First-Year Vegetable Garden Checklist: From Site to First Seedlings

By Paul Gunder · How we check our sources

Updated November 8, 2026

Figures checked against their sources on November 8, 2026; next check May 8, 2027.

In short: Pick a spot with enough sun and water, test the soil, check pH against what you plan to grow, space and rotate by the charts, and start seed in clean mix with warmth and light.

How this list is built

A first garden fails less from one big mistake than from a few skipped steps. This checklist walks through them in the order a new gardener meets them: where to put the garden, what is in the soil, when frost lets you plant, how to lay out the beds, how to start seed, and one habit for the growing season. Every item names the Extension or NOAA source behind it, and every figure is read from the same typed data as the charts elsewhere on this site, so the numbers cannot drift from them.

Site and soil

Penn State Extension calls the choice of spot crucial and says most vegetables need at least 6 to 8 hours of full sun every day, along with plenty of moisture. It also says the quality of the soil is essential when you begin, and suggests raised beds if you are worried about yours. A soil test through your state Extension office is the way to learn what you have. When the result comes back, University of Wisconsin-Madison Extension gives about 6.5 as ideal for most vegetables, and warns that lime raises pH, so add it only when a test says to.

Frost and timing

Your last spring frost decides when tender crops can go out. University of New Hampshire Extension puts it bluntly: find the date for your area first, and do not seed or transplant frost-sensitive plants before it. The frost dates lookup gives that date for the NOAA weather station nearest you, along with the later, safer date that holds in nine years out of ten, which is the one to use for plants you cannot cover.

Layout and rotation

NC State Extension puts tomato plants 18 inches apart; its table gives the distance between plants and no row width, so take row width from the seed packet. Iowa State advises keeping a plant family out of one location for 3 to 4 years, which only works if you write down what you planted, so the checklist asks you to record each crop's family. The rotation page lists the families.

Starting seed

Illinois Extension is the source for most of the seed-starting items: new, well-draining, sterile mix rather than garden soil or compost, warmth around 70 to 75°F, and strong light once seedlings emerge. Alabama Extension's germination chart shows why warmth matters; tomato's floor is 50°F. Before the seedlings go in the ground, the University of Minnesota hardens them off over 2 weeks, starting with a few hours of afternoon shade and building up to full sun.

Worked example: planning a tomato bed

Say your sunniest spot gets the hours above, and the soil test comes back close to the pH target. You tick the site and soil items. You look up your station's frost dates and mark the later one, because tomatoes are frost-sensitive. For layout you set the plants at the gap in the spacing item and write nightshade beside the bed in your notes, which tells next year's you to put a different family there. Count back from the frost date to start the tray in clean mix at the tray temperature, give the seedlings strong light, and begin hardening them off 2 weeks before planting day. Each of those is a tick on the list, and none needs a purchase beyond a soil test and some seed-starting mix.

What this list leaves out

It does not size a bed or work out how much soil to buy: that is a calculation, and the garden calculators on Calcimator are the place for it. It does not recommend a fertilizer or pesticide, and where a product is involved, its label is the guide. For problems along the way, the seeds not germinating troubleshooter covers the common seed-tray failures.
