If you’re looking to add a nutritious and delicious addition to your container garden, look no further than the broad bean. These legumes, also known as fava beans, are easy to grow in pots and provide a bounty of tasty pods that you can enjoy throughout the growing season.

Broad beans are high in protein, iron, and fiber, making them a nutritious choice for your garden. 

Growing broad beans in pots requires a few special considerations, so read on for our full guide to successfully planting, caring for, and harvesting your own homegrown broad beans.

Selecting The Right Pot And Soil For Broad Beans

Broad bean plants need plenty of space to grow healthy and full-sized pods, so be sure to choose a pot at least 12 inches deep to accommodate the long roots of broad beans.

As for containers, you can opt for plastic, ceramic, or even fabric pots, just make sure they have drainage holes to avoid waterlogged soil. 

Raised beds can also be an option for growing broad beans, as long as the beds are at least 7 inches deep.

Fill the pot nearly to the brim with quality soil that drains well—peat moss or compost-enriched soil works best. Or you can make your own with equal parts perlite, compost, and peat moss. 

For heavier soils, consider adding some coarse sand or perlite for better drainage.

Planting Broad Bean Seeds

Depending on the climate and region, different varieties of fava beans can be cultivated.

These plants can get quite large so it’s important you select short bushy varieties.

Some of the best varieties for growing in containers include ‘Aguadulce’, ‘Bell’, ‘Crimson Flowered’, ‘Diana’, ‘Red Epicure’, ‘Robin Hood’, ‘Stereo’, ‘Sutton’ and ‘Sweet Lorane’. These varieties are all relatively short, making them ideal for container gardens.

Take your broad bean seeds and soak them overnight in lukewarm water to soften the seed coat before planting. This will help speed up germination and ensure even growth.

Another option is to pre-germinate the seeds by placing them on a damp paper towel in a sealed plastic bag. This encourages early sprouting before planting them in pots.

Once soaked, plant two or three seeds per pot, about 1 inch deep into the soil. Broad beans should be planted with the pointed end facing down and the flat end facing up.

Cover the seeds with a thin layer of soil and water gently until moist but not soggy.

Place your pots in a sunny spot indoors or outdoors where they will get plenty of light and warmth – temperatures should be around 15°C/59 F for best results.

Keep an eye on your pots over the next few weeks to make sure they don’t dry out; if necessary give them an occasional watering to keep them moist but not wet. After about 6-8 weeks you should start to see shoots emerging from the soil – these are your broad bean plants!

Broad Bean Growing Stages

Here’s an easy breakdown of the stages of growing broad beans in containers.

Planting: Plant your broad bean seeds in compost-rich soil early in spring, about 4 inches apart and 1 inch deep.

Germination: Broad bean seeds usually germinate within 7 to 10 days after planting, depending on the temperature and moisture levels.

Growth: As the plants grow, they will need to be supported with stakes or cages as they can reach up to 2 feet tall. Water regularly and add mulch around the base of the plants to help retain moisture and suppress weeds.

Flowering & Pollination: When the plants reach 8-10 nodes (about 12 inches high), they will produce flowers that are self-pollinating so you don’t need to do anything special here!

Harvesting: Depending on the variety, your broad beans should be ready for harvest between 80-100 days after planting. The pods should be full when harvested and can be eaten fresh or frozen for later use.

Conditions For Growing Broad Beans In Pots

Sunlight requirements for healthy growth: Broad beans need full sun to partial shade in order to thrive. They will not flower well in hot, dry conditions but can tolerate some shade.

Optimal temperature range: Favas need temperatures between 60 and 65 degrees Fahrenheit for optimal growth. Some varieties are frost-resistant and can handle cold temperatures better than others.

Humidity and moisture considerations: Broad beans require moist soil but should not be overwatered or allowed to stand in waterlogged soil for too long as this can cause root rot and other problems. It is best to water them deeply but infrequently so that the soil remains moist but not soggy.

Providing adequate support for vertical growth: Since broad beans grow tall, they need some kind of support such as stakes or trellises to keep them upright and prevent them from falling over due to wind or heavy fruits. This will help ensure that your plants get enough sunlight and air circulation for optimal growth and production of pods.

Watering and Fertilizing Broad Beans in Pots

Broad beans need regular watering during their fast growth period, especially when grown in containers. The soil should be kept moist but not soggy, so check the soil moisture levels regularly. If the soil is dry, water deeply until the excess moisture drains out of the bottom of the pot.

Once established, broad beans can tolerate some drought conditions but will benefit from occasional deep watering during prolonged dry spells.

Broad beans appreciate a little extra nutrients now and then, so adding some fertilizer once in a while can help promote growth and keep your plants healthy.

Compost tea or liquid fertilizer is ideal for broad beans, as they are sensitive to synthetic fertilizers.

Use a balanced fertilizer such as 10-10-10 or 5-5-5 at planting time and again when flowers appear and pods start forming.

A couple of tablespoons per gallon of water should be enough to feed your plants without overloading them with too many nutrients.

Pruning and Training Techniques for Container Broad Beans

Broad beans don’t need much pruning but if the plants become too large and crowded, you can pinch off some of the tips to encourage bushier growth.

Pruning should be done regularly throughout the growing season, starting when the plants are about 6 weeks old.

You should also trim off any dead leaves or flowers that appear on the stems. This will help keep your plants healthy and promote more vigorous growth.

How to support broad beans growing in containers?

You can use stakes, trellises, or cages to provide support for your plants. Make sure that the supporting structure is sturdy enough to bear the weight of the plants and their fruits.

