Best Vegetables To Plant In March In Virginia

This section lists the most reliable vegetables for March planting across Virginia. Each one is chosen for its cold tolerance and quick growth before summer heat sets in.

Leafy Greens For Early Harvests

Leafy greens are perfect for March because they germinate in cool soil and grow fast. You can start harvesting some in as little as 30 days.

Spinach

  • Plant seeds directly in garden beds 4-6 weeks before last frost
  • Space rows 12 inches apart, thin seedlings to 6 inches
  • Harvest outer leaves when they reach 3-4 inches tall
  • Best varieties: ‘Bloomsdale’, ‘Space’, ‘Tyee’

Lettuce

  • Choose loose-leaf or romaine types for best results
  • Sow seeds 1/4 inch deep, keep soil moist
  • Thin to 8-10 inches apart for full heads
  • Plant every 2 weeks for continuous harvest

Kale

  • Direct sow or start indoors 4 weeks before transplanting
  • Space plants 18 inches apart in rows 24 inches apart
  • Harvest lower leaves first, leaving center to grow
  • Frost improves sweetness in kale

Root Vegetables For Steady Growth

Root crops thrive in cool, loose soil. They store well and provide fresh produce through late spring.

Carrots

  1. Prepare soil deeply, remove rocks and clods
  2. Sow seeds 1/4 inch deep, 2 inches apart
  3. Keep soil consistently moist until germination (10-14 days)
  4. Thin to 3 inches apart when seedlings are 2 inches tall
  5. Harvest when roots reach finger thickness

Radishes

  • Fastest crop from seed to harvest (25-30 days)
  • Sow seeds 1/2 inch deep, 1 inch apart
  • Thin to 2 inches apart for larger roots
  • Plant every 10 days for steady supply
  • Best varieties: ‘Cherry Belle’, ‘French Breakfast’

Beets

  • Soak seeds overnight to speed germination
  • Plant 1 inch deep, 2 inches apart
  • Thin to 4 inches apart for good root development
  • Harvest greens when 6 inches tall, roots at 2-3 inches
  • Both roots and leaves are edible

Peas And Legumes

Peas love cool weather and stop producing when temperatures rise above 80°F. March planting gives them plenty of time to mature.

Snap Peas

  • Plant seeds 1 inch deep, 2 inches apart
  • Provide trellis or support for climbing varieties
  • Harvest pods when they’re plump and bright green
  • Best varieties: ‘Sugar Snap’, ‘Super Sugar Snap’

Snow Peas

  • Harvest before peas swell inside pods
  • Space plants 3 inches apart in rows 18 inches apart
  • Pick regularly to encourage more production
  • Good for stir-fries and salads

English Peas

  • Shell peas are worth the effort for fresh flavor
  • Plant in full sun with well-drained soil
  • Harvest when pods are full but still bright green
  • Freeze excess for later use

Brassicas For Long Season

These crops take longer to mature but produce heavily in spring. Start them early in March for summer harvests.

Broccoli

  1. Start seeds indoors 6-8 weeks before last frost
  2. Transplant outdoors when seedlings have 4-5 true leaves
  3. Space plants 18 inches apart in rows 24 inches apart
  4. Harvest central head before flowers open
  5. Side shoots will continue producing after main harvest

Cabbage

  • Start indoors or buy transplants from garden centers
  • Space 12-18 inches apart depending on variety
  • Keep soil evenly moist to prevent splitting
  • Harvest when heads feel firm and solid
  • Best varieties: ‘Early Jersey Wakefield’, ‘Golden Acre’

Cauliflower

  • More challenging than broccoli but rewarding
  • Blanch heads by tying outer leaves over them
  • Harvest when heads are compact and white
  • Protect from frost with row covers if needed

Preparing Your Garden Beds For March Planting

Good soil preparation makes all the difference for early crops. Follow these steps to get your beds ready.

Test And Amend Soil

  • Get a soil test kit from your local extension office
  • Aim for pH between 6.0 and 7.0 for most vegetables
  • Add lime if pH is too low, sulfur if too high
  • Mix in 2-3 inches of compost or well-rotted manure
  • Work amendments into top 6-8 inches of soil

Improve Drainage

  • Raised beds work well for Virginia’s clay soils
  • Add organic matter to improve soil structure
  • Avoid walking on wet soil to prevent compaction
  • Consider adding sand or perlite for heavy clay

Warm Soil Before Planting

  1. Cover beds with black plastic 2 weeks before planting
  2. Remove plastic after soil reaches 50°F
  3. Use row covers to protect young plants from cold nights
  4. Water sparingly until plants are established

Frequently Asked Questions

Can I plant tomatoes in March in Virginia?

No, tomatoes are warm-season crops and need soil temperatures above 60°F. Wait until late April or May for transplanting. Start seeds indoors in March for later planting.

What vegetables grow fastest in March?

Radishes, lettuce, and spinach are the fastest. Radishes mature in 25-30 days, while leaf lettuce can be harvested in 30-40 days. These are ideal for impatient gardeners.

Should I use raised beds for March planting?

Raised beds warm up faster in spring and drain better in Virginia’s clay soils. They also make it easier to control soil quality and prevent compaction. Highly recommended for early crops.

How do I protect my March vegetables from frost?

Use row covers, cloches, or cold frames. Water the soil before a frost event. Cover plants in the evening and remove covers in the morning. Plastic sheeting can also work but may trap heat.

Can I plant potatoes in March in Virginia?

Yes, potatoes are cool-season crops. Plant seed pieces 4 inches deep in late March after soil reaches 45°F. Hill soil around stems as they grow to protect tubers from light.

Final Tips For A Successful March Garden

Start small if you’re new to gardening. Focus on a few easy crops like radishes, lettuce, and peas. Expand as you gain experience.

Water deeply but infrequently to encourage deep root growth. Most cool-season crops need about 1 inch of water per week.

Keep a garden journal to track what works and what doesn’t. Note planting dates, weather conditions, and harvest times. This helps you improve each year.

Don’t forget to enjoy the process. March gardening in Virginia is rewarding because you see results quickly. Fresh vegetables from your own garden taste better than anything from the store.
