Why Pole Beans Belong In Your Garden

Pole beans remain a staple in many gardens because they are one of the easiest summer crops to grow. They thrive in heat and humidity.

As far as legumes go, they have a lot to offer because you can prepare them in many ways. 

Growing towers of pole beans in your garden will free up space because they can grow vertically. Read on to learn what are pole beans, how to grow pole beans, which beans are pole beans, and more. 

Pole Beans

Quite simply, pole beans are legumes and members of the pea family. They are green beans. They are also called vine beans, yard longs, and runner beans. As annuals, you’ll need to plant them every year. 

Pole beans are different from bush beans in that they need stakes, a trellis, or teepee to support them as they grow. Bush beans grow as a shrub or bush and don’t need extra support. 

Pole bean plants grow tall as climbing vines. They will grow to be 6 – 9 feet long with a spread of 18 inches. Some varieties grow to 12 feet. 

Stakes or bean teepees will help support their weight and their fragile roots. 

Pole bean plants also yield longer than bush beans and can produce until frost with the right conditions. 

The species Phaseolus vulgaris is commonly grown in gardens. Some common ones are Kentucky Wonder, Scarlet Wonder, Kentucky Blue, Blue Lake, Monte Gusto, and Carminat.

How to Grow Pole Beans

Growing pole beans can help you maximize garden space with the proper setup. Since they grow vertically, you just need to train the vines to climb up trellises, poles, or stakes.

Use these tips to help you have a big yield over a long harvest period. 

Growing Requirements

Pole beans are hardy plants and do well in most all climates as long as you plant them after the last frost. In most growing zones, this is in March and April. In colder regions, it might be later. You can also plant them in the summer.

How to Plant Pole Beans 

Direct sow pole bean seeds directly into the ground. It’s best not to plant them indoors because they don’t survive transplanting well. 

Also, they grow quickly, so starting them after the last frost from seed outdoors will still ensure a good harvest. 

Plant pole bean seeds one inch deep. Be sure they are three inches apart. Space rows two feet apart.

You can snip the smaller ones after they germinate and are two inches tall. Seeds take 10 – 14 days to germinate. 

Soil

Pole beans love soil that drains well. In addition to well-draining soil, be sure to amend with compost and organic matter.

Work the top eight inches of soil so it’s loose. While they’ll grow in rocky, loamy, sandy or clay soils, loose soil is ideal. Pole beans prefer slightly acidic soil to neutral soil with pH levels ranging between 6.0 and 7.0.

Sunlight

This type of bean thrives in full sunlight. Plant in an area that receives at least six hours of direct sunlight each day.

Though pole beans can survive and produce a fair crop in partial shade, they prefer full sunlight and thrive in warm soil. To get the most from your plants, maximize daily sun intake.

Water

Pole beans require about an inch of water per week until they blossom. After that, expect to water about two inches per week. If you live in a dry climate, such as gardening zone 9b, you’ll need to water more often. 

Be sure to factor in rainfall. Setting up drip irrigation on a timer is ideal.

Once your plants mature and have full leaves, it’s a good idea to mulch around the base to keep moisture in. You may also want to water in the mornings to prevent the leaves from getting too dry or too wet.

If your plants stop flowering, it’s a sign that you aren’t watering them enough.

Germination

Most pole bean varieties that home gardeners plant germinate in 10 – 14 days. Much will depend on the soil and weather conditions. 

Fertilizer

One of the reasons pole beans remain a popular crop is they are one of the easiest vegetables to grow. They don’t require special fertilizer. Pole beans naturally introduce nitrogen into the soil, but you can use compost or manure midway through the growing season for a boost.

Trellis or Stakes

In order to thrive the vines will need support. To do this properly, set up the stakes, bean teepee, trellis or other means of support, soon after germination takes place. You’ll want them to string up. 

It’s essential to have the method in place so the vines can start using the support structure early in their growth cycle.

This will help their roots to remain intact and undisturbed. They have fragile roots that you could damage if you wait to prepare support systems.

Establishing a support system for your pole bean vines doesn’t have to be an elaborate affair, but you can get creative. Some people prefer simple wooden stakes or poles set in neat rows to maintain their vines, while others use trellises or create teepee-like structures. There are also pole bean towers available.

Try not to arrange the supports too close together. Even though they grow up, they still need width to spread and grow. Many varieties have an 18 inch spread.

Too much crowding can cause disease, hide pests, block sunlight, and prevent proper drainage. Giving the pole bean plants enough room will help them thrive to their potential.

