Carrots dates for a typical New York season.
Direct sow
Mar 23 to Apr 25
Keyed to the ~Apr 30 last frost. Sow 0.25" deep, 2" apart.
Fall round

~0.2 lb per plant over ~2 weeks.
New York spans more than one climate: Zone 7 is the most common zone, but the state runs 5a to 7b. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
New York growing notes
A 68-day carrot here earns up to five separate sowings across the season, but the last one, timed to finish in the cold instead of racing to beat it, tends to be the one gardeners prefer.
Slow to start, and worth five chances
Carrot seed goes into the ground direct, a scant quarter inch deep, then gets thinned hard down to 2 inches between roots, a step that decides more about the harvest than almost any other single task a grower does for this crop. The seed takes its time coming up and does so unevenly next to faster germinators in the same bed, so a row still bare a week after nearby beans have broken the surface is not a failed planting, just a slow one. Pulling a row early because nothing has shown yet wastes more plantings here than any insect does.
At 68 days to maturity against a season running well past five months end to end, carrots fit as many as five separate sowings, spaced through the warmer half of the year. A single root only averages around a fifth of a pound at harvest, the real reason this crop gets grown by the row instead of the plant. What decides whether roots come out straight is less about timing than what's underfoot: a bed on Long Island's loose, sandy ground grows a straight root with little help, while New York's heavier interior clay and glacier-strewn stony patches favor a foot of loosened, picked-clean soil, or a shorter, blunter type such as Danvers or Chantenay bred to push through resistance.
The sowing worth timing for cold, not around it
Of the five sowings a season here allows, the one worth protecting on the calendar is the last, timed to size up as the weather turns rather than to beat it. A carrot left in cooling ground through the season's first real cold holds there far better than a spring root sitting in warming soil. Napoli, a variety bred for exactly this late sowing, is worth choosing for that last planting over a type meant for a quick spring crop.
The payoff shows up on the tongue, not a thermometer, so run the comparison rather than take it on faith. Pull one root before the season's cold really sets in and taste it, then pull a second from the same row a couple of weeks later, once several hard cold mornings have passed. That second pull usually tastes sweeter and less sharp than the first, as cold nights turn starch to sugar in the root.
A fly that hunts by smell, and a caterpillar worth sparing
Carrot rust fly does its damage where nobody sees it start, laying eggs at the base of the plant so its larvae can tunnel into the root and leave rust-colored trails just under the skin, usually found only at harvest. The fly tracks down a planting mostly by scent, so a fine mesh cover sealed to the soil from the day the row goes in keeps it out more reliably than any spray timed after the fact; nothing sprayed on the outside reaches a larva already inside a root.
Parsleyworm is worth pausing over before doing anything about it. The green, black, and yellow banded caterpillar chewing on the ferny tops is a black swallowtail butterfly in an early stage, and carrots are one of the few plants its caterpillars can eat, so a planting can usually spare a little top growth to a handful of them. Moving one to a spare dill plant instead of crushing it costs nothing. Aphids cluster on those tops and rarely bother the root; a firm spray of water from the hose breaks up a light colony. Alternaria leaf blight shows up as dark, ragged spotting starting at the leaf tips and working inward during humid stretches, and a planting stripped of its top growth stops feeding the roots below, so pulling the worst leaves and keeping the row weeded for airflow protects the crop more than the foliage is worth.
In New York: watch for
The pests that find carrots here.
A middle-length season, about 171 frost-free days, means carrot overlaps carrot rust fly for a stretch each summer. Check plants every week or two and treat early.
Rusty tunnels in the roots and stunted tops.
Organic fix: Cover the row; rotate away from last year's carrots.
Big green-and-black striped caterpillars on the foliage.
Organic fix: Handpick (or leave for swallowtails); Bt if heavy.
Brown spots ringed in yellow on the oldest leaves first, darkening until the tops look scorched.
Organic fix: Water at the base rather than overhead, turn under old carrot tops, and leave 2 years between carrot crops.
Your season math: New York gives carrots about 171 frost-free days, and it needs roughly 68 days to a first harvest. That fits about 5 re-sown rounds across the season, so you can keep it coming instead of picking once.
