March in Zone 7 is that sweet spot—just warm enough to get your hands back in the soil, but still cool enough to plant with confidence. If you’re wondering what to plant in March in Zone 7, you’re in the right place. I’ve spent over a decade tending my backyard garden in central Virginia, and every year, March feels like a quiet promise of the lush months ahead.
Preferences vary, of course. Some gardeners chase bold blooms, others prioritize fragrance or low-maintenance growth. Personally, I love a mix—color that pops, herbs that smell amazing when I brush past them, and veggies that actually make it to the dinner table. This guide is built from real experience, not just textbook advice.
I started gardening seriously after moving to a house with a sunny backyard and terrible clay soil. Fast forward ten years, and that same patch now bursts with life each spring. March was always the turning point—the month where planning met action. And honestly? Getting it right in March sets the tone for the whole season.
In this guide, I’ll share exactly what I plant every March in Zone 7, why these choices work, and how to care for them as the season warms up. Whether you’re planting your first seedling or expanding an existing plot, you’ll walk away with a clear, practical plan.

Cool-Season Veggies That Thrive in March
Lettuce & Spinach: The Salad Stars
I’ve grown lettuce in every corner of my yard—containers, raised beds, even between stepping stones. In March, direct-sowing lettuce and spinach is a no-brainer. The soil is workable, and the cool temps actually improve flavor. Believe me, homegrown spinach tastes nothing like the bagged stuff.
My tip? Sow in succession every two weeks. This way, you’ll have a continuous harvest instead of one big flush. And don’t forget to mulch lightly—it keeps roots cool and prevents mud splashing onto leaves.
Peas: Climbing Toward Sweetness
There’s nothing like snapping a fresh snow pea straight from the vine. I plant ‘Sugar Snap’ and ‘Oregon Sugar Pod’ every March. They germinate well in cool soil and grow quickly once temps rise.
Install your trellis or netting at planting time—don’t wait. Peas grow fast, and they hate having their roots disturbed later. I use recycled bamboo stakes and twine, which also adds a rustic charm to the garden.
Radishes: The Speed Champions
If you want instant gratification, radishes are your answer. ‘Cherry Belle’ and ‘French Breakfast’ go from seed to harvest in under a month. I plant them between slower crops like broccoli to maximize space.
One thing I’ve learned: don’t overwater. Radishes can get woody or split if the soil is too wet. Keep it evenly moist, not soggy.
Brassicas: Broccoli & Cauliflower
These heavy feeders need rich soil, so I amend my beds with compost and a bit of organic fertilizer before planting seedlings in March. I start seeds indoors in February, then transplant when they have 4–6 true leaves.
Watch for cabbage worms—they love these plants as much as we do. I handpick them or use row covers. Honestly, a little vigilance goes a long way.
Flowers That Shine in Early Spring
Pansies: Cheerful and Cold-Hardy
Pansies are my March mood boosters. Their faces seem to smile up at you, even on chilly mornings. I plant them in window boxes, borders, and even hanging baskets.
They tolerate light frost, so don’t worry if temps dip. Deadhead regularly to encourage more blooms. And yes, they’re edible—perfect for garnishing spring salads.
Dianthus: Fragrant and Fuss-Free
I fell in love with dianthus after planting ‘Firewitch’ in a sunny border. The silvery foliage and pink blooms are stunning, and the clove-like scent? Divine.
They prefer well-drained soil and full sun. Once established, they’re drought-tolerant. I’ve had the same clumps come back strong for five years running.
Sweet Alyssum: The Scented Carpet
This low-growing annual spreads gently and fills the air with a honey-sweet fragrance. I plant it along pathways so I catch the scent when I walk by.
It self-seeds readily, so expect volunteers next year. To be fair, I don’t mind—they’re welcome guests.

FAQ
Can I plant tomatoes in March in Zone 7?
Not yet. Wait until late April or early May after the last frost. Tomatoes are heat-lovers and won’t thrive in cool soil.
Should I start seeds indoors or direct-sow in March?
It depends. Fast growers like radishes and lettuce do well direct-sown. Brassicas and flowers like pansies can be transplanted from indoor starts.
What if it snows after I plant?
Don’t panic. Most March plantings in Zone 7 are cold-hardy. A light snow won’t harm established seedlings—just brush off heavy accumulation.
