The workbook confirms a mixture of red, white, pink, and purple radishes but does not provide exact cultivar names or proportions. The fiche therefore invents no variety names. Each sowing may produce roots with slightly different colours shapes and speeds. Harvest each root at its proper size rather than waiting for complete uniformity across the row.

Cycle
Annual for root harvest
Organic ‘Biomix’ radish (Raphanus sativus, mixture) combines spring radishes with red, white, pink, and purple roots. Each sowing provides a visually varied, crisp, lightly pungent crop suited to colourful bunches, crudités, and salads. Because it is a mixture, exact shape, colour, and speed of individual roots may vary; detailed cultivar composition is unconfirmed. The Biologiquement Vôtre workbook lists approximately 200 organic open-pollinated non-heirloom seeds, foliage height of 15–25 cm, and rapid harvest near 25 days.
Direct sow April through September in light loose stone-free well-drained soil, approximately 1 cm deep. Maintain 10–20°C and even moisture; germination generally takes 4–10 days. Thin to approximately 5 cm so each root can size without competition. Full sun suits cool weather while light partial shade may slow drying during warm periods. Repeat small sowings every two or three weeks rather than planting the entire packet at once.
Begin inspecting roots around 20–25 days and harvest once they reach a satisfactory size. Biomix should be picked young to retain tender crisp moderately pungent flesh; roots left too long may become pithy fibrous or very strong. Uncover a shoulder to assess diameter, then lift a sample. Remove tops and cool roots promptly. Serve fresh, sliced in salads, with dip, or briefly roasted. Yield and the proportion of each colour are not guaranteed.
Planting guide
From planting to establishment.
Planting depth
Approximately 1 cm (⅜ to ½ in)
Spacing / density
Approximately 5 cm between plants and 20 to 30 cm between rows
Establishment temperature
10 to 20°C (50 to 68°F)
Establishment time

Best planting time
April through September in small successive sowings
Propagation
Direct sowing
Growing method
Direct sow April through September approximately 1 cm deep in fine loose soil. Maintain 10–20°C and even moisture until emergence in 4–10 days. Thin early to approximately 5 cm by clipping excess seedlings. Repeat small sowings every two or three weeks and pause during strong heat if roots become fibrous. Weed shallowly, water at soil level, and protect from flea beetles if needed. Begin inspecting near 20 days and harvest around 25 days.
Soil and care
The right conditions.
Exposure
Sun to light partial shade
Soil pH
Approximately 6.0 to 7.0
Minimum temperature
-4°C (25°F)
Watering
Keep the surface evenly moist during germination to prevent a crust that blocks seedlings. After emergence water deeply once the top two or three centimetres begin to dry. Alternating drought and heavy irrigation promotes split fibrous or excessively pungent roots while prolonged saturation causes rot. Water at soil level in the morning, mulch lightly after thinning, and avoid unnecessarily wetting leaves. In containers check moisture daily during warm periods without leaving water in the saucer.
Soil type
Prepare light deep loose well-drained soil screened to remove stones clods and debris that distort roots. Slightly acidic to neutral pH around 6.0–7.0 is suitable. Incorporate only a moderate amount of mature compost; fresh manure and excess nitrogen produce excessive foliage and forked or poor-quality roots. Work the bed when neither sticky nor dusty and avoid walking on the row. In heavy soil use a raised bed or sufficiently deep container. Rotate away from other Brassicaceae.
Fertilization
Before sowing incorporate only a moderate amount of mature compost when soil is poor or very sandy. Biomix radish grows quickly and needs little feeding: excess nitrogen produces abundant foliage at the expense of roots, delays their formation, and may encourage less pleasant texture. Do not use fresh manure and never place concentrated fertilizer directly against seed or young roots. If a soil test reveals a deficiency choose a balanced root-vegetable fertilizer, apply a light dose according to its label, then water. In fresh pre-enriched potting mix no additional feeding is normally needed during this approximately 25-day cycle.
Seasonal care
From spring through autumn make small sowings every two or three weeks while weather remains cool. Keep the surface moist until emergence, then thin early to approximately 5 cm without disturbing retained plants. Weed very shallowly and protect young leaves from flea beetles with insect netting if needed. Also monitor slugs, aphids, caterpillars, and signs of rot. Pause sowing during strong heat if roots become fibrous or excessively pungent. Begin inspecting near 20 days, harvest around 25 days, and remove diseased Brassicaceae residues.
Container growing
A controlled environment.
Recommended pot size
10 to 15 L (2½ to 4 gal), at least 25 to 30 cm deep
Choose a broad 10–15 L container at least 15–20 cm deep with several drainage holes. Fill it with light loose stone-free well-drained potting mix. Sow approximately 1 cm deep, then thin to approximately 5 cm so every root can size without competition. Place the container in full sun during cool weather or light partial shade during warm periods. Maintain even moisture without standing water and rotate the container for balanced light. Harvest progressively near 25 days because colours and shapes in the mixture may not all mature at exactly the same pace.

Harvest
Begin inspecting near 20 days and generally harvest around 25 days according to the shape and colour of each mixture component. Gently uncover a shoulder and lift a sample root. Pick while flesh is firm and crisp before it becomes pithy highly fibrous or excessively pungent. Progressively harvest ready roots rather than waiting for perfect uniformity. Remove tops, cool promptly, and discard any root that is soft, mouldy, slimy, or abnormal-smelling.

From the garden to inspiration.
Quick-roasted Biomix radishes — Scrub, rinse, and halve the largest roots. Toss with a little oil, a pinch of salt, and herbs, then roast at high heat until lightly browned but still firm. Add a squeeze of lemon when serving. Small roots may remain raw to create a contrast of texture and colour. Refrigerate ingredients and leftovers within two hours.
Frequently asked questions
Everything toknow.
Direct sow April through September while weather remains cool. Place seed approximately 1 cm deep, maintain 10–20°C, and keep the surface moist; emergence normally takes 4–10 days. Make small sowings every two or three weeks to stagger harvest. During strong heat wait for cooler temperatures to avoid bolting and excessively pungent roots.
Maintain even moisture without saturating soil and harvest roots young, generally around 25 days. Drought followed by heavy watering promotes splitting and strong flavour; prolonged heat also makes flesh more fibrous. Thin to approximately 5 cm, use loose soil, and avoid excess nitrogen. Cool promptly after harvest and separate tops from roots.
Begin checking near 20 days and generally harvest around 25 days. Uncover a shoulder to assess diameter, then lift a sample root. Because the packet is a mixture some colours or shapes may be ready before others. Harvest progressively once each root is firm and crisp. Do not wait until it becomes pithy highly fibrous or excessively pungent.
Yes. Use a broad well-drained 10–15 L container at least 15–20 cm deep. Fill with light stone-free mix, sow 1 cm deep, then thin to approximately 5 cm. Place it in sun during cool weather and maintain even moisture without standing water. Make several small sowings rather than one dense sowing. Harvest near 25 days to free the container for the next batch.
