A 4×8 raised bed gives you 32 square feet of growing space. That sounds small until you start planning properly — in a single season, a well-planned 4×8 can produce 60 or more pounds of vegetables. Over a full year with seasonal rotation, some gardeners push past 100 pounds from this single bed. The key is knowing exactly what fits, how to space it, and when to transition between seasons.
Every layout below uses intensive spacing (tighter than traditional row gardening, based on the square foot gardening method) and assumes a bed that is at least 10 to 12 inches deep with quality soil. If your bed is shallower, check our depth guide to understand which crops need more room below ground. For soil mix recommendations, our soil mix guide has the formula.
Spring Layout: Tomatoes, Peppers, and Herbs
This is the classic warm-season arrangement that maximizes your most valuable crops. Plant after your last frost date.
The Layout (4×8, divided into sections)
| Row (2 ft wide) | Plants | Spacing | Count |
|---|---|---|---|
| Back row (north side) | Indeterminate tomatoes on cages or stakes | 24 inches apart | 4 plants |
| Middle row | Bell peppers and hot peppers | 18 inches apart | 5 plants |
| Front row (south side) | Basil, parsley, and marigolds | 12 inches apart | 8 plants |
Why This Works
Tall tomatoes go on the north side so they do not shade shorter crops. Peppers fill the middle at 18-inch spacing — tight enough for full canopy coverage that shades out weeds but open enough for air circulation. Basil in the front row is the classic tomato companion: it attracts pollinators, repels certain pests, and you will use it in the kitchen alongside the tomatoes anyway. Marigolds at the corners deter nematodes and whiteflies.
Expected yield from this layout: 40 to 60 pounds of tomatoes, 15 to 25 pounds of peppers, and several cuttings of basil per week throughout summer. See our companion planting chart for more pairing ideas.
Summer Layout: Squash, Beans, and Vertical Cucumbers
This layout is for a second bed or for gardeners who want variety beyond tomatoes and peppers. It uses vertical space aggressively.
The Layout
| Section | Plants | Spacing | Count |
|---|---|---|---|
| North half — trellis on back edge (4×4 area) | Cucumbers trained vertically on a 5–6 ft trellis | 12 inches apart along trellis | 4 plants |
| North half — in front of trellis (4×2 area) | Bush beans (Provider or Contender) | 6 inches apart, 3 rows | 24 plants |
| South half (4×4 area) | Summer squash or zucchini | 24 inches apart, centered | 2 plants |
| South corners | Nasturtiums or dill (pollinator attractors) | — | 4 plants |
Key Details
Cucumbers on a trellis use 1 foot of bed width but grow 5 to 6 feet tall — you get the production of a 4×4 sprawling area in a 4×1 footprint. Bush beans fix nitrogen in the soil, benefiting neighboring crops. Two summer squash plants are all you need — each one can produce 20 to 30 fruits over the season. Seriously, two is enough. Plant a third only if you want to supply the entire neighborhood.
Succession-sow the beans every 3 weeks for continuous harvest. When the first sowing is spent (about 6 weeks), pull it and resow. You can get 3 rounds of beans from the same space in one season.
Fall Layout: Greens, Root Vegetables, and Garlic
As summer crops finish, transition the bed for fall and winter production. In most zones, plant this layout 8 to 10 weeks before your first frost.
The Layout
| Section | Plants | Spacing | Count |
|---|---|---|---|
| North third (4×2.5 area) | Kale and collards | 18 inches apart | 4 plants |
| Middle third (4×2.5 area) | Lettuce mix and spinach | 6 inches apart (broadcast sow) | 30+ plants |
| South third — left half | Carrots and beets | 3 inches (carrots), 4 inches (beets) | 40 carrots, 16 beets |
| South third — right half | Garlic (plant 4–6 weeks before ground freezes) | 6 inches apart, 2 rows | 12 cloves |
Why This Works
Kale and collards go north because they are the tallest fall crops — up to 24 inches. They tolerate frost and actually taste better after cold exposure. The middle section is a cut-and-come-again lettuce and spinach bed: broadcast seed, cut at 4 inches tall with scissors, and it regrows 2 to 3 times. That middle strip alone can produce salad greens for a family of four for 8 to 12 weeks.
