April is the great unlocking of the Vermont spring — ice goes out of the lakes, the first spring ephemerals carpet the warming woods, and migration builds toward its May peak. The high country is still brown and cold, but the valleys turn green and loud almost overnight.
Week by week in April
April 2–8
- Eastern phoebes sing from barn eaves and tree swallows and bluebirds claim nest boxes as the first migrants arrive in numbers.
- The first spring ephemerals stir in the warm valley woods — bloodroot and hepatica emerge as the forest floor begins to wake.
- On the first warm, sunny afternoons, overwintered mourning cloaks take wing, basking on sunlit logs sometimes with snow still nearby.
April 9–15
- Ospreys return to their platform nests and the first yellow-rumped and palm warblers move through the still-bare woods.
- Red trillium, trout lily, and Dutchman's breeches open on the rich hardwood forest floor before the canopy leafs out.
- As beds dry enough to crumble, direct-sow peas, spinach, lettuce, and radishes, and plant onion sets and seed potatoes in the warmer zones.
April 16–22
- Broad-winged hawks begin kettling over the ridges and hermit thrushes — the state bird — return to sing from the hillsides.
- The Lyrid meteor shower peaks around April 22, radiating from near bright Vega, best after midnight from a dark site.
- Serviceberry (shadbush) opens its white flowers along woodland edges, one of the first native trees to bloom.
April 23–29
- Common loons return to nesting lakes and the first ruby-throated hummingbirds reach the warm valleys — get feeders ready.
- The first wild fiddleheads and ramps (wild leeks) appear at markets and farm stands as the maple run finishes up. Cook them thoroughly before eating — boil 15 minutes or steam 10–12; never raw.
- The small, fast spring azure appears — one of the first freshly hatched butterflies of the year — alongside cabbage whites and commas.
Birds This Month
April migration accelerates through Vermont. Eastern phoebes sing from barn eaves, tree swallows and eastern bluebirds claim nest boxes, and the first warblers — yellow-rumped, palm, and pine — move through the still-bare woods. Ruby-crowned and golden-crowned kinglets, hermit thrushes (the state bird, now back on territory), winter wrens, and brown creepers fill in, while chipping and field sparrows arrive to sing.
The Champlain Valley is the spring waterbird stage: Dead Creek WMA and the lake's bays host migrating ducks, common loons returning to nesting lakes, grebes, and the first shorebirds on the mudflats. Ospreys return to their platform nests, broad-winged hawks begin their kettling passage over the ridges, and wild turkeys gobble and strut through the open woods. Woodcock still display at dusk in the wet thickets.
This month's tip: get hummingbird feeders ready for the very end of the month, and listen at dawn — the chorus grows richer by the week as more migrants pour in from the south.
What's Blooming
April is the start of the spring-ephemeral show, the brief, magical window when the forest floor blooms before the canopy leafs out. In the rich hardwood woods of the Champlain Valley and lower mountains, watch for red trillium (wake-robin), trout lily in mottled-leaf colonies, Dutchman's breeches, spring beauty, bloodroot, hepatica, and wild ginger emerging from the leaf litter. Marsh marigold glows gold in wet woods and seeps statewide.
These ephemerals race to flower, fruit, and store energy in the few sunlit weeks before the trees shade them out. In gardens, crocus, daffodils, hyacinths, and the first tulips bloom in the valleys, and forsythia and pussy willow brighten the yards. Timing runs weeks later in the cold Northeast Kingdom than in the warm lower Champlain Valley, so the bloom climbs the hills and moves north across April — a slow green wave following the warmth uphill.
Garden This Month
April is when Vermont gardens finally come to life — but it pivots entirely on soil and frost. As beds dry enough to crumble (never work them wet), direct-sow the cool-season crops that thrive in cold soil: peas, spinach, lettuce, radishes, carrots, beets, kale, and onions. Plant seed potatoes and set out hardened-off broccoli, cabbage, and onion transplants toward month's end in the warmer zones.
Keep the warm-season seedlings — tomatoes, peppers, squash — growing indoors; Vermont's last frost doesn't pass until mid-to-late May, later in the north, so they stay inside. Outdoors, finish cleaning beds, cut back perennials and grasses, top-dress with compost, plant bare-root trees and shrubs and asparagus crowns, and divide crowded perennials as they emerge. Rake gently — early bees and other insects shelter in the leaf litter. Watch the forecast; hard frosts and even late snow remain entirely normal.
