Having a narrow yard is no longer an excuse not to garden. One of the smartest ways you can try is to use vertical areas. Planting long beans on walls is a practical solution because this plant naturally likes to creep and does not require a large area of ​​land. Very suitable for residences with a minimalist concept.

By applying this technique, the walls of the house can have a dual function, namely as a planting medium as well as a natural propagation support. We can use rope, wire or netting to ensure the direction of plant growth is neater. Apart from making the house more beautiful, this method makes the care and harvest process easier because the position of the plants is very easy to reach.

The following are the steps that can be followed to start gardening long beans on the wall, quoted BrilioFood from Liputan6, Sunday (18/1).

The first key to success is choosing high quality seeds. Make sure the seeds you choose are in good condition, have no defects, and have strong resistance to disease attacks. Healthy seeds really determine how dense the harvest will be.

For planting media, use a loose mixture so that the roots can develop optimally. The ideal mixture consists of soil, compost, and rice husks or husk charcoal in a ratio of 2:1:1. Make sure the planting container such as a pot or polybag (minimum diameter 30 cm) has good drainage holes so that the water does not stagnate and cause the roots to rot.

2. Technique for planting seeds so they grow quickly

To make the sprouting process faster, soak the seeds in water for several hours or wrap them in damp tissue for 1-2 days before planting. If so, make a hole 3-4 cm deep in the planting medium and insert 2-4 seeds into each container. Cover lightly with soil then water sufficiently. Planting directly in a permanent container is much better because long bean roots are quite sensitive if moved frequently.

3. Install supports in the wall area

As a vine, long beans need a handle to grow upwards. Install stakes or supports made of bamboo or wire with a height of around 150-200 cm directed towards the wall.

The best time to install this support is when the plant is about two weeks old or when its height reaches 20-25 cm. This is important so that plants can get optimal sunlight and air circulation.

4. Daily Care Routine

Watering should be done regularly twice a day, morning and evening, especially when the plant is still in the early growth phase. Keep the media damp but don’t make it soggy. Provide organic fertilizer or compost every two weeks to encourage the appearance of flowers and fruit. Apart from that, be diligent in pulling out weeds and checking the condition of the leaves for potential pest attacks.

5. Harvest Period and Continuation of Production

Long beans are usually ready to be picked 45-50 days after planting. Harvest in stages by choosing fruit that is long and feels fresh. If cared for consistently, this plant can continue to produce for quite a long time. Planting on walls really provides a double benefit: saving space while providing a sustainable supply of fresh vegetables for your own kitchen.

Questions & Answers Planting Long Beans

1. Is a wall exposed to direct sunlight all day good for this plant?

Very good. Long beans are a tropical plant that requires full sunlight (around 6–8 hours a day) for the fertilization process. However, if the wall is made of material that retains excess heat such as zinc, make sure to leave a distance of around 5–10 cm between the creeping media (net/rope) and the surface of the wall so that the leaves don’t “burn” due to the reflected heat.

2. What types of pests most often attack long beans and how to deal with them?

The most common pest is the black aphid (Aphis craccivora) which often gathers on the tops of plants. You can deal with this naturally by spraying a very dilute solution of dishwashing soap or using a botanical pesticide from soaking garlic to keep the plants organic.

3. How do you differentiate long beans that are ready to harvest from those that are too old?

Long beans that are ready to harvest have a dense pod texture, a fresh green color, and the seeds have not yet protruded. If the pods feel soft (hollow), the color has faded to yellowish, and the shape of the seeds is very clear, it means the beans are too old and the texture will feel tough or fibrous when eaten.

4. Do long bean plants need to have their leaves pruned?

Yes, light pruning can be done if the lower leaves are too dense or touch the ground. This aims to increase air circulation and ensure that nutrients are focused on flower and pod formation, not just leaf growth.

5. Can you plant long beans on a wall in an indoor area or closed balcony?

Yes, as long as the area still gets access to sufficient sunlight (at least 4 hours of direct light). If the area is very shady, the stem growth will become very thin (etiolation) and the plant will have difficulty producing flowers. Also make sure the air ventilation is good so that the planting medium is not too damp which can trigger fungus.
