Pole bean (Phaseolus vulgaris). Most gardening advice treats pole beans as a pretty trellis crop that gives you a handful of green beans for dinner. That’s true, but it’s also selling them short. Grown the right way — and left on the vine a little longer than you’re used to — pole beans turn into one of the best calorie-dense, shelf-stable protein crops you can fit into a backyard. Pole bean are more drought tolerant than bush beans. Pole beans usually yield more than bush beans as they are larger plants and can produce more beans in the space given space. A 10-foot row of pole beans can yield approximately 8 pounds, while the same length of bush beans would likely yield only 4 to 5 pounds.

The difference comes down to one decision: are you picking them green, or letting them dry?

I’ve been growing pole beans in the Pacific NW since the 1980’s. I especially love how they have an extra rich flavor and how space saving they are. I have tried many different varieties and have evaluated them for flavor, productivity and reliability

Green Beans vs. Dry Beans: Two Very Different Crops From the Same Plant

Picked young, pole beans are a snap bean — crisp, mild, great fresh or blanched and frozen. Nutritionally, they’re solid but not calorie-dense: mostly water, fiber, and vitamins A, C, and K, with only around 30-35 calories per cup.

Left on the vine until the pods dry out and rattle, the same plant gives you a dry bean — a completely different food. Dry beans run roughly 1,550-1,600 calories per pound, are 21-25% protein by weight, and store for years in a sealed container without refrigeration. That’s the version that actually matters if your goal is calories and food security, not just fresh eating.

If you’ve only ever grown pole beans for the table, this is the mental shift: the real harvest happens after the plant looks done.

How Much Can You Actually Expect to Grow?

Numbers vary a lot by variety, soil, and season, but here’s a realistic range pulled from extension data and experienced growers, not marketing copy:

• Fresh pods: roughly 8 lbs of green beans per 10-foot row (24-40 plants), according to University of Florida extension data — some growers report up to 3-7 lbs per single well-tended plant over a full season.
• Dry beans: figure roughly 3/4 lb to 1 lb of dry beans per plant in a decent year. That’s lower than the fresh-pod weight because you’re losing all the water weight and the pod itself — but it’s the number that actually matters for calories.

So a modest planting of, say, 15-20 pole bean plants on a couple of trellises could realistically give you 10-20 lbs of dry beans in a season — that’s 15,000-32,000 calories of shelf-stable food from a space that might be 30-40 square feet. Compare that to the same footprint growing lettuce, and it’s not close.

Best Varieties If You’re Growing for Dry Beans, Not Just Fresh Eating

Not every pole bean variety is worth drying — some are bred purely for tender fresh pods and give you scrawny, low-yield seeds if you let them mature. A few that are genuinely good dual-purpose or dry-bean performers:

• Kentucky Wonder — the classic all-rounder. Good fresh, and the pods fill out well if you leave them to dry.
• Rattlesnake — heat- and drought-tolerant, purple-streaked pods, holds up well left on the vine to dry.
• Cherokee Trail of Tears — an heirloom specifically prized for drying; dark, glossy beans with good flavor cooked.
• Kwintus — very early delicious variety, reliable here in the Pacific NW. Will produce a large amount of big dried seeds.
• Runner Beans (Phaseolus coccineus) — technically a different species, but grown the same way; the dried beans are large and starchy, and the plant doubles as an ornamental with its ornamental flowers. Scarlet Runner and Painted Lady are two of the most reliable.

Growing Them: The Short Version

Pole beans want warmth, sun, and something to climb:

• Plant after your last frost, once soil hits about 60°F.
• Space seeds 3-5 inches apart along a sturdy trellis, teepee, or fence — anything 6-8 feet tall.
• They’re light feeders. Too much nitrogen gives you a jungle of vines and fewer pods — go easy on fertilizer.
• Water consistently, especially once flowering starts; inconsistent watering is the most common reason for poor pod set.

If you’re growing for fresh eating, pick every few days to keep production going. If you’re growing for dry beans, you do the opposite — pick less, and let a section of the vine run its full course. Most gardeners split the difference: harvest some pods young for the table, and deliberately leave a portion of the vine alone to mature and dry.

Drying and Storing: Turning the Harvest Into Actual Food Storage

Once pods are dry, brittle, and rattle when shaken, pull the whole plant or strip the pods. From there:

1. Shell the beans — by hand for small batches, or the old trick of stuffing dried pods into a pillowcase or burlap sack and stomping/flailing them, then winnowing out the chaff.
2. Finish drying indoors for a week or two on a screen or tray, out of direct sun, to make sure there’s no residual moisture before storage.
3. Store in an airtight container — mason jars, food-grade buckets with gasket lids, or vacuum-sealed bags. Kept cool, dark, and dry, dry beans stored this way will keep for several years without meaningful nutrition loss.

That last point is really the whole pitch: unlike almost anything else you grow in a backyard garden, dry beans don’t need a freezer, a root cellar, or a canning setup to store long-term. A jar in a closet does the job.

The Bottom Line

If you’re gardening purely for fresh vegetables, pick pole beans young and often. But if part of your goal is actually putting calories away — whether that’s cutting the grocery bill or building real food security — treat at least part of your pole bean patch as a dry bean crop. Same seed packet, same trellis, completely different payoff.

I think pole bean are a great crop to grow considering how space saving and delicious they are. Truly a staple for food self-sufficiency
