Arkansas gardeners should aim for a late winter or early spring beet sowing before the humidity rises. Finding the best time to plant beets in arkansas is key to a successful harvest, as beets thrive in cool weather and struggle in the heat. This guide will walk you through the exact timing, soil preparation, and care needed for a bumper crop of these earthy root vegetables.
Beets are a cool-season crop. They grow best when temperatures are between 50°F and 70°F. In Arkansas, that window is narrow but predictable. Plant too late, and the roots become woody and tough. Plant too early, and a hard freeze can kill young seedlings.
Best Time To Plant Beets In Arkansas
The best time to plant beets in arkansas is actually two distinct windows: one in early spring and one in late summer. For spring planting, aim for mid-February to mid-March in southern Arkansas. In northern parts of the state, wait until early March to early April. For a fall crop, plant from late July to mid-August.
This dual window lets you harvest fresh beets from late spring through early winter. The key is to avoid the peak summer heat, which can ruin beet quality.
Spring Planting Window For Arkansas
Spring planting is the most common choice. Beets need about 50 to 70 days to mature. Count backward from your average last frost date. In Arkansas, the last frost typically occurs between March 20 and April 10, depending on your zone.
For southern Arkansas (zones 7b and 8a), start sowing seeds in mid-February. For central Arkansas (zone 7a), wait until late February or early March. For northern Arkansas (zone 6b), aim for mid-March to early April.
Soil Temperature Matters
Beet seeds germinate best when soil temperature is between 50°F and 85°F. The ideal range is 60°F to 70°F. Use a soil thermometer to check. If the soil is too cold (below 45°F), seeds may rot before sprouting.
You can warm the soil by covering it with black plastic for a week before planting. This can speed up germination by a few days.
Fall Planting Window For Arkansas
Fall planting is often overlooked but can produce sweeter beets. The cooler autumn temperatures concentrate sugars in the roots. For a fall crop, plant 8 to 10 weeks before the first expected frost. In Arkansas, the first frost usually arrives between October 15 and November 10.
For southern Arkansas, sow seeds from late July to mid-August. For central Arkansas, plant from early to mid-August. For northern Arkansas, aim for late July to early August.
Fall Planting Tips
Fall planting can be tricky because of the heat. Beets need consistent moisture to germinate in hot soil. Water deeply after planting and keep the soil damp until seedlings emerge. You can also shade the bed with row cover to reduce soil temperature.
Mulching with straw or grass clippings helps retain moisture and keep roots cool. This is critical for a successful fall crop.
Arkansas Growing Zones And Beet Timing
Arkansas spans USDA zones 6b to 8a. This affects your planting dates. Here is a quick breakdown:
- Zone 6b (northern AR): Spring plant March 15 to April 10. Fall plant July 25 to August 10.
- Zone 7a (central AR): Spring plant March 1 to March 25. Fall plant August 1 to August 15.
- Zone 7b (southern AR): Spring plant February 15 to March 10. Fall plant August 5 to August 20.
- Zone 8a (far southern AR): Spring plant February 10 to March 5. Fall plant August 10 to August 25.
These dates are guidelines. Check your local weather forecast each year. A late cold snap or early heat wave can shift your ideal planting window.
Preparing Your Soil For Beets
Beets need loose, well-drained soil. Heavy clay or rocky soil can cause misshapen roots. Start preparing your bed a few weeks before planting.
Soil Testing And Amendments
Test your soil pH. Beets prefer a pH between 6.0 and 7.0. If your soil is too acidic, add lime. If it is too alkaline, add sulfur. You can buy a simple test kit at a garden center.
Beets need boron for healthy roots. A boron deficiency causes black spots inside the roots. Add a small amount of borax (1 teaspoon per 100 square feet) mixed with water. Do not overdo it, as too much boron is toxic.
Improving Soil Structure
If you have clay soil, mix in compost or aged manure. This improves drainage and adds organic matter. For sandy soil, add compost to help retain moisture. Work the soil to a depth of 8 to 10 inches.
Remove any rocks or large clods. Beets need a smooth, fine seedbed for uniform growth. Rake the bed level before planting.
