March planting in Virginia requires flowers that can handle cool nights and occasional frost. The key is selecting varieties that germinate in cold soil and bloom early. Here are the top picks, organized by type.

Hardy Annuals For March Planting

Hardy annuals are your best bet for March. They tolerate frost and bloom quickly. Plant them directly in the ground or in containers.

Pansies – These classic cool-weather flowers thrive in 40-60°F soil. They come in many colors and bloom until late spring. Plant them 6-8 inches apart in well-drained soil.
Snapdragons – They handle light frosts well. Sow seeds directly or use transplants. They grow tall and add vertical interest to beds.
Calendula – Also called pot marigold, this flower is easy to grow from seed. It blooms in cool weather and self-seeds for next year.
Sweet Alyssum – Low-growing and fragrant, it works well as a border or ground cover. It tolerates light frost and blooms continuously.
Larkspur – A true cool-season annual that needs cold soil to germinate. Sow seeds in March for June blooms. It reseeds readily.

Perennials That Can Go In Early

Perennials planted in March have time to establish roots before summer heat. Choose varieties that are hardy in Virginia’s zones 6-7.

Lenten Rose – Also called Hellebore, it blooms in late winter. Plant it in partial shade. It is deer-resistant and long-lived.
Bleeding Heart – This shade-loving perennial emerges early. It flowers in April and May. Plant bare-root or container plants now.
Columbine – Native to Virginia, it thrives in cool soil. Sow seeds directly or plant transplants. It attracts hummingbirds.
Dianthus – Also called pinks, these flowers tolerate cold. They bloom in spring and often rebloom in fall. Plant in full sun.
Coreopsis – A tough native perennial that starts well from seed. It blooms from late spring through summer. It is drought-tolerant once established.

Bulbs And Tubers For March

March is the last chance to plant spring-blooming bulbs that need cold stratification. It is also time to start summer bulbs indoors.

Daffodils – If you missed fall planting, plant potted daffodils now. They will bloom this spring. Choose large, firm bulbs.
Tulips – Similar to daffodils, potted tulips can go in now. They need full sun and well-drained soil.
Lilies – Plant lily bulbs in March for summer blooms. They prefer slightly acidic soil and good drainage.
Gladiolus – Start corms indoors in pots. Transplant after last frost. They bloom in late summer.
Dahlias – Start tubers indoors in March. Plant them outside in May. They need warm soil to thrive.

Native Virginia Flowers For March

Native plants are adapted to local conditions and support pollinators. They require less water and fertilizer.

Virginia Bluebells – These ephemeral wildflowers bloom in early spring. Plant them in moist, shady areas. They go dormant by summer.
Wild Columbine – A native that attracts hummingbirds. It grows in rocky, well-drained soil. Plant seeds or transplants now.
Butterfly Weed – A type of milkweed that hosts monarch butterflies. It needs full sun and sandy soil. Sow seeds directly in March.
Black-Eyed Susan – This tough native blooms from June to frost. It self-seeds and tolerates poor soil. Plant seeds or transplants.
Goldenrod – Often blamed for allergies (but it is ragweed that causes them), goldenrod blooms in late summer. It is great for pollinators.

How To Prepare Your Soil For March Planting

Good soil prep makes a big difference. Virginia soil can be clay-heavy or sandy, depending on your region. Here is a step-by-step guide.

Test your soil pH – Most flowers prefer pH 6.0-7.0. Test kits are cheap at garden centers. Add lime if pH is too low, sulfur if too high.
Remove weeds and debris – Pull out winter weeds and old plant matter. This prevents disease and pests.
Amend with compost – Spread 2-3 inches of organic compost over the bed. Mix it into the top 6 inches of soil. This improves drainage and nutrients.
Add slow-release fertilizer – Use a balanced 10-10-10 formula. Follow package rates. Too much nitrogen causes leafy growth but few flowers.
Rake smooth – Level the soil surface. Remove rocks and clumps. This makes planting easier.

Dealing With Clay Soil

Clay soil is common in many parts of Virginia. It drains slowly and can be hard for roots. Here is how to improve it.

Add coarse sand or perlite to improve drainage.
Mix in aged bark or leaf mold to lighten the texture.
Raise beds if drainage is very poor. Use 6-8 inch tall beds.
Avoid working clay when it is wet—it compacts easily.

Dealing With Sandy Soil

Sandy soil drains fast but lacks nutrients. It warms up quickly in spring. Improve it like this.

Add lots of organic matter like compost or peat moss.
Use a slow-release fertilizer because nutrients wash out quickly.
Mulch heavily to retain moisture and cool roots.
Water more frequently, especially in dry spells.

