30–60 days

Germination

Germination time

50–70°F (10–21°C)

Spacing & depth

Sow depth
1/4–1/2" (6–12 mm)
Seed spacing
1 in, thin to 4–6 in
Mature plant spacing
4–6 in (10–15 cm)
Row spacing
12–18 in (30–45 cm)

How to plant

Direct-sow into loose fertile soil. Thin ruthlessly at 2 in tall — crowded roots stay pencil-thin. Fall crops are noticeably sweeter than spring ones; frost pushes sugars into the root.

Grower's tip

Turnip greens are as valuable as the roots — snap off outer leaves for cooking without pulling the plant. Best harvest at 2–3 in wide; larger roots turn woody and hot.

Soil preferences

Soil type

Deep, loose, stone-free sandy loam — rocks and clumps fork roots.

pH range

6.0–7.0

Amendments

Avoid fresh manure or heavy nitrogen (causes hairy or forked roots). A light compost and rock phosphate work well.

Watering

Frequency

Steady moisture — 1 in per week. Uneven watering causes cracking.

Method

Deep soaking; avoid shallow daily watering that keeps roots near the surface.

Over vs. under

Overwatered: cracked or rotted roots, foliage disease. Underwatered: woody, hot-flavored, or bitter roots.

Top-water or bottom-water?

Prefers top-watering — Top-water deeply at the soil surface so the whole root zone stays evenly damp — bottom-watering isn't practical in the ground.

Temperature tolerance

Ideal daytime air temp

60–75°F (15–24°C)

Ideal nighttime air temp

45–65°F (7–18°C)

Frost sensitivity

Carrots, parsnips, beets sweeten after frost. Storage roots can often overwinter in the ground under heavy mulch.

Container growing

Container-suitable?

Possible with the right cultivar

Recommended pot size

12+ in deep for full-size carrots and parsnips; 8 in deep is fine for radish and short carrots

Notes

Pick short or round cultivars (Parisian carrots, Chioggia beets) for shallow containers.

Succession planting

Radish every 2 weeks. Carrots and beets every 3–4 weeks spring through late summer.

Detailed harvesting

Loosen soil with a fork before pulling to prevent snapped tops. Twist off greens 1 in above the crown for storage; leave 1 in of stem on beets to prevent bleeding.

Post-harvest storage & preservation

Trim tops; store unwashed in damp sand or perforated bags in the fridge or root cellar at 32–40°F. Most root crops keep 3–6 months.

Culinary, medicinal & other uses

Fresh, roasted, fermented (kraut, kimchi), pickled. Tops of beets, radishes, and turnips are edible greens.

Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.

Seed saving

Pollination

Biennial and insect-pollinated. Root crops cross widely (carrots cross with Queen Anne's Lace).

Isolation needs

1/2 mile in the open or use cage with introduced pollinators.

How to save

Overwinter the best roots; replant in spring; collect the dry umbels/seed stalks in year 2.

Pick your USDA hardiness zone and we'll estimate the key dates for turnip in your area. These are regional averages — always check your own last-frost forecast before sowing.

From your kitchen — grow turnip from what you already have

Root crops are usually biennials — the root is year 1, the seed is year 2. Store your best roots over winter, replant in spring.

  1. 1At harvest, save 5–10 of the best roots and store them cool, damp, and above freezing.
  2. 2In early spring, replant them tops-up at soil level.
  3. 3They'll bolt, flower, and set seed heads later that summer.
  4. 4Cut dry heads into a bag, rub free, sieve, and store cool and dry.

Storage: 3–5 years dry for most root seed.