Root vegetables in the south get full sun and mature underground where soil stays warmer than air temperature. Garlic goes in last (October or November in most zones) and overwinters for harvest the following summer — it occupies the space through spring when you will want those squares for warm-season crops again, so plan accordingly.
Year-Round Rotation Strategy
The real power of a 4×8 bed comes from rotating through all three layouts each year. Here is the annual sequence:
- Spring (after last frost): Plant the warm-season layout (tomatoes, peppers, herbs). Harvest June through September.
- Late summer transition (August): As tomato production slows, start fall seedlings in trays. When you pull spent summer crops, compost them and add 1 to 2 inches of fresh compost to the bed.
- Fall (8–10 weeks before first frost): Plant the cool-season layout (greens, roots, garlic). Harvest October through January (longer with row covers).
- Late winter transition (February–March): Pull finished cool-season crops (except garlic if overwintering). Add compost again. Start summer seedlings indoors.
This rotation keeps the bed productive 10 to 12 months per year and naturally breaks pest and disease cycles by alternating crop families. Each compost addition replaces the nutrients the previous crop used. Our raised bed guide covers long-term soil maintenance in detail.
Spacing Quick-Reference for 4×8 Beds
How many of each plant fit in 32 square feet? This chart gives you intensive spacing counts:
| Crop | Spacing | Plants per 4×8 (full bed) |
|---|---|---|
| Tomatoes (indeterminate) | 24 inches | 6 |
| Tomatoes (determinate) | 18 inches | 9 |
| Peppers | 18 inches | 9 |
| Cucumbers (trellised) | 12 inches | 8 |
| Bush beans | 6 inches | 72 |
| Lettuce | 6 inches | 72 |
| Carrots | 3 inches | 200+ |
| Radishes | 2 inches | 400+ |
| Kale / collards | 18 inches | 9 |
| Squash / zucchini | 24 inches | 4–5 |
| Garlic | 6 inches | 72 |
These are intensive counts if you fill the entire bed with one crop. Most gardeners mix crops, so use the per-row or per-section counts from the layouts above for practical planning.

Frequently Asked Questions
How many tomato plants fit in a 4×8 raised bed?
Four indeterminate tomatoes (24-inch spacing) with room for companion herbs in front, or six if you fill the entire bed with tomatoes only. Do not crowd more than six — indeterminate tomatoes need air circulation to prevent disease, and overpacked beds produce less fruit per plant. For variety recommendations, see our best tomatoes for raised beds.
Can I grow everything I need in one 4×8 bed?
For one or two people eating seasonally, one 4×8 provides a meaningful portion of your fresh vegetables — especially salad greens, herbs, tomatoes, and peppers. For a family of four, two or three 4×8 beds plus some vertical growing provides genuine food security during the growing season. Start with one bed and add more once you know your workflow.
What is the minimum depth for a 4×8 raised bed?
10 to 12 inches for most crops. Tomatoes, peppers, and root vegetables prefer 12 to 18 inches. If your bed is only 6 inches deep, you are limited to shallow-rooted crops like lettuce, herbs, radishes, and bush beans. Our depth guide has specific recommendations for every common vegetable.
Do I need to rotate crops in a single raised bed?
Yes. Planting tomatoes in the same spot year after year builds up soilborne diseases (early blight, fusarium wilt) and depletes specific nutrients. Rotate by family: nightshades (tomatoes, peppers) one year, legumes (beans, peas) the next, brassicas (kale, broccoli) the third. If you have only one bed, rotate within the bed by shifting crop families to different sections each year.
Should I use square foot gardening spacing or traditional row spacing?
Square foot gardening (intensive) spacing in a raised bed. Traditional row spacing was designed for mechanical cultivation between rows — in a raised bed, you never walk in the growing area, so you can pack plants much tighter. The per-plant yield drops slightly at intensive spacing, but the per-square-foot yield increases dramatically.
