Yardlong beans, asparagus beans, Chinese long beans are different names for what is commonly known as long beans. This is a tropical and subtropical climate vegetable which is a favorite vegetable in Asian countries. The bean pods generally grow around 12-20 inches and are tender, crisp with a beautiful texture. You can eat it stir fried, pan fried, steamed and in curries. You can even eat it raw. But in raw form it tastes best when you grow it in your own Organic Terrace Garden. One of the very interesting aspect of this plant is that it grows quickly and fruits vigorously. You need to harvest on a daily basis as they fruit on a daily basis. The best part is that Growing Long Beans in Containers is super easy. It needs very basic care and is quite hardy in nature. In this post I am not only going to guide you on how to grow long beans in containers and pots, I am also going to give you some tips, which will make Growing Long Beans in Containers a fun activity for the entire family.
By the way in case you are new to Organic Terrace Gardening I recommend you to read about the things you should consider before starting your Organic Terrace Garden and a Beginner’s Guide to growing vegetables in containers.

Before Sowing Long Bean Seeds in Pots
Yardlong beans are climber plants. Within 10-12 days of developing true leaves they start to develop vines which starts climbing on any support that they get. This support is generally strings hanging loosely from top of the trellis. These plants grow very fast. Hence you must be prepare the trellis structure for the plant to climb as soon as you sow the seeds. It would be better to make the trellis even before sowing long bean seeds in pots because sometimes it is not possible to put up a structure at some places and if you cant move your container your plants get stuck in a place where they cant climb. And that is a disaster. Hence make sure you have a structure ready for climbers when you are Growing Long Beans in Containers.
Choosing Container for Long Beans
You don’t really need very big containers to grow long beans in your Organic Terrace Garden. You can use a 10 liter container to grow 2 plants. Just make sure that the depth of the container is 8-12 inches. Anything smaller than that would not give a good harvest and anything bigger than that would not boost your harvest significantly. The container can be anything from a un-glazed earthen pot to a plastic tub. Anything works as long as you take care of the minimum depth requirements of the container. Depending on the surface area of the container you can plant multiple long bean plans. If you are planing in a box type container, keep the distance between two plants 1 ft and between two rows the distance should be kept at 1.5 to 2 ft. If your containers is more of a bucket or a pot then plants can be planted closer; but not more than 2-3 per container.
Seed Sowing and Germination
We treat Chinese Long Bean seeds with Amrut Jal before sowing. We simply soak the seed in Amrut Jal for 24 hours before sowing. This helps in faster germination. Amrut Jal also helps in protecting the seed from fungal attack. However this step is not a must. You can alternatively soak your seeds in lukewarm water for 20-30 minutes before sowing. Even this step can be bypassed if you wish to.
It is always a good idea to fill up your pot in the day time with potting mix to warm the soil and sow the seeds in the evening in the warm soil. To sow the seeds make small holes of 1/2 to 3/4 inch depth with your finger or any blunt object like back of a pencil. Place one to two seeds in the hole and cover it with potting mix and compress the soil gently. Water thoroughly and you are done. Growing Long Beans in Containers is really simple, but you have to be a little careful during the germination period. Make sure that the soil is always moist and never becomes dry. If the sun is too harsh during day time cover the pot to protect the soil from drying during noon, but make sure that air is circulating well. Also don’t over water. It may cause the seed to rot. If it is raining continuously and heavily during this time cover your pots. If you just take care of these things, your seeds should germinate in 3-7 days time.
Growing Your Long Bean Plants in Containers
When your seeds have germinated all you have to do is water them regularly to keep the soil moist all the time. When the plant grows to around 5-6 inches of height mulch your pot with organic material. This will retain moisture and prevent weeds from growing.
When the plants have grown to around 5-6 inches, they are vulnerable to heavy winds. So you need to stake them til they develop their vines and start climbing. Use any small stick of about 10-12 inches of length for staking. Just lightly tie the plant to the stake near the tip with a soft string. We use jute string for skating as it is soft, natural and cheap.
