Snap Peas dates for a typical New York season.
Direct sow
Mar 9 to Apr 20
Keyed to the ~Apr 30 last frost. Sow 1" deep, 2" apart.
Fall round

~0.4 lb per plant over ~3 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
Snap peas want New York's cold, wet spring exactly as it arrives, and the plant that struggles here isn't fighting frost, it's racing the heat that eventually shuts flowering down.
A crop that wants the ground before it feels ready
Snap pea seed goes an inch deep into New York soil, thinned once up to a tight 2 inches apart, and reaches a first picking in about 62 days. Unlike a warm-season crop waiting on the last frost date, peas go into cold ground on purpose, tolerating a frost the young plant shrugs off far better than the heat that arrives later. The soil test matters more than the calendar here: squeeze a handful from the bed, and if it packs into a mud ball that holds its shape instead of crumbling, the ground is still too wet to work, especially on this state's heavier interior clay, and seed sown into it rots before it sprouts.
That early appetite for cold ground is also why this crop supports as many as eleven staggered sowings across a season here, spread across both a spring run and a second one aimed at fall. A trellis or a length of netting a few feet high, set up before seed goes in rather than after the vines need it, keeps the crop off the ground and easier to pick. At around four-tenths of a pound per plant, most of that return comes from picking regularly rather than letting pods sit and toughen.
The real limit is heat, not the frost this crop shrugs off
Spring is the easier of the two windows here, since a pea planted early simply grows as days lengthen and warm, flowering and podding without much drama until real summer heat sets in. Once that heat arrives, flowering slows and then stops almost entirely, not because the plant is dying, but because it stops committing energy to flowers in conditions it isn't built for, resuming once cooler weather returns. That's the practical reason succession sowings cluster toward spring and again toward fall here rather than spreading evenly across summer; a pea sown to mature in the hottest stretch mostly just sits.
The fall window asks more of the timing than the spring one does. Seed sown too early to make the fall frost date sits in soil still holding onto summer heat, which slows germination and can rot seed in ground too warm and damp at once; sown too late, the planting runs out of days before reaching a real harvest. Watering the row well right after sowing a fall crop, then keeping the soil from crusting over in whatever heat remains, gets seed through that early stretch faster and narrows the window it's exposed to those conditions.
One aphid, one mildew, and a crop usually done before either matters much
Pea aphid is larger and easier to spot than most garden aphids, clustering along stems and on growing tips and pod undersides rather than hiding in tight curls of new leaf the way smaller species do. A planting checked once a week through flowering catches a colony before it spreads, and a firm spray of water aimed at stems and pod clusters clears most of it without further treatment; a trellis-grown planting is also easier to check than one sprawling on the ground, since both sides of the vine stay in reach.
Powdery mildew shows as a flat, white, dusty coating across older leaves, and on this crop it tends to arrive right as rising humidity and warmth are already ending the spring planting's productive run, so the two pressures usually land together. A planting already slowing from heat gets little extra benefit from treating mildew at that point, and the better use of the same effort is picking the last of what's there and clearing spent vines to make room for the next sowing. A fall crop, maturing as humidity drops back down, usually meets far less of it, one more reason that second window is worth the trickier timing at the start.
In New York: watch for
The pests that find snap peas here.
A middle-length season, about 171 frost-free days, means snap pea overlaps pea aphid for a stretch each summer. Check plants every week or two and treat early.
Clusters on the tender growing tips where new tendrils form.
Organic fix: Knock colonies loose with a firm blast from the hose before they build.
White powder on leaves after warm dry days and cool, dewy nights.
Organic fix: Grow resistant varieties and trellis so vines are not lying on each other.
Root rot
Seedlings stall and yellow from the bottom up, and a lifted plant shows soft brown roots instead of firm white ones.
Organic fix: Sow into a raised or well-drained bed, work compost into heavy ground, ease off the water, and move peas to fresh ground next year.
Your season math: New York gives snap peas about 171 frost-free days, and it needs roughly 62 days to a first harvest. That fits about 11 re-sown rounds across the season, so you can keep it coming instead of picking once.
