Georgia’s mild winters allow turnips to grow through much of the cooler months, but knowing the Best Time To Plant Turnip In Georgia can make the difference between a tough, woody crop and a sweet, tender harvest. Turnips thrive in the cool weather of spring and fall, and Georgia’s climate offers two distinct windows for planting. Whether you’re a beginner or a seasoned gardener, timing is everything for a successful turnip patch.
Turnips are a root vegetable that prefers temperatures between 40°F and 75°F. In Georgia, the growing season is long, but the heat of summer can ruin your crop. Plant too early in spring, and a late frost might damage seedlings. Plant too late in fall, and the roots won’t mature before a hard freeze. Let’s break down the exact timing for both seasons.
Best Time To Plant Turnip In Georgia
The ideal planting window for turnips in Georgia is early spring, from mid-February to late March, and again in late summer, from mid-August to early September. These dates vary slightly depending on your region within the state. North Georgia, with its cooler temperatures, can plant a bit earlier in spring and later in fall. South Georgia, where winters are milder, has more flexibility.
For spring planting, aim for soil temperatures around 50°F to 60°F. Turnip seeds germinate best when the soil is cool but not frozen. In most of Georgia, this means planting about 4 to 6 weeks before the last expected frost date. The last frost date ranges from late March in the north to early March in the south.
For fall planting, you want the roots to mature during the cooler days of autumn. Plant about 8 to 10 weeks before the first expected frost. In Georgia, the first frost typically arrives in late October in the north and mid-November in the south. So, late August to early September is your target window.
Spring Planting Guide For Georgia Turnips
Spring turnips are often harvested for their greens, but the roots can be just as tasty if you time it right. The key is to get them in the ground early enough so they mature before the heat of May and June.
- North Georgia: Plant from mid-February to mid-March. Soil warms slowly here, so use a soil thermometer to check.
- Central Georgia: Plant from late February to late March. This region has a longer spring window.
- South Georgia: Plant from early February to early March. Winters are mild, but watch for sudden warm spells.
If you plant too late in spring, the turnips will bolt (go to seed) or become woody and bitter. The roots need consistent moisture and cool temperatures to develop sweetness. Harvest spring turnips before the soil temperature hits 80°F.
Fall Planting Guide For Georgia Turnips
Fall is actually the prefered season for turnips in Georgia. The cooler temperatures and shorter days produce the sweetest roots. Plus, a light frost can actually improve the flavor by converting starches to sugars.
- Timing: Plant 8 to 10 weeks before the first frost. For most of Georgia, this means mid-August to early September.
- Soil prep: Turnips need loose, well-draining soil. Remove rocks and clods to allow roots to grow straight.
- Seeding: Sow seeds 1/4 to 1/2 inch deep, spacing them 1 to 2 inches apart. Thin seedlings to 4 to 6 inches apart once they sprout.
- Watering: Keep the soil consistently moist, especially during germination. Turnips need about 1 inch of water per week.
In south Georgia, you can plant as late as early October for a late fall harvest. In north Georgia, aim for late August to ensure roots mature before a hard freeze.
Regional Variations Across Georgia
Georgia spans USDA hardiness zones 6b in the north to 8b in the south. This affects your planting calendar significantly. Here’s a breakdown by region:
North Georgia (Zones 6b-7a)
Spring: Plant from mid-February to mid-March. Fall: Plant from mid-August to early September. Expect first frost around mid-October to early November.
Central Georgia (Zones 7b-8a)
Spring: Plant from late February to late March. Fall: Plant from late August to mid-September. First frost arrives in late October to early November.
South Georgia (Zones 8b-9a)
Spring: Plant from early February to early March. Fall: Plant from early September to early October. First frost is typically mid-November to early December.
If you live near the coast, the moderating effect of the ocean can extend your growing season. Coastal gardeners can often plant turnips later in fall and earlier in spring than inland gardeners.
Soil Preparation For Turnips
Turnips aren’t picky, but they do best in loose, fertile soil with a pH between 6.0 and 7.5. Heavy clay soil can cause roots to become misshapen or stunted. Here’s how to prepare your bed:
- Test your soil pH. Add lime if it’s below 6.0, or sulfur if it’s above 7.5.
- Work in 2 to 4 inches of compost or well-rotted manure. This improves drainage and adds nutrients.
- Remove any rocks, sticks, or debris that could hinder root growth.
- Rake the soil smooth and create a fine seedbed. Turnip seeds are small and need good contact with the soil.
