Data updated: August 2026Sources & method · Corrections
March is the great thaw in Massachusetts — Red-winged Blackbirds and woodcock return to the marshes, the first wildflowers push through, the maple sap runs hard in the Berkshires, and the whole state tilts from winter into spring.
Week by week in March
February 26 – March 4
- Red-winged blackbirds and common grackles return to the marshes, males singing from the cattails — a classic first sign of New England spring.
- Pussy willows push out soft gray catkins along stream edges, and red maple buds swell toward bloom.
- On a rare warm, sunny afternoon, an overwintering mourning cloak might stir in the mildest valley or coastal woods — though it's still very early.
March 5–11
- At dusk in damp old fields, American woodcock begin their spiraling 'peent'-and-twitter sky dance at sites like Broadmoor and the Sudbury meadows.
- Skunk cabbage spreads its mottled hoods in the swamps, and snowdrops and the first crocus open on warm south-facing slopes.
- The winter stars sink westward in the evening while Leo and the Big Dipper climb high in the east, ushering in the spring sky.
March 12–18
- Waterfowl migration peaks on thawing ponds — Wood Ducks, Ring-necked Ducks, and Hooded Mergansers return, and migrating geese stream overhead.
- Red maple flowers open on bare twigs across the swamps and lowlands, painting whole hillsides a faint reddish haze — the first real color of the year.
- As soon as soil is workable in the warmer east, direct-sow peas, spinach, and radishes and plant onion sets.
March 19–25
- Turkey vultures and the first ospreys reappear, eastern phoebes return to bridges and eaves, and tree swallows arrive over the marshes.
- The first spring ephemerals stir in rich woods — hepatica and bloodroot — and the fragrant Mayflower (trailing arbutus) prepares to open in the pine woods.
- The spring equinox near the 20th brings day and night into balance as the dark observing window steadily shrinks.
March 26 – April 1
- Piping plovers settle onto the southern beaches and ospreys reclaim their nest platforms along the Cape and South Shore.
- On warm afternoons, mourning cloaks and eastern commas glide along sunny woodland edges, feeding on running maple sap — the first butterflies of the year.
- Sugar maple sap runs hard in the hill towns, and the catkins of alders and birches lengthen and shed pollen.
Birds This Month
March brings the first big pulse of returning migrants to Massachusetts. Red-winged Blackbirds and Common Grackles flood back into the marshes, males singing from the cattails, and American Robins and Eastern Bluebirds gather in noisy flocks. At dusk in damp old fields and wet thickets, American Woodcock begin their spiraling 'peent'-and-twitter sky dance — a classic early-spring spectacle at sites like Broadmoor and the Sudbury River meadows.
Waterfowl migration peaks on thawing ponds and reservoirs: Wood Ducks, Ring-necked Ducks, Hooded and Common Mergansers, Northern Pintail, and Green-winged Teal, while Canada Geese pair off and thousands of migrating geese stream overhead. Turkey Vultures and the first Ospreys reappear late in the month, and Eastern Phoebes return to bridges and eaves. On the coast, wintering sea ducks at Cape Ann begin thinning out, and Piping Plovers arrive on the southern beaches at month's end. Bald Eagles are incubating at the Quabbin.
What's Blooming
March is when Massachusetts wildflowers finally begin. In wet woods and swamp edges, skunk cabbage spreads its mottled hoods and unfurls the first green leaves, the earliest native bloom. On warm south-facing slopes and rich woods, the very first spring ephemerals stir late in the month — the lavender of round-lobed hepatica, the white of bloodroot wrapped in its leaf, and the dangling green bells of spring beauty foliage pushing up.
In gardens and along walks, the early bulbs put on the first real color: snowdrops, winter aconite, crocus, and glory-of-the-snow open through the month, and witch hazel finishes its yellow bloom. The evergreen trailing arbutus (the Mayflower, the state flower) prepares to open its fragrant pink-white flowers in the acidic pine woods at the warm end of the month. The pace is fastest in the mild coastal lowlands and slowest up in the cold Berkshire hill towns, but everywhere the botanical year is now visibly underway.
Garden This Month
March is when Massachusetts gardens come back to life, though the pace varies sharply by region. As soon as the soil thaws and dries enough to work without clumping, direct-sow the hardiest crops — peas, spinach, radishes, lettuce, arugula, and carrots — and plant onion sets, potatoes, and bare-root asparagus and fruit trees in the warmer eastern and coastal zones. Finish dormant pruning of apples, pears, and grapes before bud-break, and cut back last year's perennial stalks and ornamental grasses.
Indoors, the seed-starting bench is in full swing: keep growing onions and leeks, start peppers, eggplant, tomatoes, and brassicas under lights, and pot up slow herbs. Rake winter debris and gently pull mulch back from emerging bulbs and perennials, but keep frost protection handy — hard freezes are routine all month. The Berkshires remain firmly in late winter while the Cape races ahead, so let your local soil and frost dates set the calendar.
Zone 5b (Berkshires & western hills): still thawing and frost-prone, with snow possible all month — start cool-season seedlings indoors, finish dormant fruit-tree pruning, and wait on outdoor sowing until the soil dries and warms in April.
Zone 6a (central Massachusetts): the ground is opening up — as soon as soil is workable, direct-sow peas, spinach, and radishes, plant onion sets, and prune fruit trees before bud-break.
Zone 7a (Cape Cod & coast): the warmest, earliest zone — direct-sow peas, spinach, lettuce, and radishes, set out cold-hardy transplants like brassicas, and uncover overwintered greens as the season jumps ahead of the rest of the state.
What's at the Farmers Market
March markets in Massachusetts are dominated by maple syrup, as the sugarhouses of the Berkshires, hill towns, and central uplands hit their peak boil. This is the freshest, most abundant syrup of the year, and many sugarhouses open for tours and tastings — look for the new season's syrup graded from delicate golden to robust dark at markets and farm stands statewide.
Alongside the syrup, the stands still carry winter storage crops — apples, potatoes, onions, carrots, beets, parsnips, cabbage, and winter squash — running lower now as the season turns. Greenhouse spinach, kale, microgreens, and salad mix stay fresh and plentiful, and eggs, cheese, and honey are reliable. Choose maple syrup by color grade for the flavor strength you prefer, and store it sealed and cool, refrigerating after opening to prevent mold. March is the sweetest month of the New England market year.

