Arkansas Nature Guide: March 2026
March is when spring truly arrives in Arkansas — the redbuds wash the roadsides magenta, the Ozark woodland wildflowers carpet the hollows, and the first wave of returning migrants reaches the state. It is a fast-moving, exhilarating month as the Natural State leaps from late winter into full bloom.
What to look for this week
- Vast flights of mallards, pintail, and snow geese pack the flooded rice fields and refuges around Stuttgart at the height of the Delta duck season.
- The Quadrantid meteor shower peaks around January 3 in a short, sharp burst; look toward the northeast after midnight from a dark Ozark sky.
- The bare bottomland sycamores glow with their white, peeling upper bark against the gray winter woods of the Cache River.
- A planning and pruning month statewide; order seeds early and prune dormant fruit trees and muscadines on mild days.
Birds This Month
March is a month of departures and arrivals in Arkansas. The great wintering flocks of snow geese, greater white-fronted geese, and ducks pull out of the Delta and stream north, and by mid-month the rice fields around Stuttgart are far quieter than in January. As they leave, the first spring migrants pour in: purple martins fill their gourds and houses statewide, tree swallows and barn swallows return over the water, and the first ruby-throated hummingbirds reach the warm south late in the month.
The breeding season opens. Resident Eastern bluebirds, Carolina chickadees, and Carolina wrens are nesting, the state bird, the Northern mockingbird, sings around the clock, and the early returning Louisiana waterthrush sets up along clear Ozark streams — one of the first warblers back. Listen for the brown thrasher and the returning blue-gray gnatcatcher, and for woodcock still displaying at dusk early in the month.
The grand prize arrives at the western edge: the Scissor-tailed Flycatcher, Arkansas's most elegant summer bird, returns to the prairies and roadsides of the Arkansas Valley and the west, perching on fence wires with its long forked tail streaming. Bald eagles have young in the nest by now around the big lakes.
This month's tip: watch your local purple martin colony and your hummingbird feeders for the season's first arrivals, and take a drive through the Arkansas Valley late in the month to catch the first scissor-tailed flycatchers back on the wires — a sure sign Arkansas summer is on its way.
What's Blooming
March is the opening of Arkansas's wildflower spectacle, and the Ozark and Ouachita woods explode with early ephemerals. The pink-striped spring beauty carpets whole hillsides, joined by drifts of white bloodroot, nodding yellow trout lily, lacy Dutchman's breeches, blue wild blue phlox, and the deep-maroon Ozark wakerobin — the Ozark trillium that is one of the Highlands' signature spring flowers.
The woodland floor fills fast. Mayapple unfurls its umbrellas, rue anemone and false rue anemone dance in the breeze, wild ginger hides its maroon flowers at ground level, and bellwort and jack-in-the-pulpit rise in the damp hollows. In the Delta and along roadsides, fields turn purple with henbit and dead-nettle, and the first wild plum thickets foam white along the fencerows.
Where to see it: the rich hollows of the Ozark and Ouachita National Forests, the Buffalo National River trails, and limestone slopes near streams are world-class now — go mid-to-late March for the fullest show and walk early when the light is soft. The bloom runs earliest in the south and lowlands and climbs into the higher Ozarks as the month ends; the trillium and trout lily are at their most luminous on a still, damp morning.
Garden This Month
March is a busy, pivotal month in the Arkansas garden, the great transition from cool season toward warm. Early in the month, finish planting the cool-lovers across the state — English peas, potatoes, onions, spinach, lettuce, carrots, beets, and radishes — and set out hardy transplants of cabbage, broccoli, cauliflower, and collards. Mid-March is the classic window to get potatoes and peas in across central Arkansas.
The year then pivots on the average last frost, which falls in late March in the warm south, early-to-mid April across central Arkansas, and mid-to-late April in the upper Ozarks. Harden off the tomato, pepper, and eggplant seedlings you started in February, but resist setting them out until your local frost date passes and the soil genuinely warms — cold soil makes them sulk and rot. In the warm south you can begin direct-sowing beans, squash, and cucumbers at month's end. Keep row cover handy, because Arkansas's notorious late cold snaps can still strike. March is also prime time to plant blackberry canes, asparagus crowns, and pollinator perennials while spring rains keep the soil moist.
Zone 6b (upper Ozarks, Fayetteville and the northwest): the cool-season garden goes in now. Plant peas, onion sets, potatoes, spinach, lettuce, and radishes, and set out hardy cabbage, broccoli, and collard transplants. The last frost here runs mid-to-late April, so keep tomatoes and peppers indoors a while longer.