Avoid using fresh manure, as it can burn the roots and introduce weeds. Also, don’t over-fertilize with nitrogen, which encourages leafy growth at the expense of root development.
Planting Turnip Seeds Step By Step
Turnips are direct-seeded, meaning you plant them right in the garden bed. They don’t transplant well because of their taproot. Follow these steps for best results:
- Choose your variety: For spring, try ‘Purple Top White Globe’ or ‘Tokyo Cross’. For fall, ‘Hakurei’ or ‘White Egg’ are excellent.
- Sow seeds: Plant seeds 1/4 to 1/2 inch deep. Space rows 12 to 18 inches apart.
- Thin seedlings: When seedlings are 2 to 3 inches tall, thin them to 4 to 6 inches apart. You can eat the thinnings as microgreens.
- Mulch: Apply a light layer of straw or grass clippings to retain moisture and suppress weeds.
- Water regularly: Keep the soil moist but not waterlogged. Inconsistent watering can cause roots to crack.
Turnip seeds germinate in 7 to 14 days, depending on soil temperature. In cooler spring soil, it might take a bit longer. Be patient and keep the bed weed-free.
Caring For Turnips During The Season
Once your turnips are up and growing, they need minimal care. Here are the key tasks:
- Watering: Give turnips about 1 inch of water per week. More during dry spells. Drip irrigation is ideal to keep foliage dry and prevent disease.
- Weeding: Keep the bed weed-free, especially when plants are small. Hand-pull weeds to avoid disturbing turnip roots.
- Fertilizing: Side-dress with a balanced fertilizer (10-10-10) when plants are 4 to 6 inches tall. Avoid high-nitrogen formulas.
- Pest control: Watch for flea beetles, aphids, and root maggots. Use row covers early in the season to protect young plants.
Turnips are relatively pest-free, but flea beetles can be a problem in spring. They leave small holes in the leaves. A dusting of diatomaceous earth or neem oil can help control them.
Harvesting Turnips At The Right Time
Turnips are ready to harvest when the roots are 2 to 3 inches in diameter. This usually takes 45 to 60 days from planting, depending on the variety. Don’t let them get too large, or they become tough and woody.
For spring turnips, harvest before the weather gets hot. Once daytime temperatures consistently hit 80°F, the roots will start to decline. For fall turnips, you can leave them in the ground after a light frost. The cold improves their sweetness.
To harvest, gently loosen the soil with a garden fork and pull the turnips by the tops. Cut off the greens, leaving about an inch of stem. Store roots in a cool, humid place like a root cellar or refrigerator. They’ll keep for several weeks.
Common Mistakes To Avoid
Even experienced gardeners make mistakes with turnips. Here are the most common ones:
- Planting too late in spring: This leads to woody, bitter roots. Stick to the early planting window.
- Planting too early in fall: Hot soil can prevent germination. Wait until soil temperatures drop below 80°F.
- Overcrowding: Thin seedlings promptly. Crowded turnips produce small, misshapen roots.
- Inconsistent watering: This causes roots to crack or become tough. Water deeply and regularly.
- Ignoring soil prep: Hard, compacted soil leads to stunted roots. Loosen the bed before planting.
If you follow the correct timing for the Best Time To Plant Turnip In Georgia, you’ll avoid most of these issues. The key is to match your planting date to your local climate.
Turnip Varieties For Georgia Gardens
Not all turnip varieties perform the same in Georgia’s climate. Here are some top picks:
- Purple Top White Globe: A classic variety. Great for both greens and roots. Matures in 50 to 60 days.
- Tokyo Cross: A fast-maturing hybrid. Ready in 35 to 40 days. Perfect for spring planting.
- Hakurei: A sweet, white salad turnip. Best for fall. Matures in 45 days.
- White Egg: An heirloom variety. Smooth, mild roots. Good for both seasons.
- Seven Top: Grown primarily for its greens. Produces no large root but abundant leafy tops.
For Georgia, I recommend starting with ‘Purple Top’ for beginners and ‘Hakurei’ for a gourmet fall harvest. Both are reliable and flavorful.
Extending The Turnip Season
You can stretch your turnip harvest by using succession planting. Sow a new batch of seeds every 2 to 3 weeks during the planting window. This gives you a continuous supply of tender roots and greens.
In south Georgia, you can even plant a third crop in late fall for a winter harvest. Use a cold frame or row cover to protect plants from hard freezes. Turnips can survive temperatures down to 20°F with some protection.
Another trick is to plant turnips in containers. This allows you to move them to a sheltered spot if weather turns extreme. Use a deep pot, at least 12 inches, to accommodate the taproot.