Night Sky This Month
March marks the turn from the winter sky to the spring sky over Massachusetts, with the spring equinox near month's end bringing day and night into balance and shrinking the long observing window. The brilliant winter stars — Orion, Sirius, the Pleiades, and the Winter Hexagon — still dominate the early-evening southwest but sink lower each night.
Rising in the east is the spring sky: Leo the lion stands high with bright Regulus at the base of its 'sickle,' and the Big Dipper climbs to ride high overhead, its handle ready to 'arc to Arcturus' later in the night. The faint Beehive Cluster in Cancer is a good binocular target. There is no major meteor shower this month, so March rewards constellation-learning on the milder, lengthening evenings. A dark Berkshire or Quabbin-area site still offers excellent views before the trees leaf out.

Butterflies & Pollinators
March brings the first butterflies of the year to Massachusetts, though only on the warmest, sunniest afternoons. The overwintering adults wake and take flight: the deep maroon, cream-edged mourning cloak is usually the first species seen, gliding along sunny woodland edges and forest roads, often while snow still lingers in the shadows. The eastern comma and question mark, with their ragged orange wings, may join it, sunning on bark and tree trunks.
These early fliers don't need flowers — they feed on tree sap, especially at the broken ends of maples flowing during the thaw, and on any early nectar. Sightings are most likely in the warmer eastern lowlands and river valleys, and far less likely up in the cold Berkshire hill towns, where winter holds on longer. No new generations are flying yet; these are last year's survivors, emerging from hibernation. Their appearance is the first true sign that the Massachusetts butterfly season has begun.

Trees This Month
March is when the Massachusetts forest stirs awake. The headline is the bloom of red maple, whose tiny red flowers open on bare twigs across the swamps and lowlands, painting whole hillsides a faint reddish haze — the first real color of the tree year. Silver maple and the maples flower early too, and the catkins of alders, birches, aspens, and hazelnuts lengthen and release pollen on warm days.
The sugar maple sap run peaks early in the month in the hill towns, the foundation of the syrup harvest, and as the days warm and lengthen the buds of many trees begin to swell. Pussy willows push out their soft gray catkins along stream edges and wet ground, a classic harbinger of New England spring. The evergreens — white pine, hemlock, and coastal pitch pine — still hold the deepest green, but the deciduous forest is now visibly waking, weeks from full leaf-out but no longer dormant.
