Virginia’s early spring warmth makes March the prime month for planting beets. The best time to plant beets in Virginia depends on your specific region, but understanding the state’s unique climate zones will help you get a bumper crop every time.
Beets are cool-season vegetables that thrive in Virginia’s transitional climate. They can handle light frosts but struggle in intense heat. This makes timing everything for a successful harvest.
Understanding Virginia’s Growing Zones For Beets
Virginia spans USDA hardiness zones 5b through 8a. The western mountains stay cooler longer, while the eastern coastal plain warms up faster. This affects when you should plant beets in different parts of the state.
Zone 5B And 6A: Western Virginia And Mountains
In the western highlands, including areas like Roanoke and the Shenandoah Valley, spring arrives later. Soil temperatures here don’t reach 50°F until late March or early April. Plant beets from early April through mid-May for a spring crop.
For fall planting in these zones, aim for late July to mid-August. The cooler autumn temperatures help beets develop sweet, tender roots.
Zone 6B And 7A: Central Virginia And Piedmont
Central Virginia, including Richmond and Charlottesville, has a longer growing season. Plant spring beets from mid-March through April. Soil temperatures typically reach 50°F by late March.
Fall planting works well from early August to early September. This gives beets time to mature before the first hard frost.
Zone 7B And 8A: Eastern Virginia And Coastal Plain
The Tidewater region, including Norfolk and Virginia Beach, warms up earliest. Plant spring beets from early March through mid-April. You can even start as early as late February if the soil is workable.
Fall planting runs from mid-August through mid-September. The milder winters allow for later harvests, sometimes into December.
Best Time To Plant Beets In Virginia
The ideal window for spring planting is when soil temperatures reach 50°F to 85°F. Beets germinate best between 50°F and 75°F. Check your soil temperature with a simple thermometer before planting.
For most of Virginia, the sweet spot is mid-March to mid-April for spring crops. For fall crops, plant 8 to 10 weeks before the first expected frost. In Virginia, that means late July to early September depending on your zone.
Spring Planting Calendar By Region
- Western Mountains (Zones 5B-6A): April 1 to May 15
- Central Piedmont (Zones 6B-7A): March 15 to April 30
- Eastern Coastal Plain (Zones 7B-8A): March 1 to April 15
Fall Planting Calendar By Region
- Western Mountains: July 20 to August 15
- Central Piedmont: August 1 to September 1
- Eastern Coastal Plain: August 15 to September 15
How Soil Temperature Affects Beet Germination
Beet seeds are actually clusters of multiple seeds. They germinate slowly in cold soil. At 40°F, it can take 3 weeks or more. At 60°F, seedlings emerge in 5 to 10 days.
Use a soil thermometer to check at 2 inches deep. If the soil is below 50°F, wait. Planting too early leads to poor germination and stunted growth.
Warming Soil Faster In Spring
You can speed up soil warming in Virginia’s cooler regions. Cover your planting bed with black plastic or row covers 2 weeks before planting. This traps heat and raises soil temperature by 5°F to 10°F.
Raised beds also warm faster than ground-level beds. They drain better too, which prevents rot in wet Virginia springs.
Cooling Soil For Fall Planting
For fall crops, soil can be too hot for germination. In August, soil temperatures often exceed 85°F. Beet seeds won’t germinate well above 85°F.
Shade the planting area with a lightweight cloth or plant on the north side of taller crops. Water deeply in the evening to cool the soil naturally.
Preparing Your Soil For Beets In Virginia
Beets need loose, well-drained soil with a pH between 6.0 and 7.0. Virginia’s native soil is often clay-heavy or acidic. Test your soil pH before planting.
Add lime if pH is below 6.0. Work in 2 to 4 inches of compost or aged manure to improve drainage and fertility. Remove rocks and debris that can deform beet roots.
Step-By-Step Soil Preparation
- Test soil pH with a home kit or send a sample to Virginia Tech’s extension service
- Adjust pH with lime or sulfur as needed
- Loosen soil to 12 inches deep using a garden fork or tiller
- Mix in 2 inches of compost and a balanced fertilizer like 10-10-10
- Rake the bed smooth and remove any clods or stones
Fertilizer Needs For Beets
Beets are moderate feeders. Too much nitrogen causes lush tops but small roots. Use a fertilizer low in nitrogen and high in phosphorus and potassium.
Apply 1 pound of 5-10-10 per 100 square feet before planting. Side-dress with the same amount when plants are 4 inches tall.
Planting Beet Seeds Correctly
Sow seeds 1/2 inch deep and 1 to 2 inches apart in rows 12 to 18 inches apart. Beet seeds are multi-germ clusters, so you’ll get 2 to 5 seedlings from each seed.
Thin seedlings to 3 to 4 inches apart when they are 2 inches tall. Use scissors to snip extras at soil level. Pulling can disturb nearby roots.
Succession Planting For Continuous Harvest
Plant a new batch every 2 to 3 weeks during spring and fall. This gives you a steady supply of tender beets instead of one big harvest.
