2. The drainage of the soil should also be taken care of in advance. You can sow the seeds either half or one inch deep and cover it up using light soil. 3-4 seeds can be sown at one place and the weaker ones can be removed on attaining a height of 4-5 inches.
3. Planting the seeds 6 inches apart will cause it to germinate within just a few days. Under suitable conditions, the seeds can germinate within just two days although they might even take between 6-7 days.

How to Plant Cluster Beans in Containers?

The average height of cluster bean plants is between 1 to 2 meters. It grows upright and spreads branches which bear oval shaped leaves.

The plant bears pink, blue, white and yellow hued flowers and they create shiny green seedpods which is the reason behind its unique nomenclature.

Once the young cluster bean plants reach a height of 4-inches, you need to nip off weaker ones so that the stronger plants stay intact.

Being a warm season crop, the water content of the soil tends to evaporate quickly and this creates the requirement of mulching especially when the crops are being grown in containers.

• At the time of sowing seeds, the soil should have a thin layer of organic mulch. You can supplement the mulch once the plants attain the size of 6 inches so that it gets about 4 inches thick. 6-8 hours of direct sunlight is required by the cluster bean plants and they do not deliver adequate results when placed in shades regions.
• The daytime temperature ideally needs to be around 30 Celsius. However, it is imperative to note here that the plant yield falls once the temperature crosses over the 40C threshold.

Summers are pretty windy in India and that is why the cluster beans require support which can be offered in the form of staking.

This however becomes a luxury you can clearly avoid under normal wind conditions. Cluster beans grown in containers can easily attain a height of 3-5 feet.

First sign of flower appears 50-60 days following germination and during this time you need to add some organic manure such as vermicompost to the container soil.

Until then, you can conduct your routine irrigation process using Jeevamrut, Amrut Jal or similar organic soil conditioners every 12-15 days.

Since cluster beans are not heavy eaters, you don’t need to add compost to the soil before they start flowering.

While growing cluster beans in containers, you need to choose a pot which is at least ten inches deep. The ideal level of soil pH is between 6.5 to 7.5.

Pests and Diseases

Two of the most common pests which can infect cluster beans are pod borer and leaf-hopper. They can cause a variety of diseases that might crop up anytime between the seedling to the pod formation stage. Let’s take a brief look at the pests and diseases caused by them:

Pests – The most popular pest which can wreak havoc to your cluster beans is termites. They tend to damage the plants by eating its stem and root which ultimately causes poor plant stand. You can control termite infestation by using chlorophyriphos with irrigated water. You can also hinder other soil borne insects by applying chlorophyriphos during last ploughing and prior to sowing.

Aphids, jassids and white flies are small insects which suck the sap secreted from cluster bean leaves. As a result, the leaves tend to curl down and their colours change to pale yellow, bronze or white.

On severe infestation, the plants might wither down completely. You can tackle this situation by applying water mixed with dimethoate, imidacloprid, malathion or monocrotophos.

Diseases – First comes Alternaria leaf spot disease which is triggered by the Alternaria cyamopsidis fungus.

The disease symptoms mostly appear on the leaf blade and bear a dark brown shade. These irregular spots might have a diameter ranging from 2-10 mm.

The second disease in our list is bacterial blight which is caused by bacterium Xanthomonas cyamopsidis. This infestation is popular during the kharif season and can be seen at the surface of the Cluster bean leaf.

Powdery mildew is another popular disease which plagues the cluster bean plants and is caused by the Erysiphe polygoni fungus.

The disease symptoms initially take the shape of white powdery growth encompassing the leaf surface. This growth comprises of the fungus and the spores. Spraying wettable sulphur spray can help in gaining an edge over this disease.

Last but not the least comes Anthracnose which is characterized by black spots appearing on the petiole, leaves and stem of the plant.

You can deal with the same by spraying a solution of 2 kg Zineb fungicide mixed with 500L of water.

How Many Cluster Beans per Plant?

It depends on the variety and healthy of the plant. Cluster bean plant has several pods. You can expect more than 10 pods per plant.

With regular watering and fertilizing during the growing season, you can expect good yield from the plant.

Cluster Beans Companion Plants

Eggplant, marigold, pumpkin, tomatoes and radish can be grown along with cluster beans.

Companion planting ensures to deter pests, suppress weed growth, helps to use leftover space and attract pollinators.

How to Grow Cluster Beans from Seeds?

First step is to ensure you get cluster bean seeds from a trusted source that offers high-quality seeds, as seed quality impacts healthy growth of the plant.

While choosing seeds look for seeds that are plump, healthy, and have no signs of damage or disease.

You can sow these seeds directly in well-drained fertile soil to germinate. Initially, water the soil so it stays moist most of the time. When the plant matures you need to increase watering frequency.

During germination stage provide ideal temperature around 30-35C.

With required amount of sunlight, water and fertilizer you can expect the harvest in 60-70 days.

How Long Does it Take for Cluster Beans to Flower?

After germination you can expect the cluster bean to flower within 8 weeks or 50-60 days.

At this time, the plant will need rich source of nutrients that can be supplied by adding organic fertilizers or use mushroom compost in your raised bed to enrich the soil.

You can also use liquid fertilizers so that roots can quickly absorb the nutrients.

Follow the instruction labeled on the fertilizer pack.

Note: Over-fertilization can result in yellowing of leaves.

How to Take Care of Cluster Beans?

To have a healthy yield, you must ensure to provide essential requirements for the plant growth.

• Cluster Beans plant thrives when exposed to full sunlight for about 8 hours. Choose a sunny spot to grow this veggy.
• Garden soil should be well-drained; this will avoid overwatering and root rot. At the same time it should be able to retain required moisture.
• Mulching around the cluster bean plant with hay grass or dried leaves will improve water retention ability of the soil. It also avoids weed growth.
• While planting seeds in the soil, you’re advised to mix old compost with the soil. And when plant matures, you must enrich the soil with more well-balanced organic fertilizers. Particularly, during growing season you should apply fertilizers to encourage plant growth.
• Check for pests and diseases regularly. Use homemade pesticide to get rid of pests.
• Once the pods are ready to harvest, trim them using a sharp knife.