Pollination

Pole beans are self-pollinating. Their flowers have all the reproductive parts to produce bean pods. You can plant one or more pole bean plants and have a good harvest. 

Companion Plants 

While the pole bean plants will need enough space, they do well with warm season vegetables.  companion plants such as corn, zucchini plants, squash, beefsteak tomatoes, and cucumbers

Days to Maturity

When you purchase seeds, be sure to check the days to maturity so you will have an idea of when to expect harvest.

If you live in an area with a shorter growing season, choose varieties such as Kentucky pole beans and Carminat which grow quickly. 

  • Blue Lake: 63 days
  • Carminat: 60 – 65 days 
  • Kentucky Blue: 65 days to maturity
  • Kentucky Pole Beans: 65 – 70 days
  • King of the Garden Lima Pole Bean: 90 days
  • Monte Gusto: 70 – 80 days 
  • Scarlett Runner: 70 – 115 days

Pruning 

No pruning is needed when growing pole beans. However, to encourage pod development and growth, you can snip vines when they reach the top of the stake or trellis. This is encourage the plant to focus its energy on producing new beans.

Harvesting Pole Beans

Pole bean plants will keep growing beans but you must keep up with the harvest as this promotes growth. The more you pick, the more pods they grow.

On average, you can expect at least five harvests per plant. 

Another perk of choosing pole beans is the long-term harvesting opportunity. You can expect beans from mid-summer through early fall in many areas. For the best flavor, harvest in the morning. It’s best to pick every day to encourage the plants to produce more beans.

To remove the beans, carefully cut them off the plant without tearing the vines. Fresh beans, about the thickness of a pencil, should snap off easily.

Before choosing a variety to plant, think about what you want to use them for. Some varieties, such as Kentucky Wonder pole beans are string-less when they are young though pods can grow to 9 inches when fully mature. 

Young beans are tender because the inner seeds haven’t developed yet. Conversely, bulging bean pods have overdeveloped seeds sometimes making them tougher to eat.

Like with growing okra plants, the longer they remain on the vine, the tougher they become. 

If you plan to dry them, leave them on the vine longer so they start to dry out. For faster-maturing varieties, you can pick them closer to 80 days instead of 65 days like you would for eating them fresh.

Tips for Growing Pole Beans

Knowing the basics should be enough to get you started with this easy-to-grow crop. However, it’s always nice to have some helpful tips for growing better beans.

  • Fertilize after the heaviest bloom and first set of pods.
  • Use mulch or weed regularly, being careful not to disturb the root systems. 
  • When vines reach the support tops, pinch them off to refocus the plant’s energy into producing more beans.
  • If you encounter extreme heat with young pole bean plants, cover them to protect the blossoms.

What to do with all the beans?

You can store pole beans for up to seven days in the refrigerator in a crisper drawer. Or you can freeze them immediately after harvest for longer storage. It’s also acceptable to blanche, can, or pickle beans for longer shelf life.

After harvest, you can do many things. Enjoy them fresh or cooked. With an abundant crop or a mighty yield from lots of plants, you can freeze them or dry them for shell beans.

Pole Bean Varieties

Pole beans make attractive plants in any garden, especially with dainty white flowers and spindly vines. Scarlett Runner has gorgeous red flowers. 

It’s an easy way to add edible appeal to any garden, but how do you know which types of pole beans to plant?

Perhaps the most popular pole bean variety is the Kentucky Wonder; however, there are several other options, including several heirloom varieties.

If you find you like the way a certain variety tastes, plant it again the following year. Some are crunchier, milder, and/or sweeter than others. 

They are annuals which means you will need to plant them each year. 

Which is Better Pole Beans or Bush Beans

Bush beans and pole beans are two classes of green beans. Though similar crops, the plants grow differently.

Bush beans grow up to two feet and work well in compact gardens. You can harvest in a shorter time, and it only lasts two weeks.

Pole beans, sometimes known as runner beans, grow up to ten feet tall, some varieties even taller. They grow vertically, thereby saving space in a garden bed. 

Additionally, pole beans have longer harvest cycles, yield more beans, and hold up better against plant diseases. They are also sweeter than bush beans.

However, they need physical support, like trellises or stakes, and usually take an additional week to mature.

Growing Pole Beans

The most important thing to consider when growing pole beans is to plant them from seed outdoors after the last frost. They do well in spring and can be harvested in summer. Keep harvesting, and they will continue to grow.

Then you can cook them, add them to salads, eat them raw, use them in recipes, and even store them. Pole beans also grow well hydroponically, and because they grow vertically, are ideal for these setups.