Stop spring planting when daytime temperatures regularly exceed 80°F. Resume fall planting when nights cool to below 70°F.
Watering Requirements
Beets need consistent moisture for even growth. Water 1 inch per week if rain is scarce. Inconsistent watering causes tough, woody roots.
Mulch with straw or shredded leaves to retain moisture and keep soil cool. This also suppresses weeds that compete for nutrients.
Common Beet Varieties For Virginia
Choose varieties suited to Virginia’s climate. Some bolt quickly in heat, while others tolerate cooler conditions.
Top Spring Varieties

Pests And Diseases In Virginia Beet Gardens
Beets face few serious problems in Virginia, but a few pests can appear. Leaf miners are the most common. They create winding tunnels in leaves.
Control leaf miners by covering plants with floating row covers. Remove affected leaves promptly. Beneficial insects like parasitic wasps help naturally.
Common Beet Diseases
- Cercospora leaf spot: Brown spots with purple borders. Avoid overhead watering.
- Root rot: Caused by poor drainage. Plant in raised beds or amend clay soil.
- Scab: Rough patches on roots. Keep soil pH above 6.0.
Natural Pest Control Tips
Companion planting works well. Plant beets near onions, garlic, or mint to repel pests. Avoid planting near pole beans or mustard greens.
Rotate beet crops every 3 years to prevent soil-borne diseases. Don’t plant beets where Swiss chard or spinach grew recently.
Harvesting Beets At The Right Time
Beets are ready to harvest 50 to 70 days after planting. The best size is 1.5 to 3 inches in diameter. Larger beets become woody and less sweet.
Harvest by gently pulling or digging around the root. Twist off the tops, leaving 1 inch of stem to prevent bleeding. Don’t wash beets until ready to use.
Storing Fresh Beets
Store unwashed beets in a plastic bag in the refrigerator. They keep for 2 to 3 months at 32°F to 40°F with high humidity.
For long-term storage, remove tops and store roots in damp sand or sawdust in a cool basement. Check periodically for rot.
Using Beet Greens
Beet greens are edible and nutritious. Harvest outer leaves when 4 to 6 inches long. Leave inner leaves to keep the plant growing.
Cook greens like spinach or Swiss chard. They are rich in vitamins A, C, and K. Use them within a few days of harvest.
Fall Beet Planting Tips For Virginia
Fall beets often taste sweeter because cool temperatures convert starches to sugars. Plant them 8 to 10 weeks before the first frost date.
In Virginia, first frost dates range from October 15 in the mountains to November 15 on the coast. Count backward to find your planting window.
Protecting Fall Beets From Frost
Beets tolerate light frosts but need protection from hard freezes. Cover plants with row covers or straw if temperatures drop below 28°F.
Mulch heavily around the base of plants to insulate roots. You can leave beets in the ground past frost if you cover them well.
Extending The Harvest
In coastal Virginia, you can harvest beets into December. In warmer microclimates, a cold frame or low tunnel extends the season even further.
Plant a final batch in early September for late fall harvest. Choose fast-maturing varieties like Early Wonder or Red Ace.
Common Mistakes When Planting Beets In Virginia
Many gardeners plant too early or too late. Planting in cold, wet soil leads to rot. Planting in hot soil leads to poor germination.
Another mistake is skipping soil preparation. Clay soil in Virginia can stunt beet growth. Always amend with compost and ensure good drainage.
Overcrowding Seedlings
Failing to thin seedlings is a big error. Crowded beets produce small, misshapen roots. Thin to 3 inches apart for best results.
Use the thinned seedlings as microgreens. They are tasty in salads and don’t go to waste.
Ignoring Soil PH
Beets are sensitive to acidic soil. Low pH causes poor root development and nutrient deficiencies. Test and adjust pH before planting.
If you see yellow leaves with green veins, that’s iron chlorosis. It often indicates high pH or poor drainage.
Frequently Asked Questions
Can I plant beets in Virginia in summer?
Summer planting is not recommended because beets bolt and become woody in heat. Focus on spring and fall crops for best results.
How deep should I plant beet seeds in Virginia?
Sow seeds 1/2 inch deep in well-prepared soil. In heavy clay, plant slightly shallower at 1/4 to 1/2 inch.
Do beets need full sun in Virginia?
Beets grow best in full sun, at least 6 hours daily. They tolerate partial shade but produce smaller roots.
What is the best fertilizer for beets in Virginia?
Use a low-nitrogen fertilizer like 5-10-10. Too much nitrogen causes leafy tops and small roots.
How long do beets take to grow in Virginia?
Most varieties mature in 50 to 70 days. Spring crops take longer in cool soil, fall crops mature faster in warm soil.
Final Tips For Success
Start small if you are new to growing beets. Plant a 10-foot row and see how it goes. You can always expand next season.
Keep a garden journal. Note planting dates, weather, and harvest quality. This helps you fine-tune your timing for future years.
Share your harvest with neighbors. Beets are easy to grow and produce abundantly. A little planning goes a long way in Virginia’s diverse climate.
