How to Grow Peas in South Africa: Greenfeast and Oregon Sugar Pod II

Quick Grow Facts

• Crop: Cool-season annual edible pea, Pisum sativum.
• Types: Greenfeast shelling pea; Oregon Sugar Pod II flat-podded snow pea.
• Seed form: Raw seed; treatment status is not confirmed by the sale-form wording.
• Depth and light: Current packets say 10 mm. Cover the seed fully; light is not required until shoots emerge.
• Germination: Expect 7–14 days around 15–20°C. Peas can germinate in cooler soil, but emergence slows and wet seed becomes more vulnerable to rot.
• Pretreatment: No soaking, chilling or scarification is required. Pre-water the bed and sow dry unless the physical packet expressly says otherwise.
• Method: Direct sowing is preferred because peas dislike prolonged root disturbance.
• Spacing: Current packets say 5 cm between plants and 60 cm between rows.
• Support: Install 60–90 cm twiggy support or netting before the vines lean; both compact cultivars are easier to harvest upright.
• Best growth temperature: South African government guidance gives about 13–18°C; heat reduces yield and eating quality.
• Water: Keep the root zone evenly moist and never saturated, with special attention from flowering through pod fill.
• Harvest: Shell Greenfeast from plump pods; pick Oregon Sugar Pod II while pods are broad and flat, before peas enlarge.

Greenfeast Shelling Pea

Shop Peas Greenfeast Seeds.

• Type and cultivar: Open-pollinated Greenfeast shelling or garden pea, Pisum sativum.
• Growth form: Compact short vine. South African and supplier sources place it around 60–77 cm, so low support is useful.
• Flowers and pods: White flowers are followed by medium-green shelling pods, commonly carrying about six to eight peas.
• Spacing: Follow the current packet at 5 cm in the row and 60 cm between rows.
• Timing: The packet lists 120 days. Cultivar sources report roughly 70–90 days under favourable production conditions. Do not average the figures into a promise: cool weather, frost, heat and moisture all shift maturity.
• Harvest outcome: Pick when pods are plump and well filled but still bright green, then shell. The pod is fibrous and is not the intended edible part.

Oregon Sugar Pod II Snow Pea

Shop Peas Oregon Sugar Pod II Seeds.

• Type and cultivar: Open-pollinated Oregon Sugar Pod II snow pea, Pisum sativum, bred for tender flat edible pods.
• Name note: The authoritative cultivar spelling ends in the Roman numeral II. The current store handle and product title retain “ll”; this guide does not change those catalogue identifiers.
• Growth form: Compact bush or short vine, about 60–75 cm. A low trellis improves picking, airflow and pod cleanliness.
• Spacing: Follow the current packet at 5 cm in the row and 60 cm between rows.
• Timing: The packet lists 60–120 days; university cultivar sources commonly place first harvest around 60–70 days in suitable cool conditions.
• Disease response: Oregon State University sources report resistance to pea enation mosaic virus and other pea diseases. Resistance lowers risk; it does not provide immunity or replace rotation, airflow and aphid control.
• Harvest outcome: Pick while pods are broad, flat, tender and bright green, before the peas inside become round and prominent. Harvest every day or two at peak production.

When to Sow Peas in South Africa

Winter-rainfall Western Cape

Sow from April to August, with the most reliable batches established once autumn soil has cooled. Use a raised or free-draining bed where winter rain saturates the ground, and leave enough airflow for wet weather. Finish later sowings early enough to flower and fill pods before hot, dry spring wind and summer heat reduce quality.

Frost-prone Interior

Sow from July to September as the worst hard frost begins to ease. Pea seedlings tolerate brief light frost better than flowers and young pods, so use frost cloth during severe nights and avoid an exposed frost pocket. Aim to finish the crop before early-summer heat. In very cold districts, a late-winter sowing is safer than an autumn crop that flowers during hard frost.

Humid Coast and KZN Midlands

On the warm humid coast, sow from March to June. In the cooler KZN Midlands, June to July is usually more reliable, adjusted for local frost pockets. Give the plants morning sun, a full 60 cm between rows, support and good airflow. Water at soil level early in the day so foliage is not wet overnight.

Hot-dry or Subtropical Interior

Sow from March to June as the hottest conditions pass, concentrating on the coolest practical local window. Use dependable irrigation and mulch only after seedlings establish. In reliably frost-free gardens, small succession sowings two weeks apart can extend harvest, but stop once the crop would flower in sustained heat.