Step-By-Step Planting Guide For March

Follow these steps for successful March planting in Virginia. Adjust based on your specific microclimate.

Check your frost date – In Virginia, last frost ranges from late March in coastal areas to mid-April in the mountains. Know your zone.
Choose the right flowers – Stick to the list above. Avoid tender annuals like marigolds or zinnias until May.
Prepare the planting area – Follow the soil prep steps above. Make sure the bed is weed-free.
Sow seeds or plant transplants – Follow seed packet depth and spacing. Water gently after planting.
Protect from frost – Cover new plants with row cover or old sheets if a hard freeze is forecast. Remove covers in the morning.
Water wisely – March soil is often moist, so do not overwater. Check soil 1 inch deep—if dry, water. If wet, wait.
Mulch lightly – Use 1-2 inches of shredded bark or straw. This keeps soil temperature stable and prevents weeds.

Starting Seeds Indoors

Some flowers need a head start indoors. March is the time to begin seeds for warm-season flowers. Here is how.

Use seed-starting mix, not garden soil. It is lighter and sterile.
Plant seeds in trays or pots with drainage holes.
Keep soil moist but not soggy. Cover trays with plastic wrap until seeds germinate.
Place under grow lights or in a bright window. Seedlings need 14-16 hours of light daily.
Harden off plants before moving them outside. Start with 1 hour outdoors, increase daily over a week.

Regional Tips For Virginia Gardeners

Virginia spans several climate zones. What works in Norfolk may not work in Roanoke. Here are tips for different regions.

Coastal Virginia (Zones 7B-8a)

Coastal areas have milder winters and earlier springs. March soil warms faster here.

Plant pansies, snapdragons, and sweet alyssum in early March.
Start warm-season seeds indoors by mid-March.
Watch for salt spray if near the coast. Rinse plants after storms.
Use raised beds if soil is sandy or salty.

Piedmont Region (Zones 7A-7b)

The Piedmont has moderate winters and clay-heavy soil. March is a good planting month.

Amend clay soil with compost and gypsum.
Plant perennials like columbine and dianthus in mid-March.
Protect new plants from late frosts in early April.
Mulch to keep soil cool and moist.

Mountain And Western Virginia (Zones 6A-6b)

Higher elevations have colder soil and later springs. Wait until late March or early April.

Plant hardy annuals like pansies and larkspur in late March.
Use row covers to protect from frost.
Start seeds indoors for warm-season flowers.
Choose native plants that are adapted to cold.

Common Mistakes To Avoid In March

Even experienced gardeners make mistakes. Here are the most common ones in March.

Planting too early – Tender flowers like impatiens will die in a frost. Wait until May for these.
Overwatering – Cool soil holds moisture longer. Check before watering. Wet roots rot easily.
Ignoring soil temperature – Use a soil thermometer. Most seeds need at least 45°F to germinate.
Skipping soil prep – Poor soil leads to weak plants. Always amend and test.
Not hardening off transplants – Sudden outdoor exposure shocks plants. Gradual acclimation is key.
Forgetting to label – It is easy to forget what you planted where. Use markers or a garden journal.

Flowers To Avoid In March

Some flowers should wait until the soil warms up. Do not plant these in March.

Marigolds – They need warm soil and will rot in cold.
Zinnias – Frost kills them. Wait until May.
Petunias – They are tender and need warm nights.
Cosmos – They germinate best in warm soil. Plant in April or May.
Sunflowers – They grow fast but need warm soil. Wait until April.
Morning Glories – They are sensitive to cold. Plant after last frost.

Maintaining Your March-Planted Flowers

Once planted, your flowers need care through spring. Here is a simple maintenance routine.

Water deeply but less often – This encourages deep roots. Aim for 1 inch of water per week.
Deadhead spent blooms – Remove faded flowers to encourage more blooms. This works for pansies, snapdragons, and dianthus.
Fertilize lightly – Use a balanced liquid fertilizer every 2-3 weeks. Do not overfeed.
Watch for pests – Aphids and slugs appear in cool weather. Hand-pick or use insecticidal soap.
Mulch as needed – Refresh mulch to keep soil cool and moist. Keep it away from plant stems.
Stake tall flowers – Snapdragons and larkspur may need support. Use bamboo stakes or cages.

Dealing With Late Frosts

Virginia weather is unpredictable. A late frost can damage new plants. Here is how to protect them.

Cover plants with frost cloth, old sheets, or plastic sheeting. Remove covers in the morning.
Water the soil before a frost. Wet soil holds heat better than dry soil.
Mulch heavily around plant bases to insulate roots.
Use cloches or milk jugs cut in half to cover individual plants.
Bring potted plants indoors or into a garage overnight.
