Turnips are one of the easiest cool-season vegetables to grow in a Zone 9 garden. They grow quickly, require relatively little space, and provide two different harvests from the same plant: tender roots and nutritious leafy greens.
While many vegetables struggle during the cooler months, turnips thrive when temperatures are mild. This makes them an excellent choice for fall and winter gardening throughout much of Zone 9.
Turnips belong to the cabbage family, along with broccoli, kale, cabbage, and radishes. They grow best when temperatures are approximately 50–65°F. Hot weather and inconsistent watering can cause roots to become tough, woody, or overly pungent.
For most Zone 9 gardeners, fall through winter is the best growing season, although early spring planting is also possible where temperatures remain cool enough.
The secret to growing good turnips is simple: choose the right variety, plant seeds directly into loose soil, maintain consistent moisture, and harvest the roots while they are still tender.
Turnip Selection
There are two main reasons gardeners grow turnips: for their edible roots or for their leafy greens.
Root turnips produce rounded or flattened bulbs that can be roasted, mashed, added to soups, or eaten raw when young and tender.
Turnip greens are harvested for their leaves, which can be cooked similarly to mustard greens, collards, or kale.
Some varieties are better suited to producing large roots, while others are grown primarily for their foliage.
Best Turnip Varieties for Zone 9
Several turnip varieties are worth considering for a Zone 9 vegetable garden.
Purple Top White Globe
One of the most recognizable turnip varieties. It produces rounded white roots with purple shoulders and is a dependable choice for traditional table turnips.
Royal Crown
A turnip cultivar listed in University of California Agriculture and Natural Resources growing recommendations.
Scarlet Queen
A distinctive variety with attractive red skin. It provides an alternative to traditional white-rooted turnips.
De Milan
Known for its flattened roots, this variety offers a different shape from standard globe turnips.
Tokyo
A white-rooted turnip variety suitable for gardeners interested in tender table roots.
Just Right
A root-producing turnip included in Florida growing recommendations. Availability may vary by seed supplier.
Seven Top and Topper
These varieties are grown primarily for their leafy greens rather than large edible roots.
If you’re growing turnips for the first time, Purple Top White Globe is a useful traditional variety to consider. Gardeners who prefer turnip greens may want to grow Seven Top or Topper.
When to Plant Turnips in Zone 9
Turnips are cool-season vegetables, which means planting time is one of the most important factors affecting their quality.
Unlike tomatoes and peppers, turnips generally produce their best roots during mild weather.
In much of Zone 9, fall and winter provide favorable growing conditions. Early spring planting can also work, particularly in locations where temperatures remain cool.
However, Zone 9 includes very different climates. Florida, Texas, Arizona, and California do not share identical planting schedules.
Zone 9 Turnip Planting Calendar
| Season | Direct Sow | Expected Harvest |
|---|---|---|
| Fall and winter | Generally September–February, depending on region | Approximately October–April |
| Early spring | Generally January–March in cooler locations | Approximately February–May |
These are broad planning windows rather than guaranteed planting dates.
In hot desert areas, fall planting may need to wait until October or later. In warmer locations, spring planting opportunities may end early as temperatures rise.
Turnips grow relatively quickly, with roots generally reaching maturity in approximately 30–80 days, depending on the variety and growing conditions.
Because of this short growing period, you can often plant multiple crops during the cool season.
For a more detailed look at seasonal planting opportunities, visit our Zone 9 Fall Planting Guide and Zone 9 Winter Planting Guide.
Location
Turnips prefer full sun and grow best when they receive at least four to six hours of direct sunlight each day.
For the strongest root production, choose a location with good sunlight and well-draining soil.
Turnips grown primarily for their greens can tolerate some partial shade.
Avoid planting turnips in areas where water collects after heavy rainfall. Saturated soil can interfere with root development and increase the risk of disease.
If possible, select a garden bed where other members of the cabbage family have not recently been grown.
Rotating crops helps reduce the buildup of pests and soilborne diseases that affect brassicas.
Soil Preparation
Good soil preparation is especially important when growing turnips for their roots.
Turnips need loose soil that allows the developing roots to expand without obstruction.
Hard, compacted soil can produce misshapen roots and make harvesting more difficult.
