Planting, Growing, and Harvesting Green Beans

Catherine Boeckmann

Growing green beans is so easy that they are often the first vegetable children learn how to grow! All green beans are incredibly productive, even in containers. Here’s how to plant, grow, and harvest green beans, and learn the upsides and downsides of bush versus pole varieties.

About Green Beans

All green beans (also called 鈥渟tring beans鈥 or 鈥渟nap beans鈥) are tender annuals. Though most green beans are indeed green, they also come in purple, red, yellow, and streaked varieties.

What’s the Difference Between Bush Beans and Pole Beans?

The main difference between the many types of green beans is whether their growing style is classified as 鈥渂ush鈥 or 鈥減ole.鈥

  • Bush beans grow compactly (reaching about two feet tall) and do not require extra support from a structure like a trellis. 
  • Pole beans, aka climbing beans, grow as climbing vines that may reach 10 to 15 feet tall and require a trellis or staking. Watch this video to learn how to support beans properly.

There are pros and cons to both types, of course:

  • Bush beans generally require less maintenance due to their size, but pole beans typically yield more beans for longer and are mostly disease-resistant.
  • Bush beans produce in veggies about 50 to 55 days; pole beans will take 55 to 65 days. 
  • Bush beans often come in all at once, so stagger your plantings every two weeks to get a continuous harvest. Pole beans need their vines to grow and will produce for a month or two if you keep harvesting.

Planting

Beans grow best in well-draining soil with normal fertility and an acidic to neutral pH (6.0鈥7.0). They don鈥檛 typically need supplemental fertilizer because they fix their own nitrogen in the soil. However, particularly poor soil should still be amended with aged manure or compost in the fall prior to planting (or about a week before planting in the spring). 

Beans don鈥檛 like having their roots disturbed, so set up any supports for pole beans prior to planting. 

When to Plant Beans

  • Beans grow best when direct-seeded outdoors. Sow any time after the last spring frost date, when the soil has warmed to at least 55掳F (12掳C). Don鈥檛 plant too early, as cold, moist soil will delay germination and could cause the seeds to rot.
    • Tip: To get a head start on planting, place black plastic or landscaping fabric over your garden beds to warm the soil prior to sowing seeds.
  • Do not start green bean seeds indoors. Due to their fragile roots, they may not survive transplanting. Plus, they鈥檙e such fast growers that there鈥檚 no real advantage to starting them early indoors.

How to Plant Beans

  • Sow bush beans 1 inch deep and 2 inches apart in rows 18 inches apart.
  • Sow pole beans 1 inch deep, placing them around supports.
    • Tip: Plant pole and bush beans a little deeper in sandy soils, but not too deep. Seedlings cannot push through soil that is too deep, heavy, dense, packed, and/or mulched; they will break their 鈥渘ecks鈥 in trying to emerge.
  • For pole beans, set up trellises, stakes, or other supports prior to planting so that the plants鈥 fragile roots are not disturbed.
    • One option is to create a teepee: Tie three or four (or more) 7-foot-long bamboo poles or long, straight branches together at the top and splay the legs in a circle. Then, plant three or four seeds around each pole. As vines appear, train them to wind up the poles. For more stability, wrap string/wire around the poles about halfway up, encircling the tepee; this gives the vines something to grab.
    • Another easy support for them is a 鈥渃attle panel鈥濃攁 portable section of wire fence鈥16 feet long and 5 feet tall. The beans will climb with ease, and you won鈥檛 have to get into contorted positions to pick them. 
  • For a continued harvest that lasts all summer, sow seeds every 2 weeks. If you鈥檙e going to be away and unable to harvest, skip a planting. Beans do not wait for anyone!
  • Practice crop rotation (planting crops in different areas each year) to avoid the build-up of pests and diseases in one spot.

