How Many Bean and Pea Plants Per Person?
Beans and peas trip people up because each plant gives so little. A single bush bean is under a pound, a shelling pea plant is a quarter pound of actual peas, so the counts run much higher than tomatoes or squash. Here are honest per-person numbers for bush beans, pole beans, snap peas, shelling peas, and edamame, plus how to plant so you are not shelling for an hour to fill a bowl.

The short answer, per person
Legumes are low-yield per plant, so plan on more of them. These counts are per person:
- Bush beans, fresh eating: 10 to 15 plants. Each gives about 0.75 lb in one 3-week flush.
- Bush or pole beans to can and freeze: 30 to 40 plants per person for a winter supply.
- Pole beans, a steady summer supply: 6 to 8 plants. Each gives about 1.5 lb over 8 weeks.
- Snap peas, fresh snacking: 20 to 30 plants. Each gives only about 0.4 lb.
- Shelling (English) peas: 40 or more plants for a meaningful bowl. Each gives just 0.25 lb of shelled peas.
- Edamame: 20 to 30 plants for a few meals. Each gives about 0.35 lb, all at once.
Bush beans come all at once, pole beans keep giving
A bush bean plant yields about 0.75 pound, but it hands most of it over in a single 3-week burst, then it is done. That is great for a big batch to can or freeze. To keep eating fresh all summer, sow a new short row every 2 weeks.
A pole bean plant yields about 1.5 pounds, twice a bush bean, and it does it over roughly 8 weeks up a trellis. So 6 to 8 pole plants per person keep a steady handful coming for dinner without any succession sowing. Pick both every 2 to 3 days while the pods are slim.
Peas need patience, and a lot of plants
Peas are the biggest surprise. A snap pea plant gives about 0.4 pound of whole edible pods, so you need 20 to 30 plants per person just for fresh snacking over their short 3-week spring window.
Shelling peas are worse per plant: about 0.25 pound of actual shelled peas, since you throw the pod away. To put up a few bags of peas you need 40 or more plants. That is the honest math, and it is why home gardeners often grow snap peas (eat the whole pod) instead of shelling types.
Edamame is a one-shot harvest
Edamame gives about 0.35 pound per plant and, unlike snap beans, it ripens all at once and you pick the whole plant. So 20 to 30 plants per person gives a few meals, and it freezes well after a quick blanch. Sow a second batch 2 weeks later if you want two harvests instead of one big one.
Because beans and peas fix their own nitrogen, they are light feeders and easy to fit around the garden. The catch is always the plant count, not the care.
Space them close and go vertical
Beans and peas pack in tight. Bush beans go 3 inches apart in rows 18 inches apart. Snap and shelling peas go 2 inches apart. Pole beans go 6 inches apart at the base of a 6-foot trellis. Growing pole beans and peas up a trellis is how you fit high plant counts into a small bed.
Get your exact number
With legumes the count really matters, because guessing low means one dinner's worth. The planner asks how often you eat beans and peas and whether you want to preserve any, then computes the exact plant count and the trellis space, so you plant 45 beans, not a vague row.

Questions, answered straight
About 10 to 15 bush bean plants per person for fresh eating, since each gives only about 0.75 lb in one 3-week flush. For canning or freezing a winter supply, plan on 30 to 40 plants per person. Pole beans yield about 1.5 lb each over 8 weeks, so 6 to 8 keep one person in fresh beans all summer.
More than you would guess. Snap peas give about 0.4 lb per plant, so 20 to 30 plants per person for fresh snacking. Shelling peas give only about 0.25 lb of shelled peas each, so you need 40 or more plants for a real bowl. Many gardeners grow snap peas instead so nothing is thrown away.
Bush beans give one big 3-week flush, ideal for a batch to freeze or can. Pole beans yield twice as much per plant over about 8 weeks up a trellis, better for a steady fresh supply. Many gardens grow both.
Bush beans go 3 inches apart in rows 18 inches apart, so 60 plants fit in one 4 by 8 bed. Pole beans go 6 inches apart up a 6-foot trellis, which fits high counts into little ground space.