Before planting, remove rocks, weeds, and large soil clumps.
Loosen the planting area and incorporate finished compost where needed to improve soil structure.
Turnips prefer fertile, well-drained soil with a pH of approximately 6.0–6.5.
A soil test is the best way to determine whether additional fertilizer or soil amendments are necessary.
Avoid applying excessive nitrogen before planting. Too much nitrogen can encourage leafy growth at the expense of root development.
Raised beds can be useful in gardens with heavy or poorly drained soil.
Sowing Turnips
Turnips are best grown by planting seeds directly into the garden.
Unlike some vegetables, turnips generally do not benefit from being started indoors and transplanted.
Their developing taproots can be disturbed during transplanting, potentially affecting the shape and quality of the harvested roots.
How to Plant Turnip Seeds
- Prepare a loose, smooth seedbed.
- Make shallow planting furrows approximately 1/4–1/2 inch deep.
- Sow the seeds evenly along the row.
- Cover lightly with soil.
- Water gently to settle the soil without washing seeds away.
- Keep the upper soil layer consistently moist during germination.
Turnip seeds commonly germinate in approximately 4–10 days under favorable conditions.
Germination may take longer when soil temperatures are near the lower end of their suitable range.
A practical minimum soil temperature is approximately 45°F, while temperatures around 60–75°F generally support prompt establishment.
Avoid sowing into extremely hot, dry soil because the seedbed may crust or dry before seedlings emerge.
Turnip Plant Spacing
Once seedlings develop, thin them to provide enough room for root growth.
For smaller turnips, spacing of approximately 2–4 inches may be sufficient.
For larger table turnips, allow approximately 4–6 inches between plants.
Rows can generally be spaced approximately 14–24 inches apart in a traditional home garden.
If you’re growing turnips primarily for greens, closer spacing may be practical because large roots are not the main goal.
Do not skip thinning. Overcrowded turnips compete for water, nutrients, and growing space, often resulting in smaller roots.
Growing Turnips
Once turnip seedlings become established, they require relatively simple maintenance.
The most important tasks are keeping the soil evenly moist, controlling weeds, and monitoring plant growth.
Because turnips grow quickly, problems with watering or nutrition can affect the crop before there is much time to correct them.
Watering Turnips
Turnips need consistent moisture to produce tender roots.
As a general starting point, approximately one inch of water per week from rainfall and irrigation may be appropriate, but actual requirements depend on soil conditions and weather.
Sandy soils may dry more quickly, while heavier soils can retain moisture longer.
Avoid allowing the soil to repeatedly dry out and then become saturated.
Inconsistent watering can contribute to poor root quality and overly pungent flavor.
Waterlogged soil can also increase the risk of root diseases.
During cool, rainy weather, irrigation may be unnecessary. During dry winter periods, especially in Arizona and parts of California, supplemental watering may still be important.
Fertilizing Turnips
Turnips benefit from moderate soil fertility, but excessive fertilizer can cause problems.
Before planting, use a soil test to determine whether additional nutrients are needed.
If fertilizer is required, incorporate the recommended nutrients before sowing while keeping concentrated fertilizer away from the seeds.
Once plants reach approximately three to four inches tall, a modest nitrogen side-dressing may be appropriate if soil fertility or plant growth indicates a need.
Water after applying fertilizer.
During root enlargement, maintain even soil moisture and avoid unnecessary late nitrogen applications.
Turnips grown primarily for greens may require somewhat more nitrogen than those grown for their roots.
Turnip Fertilizing Schedule
| Growth Stage | Fertilizer Recommendations |
|---|---|
| Before planting | Soil test, incorporate mature compost, and correct deficiencies |
| At sowing | Apply soil-test-recommended nutrients away from seeds |
| Plants 3–4 inches tall | Side-dress modest nitrogen if needed |
| Root development | Maintain moisture and avoid excessive nitrogen |
Weed Control
Turnips have relatively shallow roots and can suffer when weeds compete for water and nutrients.
Remove weeds while they are small.
Hand-pulling or shallow cultivation is preferable to deep digging near developing turnip roots.
A light layer of suitable mulch may help retain moisture and suppress weeds once seedlings are established.
Common Turnip Pests in Zone 9
Although cool weather can reduce some insect activity, several pests remain active in Zone 9 during fall, winter, and spring.
