Growing Peas – How to Plant, Grow, and Harvest Peas

Growing peas may not be the most efficient use of space if your goal is producing the maximum calories. That said, the flavor of home grown garden peas knocks the socks off most commercial peas.

If you want more yield per square foot, grow snap peas so you can eat the pod and the peas inside. Pea plants are also great to include in your garden rotation because they can help add nitrogen to the soil.

In this post we’ll cover pea growing from planting to harvest, including companion plants, pea trellis and troubleshooting tips.

Planting Peas – How to Get Your Peas Off to a Strong Start

Peas should go in the ground early, but there’s a point where “early” turns into “too early.”

Here are the basics to keep in mind when planting peas:

• Preferred soil pH: 6-7
• Full sun is best in cool climates (a little afternoon shade helps in warmer areas)
• Plant seeds about 1 inch deep
• Space about 2 inches apart
• I like double rows, 8–10 inches apart, with a trellis between
• Soil temp: 40–75°F (warmer soil = faster germination)

You can inoculate seeds with nitrogen-fixing bacteria if you like. If the area has had beans or peas before, the bacteria is probably already in the soil.

What are the Best Peas to Grow?

I’ve tried quite a few varieties over the years, but I keep coming back to a couple favorites:

• Green Arrow for shell peas
• Super Sugar Snap for snap peas

I’m not much of a snow pea fan, so they rarely make it into my garden. If you’re unsure what to grow, ask around locally. What thrives in your area matters more than what looks good in a catalog.

Don’t Rush to Plant Peas in Cold Ground

Peas are known as an early crop, but planting too early can cause problems. If the soil is too cold, germination slows way down—and seeds may rot instead of sprouting.

There’s a big difference between:

• Soil at 60°F → quick germination
• Soil at 40°F → very slow germination

If your soil is still cold and soggy, it’s worth waiting a bit or using black fabric or plastic to warm things up. Once established, peas handle cool weather just fine—but they don’t love getting started in icy conditions.

Starting Peas Indoors (Yes, You Can)

Peas are usually direct sown, but I’ve had good luck starting an early batch indoors.

• Plant seeds about 1 inch deep
• Space about 2 inches apart
• Transplant when they’re still small (2–3 inches tall)

The key is not letting them get too big before transplanting. Small plants handle the move much better.

Pre-Sprouting Pea Seeds

If you want to speed things up, you can sprout your seeds before planting. Soak them overnight, then keep them moist in a jar or between damp cloths. Rinse daily, and plant once the root just starts to emerge.

This can be especially helpful in cool soil, where seeds might otherwise sit and sulk.

Planting Peas in the Garden

Getting your soil ready ahead of time makes a big difference. In the fall before planting, I like to add compost or aged manure and, if possible, use a cover crop. If you’ve used legumes as a cover crop, you’re already building the biology peas need.

When it’s time to plant:

• Dig two shallow trenches about 8 inches apart
• Inoculate seeds if desired
• Cover lightly and firm the soil
• Water gently (so you don’t wash everything away)

Fall Planting Option

You can also plant peas for a fall crop. Just keep in mind:

• Soil temps above 75°F can stop germination
• Mulch or shade can help cool the soil
• In warmer climates, peas may actually do better as a fall or winter crop

See our Printable seed starting calendar for help estimating your pea growing dates.

Companion Plants for Peas

Peas play nicely with most of the garden.

Good companions include:

• Carrots
• Cucumbers
• Corn
• Potatoes
• Salad greens
• Flowers like marigolds and alyssum

Some sources suggest avoiding growing peas with onions and garlic. That said, I’ve tucked onions along the edge of pea rows to discourage rabbits, and both did fine. As long as the ground is fertile and the onions aren’t too close, both do fine.

Growing Peas – Care During the Season

Once your peas are up, things get pretty straightforward. I usually mulch and trellis right away. Waiting too long to set up support can leave you with a tangled mess that’s hard to fix later.

Mulching Peas

My go-to method:

• Damp newspaper layer
• Topped with straw

It cuts down on weeds dramatically and helps keep the soil cool, which peas appreciate. Just be mindful of where your mulch comes from. Hay, manure, or straw can sometimes carry herbicide residues.

Pea Trellis Basics

If you’re growing peas, I strongly recommend using a trellis. (The exception would be growing peas that are bred for container gardening.) The plants naturally grab onto whatever is nearby with their tendrils, so once they find support, they take care of the rest.

As mentioned above, I plant in double rows with the trellis in the middle. That keeps everything contained and easier to manage. Strong winds (or the weight of full grown vines) will topple a fence that is not well supported. Don’t be skimpy with your trellis.

For support:

• Short varieties: sturdy fence or low trellis, braced every 3-4 feet
• Tall varieties: netting, arches, or cattle panels

See Pea Trellis Ideas for a Bigger, Easier Harvest for more trellis information.

Pea Fertilizer

Even though peas fix nitrogen, they don’t do it right away. A light boost early on helps get them off to a strong start. Side dress with compost or balanced fertilizer when plants are a few inches tall.

Avoid high-nitrogen inputs like fresh manure, or you’ll get lots of vines and not many peas.

Watering your Pea Plants

If you use mulch, about half an inch of water per week is usually enough. Morning watering is best to help prevent diseases like powdery mildew.

Pea Flowers, But No Pods?

If your plants are flowering but not producing, they may need a little help with pollination. Try gently shaking the plants or brushing flowers with a soft brush. It doesn’t take much—just enough to move pollen around.

Pea Diseases

Like most garden crops, peas can run into fungal or bacterial issues.

Your best defenses:

• Good airflow
• Trellising
• Healthy soil
• Mulch to reduce splash-up

Watering with compost tea can also help by supporting beneficial microbes on the leaf surface. The healthier your pea plants, the more resistant they will be to diseases.

How to Harvest Peas (and When)

Harvesting regularly keeps the plants producing. Use one hand to hold the vine and the other to gently pull the pod free. Avoid ripping or tearing the pea plant. Pick every day or two once they start producing.

If you miss a few and they get overripe, go ahead and remove them anyway. Leaving them on the vine signals the plant to slow down.

Harvest Timing by Type

• Snow peas: Pick when pods are full size but still flat
• Snap peas: Pick when pods are plump and crisp
• Shell peas: Pick when pods are full but not bulging or wrinkled

Eat Them Fresh (Really Fresh)

Peas are one of those crops where timing matters. After harvest, sugars quickly start converting to starch. That’s why grocery store peas never quite measure up.

For best flavor:

• Eat within a few hours, or
• Blanch and freeze right away (See “How to Freeze Peas“)

Snap peas and snow peas are more forgiving than shell peas, and will hold longer in the refrigerator. If we find overripe peas, we sort them into a different container and designate them as “soup peas”. We freeze them and use them in dishes like vegetables soup where the fresh pea flavor isn’t as important.

Final Thoughts on Growing Peas

Growing peas isn’t about maximum efficiency. It’s about flavor, soil health, and that first handful of sweet peas eaten straight from the garden. They’re easy to grow, forgiving once established, and a great way to kick off the gardening season.
