How to Start a Vegetable Garden in 2027: A Month-by-Month Plan (Zones 4-7)

A month-by-month plan turns the fuzzy wish "I want a garden" into a calendar you can actually follow. Below is what to do each month across zones 4 through 7, with named varieties, sowing depths, and spacings you can copy straight into your hands.

Know your frost window by zone

Zones 4 to 7 don't flip into summer on the same day, so anchor every decision to your own last spring frost and your first fall freeze. A fair way to think about the stretch:

• Zone 4: last frost around May 10-20; first freeze near October 15
• Zone 5: last frost mid-to-late April (April 15-30); first freeze late October (October 25 to November 1)
• Zone 6: last frost around mid-April; first freeze mid-to-late October
• Zone 7: last frost mid-March; first freeze late October to mid-November

Two rules carry most of the weight. Cold-hardy crops — lettuce, radish, pea, spinach, onion, carrot, broccoli, kale — go in as soon as the soil works, that is 4 to 6 weeks before your last frost. Tender crops — tomato, pepper, cucumber, squash, basil — wait until two weeks after it. Every date below is an offset from your own frost, not an absolute calendar day, so shift them to fit your spring.

Winter (December-February): plan on paper

This is the least glamorous, highest-return stretch of the year.

• Sketch your space on grid paper or a napkin. Note how many hours of direct sun you get — tomato and pepper want six, lettuce and radish are fine with four or five, and shade in the afternoon is a real problem in cities.
• Pick your list of eight to twelve varieties and buy the seeds in January or February, when they're cheapest and in stock. For a first container garden, a forgiving short list is: cherry tomato 'Sungold' or 'Patio Princess', pepper 'Jalapeno', lettuce 'Buttercrunch', radish 'Cherry Belle', bush bean 'Provider', carrot 'Nantes', spinach 'Space', and basil 'Genovese'.
• Write down your last frost date and the two dates that matter around it: last frost minus six weeks (start hardy crops) and last frost plus two weeks (start tender crops).

March: start the slow ones indoors

Tomato, pepper, and basil are the three crops that take too long outdoors to be worth it, so they get a head start under a grow light or on a sunny windowsill. Start them indoors 6 to 8 weeks before your last frost — for a mid-April date, that lands in late February or March.

Sow tomato and pepper seeds in small trays or 4-inch pots, pressed in about 1/4 inch deep, and keep the medium warm (70-75 F at the seed bed gives you a 5-to-10 day faster germination). Thin to the strongest plant per pot when the first real leaves appear. Lettuce and spinach germinate faster and don't need the heat; sow those 1/8 inch deep, and they're ready to transplant in 4 to 6 weeks.

April: plant the hardy stuff

This is the first real dirt month. As soon as the soil holds together instead of crumbling, get these in:

• Pea — varieties like 'Sugar Ann'; sow 1 inch deep, 1 inch apart in the row, with a trellis or string for the poles.
• Lettuce — 'Buttercrunch'; 1/8 inch deep, 8 inches apart, rows 12 inches.
• Radish — 'Cherry Belle'; 1/2 inch deep, 2 inches apart. You can be eating these 25 to 30 days from sowing.
• Spinach — 'Space'; 1/2 inch deep, 3 inches apart. It bolts fast in heat, so this is a spring crop, not a summer one.
• Onion — set out 3- to 4-inch transplants, 3 to 4 inches apart, with roots just at the soil line.

Where you're in a warmer zone (6 or 7) and your soil is ready a month early, add carrot 'Nantes' — 1/4 inch deep, 2 inches apart in the row, rows 12 inches — and bush bean 'Provider', 1 inch deep, 3 to 4 inches apart.

May: fill it in and mulch

After your last frost, it's time to get the tender things in and protect what you've planted.

• Tomato — transplant 'Sungold' or 'Patio Princess' deep, burying two-thirds of the stem (the buried stem grows roots, which is a feature, not a mistake); space plants 18 to 24 inches apart.
• Pepper — 'Jalapeno' at 18 inches apart, set out so the crown sits just below the surface.
• Potato — 'Yukon Gold', cut pieces sown 4 inches deep, 12 inches apart in the row.
• Basil — 'Genovese', 10 inches apart, one of the last things to go in since it hates a cold root.
• Cucumber and summer squash — 1/2 inch deep; cucumber 12 inches apart, squash 15 to 18 inches.

Now mulch. Two to three inches of straw or shredded leaves over the whole bed holds the root zone at a steadier 65-70 F and keeps the weeds down, which in a first year is more than half your job.

June-July: succession planting and maintenance

Summer isn't a planting month, it's a maintenance month — with one exception that is.

• Succession sow lettuce, radish, and bush bean every two to three weeks so you're always harvesting and never staring at a bare bed.
• Pinch and harvest basil, tomato, and pea regularly; steady picking keeps them producing far longer than leaving them to set seed.
• Water deeply two to three times a week at the soil line, not on the leaves — wet leaves are where powdery mildew sets up.
• Mulch again in July; by now the first layer has flattened, and topping it up is the cheapest yield-boost you'll make all season.

August-September: the second garden

Here's a small secret: a zone 4 to 7 fall is nearly as good as spring for a lot of crops, and it's calmer because there are no weeds yet. Count backward from your first freeze and you find these windows open up.

• Carrot 'Nantes' and radish 'Cherry Belle' — start 60 to 70 days before your first freeze (for a mid-October date, that's late July, which is why August is a second planting window in the south and a light one in the north).
• Spinach 'Space' and kale 'Lacinato' — start 6 to 8 weeks before first freeze.
• Broccoli 'Purple Sprouting' or 'Catalina' — start 6 to 8 weeks before, set out 12 inches apart.
• Onion overwintering in zones 5 to 7 — set out thin sets that will sprout again next spring.

Keep one simple rule: the goal is that leaves, not fruit, are on the plant when the freeze arrives, because you want to be harvesting, not gambling.

October: protect what's left

When the first frost warning lands, don't just let the beds go.

• Pull anything you won't eat before it goes (tomato, pepper, basil) and bring them in.
• Spread a 3-inch blanket of straw or leaves over the soil; next spring it becomes your free compost.
• In zones 5 to 7, garlic cloves go in now — plant them 6 to 8 inches apart, 2 inches deep, pointed end up. That's your crop for 2027's late season and your head start on next year.
• Sketch what worked and what bolted onto the back of your seed order so 2027 starts one step ahead.

Quick wins to try this fall

• Sow radish 'Cherry Belle' (1/2 inch deep, 2 inches apart) in any spare pot this month if you're zone 5 to 7 — it will still germinate before the kill frost.
• Add a 2-inch layer of shredded leaves or straw to every bed you touched this season; it costs nothing and feeds next spring.
• In zones 5 to 7, slip garlic cloves in this week, 6 to 8 inches apart, 2 inches deep — that's a crop you can't start any other way.
• Order your 2027 seed list in the next few weeks, before the winter sales close, and write the frost dates on the outside of the envelope.
• Stake a cold-frame or hoop over one sturdy bed so that same bed keeps producing into November.
