Peas are a cool-season crop sown the opposite way to beans: direct sow as soon as soil can be worked in late winter or early spring (they germinate at 4-5°C and shrug off frost), 5cm apart along a light trellis or netting. Harvest in 55-70 days, picking every couple of days — sugars convert to starch within hours of picking, which is why homegrown peas taste so much better. Heat above ~27°C ends the crop. A seed packet costs $2-4.
Key facts
- A true cool-season crop: sow in early spring (or autumn in mild climates) — seeds germinate in soil as cold as 4-5°C and seedlings tolerate frost, but plants collapse in summer heat.
- Always direct sown — peas resent root disturbance and grow fast enough that transplanting gains nothing.
- Three types: shelling peas (eat the seeds), snap peas (eat pod and all), and snow peas (flat edible pods picked young).
- Pea sugars start converting to starch within hours of picking — the reason garden peas eaten same-day beat anything in a supermarket.
Care requirements#
| Plant type | Outdoor cool-season annual legume, climbing by tendrils |
| Growing medium | Any well-drained soil with compost; grows in deep containers (30cm+) with netting support |
| Light needs | Full sun; tolerates light shade better than most vegetables, useful for late-spring sowings |
| Water frequency | Modest until flowering, then consistent — about 2.5cm (1in) per week during pod fill |
| Sowing season | Northern hemisphere: direct sow Feb-Apr (and again late Jul-Aug for an autumn crop). Southern hemisphere: Jul-Sep and Feb-Mar. In mild-winter/subtropical climates, sow through winter |
| Spacing | 5cm apart in double rows 20cm apart, along netting or twiggy sticks; rows of supports 60-75cm apart |
| Support | Light netting, chicken wire, or branched 'pea sticks' 60-180cm tall depending on variety — tendrils grip thin supports, not thick poles |
| Temperature range | Thrives at 13-18°C (55-65°F); seedlings tolerate frost, production stops above ~27°C (80°F) |
| Fertilizer | Almost none — legumes fix their own nitrogen; a little compost at sowing is enough |
| Soil pH | 6.0-7.5 |
| Container suitability | Good — dwarf varieties like 'Tom Thumb' or snap peas on a balcony trellis |
| Toxicity | Garden peas non-toxic. Do not confuse with sweet pea (Lathyrus odoratus), the ornamental, whose seeds are toxic |
Growth & propagation#
| Days to harvest | 55-70 days from sowing; snow peas earliest (picked flat), shelling peas latest |
| Yield per plant | Roughly 0.5-1kg of pods per metre of double row; individual plants modest, so sow generously |
| Edible parts | Seeds (shelling), whole pods (snap/snow), plus shoots and tendrils as salad greens |
| Propagation methods | Direct-sown seed, 3-5cm deep; pre-soaking overnight speeds germination in dry soil |
| Harvest cue | Snow peas: flat pods 5-7cm. Snap peas: plump but glossy. Shelling: pods filled but still bright green — pick every 1-2 days |
| Storage | Eat or freeze fast — sweetness fades within hours; blanched peas freeze extremely well |
Common problems & troubleshooting#
| Symptom | Likely cause | Fix |
|---|---|---|
| Seeds vanish or seedlings snipped at soil level | Mice and birds eating seed, or slugs on emerging shoots | Sow deeper (5cm), cover rows with netting or wire until 10cm tall, and run slug defenses in damp springs |
| White powdery coating on leaves late in the season | Powdery mildew, worst in warm dry weather on aging plants | Water the roots not the foliage, choose resistant varieties, and accept it on spring crops that are nearly finished — sow autumn crops earlier |
| Plants yellow and collapse from the base | Fusarium wilt or root rot in cold, waterlogged soil | Improve drainage, rotate legumes on a 3-4 year cycle, choose wilt-resistant varieties |
| Small white maggots inside pods | Pea moth larvae — eggs laid on flowers | Cover flowering plants with fine mesh, or time sowings so flowering misses the moth's early-summer flight window |
| Flowering stops and vines brown in early summer | Heat — peas naturally finish above ~27°C | Nothing to fix: harvest what's set, pull plants, and resow in late summer for an autumn crop |
Sow the moment your soil wakes up
Sodate tracks your local soil-temperature window so you sow peas at the first workable moment — weeks earlier than most gardeners dare.
Seasonal care#
Varieties & cultivars#
| Variety | Distinguishing trait | Note |
|---|---|---|
| 'Sugar Snap' (snap) | Thick, sweet, fully edible pods on tall vines | The variety that popularized snap peas |
| 'Oregon Sugar Pod II' (snow) | Flat pods, mildew resistant, semi-dwarf | Reliable and productive |
| 'Kelvedon Wonder' (shelling) | Early dwarf shelling pea, classic UK favourite | Good for successional sowing |
| 'Tom Thumb' | 20-25cm dwarf, no support needed | Ideal for pots and window boxes |
Buying checklist#
- Buy seed, not seedlings — peas direct-sow better and hate root disturbance
- Choose your type deliberately: shelling, snap, or snow — the harvests are completely different
- Check mature height on the packet (20cm dwarfs to 2m climbers) and match your support
- Wrinkle-seeded varieties are sweeter; round-seeded ones are hardier for the earliest/latest sowings
- Mildew-resistant varieties for late-spring and autumn sowings

Often confused with#
Name confusion warning#
"Sweet pea" does not mean an edible pea. Lathyrus odoratus, the ornamental sweet pea, has toxic seeds and pods, and its seedlings look very similar to garden peas. Buy edible pea seed from the vegetable section and check for Pisum sativum on the packet.
Where it's actually grown#
Nearly all garden pea seed is field-grown in cool, dry-summer regions — the Palouse of Idaho/Washington, plus New Zealand and Tasmania, which supply much of the world's off-season and counter-season pea seed. Seedlings are rarely sold; direct sowing is standard everywhere.
Import & biosecurity restrictions#
| Region | Note |
|---|---|
| Australia | Pea seed imports regulated for seed-borne viruses; permits required. Live plants cannot be imported personally — domestic seed is abundant. |
| US | Domestic sale unrestricted; personal imports may need a USDA small-lots permit. |
| UK | Home seed imports generally fine; commercial lots need phytosanitary certificates. |
| India | No domestic restriction; peas are a major winter (rabi) vegetable crop across north India. |
| Canada | CFIA commercial seed rules apply; home packets clear routinely. |

Frequently asked questions
When should I plant peas?
As early as your soil can be worked in late winter or spring — pea seed germinates at 4-5°C and seedlings tolerate frost. In hot-summer climates, sow again in late summer for an autumn crop.
Do peas need a trellis?
Most varieties yes, but a light one — netting, chicken wire, or twiggy sticks that thin tendrils can grip. Dwarf varieties like 'Tom Thumb' need no support at all.
Should I start peas indoors and transplant?
No — direct sow. Peas dislike root disturbance, germinate in cold soil, and grow fast enough that transplanting gains nothing.
What's the difference between snap peas, snow peas, and shelling peas?
Shelling peas are grown for the seeds and the pod is discarded; snap peas have thick, sweet, fully edible pods; snow peas are picked as flat young pods, common in stir-fries.
Why did my peas stop producing in summer?
Heat — peas are a cool-season crop and shut down above roughly 27°C. Pull the vines and resow in late summer for an autumn harvest.