Zone 7a (Ozark and Ouachita valleys, Little Rock area): plant the full cool-season garden — peas, potatoes, onions, carrots, beets, lettuce, and cole crops. Toward month's end the soil is warming; the average last frost falls in early-to-mid April, so harden off tomatoes and peppers but hold them a couple more weeks under cover.
Zone 7b (south Arkansas and the lower Delta): the warm season begins. After the late-March last frost in the warmest spots, you can begin setting out tomato and pepper transplants and direct-sowing beans and squash as the soil warms, while finishing the cool-season sowings early in the month.
What's at the Farmers Market
March markets in Arkansas finally start to green up after the long storage season. The first true spring crops appear — tender spinach, leaf lettuce, arugula, and spring mix from high tunnels and early fields, along with the first radishes, green onions, and green garlic. The cold-sweetened kale, collards, and mustard greens are still abundant and at their best.
The storage crops carry on alongside — sweet potatoes, the last winter squash, and stored onions and pecans — but the energy is shifting toward fresh. This is the big month for vegetable and flower seedlings, as growers sell tomato, pepper, and herb starts and bedding plants for the home garden. Local honey, milled Delta rice, and pasture eggs round out the tables, and toward month's end the first cuttings of asparagus may appear from the earliest beds.
For selection and storage: choose spring greens that are crisp and unwilted, store them dry in the crisper, and use them within a few days. Trim radish and green-onion tops if storing more than a day or two. When buying seedlings, pick stocky, deep-green plants over tall, leggy ones, and harden them off outdoors gradually before planting them into the still-cool spring soil.
Night Sky This Month
March brings the spring equinox and a transitional Arkansas sky, with the air often clear between fronts before the humid haze of summer arrives. The dark Buffalo National River International Dark Sky Park, the high overlook at Mount Magazine State Park, and the Ouachita National Forest all offer superb viewing, and many Arkansas state parks host spring stargazing programs as the weather warms.
The winter giants are sinking westward — Orion and brilliant Sirius set earlier each night — while the spring constellations take over. Leo the Lion climbs high in the east, his backward-question-mark 'sickle' easy to trace, and the Big Dipper rides high in the north. Follow the curve of the Dipper's handle to arc toward orange Arcturus, rising in the late evening. The faint Beehive Cluster in Cancer is well placed between Gemini and Leo for binoculars under a dark Ozark sky.
March has no major meteor shower, but the lengthening dark hours and crisp post-frontal nights make it fine for galaxy hunting — the galaxies of Leo and the Virgo region begin to climb into view for telescope owners. Because the planets shift position each year, check the printable Arkansas night-sky guide for this year's specific planet visibility and the best clear, moonless viewing nights from your latitude.
Butterflies & Pollinators
March is when Arkansas's butterfly season truly opens, especially from the middle of the month on as the redbuds and woodland wildflowers bloom. The overwintering adults are joined now by the first fresh spring butterflies emerging from chrysalis, and on a warm, sunny day the woods and gardens come alive.
The early fliers are a delight. The dainty white falcate orangetip patrols the rich Ozark woods, its males tipped with orange; the powder-blue spring azure drifts through blooming thickets; and the striped zebra swallowtail, tied entirely to native pawpaw, appears wherever pawpaw thickets grow in the bottomlands. The big black-and-yellow eastern tiger swallowtail and the iridescent pipevine swallowtail begin sailing through the redbud and plum bloom, and cabbage whites, pearl crescents, and eastern tailed-blues appear over fields. The first monarchs moving north may reach Arkansas late in the month.
To support them now: make sure your native milkweed is up and protected for the returning monarchs, and value the early bloomers — redbud, wild plum, spring phlox, and woodland wildflowers are the crucial first nectar. A stand of native pawpaw in your woods or garden is the key to hosting the striking zebra swallowtail, found almost nowhere without it.
Trees This Month
March is the explosive month of the Arkansas tree year. The eastern redbud leads the show, lighting up roadsides, woodland edges, and the Ozark and Ouachita understory with clouds of magenta-pink flowers blooming directly on bare branches — the defining color of an early Arkansas spring. The native wild plum foams white along fencerows, and the serviceberry adds early white bloom in the Highland woods.
The whole forest begins to leaf and flower. The red maples finish flowering and hang their red samaras, the oaks, hickories, and elms drape pollen-bearing catkins and unfurl soft new leaves, and in south Arkansas's pine country the loblolly and shortleaf pines dust everything with yellow pollen on the windy days. In the bottomlands, the pawpaw opens its odd maroon bell flowers and the bald cypress pushes the first feathery green needles over the swamp water. By month's end the flowering dogwood, the state's signature spring tree, begins to open its white bracts in the warm south, setting the stage for April's full display.