Training your broad bean plants for vertical growth is another way to increase yields in containers.

This can be done by tying up tall stems with twine or string so that they grow vertically instead of sprawling outwards across the ground.

Doing this will help ensure that all parts of the plant receive adequate sunlight and air circulation, leading to healthier growth overall.

Pest and Disease Management in Container-Grown Broad Beans

The most common pest that affects broad beans is the black bean aphid. These small insects feed on the sap of the plants, causing stunted growth and yellowing of leaves. Other pests include slugs, snails, caterpillars, and thrips.

There are several natural methods for controlling pests on broad beans. Hand-picking bugs off of plants is an effective way to reduce insect populations.

Companion planting with certain herbs such as dill or basil can also help repel some insects from attacking your plants. If natural methods do not work, chemical pesticides may be necessary to control pest populations.

Broad beans are susceptible to various fungal diseases such as blight, mosaic virus, fusarium root rot, powdery mildew, and anthracnose.

To identify these diseases look for discolored spots on leaves or stems or wilting of foliage.

Treatment will vary depending on the disease but generally involves removing affected parts of the plant or spraying with fungicides or other chemicals approved for use on edible crops.

Harvesting and Storing Broad Beans

The best time to harvest broad beans is when they have reached full size but before they start to yellow or dry out. The pods should be firm and plump with the seeds inside easily felt through the pod walls.

They should look like they’re ready to burst open when gently squeezed.

If you wait too long, the seeds will become tough and starchy.

When harvesting broad beans, use both hands to gently pull off each pod from the plant stem. Be sure not to pull too hard or you may damage the plant stem or other pods still attached.

It is best to pick your broad beans early in the morning when they are at their freshest and most flavorful.

Once harvested, it is important to handle your broad beans with care as they are quite delicate.

To preserve freshness, store them in a perforated bag in the refrigerator for up to five days or blanch them and freeze them for up to three months if you plan on using them later on in recipes or preserving them for future use.

Broad Bean Growing Problems

Broad beans can be subject to several problems if not grown correctly. If you’re having trouble getting your plants to thrive, here are some tips for troubleshooting common issues.

Dealing with Nutrient Deficiencies

Broad beans need plenty of nitrogen and phosphorus to grow well, so make sure your soil is rich in these nutrients. Compost or manure can help provide the necessary nutrients, as can fertilizer specifically designed for legumes. If you’re still having problems with nutrient deficiencies, foliar feeding may be an option.

Addressing Overwatering or Underwatering Issues

Broad beans don’t like their roots to stay wet for too long, so overwatering can cause root rot and other issues. Make sure your pot has good drainage and water only when the top inch of soil is dry. On the flip side, underwatering can cause stunted growth and yellow leaves. To avoid this problem, check the soil every few days and water when needed.

Tackling Common Pest and Disease Problems

Common pests that affect broad beans include aphids and slugs. Aphids can be removed by hand or treated with insecticidal soap or neem oil sprays. Slugs should be picked off by hand or repelled using beer traps or diatomaceous earth barriers around the base of the plant. As far as diseases go, chocolate spot and rust are two common problems that affect broad beans; both can be treated using fungicides if necessary.

Revitalizing Struggling Plants

If your broad bean plants are struggling despite all your efforts, it may be time to give them a boost with some fertilizer high in potassium and phosphorous (such as a tomato fertilizer). You could also try pruning any dead leaves or stems to encourage new growth; this will also help keep disease at bay. Finally, providing structural support such as stakes or trellises may help keep your plants upright during windy weather.

Final Thoughts On Growing Broad Beans

Growing broad beans in containers requires careful planning and maintenance to ensure a successful harvest. It is important to provide your plants with adequate sunlight, air circulation, water, and nutrients while protecting them from pests and diseases. Regular pruning and support may also be necessary to keep your broad beans healthy. With the right care, you can enjoy fresh, delicious broad beans all season long.

FAQ And Growing Tips

How many broad beans do you get from 1 plant?

Depending on the variety, it takes about 80 to 100 days for broad beans to grow. Planting 4 to 8 broad beans per household member is recommended for optimal yield. Each plant can produce up to 180 beans!

Can broad beans be grown indoors?

Broad beans are usually sown in late winter (indoors or outdoors with protection) or spring (outdoors), for summer harvests. Planting fava beans direct into outdoor containers can be done in two windows during the year – from mid-fall to early winter and then again in late winter/early spring.

In October and November, broad beans can also be sown outdoors and undercover, while in January and February they can be sown indoors and undercover.

Do broad beans need to climb?

Broad beans do not necessarily need to climb as they are usually self-supporting and do not climb on their own. However, if you want to maximize the yield of your broad bean plants, you can provide a support structure for them to climb on. This can help prevent the heavy stems from bending or even breaking under the weight of the beans. Additionally, providing support can also help with pest control by making it harder for ground-dwelling pests to access the plants.

Can you eat broad beans straight from the plant?

When broad beans are young and tender, you can enjoy them by simply removing the outer pod and consuming the inner beans. These young beans are commonly referred to as “green beans” or “baby broad beans.” As the beans mature, their texture becomes denser and their flavor can become slightly bitter.

At this stage, it is recommended to remove the outer skins of the beans before consuming them. This can be done by blanching the beans in boiling water for a few minutes, followed by transferring them to an ice bath. The skins can then be easily peeled off to reveal the bright green inner beans, which can be cooked and enjoyed in a variety of recipes.
