Vegetables to Plant in March: Get Your Hands Dirty
Early spring mornings remind me why March holds promise—soil softening, days lengthening, temperatures hovering around 45°F (7°C) to 65°F (18°C). Time to dust off seed packets and awaken the garden beds.
Cool-Weather Greens Are Your Allies
Start with leafy stalwarts—spinach, kale, and Swiss chard. I sprinkle seeds directly into loose, compost-rich soil, enjoying quick germination and early harvests before the heat arrives.
- Spinach: Quick-growing and frost-tolerant, harvest within 4 to 6 weeks.
- Kale: Hardy and nutrient-packed; plant seedlings for an early head start.
- Swiss Chard: Beautifully ornamental yet richly flavored, thrives in cooler temperatures.
Peas and Root Crops: Early Planters Reap Rewards
Peas adore chilly March mornings. I plant sugar snap and snow peas directly into damp soil, ensuring a trellis for climbing varieties.
Radishes and carrots also seize this pre-spring moment. Draw shallow furrows and sow generously—thin them later for an optimal harvest.
- Peas: 50°F (10°C) soil triggers germination; grow vertically to maximize space.
- Radishes: 25 days from seed to salad; ideal for impatient gardeners like me.
- Carrots: Choose shorter varieties for quick, early harvests.
Remember: Carrots love loose, rock-free, sandy soil; amend heavily for straight, sweet roots.
Brighten Your Garden with March-Planted Annual Flowers
March also whispers of vibrant blooms. This month I scatter hardy annual flower seeds directly outdoors, relishing the anticipation of color.
Flowers That Tolerate Early Chill
Hardy annuals shrug off lingering frosts and reward your early effort generously. Favorites include:
- Sweet Peas: Fragrant climbers needing cool ground to germinate best; soak seeds overnight before planting.
- Calendula: Cheery, orange-yellow blossoms; edible petals spice up salads.
- Bachelor’s Buttons: Blue-purple flowers attracting beneficial insects; sow directly outdoors.
Last March, I sprinkled sweet pea seeds along a fence line. By late May, cascades of fragrant blooms perfumed the evening air, rewarding my earlier optimism.
Thinking Ahead: Starting Warm-Season Crops Indoors
March is also ideal for indoor seed-starting. While frost lingers, my windowsills fill with trays of tomatoes, peppers, and eggplants—plants needing head starts to thrive later outdoors.
Start These Favorites Indoors Now
- Tomatoes: Start indoors 6-8 weeks before your final frost date; transplant when soil temperature stabilizes above 55°F (13°C).
- Peppers: Slow-growing seedlings that appreciate extra warmth—heat mats are helpful.
- Eggplants: Similar to peppers, require longer growing time; sow indoors now for abundance later.
Pro tip: Harden off indoor seedlings gradually—expose them to outdoor conditions over a week before transplanting.
Herbs to Start Indoors or Out Right Now
Sneak herbs into your planting plans; March is perfect timing to sow herb seeds indoors or outdoors, depending on your climate zone.
- Cilantro: Prefers cooler weather; direct sow outdoors now.
- Parsley: Takes its sweet time germinating; consider soaking seeds overnight and planting indoors.
- Chives: Hardy perennial; sow seeds directly outdoors or start indoors for quicker growth.
A few springs back, I learned to love cilantro’s fleeting nature—planting seeds every two weeks from March onward ensures a constant supply for salsa and salads.
March gardening can be a messy, hopeful endeavor—muddy boots, chilly fingers—but the payoff always satisfies. Grab seed packets, brave the lingering chill, and plant now for delicious, colorful days ahead.

Frequently Asked Questions About Early Spring Planting
Which vegetables thrive best when sown in early spring?
Vegetables such as peas, spinach, kale, radishes, carrots, and lettuce sprout vigorously in cooler March weather. These crops germinate effectively in soil temperatures ranging from 40°F to 75°F (4°C to 24°C), making them ideal for early sowing.
Are there herbs suitable for planting during this period?
Parsley, chives, dill, and cilantro favor cooler spring conditions and flourish when planted in early March. Sow these herbs directly outdoors, offering full sun or partial shade to encourage vibrant new growth.
What types of flowers can I plant outdoors in early spring?
Early-blooming annuals such as pansies, violas, sweet peas, and calendulas thrive when planted outdoors in early spring. Hardy perennials, including primroses, hellebores, and pulmonaria, also establish themselves well during cooler months.
Should summer-flowering bulbs be planted at this time?
Absolutely. Early spring is optimal for embedding summer bulbs such as lilies, gladioli, dahlias, and freesias. Position bulbs at a depth approximately three times their height to ensure sturdy roots and vibrant summertime flowers.
Can I start planting fruit bushes or trees now?
Yes, early spring provides ideal conditions to establish bare-root fruit bushes and trees, including apples, pears, cherries, raspberries, and blueberries. Planting now enables healthy root systems to form before active spring growth begins.
Is seed-starting indoors necessary for certain plants?
Starting seeds indoors is beneficial, particularly for warm-season plants sensitive to frost, such as tomatoes, peppers, and eggplants. Begin these seeds indoors approximately 6 to 8 weeks before your region’s last expected frost date, then transplant outdoors after temperatures reliably remain above 50°F (10°C).
Deciding what to plant in March sets the tone for the entire gardening year. Seeds sown now offer an honest shot at vibrant harvests, while early-season blooms guarantee color through spring's chill. Select hardy greens, crisp radishes, fragrant herbs, and sturdy peas—plants brave enough to handle lingering frosts and eager enough to flourish swiftly. Planning well in March means savoring bounty sooner and enjoying a garden with authentic character and genuine abundance.
Pro Tips for Maximizing Your March Planting Success
Soil Prep Essentials
- Test soil pH: Most veggies thrive between 6.0–7.0; blueberries prefer a lower 4.5–5.5.
- Integrate compost early: Mix 2–4 inches (5–10 cm) of aged compost into beds two weeks before planting.
- Warm beds faster: Cover soil with clear plastic sheeting one week beforehand for an 8–12°F (4–7°C) temp boost.
Smart Companion Planting Combos
- Carrots + Radishes: Radishes germinate quickly, marking carrot rows clearly for easier thinning.
- Lettuce + Onions: Onion odor repels aphids, protecting lettuce leaves naturally.
- Spinach + Strawberries: Spinach provides ground cover, deterring weeds around strawberry plants.
Seed Starting Tricks
- Presoak large seeds: Beans, peas, and squash soaked overnight germinate 50% faster.
- Increase airflow: Run a fan gently over seedlings daily to stimulate stronger stems and roots.
- Natural fertilizer boost: Water seedlings with diluted seaweed extract weekly to enhance nutrient uptake.
Early Pest Prevention Strategies
- Copper barriers: Prevent slug invasion with copper tape around raised beds or containers.
- Cloches and row covers: Shield young plants from pests and frost, raising temperatures by 5–8°F (2.5–4.5°C).
- Beneficial insects habitat: Attract ladybugs and lacewings by planting dill, fennel, or yarrow nearby.
Boost Nutritional Yield Effectively
- Space smartly: Proper spacing prevents nutrient competition, increasing harvest size by up to 30%.
- Harvest frequently: Regular picking encourages continual yield—leafy greens regenerate faster with weekly harvests.
