How to Grow Beans in Your Garden
Beans are among the easiest crops you can grow. Plant them after the last frost in well-draining soil with full sun. Bush beans produce all at once for canning, while pole beans climb and give you pickings all season long. They're ready in 50-70 days, and they'll actually improve your soil while they grow.
- Difficulty: Easy
Step by step
- Choose your bean type. Bush beans stay compact and produce their whole crop within two weeks — perfect if you want to preserve them. Pole beans climb 6-8 feet and keep producing until frost kills them. Pick bush varieties like Provider or Cherokee Trail of Tears. For pole beans, try Kentucky Blue or Romano Italian.
- Wait for the right planting time. Beans hate cold soil. Plant two weeks after your last frost date when soil temperature hits 60°F. If you plant too early, the seeds will rot in cold, wet ground. In most places, this means late May or early June.
- Prepare the planting area. Pick a spot with 6-8 hours of direct sunlight. Beans aren't picky about soil, but they need drainage. If water pools after rain, build raised rows or add compost to improve drainage. Don't add nitrogen fertilizer — beans make their own.
- Plant the seeds. Plant beans 1 inch deep and 3-4 inches apart. For bush beans, make rows 2 feet apart. For pole beans, plant them 6 inches apart at the base of a trellis, fence, or teepee of poles. Water gently after planting, then leave them alone until they sprout.
- Set up support for pole beans. Put your trellis or poles in place before planting or right after. Beans will grab onto anything — wire mesh, bamboo poles, even corn stalks. Make sure supports are 6-8 feet tall and anchored well. The vines get heavy when loaded with pods.
- Water consistently but don't overdo it. Give them about an inch of water per week, including rainfall. Water at soil level to keep the leaves dry and prevent disease. Once pods start forming, keep the soil consistently moist but never soggy. Drought-stressed plants drop their flowers.
- Harvest at the right stage. For fresh eating, pick pods when they snap cleanly and the beans inside are small and tender. For shell beans, wait until pods are plump but still green. For dry beans, leave pods on the plant until they rattle when shaken, then harvest before they split open.
Tips & troubleshooting
- Never work around bean plants when they're wet — this spreads bacterial diseases
- Mulch around plants once they're 4 inches tall to conserve moisture and suppress weeds
- Pick beans every few days to keep plants producing — leaving mature pods signals the plant to stop flowering
- Save some pods for seed by letting them dry completely on the plant, then store in a cool, dry place
- Rotate bean locations each year to prevent soil-borne diseases from building up
Variations
- Successive planting. Plant bush beans every two weeks through midsummer for continuous harvests. Stop planting 10 weeks before your first expected frost.
- Container growing. Bush beans work well in containers at least 12 inches deep. Use a container that holds 5 gallons minimum for a decent harvest.
- Three Sisters planting. Plant pole beans with corn and squash in the traditional Native American method. The corn provides the pole, beans add nitrogen, and squash shades the soil.
- Fall crop. In areas with long growing seasons, plant a second crop of bush beans in late summer, 10-12 weeks before the first frost date.
Questions
- Why aren't my bean plants flowering?
- Too much nitrogen makes beans grow lots of leaves but few flowers. Beans fix their own nitrogen, so they don't need fertilizer. High temperatures above 90°F also prevent flowering — provide afternoon shade in hot climates.
- What's eating holes in my bean leaves?
- Mexican bean beetles are the most common culprit. They're copper-colored with black spots and their yellow larvae eat leaves from underneath. Remove them by hand or use row covers until plants flower.
- Can I plant store-bought dried beans?
- Sometimes, but seed beans work better. Store beans are often treated to prevent sprouting, and you don't know their variety or growing requirements. Stick with seeds from reputable suppliers for reliable results.
- How do I know when dry beans are ready?
- The pods turn brown and papery, and you can hear the beans rattle inside when you shake them. Harvest before the pods split open and scatter the beans. If rain threatens, pull the whole plant and hang it to finish drying.
- Why are my bean seedlings dying?
- Cold, wet soil is usually the problem. Bean seeds rot if planted too early or if the soil doesn't drain well. Cutworms can also chew through young stems at soil level — check for the gray caterpillars hiding in the soil during the day.