Zone 3b (Northeast Kingdom & high country): snow is finally going but hard frost is routine and the last freeze is weeks off. Start more seedlings indoors, prep beds as they dry, and direct-sow only the hardiest crops (peas, spinach) at the very end of the month if soil allows.
Zone 4b (central Vermont & valleys): direct-sow cool-season crops — peas, spinach, lettuce, radishes, carrots, beets — as soil dries, and set out onion sets and potatoes. Harden off cabbage and broccoli for transplanting late in the month, but keep frost protection handy.
Zone 5a (lower Champlain Valley): the busy cool-season planting month — sow peas, greens, roots, and brassicas, plant potatoes and onions, and transplant hardened-off cabbage family early. Hold tomatoes and tender crops; the last frost is still a few weeks out near mid-to-late May.
What's at the Farmers Market
April markets bridge winter and spring. Maple is still front and center as the season's syrup finishes — fresh jugs, maple cream, and candy fill the tables. The winter storage crops are winding down: the last potatoes, carrots, onions, beets, and winter squash, plus cold-storage apples.
The first true spring growth arrives — overwintered and hoop-house spinach and greens, microgreens, the earliest rhubarb, and the first wild fiddleheads and ramps (wild leeks) from the woods late in the month. Cheese, eggs, honey, and grass-fed meats remain staples. It's also the start of plant-start season, with seedlings appearing for sale. Choose the freshest, crispest greens and use them within a few days; for fiddleheads, pick tight, bright-green coils and refrigerate dry in a paper bag, using promptly — and always cook them thoroughly (boil 15 minutes or steam 10–12; never raw).
Night Sky This Month
April's milder evenings make for comfortable stargazing as the spring sky takes over. Leo rides high in the south with bright Regulus, the Big Dipper climbs to its peak overhead, and its handle arcs down to brilliant orange Arcturus in Boötes rising in the east — "arc to Arcturus." The winter stars sink into the western dusk, with Orion and Sirius setting earlier each night.
The Lyrid meteor shower peaks around April 22, a modest but reliable shower radiating from near the bright star Vega, which clears the northeast horizon late in the evening — best after midnight from a dark site. Vermont's rural ridges and the Kingdom give the darkest skies, and the northern horizon may still flare with the aurora borealis during geomagnetic activity.

Butterflies & Pollinators
April is when Vermont's butterflies truly return to the air. The overwintered adults are out in force on warm, sunny days: mourning cloaks patrol woodland edges and sunny clearings, joined by eastern commas, question marks, and the small, fast spring azure — a tiny blue that is one of the first new butterflies of the year, hatched fresh rather than overwintered as an adult. Cabbage whites appear in gardens and fields. These early fliers nectar on willow catkins, dandelions, and the first spring ephemerals, and the basking mourning cloaks take sap from broken branches and sugar-maple wounds. Monarchs are still moving north through the southern states, with the first arrivals into Vermont still a month or more away. Warm, still afternoons in the valleys are the best time to look; cold snaps send everything back into shelter to wait for the next thaw.

Trees This Month
April is the slow green ignition of the Vermont woods. The earliest trees flower before they leaf: red maple and silver maple redden the wetlands, aspens, willows, and alders dangle catkins, and the American elm flowers high overhead. By late month, leaf-out begins in the warm valleys with the soft red of unfurling red maple and the pale green of aspen and birch, climbing the hills as the weeks pass.
The sugaring season closes as the sugar maples bud out — once the buds break, the sap turns and the syrup season is over. Native serviceberry (shadbush) opens its white flowers along woodland edges, one of the first trees to bloom, and the conifers hold their green through it all. The high Green Mountains and the Kingdom stay bare and brown well into May, the leaf-out a moving wave that follows the warmth uphill and northward.
Weather & Daylight
Across Vermont, a typical April day averages a high near 52°F and a low near 30°F, with about 3.6 inches of precipitation — statewide averages from the 1991–2020 U.S. climate normals.
Real warmth returns, days near 52F feel welcoming after winter, though chilly 30F nights still call for a jacket.
| Average high | 52°F |
|---|---|
| Average low | 30°F |
| Precipitation | 3.6 in |
| Sunrise (mid-month) | 6:08 ET |
| Sunset (mid-month) | 19:33 ET |
Figures are statewide averages over the 1991–2020 U.S. climate normals; local conditions vary with elevation and distance from the coast. Sunrise and sunset are computed for a midstate point on the 15th (ET).
