Mississippi’s humid conditions mean turnips should be planted in early spring or fall to avoid pest pressure. Knowing the best time to plant turnip in mississippi is key to getting a good harvest, whether you want tender greens or big roots.
Turnips are a cool-season crop. They grow fast and can handle light frost. In Mississippi, the weather can be tricky, so timing matters a lot.
This guide will walk you through exactly when to plant turnips in Mississippi. We’ll cover spring and fall planting, plus tips for soil, pests, and harvest.
Best Time To Plant Turnip In Mississippi
The best time to plant turnip in mississippi is in early spring, about 2 to 4 weeks before the last expected frost. For most of Mississippi, that means late February to mid-March.
For a fall crop, plant in late August to early September. This timing helps turnips mature before the first hard frost, which usually hits in November.
Here is a quick breakdown by region in Mississippi:
- Northern Mississippi (like Tupelo, Oxford): Spring planting: March 1–15. Fall planting: August 20–September 5.
- Central Mississippi (like Jackson, Meridian): Spring planting: February 20–March 10. Fall planting: August 25–September 10.
- Southern Mississippi (like Hattiesburg, Gulfport): Spring planting: February 10–March 1. Fall planting: September 1–15.
These dates are general guides. Always check your local frost dates. You can find them from your county extension office.
Why Timing Matters So Much In Mississippi
Mississippi has hot, humid summers. Turnips hate heat. If you plant too late in spring, the roots get woody and bitter. The greens also bolt (go to seed) quickly.
In fall, you want to plant early enough so turnips mature before cold weather stops growth. But not so early that they suffer from late summer heat.
Pests are also a big deal. Flea beetles and root maggots love warm, wet conditions. Planting in cooler weather reduces their damage.
Soil Temperature For Turnip Planting
Turnip seeds germinate best when soil temperature is between 50°F and 75°F. They can sprout in soil as cold as 40°F, but it takes longer.
Use a soil thermometer to check. In spring, soil warms up slower than air. In fall, soil stays warm longer than air.
Here are the ideal soil temps:
- Minimum for germination: 40°F
- Optimal range: 50°F to 75°F
- Maximum for good growth: 85°F
If soil is too hot (above 85°F), seeds may not germinate at all. That’s why fall planting is tricky in early September.
Spring Planting Guide For Mississippi
Spring is a great time for turnips in Mississippi. You get tender greens and sweet roots before summer heat arrives.
When To Start Spring Turnips
Count back from your last frost date. For most of Mississippi, last frost is around March 15 to April 1. Plant seeds 2 to 4 weeks before that.
So, for central Mississippi, plant around February 20 to March 10. For southern areas, you can start as early as February 10.
If you plant too early, a hard freeze can kill seedlings. But a light frost is fine. Turnips actually taste sweeter after a frost.
How To Plant Spring Turnips
- Choose a sunny spot with well-drained soil. Turnips need at least 6 hours of sun daily.
- Prepare the soil. Remove rocks and weeds. Mix in 2 inches of compost or aged manure.
- Sow seeds 1/4 to 1/2 inch deep. Space seeds about 1 inch apart in rows 12 to 18 inches apart.
- Water gently after planting. Keep soil moist but not soggy.
- Thin seedlings when they are 2 inches tall. Leave 3 to 4 inches between plants for roots, or 1 to 2 inches if you only want greens.
Turnip seeds are small. Mix them with sand to make sowing easier. You can also broadcast them and rake lightly.
Spring Turnip Varieties For Mississippi
Some turnip varieties do better in Mississippi’s spring weather. Look for fast-maturing types that resist bolting.
- Purple Top White Globe: Classic variety. Matures in 50-60 days. Good for roots and greens.
- Tokyo Cross: Hybrid that matures in 35-40 days. Very tender roots.
- Hakurei: Salad turnip. Sweet and mild. Matures in 38 days.
- Seven Top: Grown mainly for greens. No big root. Matures in 40 days.
All of these can handle light frost. They also grow fast enough to beat the heat.