How to Grow Beans From Planting to Harvest

Growing

  • Mulch soil around bean plants to retain moisture; make sure that it is well-drained. Beans have shallow roots, so mulch keeps them cool.
  • Water regularly, about 2 inches per square foot per week. If you do not keep beans well watered, they will stop flowering. Water on sunny days so that foliage will not remain soaked, which could encourage disease.
  • If necessary, begin fertilizing after heavy bloom and the set of pods. Avoid using high-nitrogen fertilizer, or you will get lush foliage and few beans. A side dressing of compost or aged manure halfway through the growing season is a good alternative to liquid fertilizer.
  • Weed diligently but carefully to avoid disturbing the beans鈥 roots.
  • Pinch off the tops of pole bean vines when they reach the top of the support. This will force them to put energy into producing more pods instead.
  • In high heat, use row covers over young plants; hot weather can cause blossoms to drop from plants, reducing the harvest.

Growing Green Beans in Containers

You can also grow green beans in containers! An 8-inch-deep, 8-inch-wide container will hold one bush plant, while a 5-gallon pot will hold up to three bush or pole plants. For pole beans, plan to provide support in or immediately outside of the container. Fill the container with potting mix and rich compost. 

Beans grow best when direct-seeded (not transplanted) into the soil, whether it鈥檚 in a container or the ground. After all danger of frost has passed, sow into warm (55掳F or higher), moist soil. Put two beans into each hole between 1 and 11鈦2 inches deep. Eliminate the weaker one after germination by cutting the stem. (Do not allow two plants to coexist in one hole; neither will thrive.)

To care for your container of green beans, provide 6 to 8 hours of sun per day. Whenever the soil is dry, water to a depth of 1 to 2 inches. Fertilize with a low-nitrogen formula (5-10-10) diluted to half-strength to avoid excess foliage growth. Apply at planting time and when plants begin to flower.

Types

When it comes to green beans, the options are endless. Here are several types and varieties to consider:

  • Chinese (aka Asian) long beans (aka yardlong or asparagus beans): slender, 1- to 2-foot pods. Try 鈥極rient Wonder,鈥 鈥楻ed Noodle,鈥 or 鈥榊ardlong.鈥 All pole.
  • French green beans (aka filet or haricots verts): thin, tender, 3- to 5-inch pods. Try 鈥楥alima,鈥 鈥楳asai,鈥 or 鈥楳axibel鈥; in a container, plant 鈥楳ascotte.鈥 All bush.
  • Italian/Romano: wide, flat 6- to 8-inch pods even in the hottest summers. Try 鈥楨arly Bush Italian,鈥 extra-large-pod 鈥楯umbo,鈥 or 鈥楻oma II.鈥 All bush.
  • Purple beans: 5- to 6-inch pods are deep purple when raw and turn green when cooked. Try 鈥楢methyst,鈥 鈥楻oyal Burgundy,鈥 or 鈥榁elour.鈥 All bush.
  • Snap beans (aka string or stringless): slender, 5- to 7-inch pods. Try 鈥楤lue Lake 274鈥 (bush), heirloom 鈥楰entucky Wonder鈥 (bush or pole), or 鈥楶rovider鈥 (bush).
  • Yellow wax beans: 5- to 7-inch pods have a milder flavor than green varieties. Try stringless 鈥楥herokee鈥 (bush), classic 鈥楪olden Wax鈥 (bush), or 鈥楳onte Gusto鈥 (pole).

If you are planting your green beans in containers, we suggest bush or pole beans. Many compact varieties are available, and many standard beans can be grown in containers as well. Here are some of our favorite bean varieties for containers.

  • Phaseolus lunatus 鈥榃hite Dixie Butterpea鈥: 16 to 24 inches tall; three to four small lima beans per pod; excellent for hot weather climates.
  • P. vulgaris 鈥楧erby鈥: tender, round, 7-inch-long pods form on 18-inch plants; resistant to bean common mosaic virus. 
  • P. vulgaris 鈥楳ascotte鈥: prolific producer; 5- to 6-inch fruit on 16- to 18-inch- tall plants; resistant to anthracnose, bean common mosaic virus, and halo blight; variety name is French for 鈥渕ascot鈥 and symbolizes good luck. 
  • P. vulgaris 鈥楾opcrop鈥: vigorous heirloom that sets heavy crop of pods 6 to 7 inches long on 15- to 18-inch-tall bushes; resistant to bean common mosaic virus.
  • P. coccineus 鈥楬estia鈥: dwarf runner bean; 12- to 14-inch-tall plants produce 8-inch-long pods; if desired, leave beans to dry on plant and harvest as dried beans for chili, soups, and stews
  • P. vulgaris 鈥楻attlesnake鈥: heirloom; vines up to 10 feet long produce 8- to 10-inch-long green pods with purple speckles; drought-resistant; heat-tolerant

