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
Leaf lettuce clears in about 45 days here, fast enough for up to thirteen staggered sowings a season, and the skill this state actually rewards is knowing which weeks on that long list to leave empty.
Thirteen sowings, and the gap that makes them work
Lettuce goes into the ground direct, a quarter inch deep and thinned to 6 inches apart, and a leaf type reaches its first cut in about 45 days, fast enough for up to thirteen separate sowings across a season. That count changes how the bed gets planned. Rather than one planting expected to feed a household all summer, treat each sowing as a short batch, cut hard and already replaced by the next round a few feet over, at roughly four-tenths of a pound of leaf per plant.
The skill is not filling all thirteen slots evenly through the calendar. A sowing timed to mature deep in the hottest stretch of summer struggles before it's worth cutting, and the tell is unmistakable: the core pushes up a thick stem and the inner leaves narrow and thin, a plant giving up on leaves in favor of flowering. Once that start shows, cut the whole bed that week rather than waiting to see if it settles back down, because it won't. The better calendar clusters sowings into a spring run and another once late-summer heat breaks toward fall, skipping the peak of summer, longer near the Hudson Valley than the Adirondacks.
Why the fall sowings are the ones worth protecting
Lettuce seed itself resists sprouting in hot soil, which is the practical reason a late-summer sowing meant for a fall harvest needs a small trick a spring sowing doesn't: water the row well, then lay a board or a few layers of damp burlap over it for several days until the seedlings show, keeping the soil beneath cooler and darker than the open bed around it. Pull the cover the moment sprouts appear, since it blocks light they need once they're up.
That extra step earns out. A fall sowing finishes as days cool rather than heat up, so it reaches full size without pushing toward that bitter center stem, the leaves milder for it, worth confirming with a bite of a fall head against a stressed midsummer one. The lakeside gap between zones matters here too: a bed close to the Finger Lakes often holds mild fall air longer into the season than ground a few miles back from the water at the same latitude, since deep lake water gives up stored warmth slowly, a real edge for anyone gardening near the shoreline over just inland.
Slugs after dark, cutworms at the ankle
Slugs and snails favor the damp, mulched beds a lettuce planting tends to be, and feed at night, so daytime scouting mostly finds ragged holes without a culprit in sight. Lay a flat board or shingle across a corner of the bed in the evening and lift it the next morning; slugs collect underneath it to escape daylight, and a board full of them most mornings means thinning mulch and watering earlier so the surface dries by nightfall. Cutworms attack the opposite end of a planting's life, severing a young seedling at the soil line overnight. A cardboard collar, a few inches tall, pushed an inch into the soil around each seedling for its first couple of weeks blocks the worm from reaching the stem.
Downy mildew shows first as pale, irregular blotches across the top of outer leaves, easy to mistake for sun stress until you turn a leaf over and check the underside for a felty gray to purple growth following the same pattern. A bed found with that growth needs more space around the next sowing nearby, since crowding is what lets the spores move plant to plant. Aphids show up on new growth near the center of the head and rarely amount to much on a crop cut this young; a firm rinse from the hose clears a light colony.
In New York: watch for
The pests that find lettuce here.
A middle-length season, about 171 frost-free days, means lettuce, leaf overlaps aphids for a stretch each summer. Check plants every week or two and treat early.
Clusters tucked into the heart of the head.
Organic fix: Rinse well; insecticidal soap on young plants.
Ragged holes and slime trails, worse after rain.
Organic fix: Iron-phosphate bait; a diatomaceous-earth ring; hand-pick at night.
Seedlings clipped off at the soil line overnight.
Organic fix: Collars around the stems; Bt or diatomaceous earth.
Pale yellow patches boxed in by the leaf veins, with white fuzz underneath.
Organic fix: Give plants room, let them dry between waterings, clear old leaves, and pick resistant varieties.
Your season math: New York gives lettuce about 171 frost-free days, and it needs roughly 45 days to a first harvest. That fits about 13 re-sown rounds across the season, so you can keep it coming instead of picking once.
