How to Grow Simply Salad Mixes in South Africa

Quick Grow Facts

• Series: PanAmerican Seed SimplySalad multi-species multi-pellet mixtures.
• Products: Summer Picnic and Wonder Wok. The separately sold all-kale Kale Storm mixture has its own Kale Grow Guide module.
• Seed form: Each pack quantity is a pellet count, not an individual-seed count. Pelleting does not prove that the seed is chemically untreated.
• Pretreatment: None required. Keep each pellet whole; do not crush, peel, split or soak it.
• Sowing depth and light: Follow the current packets at 3 mm. Give a light cover; light is optional during germination and bright light is needed as soon as shoots appear.
• Germination: Breeder-controlled culture gives 2–3 days at 18–23°C; current local packets give 10–14 days. For home sowing, allow the full packet window and do not discard a slow pellet early.
• Moisture: Keep the fine seed mix consistently moist until the pellet has fully softened and broken down, but never saturated.
• Method: Direct sowing into the final pot is simplest. Tray sowing is suitable when the whole cluster is transplanted young and intact.
• Spacing: One pellet per 10–15 cm pot; several pellets distributed through larger bowls; 20–30 cm between clusters for mature mounds or 10–15 cm for a short-lived baby-leaf trough.
• Growth form: Compact, mounded mixed foliage, about 30 cm high and wide if allowed to mature.
• Best growing temperature: About 17–21°C by day and 13–16°C by night after establishment.
• Harvest: Breeder material gives 2–4 weeks from transplant for a saleable young-leaf container; local packets give 60–90 days. Use leaf size and tenderness rather than averaging those different outcomes.

Simply Salad Summer Picnic Mix

Shop Simply Salad Summer Picnic Mix Seeds.

Summer Picnic is a multi-species multi-pellet mixture of red and green lettuces, botanically Lactuca sativa. It is selected for greater heat tolerance and later bolting than a typical lettuce mix, but it still produces its best colour, texture and sweetness in cool conditions.

• Composition: Red and green lettuces. Component cultivar names, proportions and fixed-versus-lot-variable formulation are not published.
• Seed count: Exact-mixture breeder material lists 10–12 seeds per pellet, while a newer general SimplySalad seed-form table gives 6–10. Treat the current pack as five or 100 pellets and do not promise a seed or seedling count.
• Spacing and growth form: Allow 20–30 cm between mature clusters. The mixed foliage forms a mound about 30 cm high and wide.
• Harvest outcome: Pick outer leaves for a loose, ongoing harvest or take a baby-leaf cut while the mix is tender. Heat tolerance is relative; strong heat can still make lettuce bitter and trigger bolting.

Simply Salad Wonder Wok Mix

Wonder Wok is a multi-species multi-pellet mixture of Asian greens described by the breeder as mustards, kale and bok choy. Kale belongs to Brassica oleracea and bok choy to the Brassica rapa Chinensis Group. The mustard component may include more than one Brassica species, so its exact botanical identity is left open.

• Composition: Mustard greens, kale and bok choy. Component cultivar names, mustard species, proportions and fixed-versus-lot-variable formulation are not published.
• Seed count: Archived exact-mixture breeder material lists 10–12 seeds per pellet, while a newer general SimplySalad seed-form table gives 6–10. Treat the current pack as five or 100 pellets and expect variable emergence.
• Spacing and growth form: Allow 20–30 cm between mature clusters. Different leaf shapes and growth rates within one mound are normal.
• Harvest outcome: Pick young leaves for salads or harvest slightly larger leaves for quick cooking and stir-fries. The larger kale leaves can remain firmer than bok choy or mustard leaves.

When to Sow Simply Salad Mixes in South Africa

These are practical cool-season starting windows. Shift them for altitude, frost pockets and local heat; the breeder's 17–21°C growing range is more useful than a national season label.

Winter-rainfall Western Cape

Sow from March to May for autumn and winter leaves, then again from August into early spring. Use free-draining containers during prolonged rain, water at soil level and keep air moving. Summer Picnic can extend further into spring than a typical lettuce mix, but afternoon shade becomes useful as days warm.

Frost-prone Interior

Sow from late February to April for an autumn crop where hard frost arrives late, or from July under protection through September for late-winter and spring leaves. Protect trays and new clusters from hard frost. Finish spring batches before persistent heat pushes lettuce to bolt and mustard greens to become stronger tasting.

Humid Coast and KZN Midlands

Sow mainly from April to August, using the coolest and least humid local window. Give morning sun, afternoon shade in warm districts, open spacing and early soil-level watering. Remove yellow or spotted leaves promptly and avoid leaving dense foliage wet overnight.

Hot-dry or Subtropical Interior

Sow from March to July, concentrating on the coolest reliable months. Use a broad, well-drained pot, mulch around established clusters without covering crowns and provide afternoon shade. Keep irrigation steady because a dried pellet can stall before emergence and heat-stressed leaves become bitter or coarse.

