Fresh peas, eaten straight from the pod in the garden, are one of the great pleasures of spring — sweet in a way that shop-bought peas never are. Peas are a cool-season crop, one of the first vegetables you can sow in the year, and they are as easy to grow as they are delicious.
Peas like cool weather, a little support to climb, and soil that is not too rich.

Starting seeds
This is a direct-sow crop: the seed goes straight into the garden where it is to grow, and the plants are not transplanted. Prepare a fine, weed-free seed bed, sow at the depth shown on the seed packet, and keep the bed evenly moist until seedlings appear — expect germination in 7–14 days.
Sow too early into cold, wet soil and germination stalls; sow too late and the plants run out of season. Use our frost-date calculator and the hardiness-zone finder to place your sowing window. Zones 11–13 are frost-free, so sowing windows there are set by heat and rain rather than frost — check your local extension service.
Peas are sown direct where they are to grow, as early in spring as the soil can be worked. Sow in a wide drill or a double row and cover well, since birds love pea seed. Germination is quick in cool soil, and a sowing made in late summer can give an autumn crop in milder areas. Soaking seed overnight is sometimes suggested, but sowing into moist soil works just as well.
Transplanting and planting out
Peas are not usually transplanted, though starting a few in pots can help if mice or birds take your seed. The main job after sowing is support: push twiggy sticks or netting along the row when the plants are young, and they will climb on their own. Even short varieties do better with a little support to keep the pods off the ground.
Space plants 2–3 inches apart — crowding is one of the commonest causes of small harvests. Our plant-spacing calculator works out how many plants fit your bed.
Soil and feeding
Peas grow best in rich, well-drained soil with plenty of organic matter. Dig in compost before planting: it improves heavy soil, helps light soil hold moisture, and feeds the soil life that feeds your plants. Aim for a soil pH of 6.0–7.5 — a simple soil test will tell you where you stand, and garden lime or sulfur can nudge pH up or down over a season, so test before you amend rather than guessing.
Feed lightly and steadily rather than in one heavy dose: too much fast nitrogen late in the season pushes leafy growth at the expense of the part you eat. Our fertiliser calculator works out amounts for your bed size, and the soil-volume calculator tells you how much mix a new bed needs.
Watering
Water needs are moderate: keep the soil evenly moist, watering deeply when the top inch or two dries out. Deep, infrequent watering builds deeper roots than a daily sprinkle.
Water at the base of the plant, in the morning, so the leaves dry quickly and the water reaches the roots. Our watering calculator gives a starting point for your bed size, and the watering schedule generator can build a routine around it. A mulch layer cuts evaporation and keeps moisture even.
Sunlight and temperature
Peas need full sun — a spot that gets sun for most of the day. Our sunlight calculator can check your spot.
This crop is rated hardy for cold tolerance, so it stands up to frost and even light freezes, and it is at its best in the cool seasons. In Zones 11–13, which are frost-free, heat rather than cold is the limit — grow it in the cooler months, with afternoon shade in the hottest weather. Our hardiness-zone finder will confirm your zone, and the frost-date calculator gives you the frost dates to plan around.
Pests and diseases
The pests and diseases most often reported on peas are aphids, bean beetles, slugs, cutworms. Healthy, well-watered plants resist attack better than stressed ones, and rotating beds so the Fabaceae family does not repeat in the same spot helps keep soil-borne problems down.
- Aphids — small sap-sucking insects on new growth; wash off with a strong jet of water and encourage ladybirds.
- Bean Beetles — skeletonise leaves, leaving a lacy pattern; hand-pick beetles and check leaf undersides for yellow egg clusters.
- Slugs — chew ragged holes in leaves at night; water in the morning so the surface dries by evening.
- Cutworms — caterpillars that chew through young stems at soil level; a cardboard collar around each stem protects it.
Inspect plants weekly, especially leaf undersides, and act early. Our pest-identifier helper can help identify what you are seeing.
Companion plants
Good companion plants for peas include:
- Marigolds — their roots discourage some soil pests
- Basil — attracts pollinators
- Onions — their scent is said to confuse pests
- Lettuce — shallow-rooted, fills gaps without competing
Our companion-planting finder can suggest more pairings for your bed plan.
Harvesting
Pick peas when the pods are plump and the peas inside are full-sized but still tender — shell one pod to check before you start picking in earnest. Pick regularly and the plants keep producing, but do not leave pods to go yellow and hard, as that slows the whole plant down. Eat or freeze peas the same day you pick them, while they are at their sweetest.
Expect the crop to be ready about 60–70 days after sowing, though weather and variety shift that window by a week or two either way. Our harvest-date calculator works out your expected harvest date from your sowing date, and the vegetable-yield estimator can estimate how much a bed should produce.
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Birds or mice taking the seed | seed left exposed in the soil | Sow a little deeper than you think, cover the row with netting or fleece until seedlings appear, and start a few spares in pots as insurance.. |
| Plants flowering but no pods | hot weather or poor pollination | Peas set pods best in cool weather, so an early sowing is the best prevention. |
| Powdery mildew late in the season | humid, still air as plants age | Space plants for airflow and water at the base. |

Frequently asked questions
When should I plant peas?
Sow once the soil is workable in spring — this crop is rated hardy for cold tolerance, so it can go in early. For zone-specific timing, see zone 3 or zone 6, and check your local extension service for the dates that fit your area.
How long do peas take to grow?
Peas take 60–70 days from sowing to maturity, and seed germinates in 7–14 days. Weather and variety shift the harvest window by a week or two, so judge readiness by look and feel rather than the calendar alone.
How far apart should I plant peas?
Space plants 2–3 inches apart — that is the room a mature plant needs, and crowding means poor airflow and small harvests. Our plant-spacing calculator works out how many fit your bed.
Do peas need fertiliser?
Peas are light feeders and they fix their own nitrogen from the air, so they rarely need feeding. In fact, rich soil gives you lots of leafy growth and fewer pods.