Fall Planting Guide For Mississippi
Fall is actually the best season for turnips in Mississippi. Cooler weather means sweeter roots and fewer pests.
When To Start Fall Turnips
Plant fall turnips so they mature 2 to 4 weeks before the first hard frost. First frost in Mississippi ranges from late October (north) to mid-November (south).
Count back from your first frost date using the days to maturity on the seed packet. Add 10 to 14 days for slower growth in cooler fall weather.
Example: Purple Top White Globe takes 55 days. For central Mississippi with first frost around November 1, plant around September 1.
Here are general fall planting windows:
- Northern MS: August 20–September 5
- Central MS: August 25–September 10
- Southern MS: September 1–15
If you plant too early in fall, heat and pests can be problems. If you plant too late, turnips won’t mature before frost.
How To Plant Fall Turnips
- Prepare soil as you did in spring. Add compost and remove debris.
- Sow seeds 1/2 inch deep. Deeper than spring because soil is drier.
- Water well after planting. Fall soil can be dry. Keep it moist until seeds sprout.
- Thin seedlings to 3-4 inches apart for roots.
- Mulch around plants to keep soil cool and moist.
Fall turnips often grow slower than spring ones because days get shorter. But the flavor is usually better.
Fall Turnip Varieties For Mississippi
Most turnip varieties work for fall. But some are especially good for Mississippi’s conditions.
- Purple Top White Globe: Reliable for fall too.
- Alltop: Hybrid for greens. Very productive.
- Gilfeather: Heirloom with sweet roots. Matures in 70-80 days.
- Golden Ball: Yellow-fleshed turnip. Mild flavor. Matures in 60 days.
For fall, you can also plant rutabagas. They take longer (90 days) but are very cold hardy.
Soil Preparation For Turnips In Mississippi
Turnips grow best in loose, fertile soil. Mississippi has many soil types, from sandy loam to heavy clay.
Testing Your Soil
Get a soil test from your county extension office. Turnips prefer a pH between 6.0 and 7.0.
If pH is too low (acidic), add lime. If too high (alkaline), add sulfur. Do this a few months before planting.
Improving Mississippi Clay Soil
Many parts of Mississippi have clay soil. It drains slowly and can be hard for turnip roots.
To fix clay soil:
- Add 2-3 inches of compost or well-rotted manure.
- Work in coarse sand or perlite to improve drainage.
- Use raised beds if drainage is really bad.
Turnip roots need loose soil to grow straight and big. Compacted soil makes them forked or stunted.
Fertilizer For Turnips
Turnips are moderate feeders. They need nitrogen for greens and phosphorus for roots.
Before planting, mix in a balanced fertilizer like 10-10-10 at a rate of 1 pound per 100 square feet.
Side-dress with nitrogen (like blood meal) when plants are 4 inches tall. This boosts leaf growth.
Avoid too much nitrogen late in the season. It makes roots hairy and less sweet.
Watering Turnips In Mississippi
Mississippi gets plenty of rain, but turnips need consistent moisture. Too much or too little water causes problems.
How Much Water
Turnips need about 1 inch of water per week. This includes rainfall.
In spring, rain is usually enough. In fall, you may need to supplement during dry spells.
Water deeply once or twice a week. Shallow watering encourages shallow roots.
Signs Of Water Stress
- Too little water: Leaves wilt, roots become tough and bitter.
- Too much water: Leaves turn yellow, roots rot.
Mulch helps keep soil moisture even. Use straw, leaves, or grass clippings.
Pests And Diseases In Mississippi
Mississippi’s warm, humid climate attracts many pests. Turnips are no exception.
Common Turnip Pests
- Flea beetles: Small jumping bugs that eat holes in leaves. Worst in warm weather.
- Root maggots: Larvae that tunnel into roots. More common in cool, wet soil.
- Aphids: Small insects that suck sap from leaves.
- Cabbage loopers: Green caterpillars that eat leaves.
Planting at the right time helps avoid these pests. Spring planting before it gets warm, and fall planting after pest populations drop.
