Raised Bed Garden Layout: Plans, Spacing & Plant Placement for Every Size

A raised bed without a plan is just a box of dirt. The difference between a productive raised bed and a disappointing one usually comes down to layout — what goes where, how close together, and in what order.

Here’s how to design a raised bed layout that maximizes yield, minimizes problems, and actually looks good.

Why Layout Matters

Random planting leads to:

• Overcrowding: plants competing for light, water, and nutrients
• Poor pollination: corn planted in a single row won’t pollinate
• Wasted space: gaps where fast crops could have grown between slow ones
• Disease: poor airflow from dense, unplanned planting

A good layout solves all of these.

The 4x4 Raised Bed (16 square feet)

The most popular beginner bed. Enough for a meaningful garden, small enough to reach the center from any side.

Beginner Layout: Salad Garden

└──────┴──────┴──────┴──────┘

Plant count: 4 lettuce, 4 radish, 2 cherry tomatoes (caged), 2 cucumbers (trellised on north side), 2 peppers, 4 spinach, 1 basil, 1 chives, 4 green onions

Yield estimate: 15-20 salads worth of greens, 50+ cherry tomatoes, 20+ cucumbers, 15+ peppers

└──────┴──────┴──────┴──────┘

Key: Tall plants (tomatoes, beans) on the north side so they don’t shade shorter plants.

The 4x8 Raised Bed (32 square feet)

The workhorse. Enough space for a real vegetable garden with room for succession planting.

South side (front)

Why this works:

• Tall crops along the north edge — tomatoes, pole beans, and trellised cucumbers don’t shade anything
• Herbs between vegetables — basil with tomatoes, dill near cucumbers (companion planting)
• Fast crops in front — radishes and lettuce are harvested in 30 days, making room for a second planting
• Marigolds in the corner — deter aphids and nematodes

Spacing Rules of Thumb

Forget memorizing spacing charts. Here are the patterns:

Plant Size	Spacing	Examples
Large	18-24” (1 per sq ft)	Tomato, pepper, eggplant, broccoli
Medium	12” (1 per sq ft)	Kale, Swiss chard, cabbage
Small	6” (4 per sq ft)	Lettuce, spinach, beets
Tiny	3” (9-16 per sq ft)	Radish, carrots, green onions
Vining	12” on trellis	Cucumber, beans, peas

The key insight: These are closer than row-garden spacing because raised beds have better soil. You’re not leaving room for a tractor — you’re optimizing for yield per square foot.

Succession Planting: The Layout Secret Weapon

The biggest mistake raised bed gardeners make is planting everything once. Succession planting turns a 4x8 bed into a production machine:

1. March/April: Plant lettuce, spinach, radishes, peas in the front rows
2. May (after those harvest): Replace with beans, second round of lettuce
3. June (after peas finish): Plant fall broccoli or kale starts
4. July: Direct sow fall carrots and beets where spring crops were
5. September: Plant garlic in empty spaces for next year

One 4x8 bed can produce 3-4 harvests per season with this approach.

Companion Planting in Raised Beds

In tight raised bed quarters, companions matter more:

Great neighbors:

• Tomatoes + basil (pest deterrent + flavor)
• Carrots + onions (mutual pest confusion)
• Beans + corn + squash (the Three Sisters)
• Lettuce + taller plants (natural shade)

Keep apart:

• Tomatoes + brassicas (nutrient competition)
• Beans + onions/garlic (sulfur inhibits nitrogen fixing)
• Fennel + everything (allelopathic)

Common Layout Mistakes

1. Planting tall crops on the south side — they shade everything behind them
2. Ignoring vertical space — a $10 trellis doubles your growing area for cucumbers, beans, and peas
3. No path plan — if you can’t reach it, you won’t weed it. Never make a bed wider than 4 feet
4. Same layout every year — rotate families annually. Tomatoes where beans were. Brassicas where nightshades were.
5. Forgetting succession — one planting per season wastes 60% of your bed’s potential

Track Your Layout Digitally

Drawing garden layouts on paper works until you want to compare this year’s plan to last year’s results. That’s where tracking software pays off — you can see which layout produced more tomatoes, which spacing worked better, and what companions actually helped.

Check your zone’s planting dates to plan your layout timing:

• Zone 5 Planting Calendar
• Zone 6 Planting Calendar
• Zone 7 Planting Calendar
