°F typically takes 10 days for the seed to germinate, usually.

Peas require full sun for the greatest quantity of pods. Select spots that get 6 hours of direct sunlight per day. Less means fewer flowers, fewer pods, and spindly vines. I never plant in the shade of buildings or trees. In the hot regions of America, a morning with sunshine and afternoon shade is a desirable location.

How to Plant Peas Outdoors

Bring in the soil by mixing in two parts garden soil with one part compost. This ratio permits the roots of the peas to spread out freely, with rich compost giving new life to the soil without overpowering the young plants. I always mix these first into the bed before sowing, for by so doing, the whole bed will be of equal quality.

Dig planting trenches exactly 1 inch (2.5 cm) deep. This depth is essential for sprouting to succeed. Place the seed every 2 inches (5 cm). Rake over to cover. But I measure very carefully, for one plunges them too deep, and that hinders them from coming up; and if one sows them too shallow, they are sure to lie bare.

Once the seeds are in the ground, give them a gentle watering with a fine-rose watering can. This shower will not wash the seed out of the ground, nor will it cause any clumping. I always water after planting. The rain maintains the seeds under the earth, at the same time keeping the earth ample.

Put in the trellises before the seeds germinate. This way, you will avoid harmful, late-in-the-game disturbance of those tender little trays of roots. Put them in as soon as the seeds are planted. The nature of the vining var. is to trail or climb when the time is right for them. I know this for certain because I have learned the hard way.

Pest and Disease Management

As with much of gardening, preventing pests is just as important as addressing problems. Strong, healthy plants are better able to resist challenges in the garden. Start with sufficient airflow gained through proper spacing. I also recommend crop rotation every year. I typically use a row cover early in the season to protect against insects without the need for chemicals. A little prevention goes a long way when saving time and protecting your harvest.

Treat aphids with a soapy water spray. Mix a tablespoon of mild soap with a quart of water and spray it. For powdery mildew, try a milk spray: mix one part milk with nine parts water, and spray at the first sign of the telltale little, hardly discernible white spots. I much prefer these organic solutions because I want my garden to be chemical-free.

You can modify your environment to PUNISH those pestilences! Water the soil, not the leaves, to avoid fern-type diseases. Cover the soil with straw mulch to prevent splashing, space plants to allow for comprehensive sunlight penetration. I prune off lower leaves to allow good air circulation. These little changes render the surroundings inhospitable for the offenders.

Plant companion plants with strong scents near your peas, such as garlic or mint. They will act to repel many common pests, as will marigolds, while radishes will deter the pests from the pea vines. I plant protection companions and principles. They play their part naturally.

Harvesting and Storing Peas

Be aware of the signs for each. Snap peas should be harvested once they are plump and the peas are visible. Snow peas should be picked while they are flat and bright green (don't wait for the peas inside to show at all), and shelling peas should feel full but not hard. I check them daily, as the pods come to full maturity very rapidly, and fruits picked when they are this ripe have the finest flavor and sweetest flesh.

Use sharp scissors to snip the stems above each pod, rather than pulling the pods from the vine, as this will damage the plant. Hold the vine gently with one hand while you snip with the other; I carry my scissors in my harvest basket. This method will keep your plants producing for weeks.

Choose whichever storage method meets your needs: refrigeration keeps them fresh for several days (2-3) in paper bags, freezing preserves them for at least 8-10 months if blanched first, and drying means you can use peas year round in soups. I freeze most of my harvest for winter meals.

Cool peas immediately after picking. Sugars turn to starch quickly at room temperature. Try to keep harvested pods in the shade, or refrigerate them within an hour. I bring along a cooler to the garden. That's how you hold onto that garden-fresh sweetness you've worked so hard to earn.

Step-by-Step Growing Guide

Plant 4-6 weeks before your last spring frost. Prepare the soil by mixing in compost and creating 1-inch-deep trenches. Set seeds 2 inches apart. Cover them lightly. I use my garden trowel and the compost bin for this. Water the row lightly using a fine rose can, so as not to disturb the seed.

Look for sprouts within 7-14 days. If frost threatens, cover seedlings with row covers for protection. Thin plants to a 4-inch spacing when they reach 2 inches in height. Trellises can now be installed. I use bamboo stakes and twine. Check every day for pests like cutworms lurking near stems.

Train vines onto supports from weeks 5 to 6, as rapid growth begins. Water deeply twice weekly if no rain falls. Apply straw mulch around the plants. I carry my pruning shears with me to remove any yellowing leaves. Watch for aphids underneath leaves during this productive growth.

Expect flowers by the seventh or eighth week. If there are no bees to help out, gently shake the plants every day. Increase watering to 1.5 inches a week. I always use a moisture meter to determine when to water, ensuring the ground is well soaked. Provide afternoon shade if the temperature threatens to exceed 80 degrees, as it may cause the blossoms to drop.

You should start harvesting in week 9 or 10. Snow peas can be harvested first when the pods begin to flatten. Use scissors in your daily harvest. Bring along a basket and a cooling pack. I prefer to pick during the morning hours for maximum sweetness and crispness. Also, while the vines are heavily laden, support them to prevent breakage.

5 Common Myths

Conclusion

Extend your pea harvest by succession planting: sow new seeds every 2 to 3 weeks during the cool seasons. Overwinter with cold hardy varieties under protective covers. I keep peas in production all year by rotating between garden beds and containers, resulting in fresh pods beyond the general spring timeframe.

Indulge in the amazing nutritional harvest of fresh peas from your garden. They pack in plant-based protein for muscle building, vitamin C to ward off disease, and fibre for a happy gut. I toss peas through as many meals as I can each day during pea season. More nutrition than many supermarket supplements!

Peas not only provide me with a healthy crop each year, but also serve as a beautiful example of sustainable gardening in action. They fix nitrogen in the soil and actually improve your soil health without the application of chemical fertilisers. And their water requirements are modest - I have noticed a general improvement in soil quality in the beds where peas are grown each year. All in all, peas are definitely a 'green' crop to grow!

Experiment with different varieties to gain a succession of crops. Mix early snow peas with late shelling types and try a few colorful heirlooms, such as purple-podded. I like to trial two or three new cultivars each year. There's plenty of scope to be had, and the search keeps the garden interesting and lengthens the harvest calendar.