When the plant develops vines it will automatically start climbing around the strings in your trellis. You may also train the plants manually to the nearest string. Make sure that there are not more than two vines on a single string. If there are any flower pods when the plant is not even 2 ft tall just remove them. Let the plant focus on growing first. When the side vines have two to three sets of leaves pinch the tip. Pinch the tip of main vine when the vine has climbed more than 6 ft. Pinching the tips is not a absolute requirement. But when you are Growing Long Beans in Containers, pinching tips at the right time will help in growing a bushier plant and give you more produce. However you don’t have to religiously do it. Just do how much ever you can.
Fertilization and Pest Care
Asparagus beans and not too heavy feeders and will grow well from the nutrients in your potting mix. But to keep a good supply of nutrients and micro-nutrients in the soil and to keep the soil alive by providing enough microbial activity water you plants with a cow dung based solution like Amrut Jal or Jiwamrit every 5-7 days during growing period. When the plants begin to flower supplement your soil with good quality compost and additionally you can increase frequency of Amrut Jal watering. To apply compost remove your mulch layer. Loosen the top 1 cm of soil and add good quality compost. Add about half a liter of compost per plant. Put the mulch layer back again. When you loosen the soil you’ll notice that there are feeder roots even in the top one cm of the soil. Hence do not dig any deeper than 1 cm as you’ll be disturbing more roots if you do so.
Use Amrut Jal, Jiwamrit or Panchagavya as a foliar spray every 10-15 days before fruiting and every 7 days during fruiting. This keeps the foliage healthy and fruits become better due to direct absorption of nutrients.
Whether you are Growing Long Beans in Containers or on the ground, no matter what you do aphids will attack your plants. Ants will also attack your pods and flowers and will help the aphids to spread. Check each morning for signs of aphids or any other pests every morning. If the infestation is not too much then wait out for a day or two to see if ladybugs have arrived in your garden for feasting on the aphids. In case you don’t want to wait you can always wash the aphids off with a spray of water. If the infestation is towards the higher side then use neem spray once every 7 days and you’ll be okay. Just make sure that you spray it very early in the morning or late in the afternoon. Otherwise it may cause leaf burns. Drop some turmeric powder on young pod, flowers and vines to control ants.
Harvesting Long Beans
Long beans need to be harvested at the right time to get best taste and texture. Leaving them a little longer in the plant makes it loose it moisture and texture. Generally it takes about 9-10 days for the fruit to be ready after flowering. Your plant will flower and bear pods daily. So harvest your yardlong beans also regularly. Just pull them using your thumb and index finger gently and they will separate from the plant.
Plant your beans every 15-20 days throughout the season to get uninterrupted supply of healthy and fresh long beans. We also plant them with other vegetables like pumpkin, eggplants and tomatoes, so that while we enjoy the great taste of long beans they are busy helping other plants. Long beans belong to legume family of vegetables and they fix nitrogen deficiency in the soil. This helps other plants which feed on nitrogen from the soil.
At the start of this post I told you that Growing Long Beans in Containers is super easy and you are most likely to agree with me on that now. But here are some fun do’s that would make Growing Long Beans in Pots even more interesting for the entire family. One of the tings that you can do it to use the long bean plants as a decorative plant. Just design your trellis in a way that the support climbing strings for the beans make a great visual design. Keep the color of the string red of orange and when the green long beans plants start climbing on them, they do make a very pretty picture.
Another fun activity that you can do with the kids is to find the longest bean. Get your kids to do the harvesting while you are doing other important things like watering the plants. Kids will learn to differentiate between mature and immature pods when the harvest regularly. Then check who has got the longest bean pod. Declare her the winner for the day. You’ll notice how kids start to take more interest in garden with such activities.
I am sure with the information you have got from this post you’ll be successful every time you are Growing Long Beans in Containers. And I am also sure if you have never grown or eaten long beans you’ll now be roaring to go and plant your first long bean seed. As a further motivation I’ll be posting a simple yet delicious recipe with long beans in my next post. Stay tuned and stay blessed.