How to Sow and Establish Peas

1. Choose full sun in cool weather and well-drained soil with mature compost. Peas prefer roughly pH 5.8–7.0.
2. Install low trellis netting or twiggy support before sowing so later stakes do not damage roots.
3. Water the bed, allow excess water to drain, then sow the raw seed dry and 10 mm deep as stated on the current packets.
4. Space seeds 5 cm apart in rows 60 cm apart. For an intensive supported bed, use two rows 10–15 cm apart on opposite sides of one trellis while retaining 5–10 cm between final plants and a clear path around the bed.
5. Keep the seed zone evenly damp, not wet. Give shoots full sun and gentle airflow as soon as they emerge.
6. If more than one seedling emerges in a station, cut the weaker one at soil level once the stronger plant has its first true leaves. Do not pull and disturb neighbouring roots.

Direct sowing is the safest method. If birds, rodents or severe weather make a protected start necessary, use one seed per deep individual cell, move it while young at one to two true leaves, keep the root ball intact and harden it for five to seven days before planting out.

Soaking, Inoculant and Nodulation

Soaking can shorten germination in some extension trials, but it is not necessary for these products and the current media does not confirm that every lot is chemically untreated. Pre-water the bed and sow dry. Only consider a short soak if the physical packet expressly confirms that the lot is untreated and permits it; sow immediately and never leave swollen seed sitting in water.

A fresh inoculant labelled for peas and containing a compatible Rhizobium leguminosarum strain is optional where peas have not grown recently. It is not a germination treatment and it does not replace good soil. Check product expiry, storage and compatibility with any seed treatment. Four to six weeks after emergence, healthy active root nodules are pink to red inside. White or absent nodules can signal ineffective bacteria, excess soil nitrogen, acidity, drought or waterlogging.

Watering, Feeding and Support

• Water: Irrigate deeply enough to moisten the root zone, then allow the surface to begin drying before watering again. Never leave peas in saturated soil.
• Critical stage: Moisture stress after flowering causes flower and pod abortion, smaller peas, tougher pods and poorer quality.
• Feeding: Work in mature compost before sowing and use a soil test where possible. Avoid heavy nitrogen feeding, which encourages leaves, suppresses nodulation and delays flowers and pods.
• Support: Use 60–90 cm mesh, short stakes with string or twiggy branches. Guide tendrils gently; do not tie soft stems tightly.
• Airflow: Keep weeds down with shallow cultivation and avoid dense, wet foliage, especially on the humid coast and during Western Cape winter rain.

Frost, Heat, Flowering and Harvest

Peas grow best near 13–18°C. Young plants can recover from brief light frost, but hard frost can damage stems and flowering or pod set may pause. Flowers and young pods need more protection than established foliage. At the other extreme, hot conditions shorten the crop, reduce yield and sweetness, and can increase Fusarium wilt pressure once soil warms above about 21°C.

South African government guidance places garden-pea harvest about 18–21 days after flowering, but cultivar, temperature and water supply change the date. Check the pods instead of relying on days alone: shell Greenfeast when pods are full but still tender and green; pick Oregon Sugar Pod II before seed swelling rounds out the pod. Harvest in the cool morning and chill peas promptly because sweetness declines after picking.

Pests, Diseases and Safe Crop Care

Watch emerging rows for cutworms, slugs, snails, birds and rodents. Inspect soft shoots and flower clusters for pea aphids, which can spread enation mosaic and other viruses. Pea weevil larvae can enter young pods. Use netting, hand removal, weed control and a strong water spray for light aphid infestations before considering a pesticide.

Root rot and damping-off are most likely in compacted, wet soil. Powdery mildew increases late in the crop and where airflow is poor; prolonged humidity and leaf wetness favour other foliage diseases. Rotate peas and other legumes out of the bed for two to three seasons where space allows, remove badly diseased debris and do not work among wet plants. If treatment is necessary, use only a product registered in South Africa for edible peas and the identified problem, follow the label exactly and observe the harvest withholding period.

Why Germination, Establishment or Pod Set Fails

No emergence

The seed zone was too cold, dried out, stayed saturated, crusted over, or pests removed the seed. Re-sow 10 mm deep into evenly moist, free-draining soil.

Swollen seed turns soft

Waterlogging, unnecessary soaking or cold wet soil encouraged rot. Improve drainage and sow dry into a pre-moistened bed.

Seedlings yellow or stop

Check compacted soil, root rot, acidity, cold roots and waterlogging before adding fertiliser. Excess nitrogen can make the problem worse.

Plants fall over

Support was installed too late or is too smooth for tendrils. Add low mesh or twiggy branches carefully without spearing the root zone.

Lots of leaves but few flowers

Too much nitrogen, shade or an unsuitable temperature window can delay reproductive growth.

Flowers drop or pods stay empty

Hard frost, heat, dry wind, drought or saturated roots interrupted set. Stabilise moisture and shift the next sowing window.

Pods are tough or starchy

They were picked late, plants were water-stressed or the crop matured in heat. Harvest more frequently and cool the pods quickly.

Leaves curl, mottle or powder

Inspect for aphids and virus symptoms or powdery mildew. Remove badly affected plants, improve airflow and identify the problem before using a registered control.
