4×8 Raised Bed Garden Layout: 32 Squares, 12 Crops, With a Plan

A 4×8 raised bed is 32 square feet, the size I build most, and this layout fills it with twelve crops: one tomato on a 2×2 block, one square each of cucumbers and peas on a trellis along the north edge, three peppers, three kale, two squares of onions, three of bush beans, three of beets, three of carrots, three basil, three of lettuce and three of spinach. That is 1 tomato, 2 cucumbers, 8 peas, 3 peppers, 3 kale, 8 onions, 27 beans, 27 beets, 48 carrots, 3 basil, 12 lettuce and 27 spinach plants.

A 4x8 raised bed laid out in Plan My Garden with square foot spacing; each square shows the crop and how many plants fit.
The 4×8 bed as Plan My Garden laid it out for zip code 03301 (Concord, New Hampshire) for spring. North is at the top; the trellis icon marks crops that climb.

What goes in each square

Every number comes from the square foot gardening chart; the linked crop pages show the planting pattern for each square.

Why the crops sit where they do

Everything that climbs is on the north edge: the tomato block in the corner, then cucumbers and peas on a string trellis. That is the one rule in this bed I would not break, because a trellis on the south side shades half of what is behind it by August. The peppers and kale, the next tallest, sit in the row below. Roots and greens fill the southern half in threes, which is enough of each for a family to eat from without a glut.

Three squares of bush beans is a good number; nine would come in all at once. Three squares of carrots is 48 carrots, which sounds like a lot until you pull them at the size of a finger for the first thinning.

When to plant them, counted from your last frost

These are the windows the Plan My Garden planner uses for every crop in this bed, in weeks from your average last spring frost. Put your date into the seed starting calendar to turn them into dates, or let the planner do it from your zip code.

Make it your own

If you do not want a tomato block, four squares of cucumbers or pole beans on the trellis use the same space. Onions can go to four squares if you store them. In a hot climate, drop the peas and spinach and give the squares to peppers and basil.

Most of what is in this bed I grow from Wood Prairie Family Farm, a certified organic seed farm in Maine. Code PMG5 takes 5% off. Buying through that link supports this site at no cost to you.

Quick questions

How many plants fit in a 4×8 raised bed?

With square foot spacing, 32 squares hold anywhere from 32 large plants to 512 carrots. This mixed layout holds 169 plants across twelve crops, including 48 carrots, 27 beets and 27 spinach.

Which side of a 4×8 bed should the trellis go on?

The north side, so the tall crops shade the path and not the bed. If your bed runs east to west, the trellis goes along the long north edge; if it runs north to south, put it across the north end.

How many tomato plants fit in a 4×8 bed?

One per four squares unpruned, so up to eight if the whole bed is tomatoes. In a mixed bed like this one, a single 2×2 block on the north edge is plenty; pruned to one stem you can fit one per square along the trellis.
