Foraging availability is time-specific — a plant available for 3 weeks in May requires knowing when to look, not just where. This calendar covers the Northeast (New England through Pennsylvania, including Great Lakes) and Southeast (Carolinas through Florida and Louisiana) by month. For the complete plant identification guide, see foraging for food: 40 wild edibles across North American regions.
January and February: Cold-Season Baseline
Winter foraging in the Northeast is calorie-limited but not impossible. The key strategy: focus on calorie-dense foods that persist through cold (nuts, roots, rose hips) rather than attempting to find greens.
Plant
What to harvest
Where to look
Notes
Rose hips
Hips (fruit) from prior season
Hedgerows, roadsides, forest edges
Remain on canes through February; shriveled but still nutritious
Cattail
Root starch
Frozen pond and stream margins
Roots accessible after digging through ice-free edges; starch processing requires unfrozen water
Pine needles (Northeast)
Young green needles for tea
Any pine stand
Vitamin C source; harvest youngest growth at branch tips
Chickweed (Southeast)
Entire plant above ground
Disturbed soil, garden beds, roadsides
Southeast only — grows actively in cool winter months; mats of small oval-leaved plants
Dandelion (Southeast)
Leaves, roots
Lawns, disturbed soil
Southeast only — can be harvested year-round in zones 8–9 (Florida, coastal Georgia)
March and April: First Spring Growth
The most nutritionally important foraging window opens in March (Southeast) and April (Northeast). First-growth plants are tender, low in bitterness, and high in nutrients after winter dormancy. Window: 4–6 weeks before most plants mature and become tougher or more bitter.
Plant
What to harvest
Where to look
Window
Dandelion
Young leaves (best before flower stalk emerges)
Lawns, disturbed soil
March–May (4–6 weeks of peak tenderness)
Wild ramps
Leaves and bulbs
Moist hardwood forest, north-facing slopes
April–early June; only 4–6 weeks before leaves die back — mark locations in prior year
Garlic mustard
Young leaves (first-year rosette)
Disturbed forest edges, streambanks
March–May; invasive and abundant — harvest aggressively
Stinging nettle
Young top 4–6 inches of shoot
Streambanks, disturbed moist soil
March–May (Northeast), February–April (Southeast); harvest before plant goes to flower
Chickweed
Entire plant
Garden beds, disturbed soil
March–May in Northeast before heat kills it; year-round in Southeast
Cattail
Young shoots (inner white core)
Pond and stream margins
April–May; shoots emerge when water temperature rises above 50°F
May: Peak Spring — Highest Diversity Window
May is the highest-diversity foraging month across the Northeast and Southeast. More distinct edibles are available in May than any other month. Focus on tender growth that will not be available again until next year.

Where to look
Window
Fiddlehead ferns
Tightly coiled fronds (ostrich fern only)
Moist forest, streambanks, flood plains
2–3 weeks only per season; harvest before frond unrolls to 2 inches
Elderflowers
Flat-topped white flower clusters
Forest edges, roadsides, riverbanks
2–3 weeks when in bloom; flowers before berries; shake clusters gently to check for insects
Cattail pollen
Bright yellow pollen from male flower spike
Cattail marshes
10–14 days only when the top male spike is releasing pollen; shake over a bag
Clover flowers
Pink and white flower heads
Meadows, lawns, disturbed areas
May–October; flowers from May onward in Northeast
Wild strawberry
Fruit (Southeast earlier)
Field edges, open forest, roadsides
May–June in Southeast, June–July in Northeast
Mulberry
Berries (Southeast)
Forest edges, old fields, roadsides
May–June in Southeast; very brief window — berries fall quickly when ripe
June and July: Early Summer Fruit Season

Notes
Wild blueberry
Berries
Acidic soil, forest openings, barrens
Northeast July–August; Southeast June–July; scrubby low bushes under 2 feet
Black walnut (flower)
Green nutlets (too young for eating, but mark trees)
Forest edges, roadsides
Mark walnut trees in June for September harvest; compound leaves with 15+ leaflets
Purslane
Leaves and stems
Disturbed soil, gardens, gravel
June–October; at peak after first heat wave
Lamb’s quarters
Young leaves and shoot tips
Agricultural edges, disturbed soil
June–September; harvest before plant exceeds 18 inches for best texture
July

Where to look
Notes
Blackberries
Ripe berries
Forest edges, roadsides, clearings
July–August Northeast; June–July Southeast; harvest when fully black and slightly soft
Elderberries
Dark ripe berries (cook before eating)
Roadsides, forest edges, stream banks
August Northeast, July Southeast; flat clusters hanging heavy; do not eat raw
Cattail (green head)
Green female seed head (before brown)
Marshes and pond edges
July; boil 10 minutes and eat like corn on the cob; window 2–3 weeks
Wood sorrel
Leaves and stems
Forest floor, garden edges
Active all summer; best when green and tender
August and September: Nut and Late Fruit Season
August and September are the highest-calorie foraging months — nuts, acorns, and late-season fruits provide the caloric density absent from spring greens. This is the season to harvest and cache food for winter if stationary.

Where to look
Notes
Acorns
Ripe fallen nuts
Under any oak tree
White oak acorns (round lobes) ripen first and have lower tannins; red oak (pointed lobes) in September–October
Pawpaw
Ripe fruit (Southeast)
Moist bottomland forest, river floodplains
Southeast September; ripe when soft with tropical banana-custard smell; falls quickly
Wild grape
Berries
Forest edges, fence lines, climbing on other plants
August–September; sour when unripe, tart when ripe; small clusters of dark grapes
