Soybeans In the Garden: How To Grow Them

Soybeans are a plant that was first grown in eastern Asia. You can eat the plant, which can come in various forms, such as soy flour, soy milk, tofu cheese (made from soy milk), etc. This plant has many health benefits since it is packed with protein, fiber, vitamins, etc. Moreover, many vegans worldwide use this plant daily to fulfill their recommended dosage of nutrients. 

Since this plant has mainly become popular due to its benefits, many people got interested in growing it themselves. You can quickly grow and maintain it, but you need to know a few things before you plant your first soybeans. 

Plant it in the spring 

Since soybeans don’t tolerate cold soil, it will be best to plant US soy varieties in your garden just when spring arrives. You must ensure that the soil is not too cold for them (below 16 degrees Celsius), or they won’t sprout. Wait a couple of days when spring arrives to get the best results. 

The ideal soil temperature for growing soybeans is around 21°–25° Celsius (room temperature). If the summer is too hot in your region, there might be a chance that your soybean plant won’t sprout (the same goes for colder areas). You can also plant your soybean in partially shady spots of your garden to prevent it from overheating. 


When it comes to the perfect soil for planting your soybean plant, the PH should be around 6.0–6.8. Moreover, it would be best if the soybean plant is planted in soil with a good drainage system since excess water can be a problem for this plant. 

When it comes to the type of soil itself, you shouldn’t worry about it as much. Soybean plants can grow in almost any soil, even the poorer ones. To determine the PH levels of your soil, you can do a simple test at home. Take some soil from your garden and put it into two separate containers. Put vinegar in one, and add distilled water and baking soda. 

If the container with vinegar starts bubbling, you have alkaline soil (7-8 PH), and if the other container starts bubbling and the first one doesn’t, you have acidic soil (5–6 PH). 

Planting soybeans 

When planting your soybeans in your garden, you need to consider the space between each of the soybeans you plant. You should leave enough room for the roots to develop properly. The ideal distance between two soybean plants should be 5–10 cm. Moreover, the depth of the soybean you plant should be anywhere between 2.5 and 5 cm. 

You also must remember that you cannot plant soybeans in the same soil as some plants. For example, you shouldn’t plant soybeans in the same soil you planted onions and garlic because they may not sprout. Instead, you should plant them in the same soil as your cucumbers, bananas, corn, strawberries, etc. 


When you are planting your soybean, make sure that the soil is not wet beforehand. Once you plant it, you shouldn’t water it heavily because it may damage the seed. The seed may crack open and not be able to produce roots. Instead, you should water it just a little bit at a time. 

When your soybean comes to the surface, you should water it regularly, but ensure that the soil doesn’t have too much water. You should also be aware that overhead watering (watering the top of the plant) can cause damage to it. Avoid using water that is too hot or too cold water because the plant may “get sick” and not make any progress. 


When planting your soybean, you should add aged compost to help it grow and make progress. You should also add aged compost in the midseason. Moreover, avoid using fertilizers since many of them contain nitrogen. Soybeans produce their own nitrogen – if you add fertilizers, it may become too much for these plants to handle. 

While growing them in your garden, ensure there is no weed around. If weed occurs, carefully remove it because it can damage the soybean’s root system, causing it not to develop properly. 

You should also avoid touching your soybean plant when wet because it may cause a spread of bacteria and fungi that can damage the plant. Other than that, few diseases can attack this plant. 


You will know the plant is ready to be harvested when the pods are green and plump. You will likely have a soybean product around 60–70 days after planting it. The products on one plant usually mature simultaneously – when you see that your soybean has matured, you can take the whole plant and leave it to dry. 

You must not eat raw soybeans because they contain harmful ingredients – boil them for at least 5 minutes before you eat them. 


Soybeans are a great source of lean protein and other nutrients. If you are a lover of soybeans and want to grow them in your garden, follow the steps we have prepared in the text above.
