Florida Nature Guide: March 2026
March is Florida's spring crescendo — the first big wave of trans-Gulf migrants reaches the southern peninsula and the Dry Tortugas, the wading-bird rookeries are crowded with nests, and the roadsides blaze with tickseed and other wildflowers. The dry season is at its peak, the gardens race the coming heat, and the nights are still cool and clear.
What to look for this week
- The Christmas Bird Count season peaks across Florida, with Merritt Island and the Everglades tallying huge numbers of wintering ducks, spoonbills, and wood storks.
- The Quadrantid meteor shower peaks in a brief, sharp burst around January 3 — best after midnight from the dark Kissimmee Prairie or Big Cypress.
- The cool-season vegetable garden is in full production statewide; harvest broccoli, collards, and lettuce, and keep frost cloth ready in the north.
Birds This Month
March opens Florida's spring migration, one of the great birding events in North America. Trans-Gulf migrants begin pouring into the southern peninsula, and by late month the Dry Tortugas — seventy miles west of Key West — become a legendary migrant trap and seabird colony, where exhausted warblers drop into the few trees on Garden Key and Sooty and Brown Noddies, Masked and Brown Boobies, and Magnificent Frigatebirds wheel over Bush Key. The first Black-and-white, Hooded, Prothonotary, Northern Parula, and Yellow-throated Warblers, Louisiana Waterthrush, and Swallow-tailed Kites arrive across the state.
The wading-bird rookeries are at full nesting tilt — Wood Storks, Great and Snowy Egrets, Roseate Spoonbills, Anhingas, and herons crowd the cypress at Corkscrew Swamp Sanctuary and the south Florida colonies. Purple Martins and Northern Rough-winged Swallows are back, the endemic Florida Scrub-Jay is nesting, and the Snail Kite and Limpkin are conspicuous on the central-Florida marshes and spring runs. Wintering ducks thin out at Merritt Island, but shorebirds build on the flats, and resident Northern Mockingbirds, the state bird, and Northern Cardinals are in full song.
What's Blooming
March is the great explosion of Florida's spring wildflowers. The state wildflower, coreopsis (tickseed), begins washing roadsides and fields yellow, planted in highway wildflower strips and blooming wild across the flatwoods. The native azaleas peak — wild pinxter and Florida flame azalea light the north Florida woods pink and orange — and Carolina jessamine, spiderwort, blue-eyed grass, lupine, phlox, and sundial lupine spread across the sandhills and scrub.
In the dry pine flatwoods and prairies, blackroot, pawpaw, partridge pea, and the showy Florida violets open, and the Lake Wales Ridge scrub holds rare endemics found nowhere else on earth. South Florida's hammocks and pinelands keep their tropical bloom going with firebush, beach sunflower, scorpionstail, and tropical sage. The orange blossoms — the state flower — perfume the central groves as the citrus finishes its heavy bloom, the dogwoods and redbuds flower in the Panhandle woods, and gardens overflow with azaleas, amaryllis, bromeliads, and the first gaillardia.
Garden This Month
March is the prime warm-season planting month across Florida, and the great race against the coming heat. After the last frost, set out and direct-sow tomatoes, peppers, eggplant, squash, cucumbers, beans, sweet corn, and melons — the goal everywhere is to get fruiting crops established early enough to harvest before the punishing summer heat, humidity, and rains shut them down by June. The last of the cool-season greens — lettuce, broccoli, collards — should be harvested before they bolt in the warming weather.
This is also the time to plant the heat-loving Southern crops that thrive when tomatoes fail: okra, southern (field) peas, sweet potatoes, and boniato. The dry season is at its driest, so water new transplants deeply and mulch heavily to hold moisture. Fertilize the established beds, watch for the first aphids and caterpillars as the warmth brings out the insects, and stake and trellis the tomatoes and beans. Plant warm-season herbs — basil, oregano, lemongrass — and set out tropical fruit trees like mango, avocado, and banana in the frost-free south as the soil warms.
Zone 8b (north Florida & the Panhandle): the spring planting season finally opens as frost danger passes by mid-month. Set out tomatoes, peppers, squash, beans, cucumbers, and corn, and start the heat-lovers — okra, southern peas, and sweet potatoes — for the long hot summer ahead.