Inspect plants regularly, particularly while seedlings are small.
Flea Beetles
Flea beetles are small insects that chew tiny, round holes in turnip leaves.
The damage often resembles small shot holes.
Heavy feeding can weaken young seedlings and reduce early growth.
Cabbage Maggots
Cabbage maggot larvae feed on roots and can cause tunneling, poor growth, wilting, and secondary decay.
Problems are more likely under favorable cool, moist conditions.
Aphids
Aphids gather on leaves and tender new growth.
They may cause curling, yellowing, sticky honeydew, and stunted plants.
Inspect the undersides of leaves regularly.
Cabbageworms and Loopers
These green caterpillars chew irregular holes in turnip leaves.
Heavy infestations can remove substantial amounts of foliage.
Look for caterpillars and their dark droppings on damaged leaves.
Harlequin Bugs
Harlequin bugs feed on plant sap and may cause pale blotches, distorted foliage, and wilting.
They can be especially troublesome during warmer periods of fall and spring.
For pest identification and management guidance, consult the UC ANR Turnip Pest Management Guide.
Common Turnip Diseases
Turnips can also develop diseases, particularly when conditions are wet or humid.
Several diseases affecting other cabbage-family vegetables may also affect turnips.
Downy Mildew
Downy mildew can cause yellow patches on leaves and grayish-white growth on leaf undersides.
Cool, humid conditions favor disease development.
Black Rot
Black rot may produce yellow, V-shaped lesions extending inward from leaf edges.
Darkened veins and reduced growth can also occur.
Alternaria Leaf Spot
Alternaria can cause dark circular leaf spots, sometimes with concentric rings and yellow halos.
Clubroot
Clubroot affects the root system and may cause swollen, distorted roots, stunted plants, and wilting.
The disease can persist in infested soil.
Bacterial Soft Rot
Soft rot can cause watery, foul-smelling decay in roots, particularly when tissue is injured or conditions remain excessively wet.
Good drainage, crop rotation, healthy planting material, and appropriate watering practices help reduce many disease risks.
Not every disease is equally common in every Zone 9 region.
Harvesting Turnips
One of the biggest advantages of growing turnips is how quickly they can be harvested.
Depending on the variety and conditions, turnip roots may be ready approximately 30–80 days after planting.
Turnip greens can often be harvested earlier, sometimes around 30 days after sowing.
Harvesting Turnip Roots
For tender table turnips, begin checking roots when they reach approximately two to three inches in diameter.
The ideal harvest size depends on the variety.
Some smaller varieties are especially tender when harvested young, while larger cultivars may be allowed to grow longer.
Turnip shoulders may become visible above the soil as the roots enlarge.
Avoid leaving roots in the garden until they become excessively large.
Overmature turnips can develop a woody texture and stronger flavor.
To harvest, loosen the surrounding soil if necessary and gently pull the roots from the ground.
Harvesting Turnip Greens
Turnip greens can be harvested while the plants are still young.
If you’re growing turnips for both roots and greens, remove only a limited number of outer leaves so the plant retains enough foliage for root development.
For greens-only varieties, the leaves are the primary harvest.
Choose healthy, tender foliage and avoid leaves showing significant pest or disease damage.
Storing Turnips After Harvest
After harvesting, separate the greens from the roots.
This helps reduce moisture loss from the roots and makes storage easier.
Brush off loose soil and refrigerate the roots promptly.
Store the greens separately in the refrigerator and use them relatively soon after harvest.
Tender young turnips are excellent for roasting, soups, stews, and other cooked dishes.
Young roots can also be eaten raw, depending on variety and preference.
Succession Planting Turnips
Because turnips mature quickly, succession planting is an excellent way to maintain a steady harvest.
Instead of planting an entire seed packet at once, sow a smaller amount every two to three weeks while temperatures remain favorable.
This creates multiple harvests rather than one large crop.
Succession planting works particularly well during fall and winter in Zone 9.
However, stop sowing when rising spring temperatures make successful root production unlikely.
For additional information, read our Succession Planting in Zone 9 guide.
Regional Turnip Growing Tips for Zone 9
Zone 9 includes several different growing climates, and planting schedules should reflect those differences.