Harvesting

  • Harvest beans in the morning when their sugar level is highest.
  • Pick green beans every day; the more you pick, the more beans grow.
  • Green beans are picked young and tender before the seeds inside have fully developed. 
  • Look for firm, sizable pods that are firm and can be snapped鈥攇enerally as thick as a pencil. 
  • Snap or cut the beans off the plant, being careful not to tear the plant. Fresh beans should snap easily when broken.
  • Once you see the seeds inside bulging, green beans are past their peak and will taste tough.

Wit and Wisdom

  • Beans are commonly used in everyday expressions to indicate something of little value. Something that 鈥渋sn’t worth a hill of beans鈥 is not worth much. Meanwhile, a 鈥渂ean counter鈥 is a person involved in corporate or government financial decisions and especially one reluctant to spend money.
  • According to folklore, in order to get rid of a wart, rub it with a bean and cast the bean over your shoulder without looking back.
  • 鈥淪tring鈥 beans have a fibrous, sometimes tough, thread running the length of their pod that for centuries had to be removed by hand. In the late 1800s, breeders became successful in eliminating the string in most varieties; today, only heirloom beans still have a string.
  • 鈥淕reen鈥 beans, 鈥渟nap鈥 beans, and 鈥渟tring鈥 beans are all the same.
  • Not all green beans are, in fact, green. Their colors can range from purple to red to yellow to streaked variations thereof.

Do you have supports? Beans are shallow-rooted plants and can't keep them selves upright with out supports.
If seedlings fall over (and die), then that's the work of cutworms.

I have been growing green beans in my garden in my back yard every summer, but this year my family and I have been having some trouble. The beans are seeding very early. The beans seemed to be growing normal but once they reach around three-four inches the seeds become very large and the bean hollows out. In previous years our beans only reached a point like this if we left it on the branch too long. What could be the problem with our beans? Thanks.

Hi, Josie, Even before finishing reading, the first question that comes to mind is, are you rotating your crops? It's sometimes possible to get "good" crops in the same soil (area of your garden) one or two or even three years, but with each repeat year, quality slips. And the slippage accummulates. Holes in pods and hollowed seeds/beans are also caused by corn earworms and Lcyaenid pod borers鈥攇rub-like caterpillars that become small butterflies. Collect and destroy infected pods. Control with Bacillis thuringeniensis, an insecticide. And rotate.

I am growing Blue Lake green beans with some success. I am wondering why some of the leaves and turning yellow, then getting very "crunchy" and I have been stripping them off. What causes this "crispy yellow" leaves? Please HELP! Thanks, I live in zone 5b.

First make sure the soil is well drained and that the beans get lots of sun. Beans need rich soil so adding compost around the plants may help. Mosaic viruses and other diseases can also cause yellow leaves.

I planted Blue Bush Beans 2 weeks ago by seeds that I soaked in warm water over night. I planted two per hole to make sure that at least one took to sprouting. I planted in 8 holes. I only have one hole that has sprouted (both seeds) three days ago but still nothing in any of the other holes. I am also using a container to grow them in. Should I be concerned or just get a bit more patience. This is my first time growing them so I am not sure. :D

It sounds like you did everything you could to coddle the seeds. The days to germination on some bush beans are 7 to 14 days. If the soil was a little cool (under 60F) that can delay germination. You might just wait a week longer to make sure--it could be that they are just taking a little more time to get up to speed. Past then, however, you might check one of your plantings as a sample for any seed rot or insect/disease damage.

Thanks I live in Zone 8 so our soil temps should be warm enough :) I will wait one more week and then poke into the soil to see what's up with the seeds :D Thanks again!

I have planted blue lake green beans twice this season. The plants are fine one day and the next morning all the leaves are gone and only the thin stalks remain. I can only think that the leaves are being eaten by an animal. Tomatoes, peppers and other vegetables are not affected. What is eating these plants? Thanks.

Woodchucks....happened to me last year, and i caught him, although too late. Only other plant affected was sweet potato. This year i used a pepper spray and a mint and cinnamon pellet
