Pole beans are a popular summer vegetable all across the country and not without good reason! As their name suggests, pole beans require the setup of a trellis or tepee of poles to cling onto, but their vertical habit means they require less space than most other types of plants and can be grown just about anywhere. If that weren’t enough, the range of colors, shapes, tastes, and sizes of pole beans available is extensive enough that any gardener can find a variety to their liking. Almost all varieties of pole beans can be harvested at any stage in the growing process as either fresh snap beans, shelling beans, or drying beans; however, some varieties are better suited to one use over another, so be sure to research the varietals before choosing which type to grow if you are using your beans for a specific purpose.

Romano pole beans are an heirloom varietal with stringless, flat pods and high yields that are sometimes also referred to as Italian pole beans or Italian flat beans. These plants produce 6″ long pods and can grow up to 9′ tall, so make sure you have a large enough trellis available in your chosen location prior to planting. Romano beans are great for eating fresh as snap beans but can also be left on the plant until the end of the season and then stored as dry beans.

  • Yield: 0.5–1.5 lbs per plant
  • Garden Dimensions: 2–3 plants per square foot
  • Germination: 8–21 days

Seed Depth: 1–3″. Plant seeds deeper in drier soil.
Space Between Plants: 4–8″
Space Between Rows: 1.5–2′
Germination Soil Temperature: 60–80°F
Days for Germination: 8–21 days
Sow Indoors: Not recommended. Once roots start to form, beans don’t like to be disturbed.
Sow Outdoors: 2–3 weeks following the average last frost date. Pole beans will germinate in soil temperatures as low as 60°F, but the cooler the soil temperature, the slower the germination process will be.


Pole beans prefer warmer climates and do best in more southernly climate zones; however, they’ll still grow during the summer in other regions once temperatures reach approximately 60–70°F. Note that while beans can be grown for a fall harvest in warmer climates, growth slows as temperatures drop to 60°F or lower, so you may experience a loss of yield if planning on planting for the fall. While they do prefer lots of sun and warmth, yields will also start to decrease once temperatures surpass 90°F, so provide protection if you live in climates with extreme heat.


Natural: Full sun or partial shade in extremely hot weather.

Artificial: It’s not recommended that you start your plants indoors. However, if you do decide to grow inside, use strong lamps such as HIDs as beans require a good deal of light. Expose seedlings to light for at least 10 hours a day, keeping bulb at least 4–6″ from the tops of your plants to keep them from burning.

Growing Media

Soil: Prefers well-drained, nutrient-rich soil with lots of organic material. A soil pH of 6.0–8.0 will get plants growing, with an ideal range falling between 6.0–6.8.

Soilless: Seeds will germinate in nutrient-rich mixes with good drainage such as those that contain coco coir, perlite, and/or vermiculite.

Hydroponics: Will grow well in hydroponic systems that provide a good deal of support, such as an ebb and flow system, with sturdy media such as clay pellets or gravel.

Aeroponics: There’s not a great deal of data on growing pole beans aeroponically, so be sure to let us know on our contributors page if you have any success with growing pole beans in an aeroponic system!


Water: Requires moderate levels of water: approximately 1″ per week. Keep soil evenly moist but not soggy. This is particularly important in the early stages of growth as overwatering the seeds can cause damage and decrease your germination rates.

Nutrients: As pole beans tend to produce their own nitrogen (as long as the proper rhizobia bacteria are in the soil), they do not generally require the addition of this nutrient. Adding a light layer of compost or nutrient mix with higher levels of potassium and phosphorous, however, can benefit your plants if added prior to planting and once again when plants have reached about 6″ in height.

Foliar: Although not required, a light application of compost tea every 3–4 weeks can help your plants and the surrounding soil stay happy and healthy.

Pruning: One of the benefits of pole beans is that they produce high yields very quickly, so make sure to keep picking off your beans as they mature if you want to maximize your plant’s productivity.

Mulching: Apply a light layer of straw, reusable black landscape fabric, or wood cuttings around your bean plants to keep moisture and heat in your soil and suppress weed populations.

Support: Pole beans require a trellis or pole to support their growth. Plants will naturally climb, or you can help them along by twining new shoots around your support structure.

Deficiency(s): If your plant’s leaves are turning yellow and you haven’t tested your soil for rhizobia bacteria, it’s possible your plants are experiencing a nitrogen deficiency.

Rotation and Companion Plants

Rotation: While some sources suggest rotating your pole beans every year with other crops, beans can be planted in the same location for up to 3 years before relocating them. Follow your pole bean crops with members of the brassica family or lettuces.

Companions: As pole beans are a member of the Three Sisters, they will grow well with corn and squash. Also does well when planted with savory, radishes, lettuce, carrots, cucumbers, eggplant, and potatoes. Avoid beets, cabbage, kohlrabi, and members of the onion family.

Harvest and Storage

Harvest: Beans may be harvested at any stage of the growing process depending on your need, but if harvesting at maturity for fresh eating, wait until beans appear swollen and are firm to the touch. Once your plant starts producing bean pods, you’ll likely need to harvest at least once a week. For dried beans, allow the pods to dry entirely on the stalk and then remove from the plant.

Storage: Fresh pods will keep in the refrigerator for up to 2 weeks. Do not wash your beans until you are prepared to use them.

Other Info

Supporting your Beans: A great and cheap way to support your pole beans is by making a pole tepee. To make a tepee, simply place three to five poles in the ground in a circular pattern, about 6″ deep. Bring together the tops of the poles and tie together with twine or rope. Plant your seeds around the base of the poles and, as your seedlings emerge, gently wrap their tendrils around the pole. As they grow, they’ll continue their way up the pole on their own.


Preserve and Prepare

Preserve: This veggie is great for preserving for future use either by pickling, drying, or freezing depending on how you want to use them. Romano is considered a particularly good snap bean or freezer bean. To freeze, first trim off stems and then blanch by boiling beans for 4 minutes before transferring to an ice water bath. Place in freezer bags and freeze until needed.

Prepare: If eating your beans raw, trim off the stem end of the pod and steam, boil, sauté, or bake as desired. For dried beans, allow the pods to dry entirely on the stalk and then remove from the plant.


Nutritional: This veggie is a great, low fat source of nutrients that is high in vitmain(s) A, C, and K. Pole beans are also a good source of fiber and contain trace amounts of many minerals including manganese, magnesium, calcium, and iron. They’re also a good source of antioxidants.

Medicinal: As pole beans provide antioxidants to the body, some studies have suggested that they can contribute to cardiovascular health by lowering blood fat content. The vitamin K and calcium content in beans has also been linked to increased bone density and overall bone health.
