Pole Beans: Everything To Know About Growing Vertical

12 min read

Learning how to grow beans and having a hard time deciding whether to stay close to the ground with bush beans or go vertical with a pole bean variety? Pole beans have growth characteristics that provide space-saving beauty and visual interest in home gardens. Vining varieties, runner beans, and snap beans make going vertical an exciting element in any garden. 

Common beans are divided into two main groups: pole and bush beans. Bush varieties form 8-20 inch bushes, whereas pole varieties form 7-10 foot vines.

Deftly named, these climbing beans require physical support. With so many pole bean trellis options, they’re an excellent choice for gardeners with limited or unique spaces. Vertical vines can produce 2 to 3 times more than bush beans in the same amount of space!

Pole beans are more than just showy foliage with beautiful flowers, delicious pods, and plump beans. They are high in vitamins A, C, and K, folic acid, and fiber, and growing them is easy to do just about anywhere.

Both pole and bush beans are part of the same family, and the main difference is the support they need. In order to be successful, pole beans need trellises to guide the vines upward. Dozens of gorgeous varieties are available  – broad, flat, straight, curved, lavender-pink, variegated striped, fresh-eating, dry-preserving – the list goes on.

Runner and Half Runner Beans

Although runner beans (Phaseolus coccineus) are a different breed from pole beans (Phaseolus vulgaris) they are both excellent climbers. I imagine runner beans “running” up toward the top of a trellis!

Half runner beans are snap beans (Phaseolus vulgaris) and, as the name implies, half-runners have the combined growing habits of bush and pole beans. Instead of growing 7-10 feet high, half-runners grow about 5 feet tall, making trellising, vine maintenance, and harvesting a little easier.

How to grow pole beans? The large size of pole bean seeds makes planting easy and thinning sprouts isn’t necessary. They’re a great garden space maximizer and there are just a few rules to follow when planning and planting.

When to Plant

Pole bean seeds are somewhat sensitive to colder temperatures so it is best to wait to plant until soil temperatures reach at least 60 degrees Fahrenheit. Cooler soil temperatures just mean that germination will take longer but it isn’t harmful to plant in cool soil. At an ideal 70-80 degree soil temperature, germination will take about 8-10 days.

All bean seeds should be directly sown in the garden, as they do not tolerate transplanting well. Most pole bean varieties will be ready for their first harvest between 60 and 70 days after planting. After the first pick, be ready for multiple harvests throughout the season!

Where to Plant

Because they’re such amazing growers and require tall trellising, it is important to situate your trellis where it will not shade nearby plants that need full sun. A good rule of thumb is to plant trellises and tall growing plants near the north side of the garden. It is also best to install your trellis before seeding in order to avoid damaging the plant roots later.

How to Plant

Planting methods depend on the type of trellis that you choose for your space. If using a teepee or single-pole support, plant seeds 1 inch deep in mounded soil with 4 to 6 seeds at the base of each pole. If you are instead using a flat, more linear trellis, plant seeds 1 inch deep and 3 inches apart in a row along the bottom of the trellis.

If planting in rows, sow the seeds 6 inches apart in rows that are 24 to 36 inches apart.


As long as your beans have the support of a sturdy trellis, there is very little to do until harvest time. Pole bean flowers bloom in a variety of colors and their prolific blossoms are breathtaking.


They will grow in partial shade but you will likely experience a smaller yield. Full sun is ideal for healthy plants and higher productivity.


They prefer temperatures that are at least 60° Fahrenheit.

How Often to Water Pole Beans

Being shallow-rooted, they require at least 1 inch of water per week. Providing plants with consistent moisture is key, especially during flowering and fruiting. Beans in general are sensitive to moisture and can be prone to blights and molds, so it is important to avoid soaking the leaves when watering.


They prefer well-drained soil with a pH of 6.0 to 6.8. Mulching the plants with a fine mulch like compost or shredded leaves will help retain soil moisture and inhibit weed growth.


