How Many Bean Plants per Square Foot?
9 bush beans per square foot, in a 3 x 3 grid 4 inches apart. Pole beans climb, so they go 8 per square around a pole or along a trellis and use the air instead of the ground.
The spacing pattern
| Square foot method | 9 per square: a 3 x 3 grid, 4 inches apart. Pole beans: 8 per square around a pole or along a trellis |
|---|---|
| 4 x 4 bed (16 squares) | 144 bush bean plants |
| 4 x 8 bed (32 squares) | 288 bush bean plants |
Beans are small, upright plants with shallow roots, and they fix their own nitrogen, so they do not mind close company. Nine per square is dense enough that the plants hold each other up and shade out weeds, and a square yields a real handful every picking.
Planting the square
- Wait for soil above 60°F; beans rot in cold ground.
- Coat the seed with inoculant, then sow one seed at each point of a 3 x 3 grid, an inch deep.
- Sow a new square every three weeks for a continuous harvest, and pick every two days once they start.
Tim’s growing notes
Everything I do for a big bean harvest, the Provider variety, inoculant, succession plantings and a fence to keep the plants from flopping, is in How to Grow Bush Beans. For a heirloom I like, see the Celine bean.
Soil temperature for germination
From my Seed Germination Temperature Chart: bush beans germinate from 60°F, do best at 75-85°F, and stop above 95°F.
Days for seedlings to emerge at different soil temperatures, from the same chart:
| Soil temperature | Days to emerge |
|---|---|
| 59°F | 16 days |
| 68°F | 11 days |
| 77°F | 8 days |
| 86°F | 6 days |
When to plant beans
These are the windows the Plan My Garden planner uses, counted from your average last spring frost. Enter your frost date on the seed starting calendar to turn them into dates. Beans are sown direct once the soil is above 60°F; pole beans take about 65 days.
| Direct sow | 1 week after to 3 weeks after your last frost |
|---|---|
| Days to maturity | about 60 days |
How I grow them, in brief
Provider is my bush bean: easy, heavy yielding, and it germinates in cooler soil than most, which matters in New England. I wait for a soil thermometer to read 60°F, add compost to the top of the bed, and sow nine per square an inch deep, after swirling the seed in a jar with inoculant and a splash of water so the roots get the nitrogen-fixing bacteria from day one. Overhead water until they germinate, then drip only, and mulch with grass clippings. A low fence around the bed keeps the loaded plants from flopping over the edge. I sow a new square every three weeks, three plantings, and pick at 4 to 7 inches, a little fatter than a pencil. At season end I cut the plants at the soil line and leave the roots. Everything, including a look at the root nodules, is in How to Grow Bush Beans.
Where I get seed
Wood Prairie’s organic beans include Celine, Jade, Gold Rush wax and Early Riser. Code PMG5 takes 5 percent off.
Quick questions
Bush beans or pole beans for a small bed?
Pole beans give more per square over the season because they keep producing; bush beans give a big flush fast and then you replant. I grow bush beans in succession.
How many beans in a 4 x 8 bed?
288 at 9 per square, which is a lot of beans. Four to eight squares per planting is plenty.
Let the planner place them
Plan My Garden is free to start: draw your beds, pick bush beans and everything else you want to grow, and it places each plant at the right spacing and gives you a planting schedule for your zip code.