How To Control Pests
- Use row covers to protect young plants.
- Apply diatomaceous earth around plants for flea beetles.
- Use insecticidal soap for aphids.
- Rotate crops. Don’t plant turnips where other brassicas grew last year.
Common Diseases
- Club root: Causes swollen, deformed roots. Avoid by rotating crops and keeping pH above 6.5.
- Downy mildew: Yellow spots on leaves. Improve air circulation.
- Black rot: Yellow V-shaped spots on leaf edges. Use disease-free seeds.
Good garden hygiene prevents most diseases. Remove plant debris after harvest.
Harvesting Turnips In Mississippi
Turnips are ready to harvest when roots are 2 to 3 inches in diameter. Greens can be harvested earlier.
When To Harvest
Spring turnips: Harvest before temperatures hit 80°F regularly. Usually 50-60 days after planting.
Fall turnips: Harvest after a light frost for sweeter flavor. But before a hard freeze.
Don’t let turnips get too big. Large roots become woody and strong-flavored.
How To Harvest
- Loosen soil around the root with a garden fork.
- Pull the turnip by the greens.
- Cut off greens, leaving 1 inch of stem.
- Wash roots and store in the refrigerator.
Greens can be harvested at any time. Take outer leaves only, leaving inner leaves to grow.
Storing Turnips
Turnip roots store well in a cool, humid place. Keep them in a plastic bag in the refrigerator for up to 2 weeks.
For longer storage, keep them in a root cellar or buried in sand in a cool basement. They can last 2-3 months.
Greens are best eaten fresh. They wilt quickly. Store them in a damp paper towel in the fridge for 3-5 days.
Common Mistakes Planting Turnips In Mississippi
Even experienced gardeners make mistakes. Here are the most common ones with turnips in Mississippi.
Planting Too Late In Spring
This is the biggest error. Turnips planted after mid-March in central Mississippi often bolt or get woody. The heat stresses them.
If you miss the spring window, wait for fall. Don’t try to force a summer crop.
Planting Too Early In Fall
Planting in late August is fine. But planting in mid-August in southern Mississippi can expose turnips to intense heat and pests.
Check the 10-day forecast. If temps are still above 90°F, wait a week.
Overcrowding
Turnip seeds are tiny. It’s easy to sow too thickly. Thin seedlings early. Crowded turnips produce small, misshapen roots.
Ignoring Soil Prep
Turnips need loose soil. If you plant in heavy clay without amending it, roots will be tough and forked.
Take the time to loosen soil to 8-10 inches deep.
Not Rotating Crops
Planting turnips in the same spot year after year invites disease and pests. Rotate with non-brassica crops like beans, corn, or tomatoes.
Wait at least 3 years before planting turnips in the same bed.
Frequently Asked Questions
Can I plant turnips in Mississippi in summer?
No. Summer heat in Mississippi is too intense. Turnips will bolt and roots will be bitter. Stick to spring and fall.
What is the best month to plant turnips in Mississippi?
For spring, March is best for most of the state. For fall, September is ideal. Adjust based on your region.
How late can I plant turnips in Mississippi for fall?
You can plant as late as early October in southern Mississippi, but only for fast-maturing varieties (35-40 days). In northern areas, early September is the cutoff.
Do turnips need full sun in Mississippi?
Yes, turnips need at least 6 hours of direct sun daily. Partial shade reduces root size and flavor.
Can I grow turnips in containers in Mississippi?
Yes. Use a container at least 12 inches deep. Fill with loose potting soil. Water more often since containers dry out fast.
Final Tips For Turnip Success In Mississippi
Planting at the right time is half the battle. The other half is good soil and consistent care.
Keep a garden journal. Note when you planted, what variety, and how the weather was. This helps you refine your timing each year.
Don’t be afraid to experiment. Try different varieties to see what works best in your microclimate.
Remember that turnips are forgiving. Even if you plant a bit late, you’ll likely get some greens and small roots.
With the right timing and a little effort, you can enjoy fresh turnips from your Mississippi garden in both spring and fall.
