Before you begin

Grow quickly in cool, loose soil.

Turnips make their best roots and greens when growth never stalls. Cool weather, even moisture, and prompt thinning prevent woody, cracked, overly pungent, or misshapen roots.

Best first decisionChoose a root variety for tender globes, or a greens-focused type when leafy harvests are the priority.

Build your turnip-growing plan

Plan cool sowing, bed space, seed quantity, and repeat harvests.

Small sowings every 7–14 days produce better roots than one oversized row.

Stage 1–3

Direct sow thinly and make room early

Turnips dislike transplanting, and crowded seedlings cannot form smooth, uniform roots.

Prepare loose soil

Choose stone-free, well-drained soil. Loosen deeply for large-rooted types; avoid fresh manure and excess nitrogen.

Use full sun in cool weather.
Provide light afternoon shade as days warm.
Rake a fine, level seedbed.

Sow directly

Plant about 1/2 inch deep in rows, spacing seed roughly 1 inch apart. Keep the surface evenly moist until rapid emergence.

Sow small batchesRepeat every 7–14 days rather than planting a long row all at once.

Thin promptly

Thin spring turnips to 2–4 inches and larger winter types to 3–6 inches, following the variety’s mature diameter.

Snip extras to avoid disturbing roots.
Eat thinnings as microgreens.
Cover early to exclude flea beetles and root flies.

Stage 4

Keep root growth fast and uninterrupted

Even moisture, cool soil, and open spacing produce crisp roots with mild flavor.

Water evenly

Keep the top 6 inches moist without saturation; drought followed by heavy water encourages cracking.

Keep soil cool

Use light mulch after emergence and shift to heat-tolerant crops when warm weather arrives.

Limit nitrogen

Excess nitrogen makes lush tops and small roots. Follow a soil test instead of feeding routinely.

Check roots often

Brush soil from shoulders and harvest as soon as the variety reaches eating size.

Growth checkpoints

Know what to watch for.

Root shoulders and texture are more useful than the calendar alone.

3–7 days

Even emergence

Seedlings form a uniform row without crusted soil.

First true leaves

Final spacing

Each plant has room equal to the expected root diameter.

Root swelling

Visible shoulders

Roots color and expand without cracking or insect scars.

Harvest size

Crisp texture

Roots are firm, juicy, and solid before heat triggers pithiness.

Stage 5

Diagnose turnip problems early

Open a symptom to compare what you see, likely causes, and the next practical check.

Flea beetles and shot holes on turnip leaves

PestFlea beetlesMany tiny round holes in seedling leaves

Cover immediately after sowing with insect netting, seal edges, control brassica weeds, and rotate the bed.

Root maggots tunneling through a turnip root

PestCabbage root maggotsBrown tunnels, scars, and stunted plants

Use exclusion netting before flies lay eggs, rotate crops, remove infested roots, and avoid leaving brassica residues in the bed.

Clubroot swelling and wilt on turnip roots

DiseaseClubrootYellow wilted tops and swollen distorted roots

Improve drainage, avoid moving infested soil, raise pH only according to a soil test, and rotate away from brassicas for several years.

Bolting turnip and hollow pithy root beside a crisp root

Growing stressBolting or pithinessFlower stalks, woody heat, or hollow roots

Plant in cool weather, water evenly, thin promptly, choose a suitable variety, and harvest immediately at mature size.

Stage 6

Pull roots while they are crisp and solid

Spring turnips can pass their peak in days, especially as temperatures rise.

Check: Brush back soil and compare the shoulder diameter with the variety description.
Pull: Harvest after watering or loosen large roots with a fork to prevent breaking.
Store: Remove tops, wash and dry roots, and refrigerate in a perforated bag.

Questions gardeners ask

Turnip growing FAQ

Quick answers for timing, sowing, thinning, watering, containers, roots, bolting, and harvest.

When should turnips be planted?

Sow in early spring and again in late summer for fall. Most spring turnips decline quickly in hot weather.

How deep should turnip seed be planted?

Sow about 1/2 inch deep in a fine, moist seedbed.

How far apart should turnips be?

Thin small round types to 2–4 inches and larger root types to 3–6 inches.

Can turnips be transplanted?

Direct sowing is best because transplanting disturbs the taproot and can produce forked roots.

How often should turnips be watered?

Keep soil evenly moist, usually with about 1 inch weekly adjusted for soil and weather.

Why are my turnips all tops and no roots?

Crowding, excess nitrogen, shade, heat, or harvesting too soon can prevent root swelling.

Why are turnips hot or woody?

Heat, drought, slow growth, and overmaturity intensify flavor and toughen texture.

Why do turnips crack?

Uneven moisture—especially heavy watering after drought—causes rapid swelling and splitting.

Can turnips grow in containers?

Yes. Use at least 6 inches of soil for round types and a deeper container for long roots.

Can turnip greens be eaten?

Yes. Young clean leaves are edible raw or cooked; remove damaged or tough older foliage.

When are turnips ready to harvest?

Check the variety’s expected diameter and pull as soon as roots are full size, firm, and crisp.

How should harvested turnips be stored?

Remove tops, wash and dry roots, and refrigerate in a perforated bag. Winter types store longer than spring turnips.
