Planning spring garden vegetables means matching cool-season crops — peas, lettuce, spinach, radishes, carrots, onions, potatoes and brassicas — to a well-laid-out bed with the right spacing, succession and crop rotation. A little layout planning before you sow turns a spring garden from a crowded scramble into a productive, low-disease space. This guide covers bed design, spacing by crop, interplanting, rotation, and zone timing with soil temperatures in °F, so the garden is set up to produce from early spring onward.

Laying out the spring beds
Good layout starts with sun and height. Site beds where they get at least six hours of direct sun, orient rows roughly north to south for even light, and place tall crops — peas on netting, staked supports — on the north side so they don't shade shorter neighbors. Keep beds no wider than about 4 feet so you can reach the center from either side without compacting the soil, and leave paths wide enough to kneel and harvest.
Group crops by how long they hold the bed. Quick cool-season crops that will be replaced after the last frost go in blocks you can clear and replant, while long-stay crops like onions and potatoes get their own dedicated space. This is the planning layer that the plant-now list in spring vegetables to plant sits on top of.
It helps to sketch the beds on paper or a simple grid before the season starts, marking not just what goes where but roughly when each crop will be pulled. A spring bed is rarely a single planting — it is a schedule. A block of early radishes might be followed by beans; a row of spring lettuce gives way to peppers; the pea trellis comes down in early summer and cucumbers climb it next. Drawing this out reveals conflicts before they happen, such as a slow crop blocking a bed you will need for a warm-season transplant, and it turns the vague intention to "grow a spring garden" into a concrete sequence you can actually follow. Keep the sketch and annotate it through the season; it becomes next year's rotation record.

Spacing spring vegetables correctly
Crowding is the most common cause of poor spring harvests — thin ruthlessly. These in-row spacings suit both rows and intensive grids.
| Crop | In-row spacing | Notes |
|---|---|---|
| Radishes | 1 inch | Fast; interplant with slow crops |
| Carrots, beets | 2 to 3 inches | Thin early to avoid tangling |
| Spinach | 3 to 4 inches | Closer for baby leaf |
| Lettuce | 6 to 10 inches | Wider for heads, closer for leaf |
| Onions | 4 inches | Closer if pulling as scallions |
| Broccoli, cabbage | 12 to 18 inches | Big plants need room |
Interplanting to use every inch
Pairing a quick crop with a slow one gets two harvests from one space. Classic spring combinations include radishes sown between rows of carrots or parsnips and pulled before the slower roots need the room, and leaf lettuce tucked around young broccoli or cabbage, filling the gaps until the big plants close in. Onions and carrots make traditional bed-mates because their tops and roots occupy different space. The rule is to combine crops that differ in speed, height or rooting depth so they draw on the bed at different times.
Interplanting also makes use of vertical layers, not just horizontal gaps. A trellis of peas casts light shade on its north side that suits lettuce or spinach, which appreciate a little protection as spring warms. Fast greens can be broadcast under a framework of caged tomatoes set out later, harvested before the tomatoes cast heavy shade. Even the edges of a bed earn their keep — a fringe of radishes or scallions along a path uses ground that would otherwise be trodden. The aim throughout is to keep every square foot doing something, so the garden's yield comes from clever layering rather than simply from more space. Done well, a modest bed interplanted this way outproduces a larger one sown in single, widely spaced rows.

Building crop rotation into the plan
Even a small garden benefits from moving families each year to limit disease and balance nutrients.
- Brassicas (broccoli, kale, cabbage) — heavy feeders; prone to clubroot if repeated.
- Nightshades (tomatoes, peppers, potatoes) — keep off ground that held them last year.
- Legumes (peas, beans) — fix nitrogen; good predecessors for leafy crops.
- Alliums (onions, garlic) — light feeders; fit between hungrier crops.
- Roots (carrots, beets) — rotate to avoid soil pests building up.
Sketch the beds and note what grew where each spring — it makes next year's rotation obvious.
The core spring garden crops
Spring gardens are built on frost-tolerant cool-season vegetables that go in before the last frost. See cool season vegetables for the full category.
| Crop | Soil temp to sow | Days to maturity |
|---|---|---|
| Peas | 40°F | 55 to 70 |
| Lettuce, spinach | 40 to 45°F | 30 to 50 |
| Radishes | 40°F | 25 to 30 |
| Carrots, beets | 45°F | 55 to 80 |
| Potatoes | 45°F | 70 to 100 |

Planning for succession
A spring garden is most productive when it is never idle. Sketch a plan that re-sows fast crops — lettuce, radishes, spinach — every 2 to 3 weeks, and pencils in the warm-season crops that will take over each bed after the last frost. Designing this hand-off into the layout from the start means beds flow from cool-season to warm-season crops without a gap, and you avoid the mid-spring realization that everything ripened at once. The seasonal sowing dates are laid out in what to plant in spring.
Zone timing for the spring garden
| USDA zone | Start cool-season crops |
|---|---|
| 3 to 4 | April to early May |
| 5 to 6 | March to April |
| 7 | February to March |
| 8 | January to February |
| 9 to 10 | Finish before spring heat |
Spring garden planning tips
- Design before you dig — a sketch prevents crowding and wasted space.
- Tall crops on the north side so they don't shade the rest.
- Space for the mature plant, not the seedling — then thin without mercy.
- Interplant quick and slow crops to double up on space.
- Plan the warm-season hand-off so beds never sit empty.
