How to Grow Green Peas - The Complete Guide

Green peas are a rewarding vegetable to grow at home and an excellent addition to any garden. Below we share the basics of growing green peas in a home garden, as well as common mistakes and considerations.

When to Plant Green Peas

Green peas are a frost tolerant vegetable. This means the best time to plant them is mid to early spring, and mid to late summer for a fall harvest. If you’re expecting a late or early frost after planting, protect your green peas with a blanket of straw or cover them with plastic buckets.

If you live in the U.S., check out the Farmer’s Almanac or the USDA’s Plant Hardiness Zones for more help regarding frost and the best dates for planting in your area.

How to Plant Green Peas

Plant your green pea seeds directly in the soil of your garden or container at a depth of 0.5 inches (1 centimetre). Seeds can be planted outside or you can germinate them indoors and transplant them later. Typically, green pea seeds take about 1 - 2 weeks to fully germinate.

If transplanting, the best time to move green pea plants outside is when they reach 3 - 4 inches (7 - 10 centimetres) tall or have at least 3 - 4 true leaves.

When planting green peas in the garden, it’s best to space them 1 - 2 feet (30 - 60 centimetres) away from the nearest plant.

How to Grow Green Peas in Pots

The key to caring for green peas in containers is well draining soil and a pot big enough for their root system. Aim for a pot that is roughly 288 cubic inches (4,719 cubic centimetres) in size. Any old flower pots you have lying around should do the trick.

How Long do Green Peas Take to Grow

On average, it takes about 45 - 55 days for planted green pea seeds to develop into a fully mature plant.

How Big do Green Peas Get

Typically, green pea plants reach about 2 - 3 feet (or 75 centimetres) in height. Though this can fluctuate depending on the variety.

How Much Sunlight do Green Peas Need

Green peas need at least 6 hours of direct sunlight every day in order to thrive. Be careful to place your plants in an area that receives adequate sunlight. Otherwise, they may not mature properly.

How Much Water do Green Peas Need

Green peas like well draining soil that is kept consistently moist, but not wet or soggy. The amount of water it takes to achieve this effect will differ depending on the type of soil available to you.

Be sure to water your green peas on a consistent, steady schedule. This will ensure the plant yields a healthy, uniform crop.

If growing your green peas in pots, they will need to be watered more frequently than green peas planted directly in the garden.

You will know your green peas are in need of more water when their leaves wilt, yellow, and/or the plant begins to droop. But be careful, this can also happen if the plant receives too much water. This is a difficult balance for most novice gardeners. But the more time you spend with your green peas, the better you’ll be able to gauge how thirsty they are.

How to Harvest Green Peas

Green peas are ready to pick when they’re about 2 - 3 inches (5 - 8 centimetres) in size. Leaving a short bit of stem attached, cut the green pea from the plant with a sharp knife or scissors. Be careful to avoid pulling them by hand, as this can cause vines to break.