How To Plant Beets In Arkansas
Planting beets is straightforward. Follow these steps for the best results.
Step 1: Choose Your Beet Variety
Some beet varieties perform better in Arkansas heat. Choose bolt-resistant or heat-tolerant types. Good options include:
- Detroit Dark Red: Classic, reliable, and heat-tolerant.
- Early Wonder: Matures in 50 days, good for spring planting.
- Chioggia: Italian heirloom with red and white rings.
- Golden Beet: Sweeter and less earthy, but slower to germinate.
- Bull’s Blood: Grown for both roots and edible leaves.
For fall planting, choose varieties that mature in 55 days or less. This gives you time before frost.
Step 2: Sow Seeds Correctly
Beet seeds are actually clusters of seeds. Each cluster can produce multiple seedlings. Soak seeds in water for 12 hours before planting to speed germination.
Sow seeds 1/2 inch deep and 1 to 2 inches apart. Space rows 12 to 18 inches apart. Cover lightly with soil and water gently.
Step 3: Thin Seedlings
Once seedlings are 2 to 3 inches tall, thin them to 3 to 4 inches apart. This gives roots room to grow. Use scissors to cut extra seedlings at soil level. Pulling them can disturb nearby roots.
You can eat the thinnings. They are delicious in salads or sauteed.
Step 4: Water Consistently
Beets need about 1 inch of water per week. In dry spells, water deeply twice a week. Inconsistent watering causes woody roots or cracking.
Mulch around plants to retain moisture and suppress weeds. Straw, grass clippings, or shredded leaves work well.
Caring For Your Beet Crop
Beets are low-maintenance but benefit from a few simple practices.
Fertilizing Beets
Beets are heavy feeders. Apply a balanced fertilizer (10-10-10) at planting time. Side-dress with nitrogen when plants are 4 to 6 inches tall. Use fish emulsion or compost tea for organic options.
Avoid too much nitrogen, which can cause lush tops but small roots. Phosphorus and potassium are more important for root development.
Weed Control
Weeds compete with beets for water and nutrients. Keep the bed weed-free, especially in the first few weeks. Hand-pull weeds carefully to avoid disturbing beet roots.
Mulching helps reduce weed growth. Apply a 2-inch layer of organic mulch around plants.
Pest And Disease Management
Common beet pests in Arkansas include leaf miners, aphids, and flea beetles. Use row covers to protect young plants. Spray with neem oil or insecticidal soap if needed.
Diseases like cercospora leaf spot and root rot can occur. Avoid overhead watering to reduce leaf wetness. Rotate crops each year to prevent soil-borne diseases.
Harvesting Beets In Arkansas
Beets are ready to harvest when roots are 1 to 3 inches in diameter. This usually happens 50 to 70 days after planting. Do not let them get too large, or they become woody.
When To Harvest
Check the size by gently brushing away soil at the base of the leaves. Harvest when roots are about the size of a golf ball. For larger beets, wait until they reach 2 to 3 inches, but no bigger.
In Arkansas, spring-planted beets are ready from May to June. Fall-planted beets are ready from October to November. You can leave beets in the ground after frost, but harvest before a hard freeze.
How To Harvest
Loosen the soil around the beet with a garden fork. Grasp the leaves near the base and pull gently. If the root is stuck, dig around it to avoid breaking it.
Cut off the leaves, leaving 1 inch of stem. This prevents the roots from bleeding moisture. Store beets in a plastic bag in the refrigerator for up to 2 weeks.
Common Mistakes When Planting Beets In Arkansas
Avoid these pitfalls for a better harvest.
- Planting too late in spring: Beets bolt or become woody in heat.
- Planting too early in fall: Seeds may rot in hot soil.
- Not thinning seedlings: Crowded roots are small and misshapen.
- Inconsistent watering: Causes cracking or tough roots.
- Ignoring soil pH: Beets are sensitive to acidic soil.
- Over-fertilizing with nitrogen: Lots of leaves, small roots.
By avoiding these mistakes, you can grow beets that are sweet, tender, and full of flavor.