Beans are classified as “light feeders,” which means that fertilizing at planting time should be sufficient for your plants’ nutritional needs. Aged manure is an excellent fertilizer to incorporate into the soil before planting. Spread the manure across the planting area at a depth of about 3 inches and work it into the soil. Once the plants grow to about 4 inches tall, side-dress the plants with more aged manure.

Beans are also nitrogen fixers, which means that they absorb nitrogen from the air and release it into the soil. Because of this, it is important to avoid treating your plants with commercial fertilizers that contain large ratios of nitrogen. If you are using a prepared fertilizer, look for one that has a low nitrogen to phosphorus and potassium ratio like 5-10-10. Applying nitrogen fertilizer and combining that with the nitrogen fixed by beans will cause too much leaf and stem growth and may prevent bean growth and production.

Trellising Pole Beans

Pole beans need strong support and there are lots of trellising options out there for managing your vines. Many garden centers sell pre-made trellises, but creating your own out of recycled odds and ends can be really fun.

Some ideas for trellis materials include:

  • Bamboo canes
  • Branches and sticks from trees
  • Wire fencing
  • Steel rebar
  • Netting
  • String
  • Wire

From these materials, you can build arches, walls, fences, or round structures with multiple legs for the climbing vines. You could also use existing structures like tall fences and poles for a cost-saving and beautifying addition to your space.

The vines will climb and wind their way around any structure, so don’t worry about needing to train them upward.

More natural options include using growing corn stalks or giant sunflowers as supports. Corn and squash are the traditional “sisters” to beans and all three can be grown together. Plant a few bean seeds at the base of a corn plant when it is about a foot high, and the cornstalk will support the bean vines while the squash shades the ground and keeps weeds at bay.

Harvesting and Storing

Harvesting Pole Beans

Harvest times depend on whether you plan to eat the shelled beans or snap bean pods fresh, or will preserve the beans for dry use.

For snap beans, harvest the pods when they are young and before seeds begin to bulge inside the pods. Wait a little longer for fresh shell beans; harvest them when the pods begin to dry but the seeds are still plump and glossy. For dry beans, wait to harvest until the leaves have turned brown or fallen to the ground. Do a test bite on a couple of the seeds, if they barely dent, they are ready. The pods should be completely dry.

Storing Pole Beans

Fresh shelled or snap beans can be blanched and frozen, canned, or pickled to preserve them for winter eating. Completely dried beans should be stored away from heat and light in sealed containers like mason jars.


Pole beans can be hit by diseases caused by bacterium, fungi, or viruses and several common pests can also ruin your harvest.

Below are some common pole bean pests and diseases. For more in-depth coverage, check out the Troubleshooting section of How to Grow Beans: The Ultimate Guide.


As soon as warm weather arrives, Mexican bean beetles emerge from their winter slumber to feed on bean plants. Larvae and adult beetles snack on the leaves, leaving them looking lacey and skeletonized. Handpicking can control them, but if you have a serious infestation, you may need to use a neem oil spray or sprinkle plants with diatomaceous earth.

Aphids and spider mites pierce individual plant cells and feed on plant juices. To identify damage by these pests, look for curling, yellowing, or misshapen leaves. The undersides of leaves and plant stems are particularly appealing to aphids and spider mites. Neem is effective for controlling these pests. For a preventive option, try interplanting sweet alyssum with your beans. Sweet alyssum flowers attract aphid-loving predators!

Leafhoppers also feed by puncturing bean leaves and sucking out plant juices. A neem oil spray or sprinkling plants with diatomaceous earth will keep these pests in check.


Bacterial blights can develop when leaf surfaces are constantly wet or damp. Encourage airflow around your plants by reducing overcrowding. Water close to the ground and avoid spraying the foliage.

Bean common mosaic virus is identified by discolored leaves in mosaic patterns of light and/or dark green. This virus is spread by aphids and leafhoppers. Sadly, once your bean plants are infected, there is no treatment available. Inspect your bean leaves regularly and treat for aphids and leafhoppers as soon as possible.

White mold is caused by a fungus and looks like typical white, fluffy mold. Cool, wet weather encourages this disease. Commercial fungicides could be used but there aren’t many organic options. For prevention, encourage airflow among your plants to reduce moisture on the leaves and the soil surface.
