What to Plant in a Garden

What to plant in a first garden

For US beginners in Zones 5–9, start with tomatoes, lettuce, green beans, and one herb — these four crops are forgiving, productive, and cover the full gardening season from early spring to first frost.

The urge to plant everything at once leads to most first-garden failures. A focused plant list gives you space to observe each crop, understand its needs, and actually harvest before the season ends.

This guide covers:

• What to plant by season (cool-season vs. warm-season)
• What to plant by zone (Zone 5–11)
• What produces the most food in limited space
• What to avoid in a small first garden

Cool-season vs. warm-season crops

Every garden vegetable belongs to one of two timing categories. Getting this right is more important than any other planting decision.

Cool-season crops (plant in spring and again in late summer for fall):

• Lettuce, spinach, arugula, kale
• Peas (snap, snow, shell)
• Radishes and turnips (fastest harvest: 22–30 days for radishes)
• Cilantro, parsley, chives
• Brassicas: broccoli, cabbage, cauliflower

Warm-season crops (plant after last frost):

• Tomatoes, peppers, eggplant
• Cucumbers, zucchini, summer squash
• Beans (bush and pole)
• Basil
• Corn, melons, winter squash (need more space)

The four best beginner crops

1. Tomatoes

Tomatoes are the most grown home vegetable in the US for a reason: they produce enormous yield in small space and reward the gardener’s attention.

A single indeterminate tomato plant in a 15-gallon container can produce 15–30 lbs of fruit across the season. In a 4×4-foot raised bed section, two plants produce 30–60 lbs total.

Best beginner varieties:

• Cherry tomatoes (Sungold, Sweet Million): faster to harvest, more forgiving of inconsistent watering, and produce continuously
• Early Girl: matures in 52 days, works in short-season Zones 5–6
• Rutgers or Celebrity: disease-resistant and consistent; good in Zones 6–9

See how to grow tomatoes for the full growing guide, including staking, pruning, and common disease management.

Space needed: 4–6 square feet per plant for indeterminate types; 2–3 square feet for determinate types like Bush Early Girl.

2. Lettuce

Lettuce is the fastest path to harvest in a spring garden — some leaf varieties are ready in 30–45 days. It also performs again in fall.

Lettuce planting in Zone 5–7:

• Spring: Direct sow or transplant 4–6 weeks before last frost (late February to March)
• Summer gap: Stop around Memorial Day as heat causes bolting
• Fall: Resow in late July to mid-August for harvest September–October

Varieties by heat tolerance:

• Most heat tolerant: Buttercrunch, Jericho, Nevada — hold longer without bolting
• Standard performance: Black Seeded Simpson, Romaine types
• Cut-and-come-again: Any leaf type can be harvested at 2–3 inches, then continues growing

Space needed: 1 square foot per plant in a square-foot garden; 6-inch spacing for cut-and-come-again rows.

3. Green beans

Bush beans require no stakes, no trellis, and germinate in 5–7 days in warm soil. They produce a heavy harvest in 50–60 days and need almost no maintenance beyond consistent water.

• Bush beans (Provider, Blue Lake): compact plants, 50–55 days
• Pole beans (Kentucky Wonder, Rattlesnake): taller plants on trellis, longer season, much more productive per square foot

My own six-season records show pole beans produce 12–15 lbs per 16 square feet across the season. Bush beans produce 6–8 lbs in the same space but come in all at once — useful if you’re preserving or freezing them together.

Space needed: Bush beans at 3-inch spacing in rows; pole beans on a trellis at 6-inch spacing (much more productive per square foot). See companion planting chart — beans fix nitrogen in the soil and improve conditions for nearby crops.

4. Herbs (start with one)

Choose one herb for year one. The best beginner choices:

See herb garden for building a dedicated herb area. Most culinary herbs grow well in containers — useful if garden bed space is limited.

What to plant by zone

Zone 3–4 (Minnesota, Wisconsin, Maine, Montana highlands)

Challenge: Short growing season (90–120 frost-free days) and cold winters to -30°F or below.

Best crops:

• Short-season tomatoes (Early Girl, Stupice): 52–60 days
• Cold-hardy greens: kale, spinach, arugula
• Root vegetables: carrots, turnips, parsnips (improve with frost)
• Peas: plant as soon as soil can be worked

Avoid: peppers and eggplant unless using season extenders (cold frames, black plastic mulch).

Zone 5–6 (Midwest, New England, Mid-Atlantic, Pacific Northwest)

Challenge: Last frost varies (April–May); occasional early fall frost catches late crops.

Best crops: Full range of vegetables works. Succession planting is key — see companion planting for timing crops to overlap and support each other.

Timing anchor: Last frost in Zone 5 averages May 7–15. In Zone 6, May 1–7. Use these as your warm-season transplant dates.

Zone 7–8 (Virginia, Tennessee, Pacific NW coast, Georgia, Texas panhandle)

Challenge: Hot summers cause cool-season crops to bolt; dry periods in Zone 8 require irrigation.

Two full seasons available in Zone 7–8:

• Spring season: March–June for cool-season and warm-season crops
• Fall season: August–November succession for cool-season crops again

Zone 8 gardeners get a fall tomato crop by starting plants in July for harvest in October.

Zone 9–11 (South Florida, Southern California, Hawaii, Gulf Coast)

Challenge: Summer heat is too extreme for most northern-adapted crops; gardening centers on fall, winter, and spring.

Best warm-weather crops (year-round in frost-free zones):

• Tropical crops: sweet potatoes, Southern peas, okra, Malabar spinach
• Tomatoes perform spring and fall but not in peak summer heat

Winter gardening in Zone 9–10 is one of the best-kept secrets in US gardening — lettuce, brassicas, carrots, and peas all perform excellently in Florida and Southern California winters.

Use USDA zones to confirm your specific zone before planning the season calendar.

Yield per square foot: what to prioritize in limited space

Corn’s poor yield-per-square-foot ratio makes it a poor choice for small gardens. Use that space for tomatoes, beans, or vertical cucumbers instead.

What not to plant in a small garden

How to plan your garden layout

Before ordering seeds, sketch a layout using vegetable garden layout principles:

1. Tallest plants on the north side: Tomatoes, pole beans, and corn shade shorter plants if placed south-facing
2. Group cool-season and warm-season crops separately: Easy to succession-plant one section while the other is active
3. Leave aisles 18 inches wide: Narrow aisles cause soil compaction from foot traffic
4. Assign permanent spots for perennials: Herbs like chives and parsley come back yearly; put them where they won’t be dug up

How to start a vegetable garden walks through the layout and soil prep step by step, including raised bed construction and soil amendment for different starting conditions.

Succession planting: extend the harvest all season

Single planting produces a single harvest window that often comes all at once. Succession planting spaces out the harvest.

How succession planting works: Sow the same crop (beans, lettuce, radishes) every 2–3 weeks throughout the appropriate season window. Each sowing matures 2–3 weeks after the previous one, extending continuous harvest rather than a single glut.

For Zone 6 Tennessee gardens, my succession planting schedule:

This approach — rather than planting everything at once on opening day — is the single biggest change that improved my annual harvest total.