How to Sow Multi-Species Pellets

1. Fill a clean pot or cell with fine, free-draining seed mix around pH 5.8–6.2. Pre-moisten it and let excess water drain.
2. Place one intact pellet on the surface. Do not crush or separate it.
3. Cover 3 mm deep as stated on the current packets, firm very gently and mist or bottom-water without displacing the pellet.
4. Keep the seed zone consistently moist at about 18–23°C. The coating must soften fully; alternate drying and flooding can trap or rot seedlings.
5. Give emerging shoots bright light and airflow immediately. Rotate containers so the mixed cluster does not lean.
6. Do not thin the cluster to one plant. Remove only a dead, diseased or severely overcrowded seedling with clean scissors; thinning by leaf type changes the intended mix.

Containers, Direct Sowing and Transplanting

Direct sow one pellet into a 10–15 cm pot, three or four pellets distributed through a 20 cm bowl, four or five through a 25 cm bowl, or five or six through a 30 cm bowl. Use drainage holes and leave space between clusters rather than piling pellets in the centre.

In a broad trough or bed, use 10–15 cm between clusters for a short baby-leaf crop, or 20–30 cm where mounds will mature. The closer spacing needs earlier cutting and more airflow; it is not suitable for letting every component reach full size.

For trays, use one pellet per cell. Transplant after two to three weeks, once roots hold the plug and the seedlings have their first true leaves. Harden the cluster for five to seven days, keep the root ball intact and plant at the same depth without burying growing points.

Water, Feeding, Light and Healthy Growth

• Water: Keep moisture even, especially while the pellet dissolves and after a cut. Water the soil early in the day and empty standing saucers.
• Light: Use full sun in cool weather and partial or afternoon shade as temperatures rise. Too little light produces stretched, soft leaves.
• Soil: Use fertile, free-draining potting mix or garden soil enriched with mature compost. Never put fresh manure against edible leaves.
• Feeding: Feed lightly and regularly after establishment or cutting. Excess nitrogen makes soft, disease-prone growth and can weaken colour.
• Airflow: Give clusters room, remove dead leaves and avoid repeated overhead watering in humid weather.
• Temperature compromise: The shared 18–23°C germination range suits the pellet as a whole. Individual components can still emerge at different speeds; do not chase one seedling with extra heat.

Baby Leaves, Mature Leaves and Repeat Cutting

For baby leaves, begin when the cluster is well rooted and leaves are large enough to handle cleanly. Cut in the cool morning with sanitised scissors, leaving about 5 cm and every visible growing point intact. For a steadier mature harvest, pick a few outer leaves from several plants instead of shearing the whole pot.

Cool, healthy clusters may regrow after a light cut, but regrowth is not guaranteed and the different species will not return at the same rate. Water after cutting, feed lightly once new growth starts and stop repeated cutting if crowns are damaged, plants bolt, leaves become tough or disease appears. Replace an ageing lettuce-heavy pot rather than forcing it through summer heat.

The breeder's 2–4 weeks from transplant describes a young finished container; the current packets' 60–90 days suits a more mature harvest window. Leaf size, tenderness and plant health should decide when to pick.

Pests, Diseases and Safe Crop Care

Check seedlings for slugs, snails, cutworms and fungus gnats. Aphids hide in soft centres; caterpillars and flea beetles chew Brassica leaves; leaf miners can mark lettuce and mustard. Hand-pick where practical, use insect mesh and identify the pest before treatment.

Damping-off follows saturated, poorly ventilated seed mix. Downy mildew, bacterial spotting and other leaf diseases spread more easily through dense wet foliage. Use clean containers, rotate edible leafy crops where possible, water at soil level and remove badly affected plants. Use only a control registered in South Africa for the edible crop and identified problem, then follow the label and harvest withholding period exactly.

Why Germination or Establishment Fails

The pellet stays hard

The surface dried out or water ran around the coating. Re-wet gently and keep moisture consistent without flooding.

The pellet turns soft but nothing emerges

It may be too deep, overheated, old or waterlogged. Allow the packet's full 10–14 days, then re-sow 3 mm deep into fresh fine mix if no sound seedlings appear.

Only some leaf types appear

Standard multi-species pellets do not promise identical component emergence. Temperature, moisture and seed condition can favour one component. Do not identify a missing cultivar from foliage or split another pellet to compensate.

Seedlings collapse at soil level

Damping-off is favoured by saturation, dirty pots, weak light and poor airflow. Discard affected clusters, clean the container and re-sow into fresh mix.

The cluster is tall and floppy

Light is too weak, temperatures are too warm or plants are crowded. Increase light and airflow and use the next sowing window.

Leaves are bitter, coarse or bolting

Heat, drought or age has shortened the crop. Harvest promptly, provide shade and sow again in the next cool window.

Regrowth is patchy

The cut was too low, growing points were damaged, one species recovered faster, or heat, root crowding and low fertility slowed the pot. Switch to selective outer-leaf harvest or start a fresh container.