Zone 9a (north-central Florida): warm-season planting is in full swing. Get tomatoes, peppers, eggplant, squash, beans, and corn in early so they fruit before the summer heat, and keep harvesting the last of the cool-season greens before they bolt.
Zone 9b (central Florida): race the heat. Finish setting out warm-season vegetables now, mulch heavily against the drying dry-season winds, and begin shifting toward the heat-tolerant tropical crops that will carry the garden through summer.
What's at the Farmers Market
March markets brim with the tail end of the citrus season and the spring vegetable flood. Late Valencia oranges, the prized juice orange, peak now alongside the last grapefruit, tangerines, and honeybells from the central and Indian River groves. Plant City strawberries are still pouring out of the Hillsborough and Polk county fields in their final big month, and central-Florida blueberries are ramping up as the earliest crop in the nation.
The winter and spring vegetable fields keep producing heavily — tomatoes, bell peppers, snap beans, sweet corn, cucumbers, squash, cabbage, lettuce, and greens from the southern and east-coast growing regions — and the first spring sweet corn from the Everglades muck region and Vidalia-style sweet onions appear. Look for Florida honey (the orange-blossom honey is at its finest now), boiled peanuts, and stone-ground grits at the roadside stands. Pick strawberries fully red and refrigerate them unwashed in a single layer, store blueberries dry and cold, keep tomatoes at room temperature, and hold citrus cool for the last weeks of the season.
Night Sky This Month
March is one of the finest stargazing months in Florida — the dry season still keeps the air clear, the nights stay mild and comfortable, and the sky pivots from winter's brilliance to spring's deep galaxy fields. Kissimmee Prairie Preserve State Park, the state's first certified International Dark Sky Park, holds some of its best star parties now on the wide unlit prairie, and the dark skies of Big Cypress National Preserve and the Everglades back roads reward the drive from the coastal cities. The flat Florida horizon lets the whole dome stand out.
In the evening, Orion still rides the western sky as Leo the Lion climbs high with bright Regulus, leading the spring constellations. Late at night the rich galaxy field of Virgo and Coma Berenices rises in the east — a paradise for a small telescope under dark Florida skies — and the Big Dipper swings high in the north, its handle arcing down to bright Arcturus. The spring equinox falls near March 20, evening out day and night. There is no major meteor shower this month, so the moonless nights are best spent sweeping the galaxy clusters.

Butterflies & Pollinators
March brings Florida's butterfly fauna roaring into spring. The state butterfly, the zebra longwing, and the gulf fritillary are abundant on passionflower across the peninsula, and the first big spring broods of giant, eastern tiger, spicebush, and palamedes swallowtails fill the woods and gardens. Cloudless sulphurs, orange-barred sulphurs, white peacocks, common buckeyes, red admirals, American ladies, long-tailed skippers, and the coastal great southern whites are all on the wing, and monarchs are breeding on milkweed across the central and southern counties.
This is a fine month to watch for spring specialties and migrants. Painted ladies and red admirals move north through the state, the pierids stream along the coasts, and the southeast-coast hammocks keep their year-round atala hairstreaks emerging from coontie. In the pine flatwoods and scrub, look for the early frosted and Henry's elfins, Juniper hairstreaks, and the small native blues. With the wildflowers at their spring peak, the nectar is everywhere — tickseed, lupine, blanketflower, firebush, and Spanish needles draw clouds of butterflies along the roadsides and field edges. It is one of the best months of the year for butterflying in Florida.
Trees This Month
March is full subtropical spring in the Florida trees. The bald cypress of Corkscrew, Big Cypress, and the blackwater rivers flush their feathery new needles a brilliant fresh green, transforming the bare gray swamps almost overnight. The live oaks finish their leaf exchange and drape long catkins of yellow-green pollen, while the red maple samaras spin down over the lowlands. In the Panhandle woods, the flowering dogwood, redbud, fringetree, and wild plum bloom white and pink among the new green.
The Panhandle longleaf pine sandhills shed clouds of golden pollen across the wiregrass, dusting cars and porches for miles, and the slash and loblolly pines flush new growth. The native magnolias and the southern crabapple begin to flower, and the gardens fill with blooming azaleas, dogwoods, and the first jacaranda and tabebuia in the south. The citrus groves carry their last fragrant orange blossoms even as the new fruit sets. The state tree, the sabal palm, and the south-coast mangroves hold their evergreen crowns, ready for the wet season ahead.
