Zone 7b Planting Calendar: Month-by-Month Guide to Planting Vegetables

Here at Manhasset Gardens on Long Island, we plan the whole year around two dates: the night the last freeze ends and the night the first one returns. Turn those two dates into a simple month-by-month plan and sowing, setting out, and picking become routine instead of guesswork. This guide does exactly that for a mild zone with a long, generous season.

The 7b Growing Season at a Glance

This zone sits in the mild shoulder of the official zone map, with average annual minimum temperatures between 5 and 10°F. That band wraps Long Island, New York City, and much of the New Jersey coast, and it delivers a growing season of roughly 200 frost-free days — long enough for two full plantings of many crops.

Know Your Last Frost Dates

Everything starts with your last frost date. On Long Island the last frost typically lands in mid-April and the first frost in early November. Your exact date depends on elevation, wind, and nearby water — a microclimate effect that can shift plantings by a week or more. To time tomatoes, count back six to eight weeks before that date.

When to Start Seeds Indoors

Warm crops get a head start inside. Begin tomatoes and peppers six to ten weeks before your average final freeze, and brassicas four to five weeks. Harden off the babies for a week before they move outside — seedlings started indoors need gradual sun or their leaves scorch.

Month-by-Month Planting Dates

These recommended planting dates assume an average year on the North Shore; gardens in the Piedmont and mid-Atlantic run about a week behind us in spring. The charts NC State publishes for central North Carolina follow the same logic.

Month What to do
January Map crop rotation and order seeds for the vegetable garden.
February Start seeds: onions, celery, and artichoke first; peppers and eggplant late in the month.
March Direct sow peas, spinach and kale, arugula, radish, and carrots as soil dries.
April Set out onions, broccoli, and cabbage; plant carrots and succession lettuce.
May Once the risk of frost has passed, transplant tomatoes, peppers, and eggplant; plant cucumbers and beans from seed.
June Plant squash and melons from seed in warm soil; heat-loving crops like sweet potatoes take off.
July Start fall brassicas indoors; side-dress tomatoes; watch for pest pressure on squash.
August Plant fall carrots, scallions, and lettuce from seed; move out broccoli and kale starts.
September Set out fall brassicas; plant garlic late in the month.
October Plant fruit trees and berry bushes while soil is still warm; clear spent beds.
November Final harvest of carrots and kale; mulch beds to overwinter garlic and hardy greens.
December Order seeds and sketch next year.

Best Vegetables to Plant in Spring

Most vegetables in zone 7 follow a two-act rhythm. Spring planting starts the moment soil can be worked: cool-season crops like lettuce, spinach, arugula, radish, collards, turnip, and cabbage tolerate some frost and grow sweet in cold air. Warm season plants wait for warm soil. Once summer heat means lettuce bolts, lean on warm-season crops: tomatoes, peppers, eggplant, cucumber vines, and okra. High temperatures stall tomato fruit set in July, but the long fall more than makes up for it. Perennial vegetables like asparagus deserve a permanent bed of their own.

A few proven varieties for this climate: ‘Sun Gold’ and ‘Celebrity’ tomatoes, ‘Ichiban’ eggplant, ‘Cal Wonder’ peppers, and ‘Provider’ bush beans — dependable performers that forgive beginner mistakes. Put in a second sowing of bush beans in mid-July; they ripen during the mild September stretch when heat stress eases.

Fall Vegetable Planting

Fall vegetable planting is the secret second season. The planting window opens in late July, when fall roots go in — they are best sown in late July through mid-August. Broccoli, cabbage, and brussels sprouts started in shade grow into the cooler temperatures of autumn, and early fall plantings of lettuce and spinach often outperform spring ones: fewer slugs, steadier moisture, and pest pressure that fades as nights cool. Keep seeding through late summer, with the final spinach in by mid-September. Garlic goes in from early October through Thanksgiving; break bulbs apart the day you plant, point the cloves up, and mulch three inches deep. If a nematode problem hit your roots this year, solarize the empty bed in August heat.

Growing Tips for a Better Harvest

A few habits make the whole system hum. Let the ground thaw and drain before digging — working wet soil ruins its structure. Carrots germinate slowly in cold ground, so keep the seedbed moist until small seeds germinate evenly. Seeds sown directly in the garden often beat indoor starts for root crops, and the cucurbit family prefers direct seeding too: melons and squash sulk after root disturbance. Select varieties with short days to maturity for late sowings; they mature quickly before days shorten. Water deeply once or twice a week rather than sprinkling daily, and feed leafy greens with nitrogen while fruiting crops want phosphorus and potassium. Count everything from seed to harvest and log what worked — a rain gauge and a cheap notebook teach you more than any app. Seasoned zone 7 gardeners fine-tune the calendar each year, because every gardener’s dates shift by a week or two. Plant at the right time, and the garden mostly takes care of itself.

Frequently Asked Questions

When to plant vegetables from seeds in 2026?

Count back from your mid-April average: tomatoes six to eight weeks, peppers eight to ten, brassicas four to five. Hardy kinds go straight outside from mid-March.

How do I determine my planting zone?

Enter your zip code into the official interactive map, or start with our guide to hardiness zones for the quick version.

Is July too late to plant beets?

No, with a caveat: early July sowings still make full roots in most years, and later ones give you tender baby greens instead.

What is the hardest vegetable to grow?

Head cauliflower is the classic answer — it wants rich soil, steady moisture, and uninterrupted cool weather. Celery and heading lettuce frustrate beginners too.

What can I direct sow in early spring?

Peas, lettuce, spinach, radishes, and carrots go straight into the ground as soon as it can be worked.

Which crops are better started indoors?

Tomatoes, peppers, eggplant, and brassicas reward indoor starts; roots and the melon family prefer going straight into warm soil.

Can I keep harvesting through November?

Yes. Cold frames and row covers add frost protection and stretch cut-and-come-again greens well into December in sheltered spots.

Are there perennial vegetables for this climate?

Yes. Rhubarb and sorrel return reliably, and the classic spring spear crop keeps producing for decades once established.
